Can someone please answer this reddit post, thank you: https://www.reddit.com/r/webdev/comments/w5tm96/a_box_with_messages_not_working_properly/

[uneven panther]

I think your code is PHP and someone with PHP knowledge will help you. Mentioning this so anyone with PHP knowledge can answer this.

[quartz dust]

It’s actually JS but ty I really need some help with this.

[uneven panther]

Got it, so to solve your problem someone might need to access other files of your program. I am relatively new to the world of IT and don't really know anything other than Python so, I can't help you. Also, Post this on Stack Overflow since someone there might know the answer.

I've been trying to create a to do list using tkinter but to no success. I've seperated my code into 2 frames, the header frame and the tasks frame.

However I wasn't able to make my tasks show up, because as the tasks' list got updated, the Event Frame didn't reload. So it only sees an empty dict. How can I append my tasks to the tasks dict and also reload the execution of the EventsFrame class?

class HeaderFrame(ttk.Frame):
    def __init__(self, container):
        super().__init__(container)
        # set up grid layout
        self.columnconfigure(0, weight=1)
        self.columnconfigure(0, weight=3)
        self.columnconfigure(0, weight=2)
        self.__create_header_widgets()

    def __create_header_widgets(self):
        
        # Global Settings
        options={'padx':20, 'pady':10}
        glob_font={'font':('Segoue UI', 35)}
        
        # Time User Input
        hours = tk.IntVar()
        minutes = tk.IntVar()
        seconds = tk.IntVar()

        event = tk.StringVar()


        ttk.Label(self, text='To-Do List', **glob_font).grid(row=0,column=0,columnspan=2, **options, sticky='W')
        
        def add_to_lists(event_text, hrs_text, minutes_text, seconds_text):
            tasks[event_text] = [hrs_text, minutes_text, seconds_text]
            task_entry.delete(0, tk.END)
            print(tasks)

        ttk.Button(self,text='Add Event',width=13, command= lambda: add_to_lists(event.get(), hours.get(),minutes.get(), seconds.get())).grid(row=1, column=0, sticky='W', **options)```

class EventsFrame(ttk.Frame):
    def __init__(self, container):
        super().__init__()
        inc = 0     
        for task, dur in tasks.items():
            self.rowconfigure(0, weight=1)
            ttk.Label(self, text='{} {:02d}:{:02d}:{:02d}'.format(task, dur[0], dur[1], dur[2])).pack()```

tasks = {}

            self.title('strictly | A miminalist todo and timer')
            window_width = 850
            window_height = 400
            self.geometry(f'{window_width}x{window_height}+{1050}+{50}')
            self.minsize(width=500, height=200)
        window_config()

        self.rowconfigure(0, weight=3)
        self.rowconfigure(0, weight=2)
        self.rowconfigure(0, weight=1)

Hey

I have a question

I wrote a general python code... now I want to use it in Tkinter.... It is like a question and answer based code... where the display box will ask you few question and you need to provide input as per it ...... but I am confused how can I make the display box in Tkinter to display the questions and then act as an text box that can accept input as well?

If you need code.. I can provide it

[sonic swallow]

Hello, I want to know if I use PyQT **open-source version **for creating apps in Python, am I legally allowed to publish apps?

[mighty frigate]

@sonic swallowbefore looking for an answer, how how you planning to distribute your app ?

PyQt opensource is under GPL

https://riverbankcomputing.com/commercial/license-faq

https://www.gnu.org/licenses/gpl-faq.en.html

[sonic swallow]

Perhaps thinking on Play Store/App Store, but wanted to confirm the limits.

[sonic swallow]

Thanks.

Also, is it possible to build elegant apps like Notion/Evernote in Python TKinter(if not exactly, then which library to be used?)

[ionic nacelle]

https://paste.pythondiscord.com/elucujuroh
@static cove

[static cove]

ooooooooh, okay. I see now. So the function you want to run is in a different class than the subclassed QThread, right?

[ionic nacelle]

yep

how do I fix it

[static cove]

So, for this I wouldn't subclass QThread because the function won't live in QThread.

You want to use this kind of pattern instead:

class Worker(QObject):
    signal_thing = pyqtSignal()

    def long_running(self):
        print("Do the thing you need to do")
        print("You can pass full functions and their args if you set it up right")

my_thread = QThread()
worker = Worker()

# We're connecting things to the correct spots
worker.moveToThread(my_thread)
worker.signal_thing.connect(whatever_you_want)
my_thread.strted.connect(worker.long_running)

my_thread.start()

So you have a worker object that will actually run your code, you move that object to a thread (it'll now run in the thread loop, not the main event loop). You can not connect to the correct signals and then you start it.

I usually use QRunnables + QThreadPool, you can see a full-up guide for that here: https://www.pythonguis.com/tutorials/multithreading-pyqt-applications-qthreadpool/

[ionic nacelle]

the long running task is a method from another class, that shouldn't be an issue

?

[static cove]

So for that part, that's where I would use the approach in the pythonguis link, they have it setup so it can take in an arbitrary function and execute it

[ionic nacelle]

so should I use qrunnable or qobject @static cove

[static cove]

That's up to you. If you use QThread then you don't need QRunnable. Either way both solutions use QObject for the worker portion

[ionic nacelle]

signal_thing = pyqtSignal()

what does this do

its not recognizing it

[ionic nacelle]

https://paste.pythondiscord.com/cekowojute
I've done what you said but it's still not working @static cove

I need help with using Github, not sure where is appropriate to ask.

I'm included in a repo that is private and will be deleted soon. I want to essentially clone that repo into my own repo (including all the commits made) so I can include it on my Github page. I can't fork (i dont really understand that) and I'm not sure if branching is the way to go.

I've been advised that I want to pull the original repo, make a new repo, change the remote and then push the original repo into the new repo.

I can't pull the original repo, perhaps I'm doing it wrong but I just don't have the option to pull.

Any help is appreciated!

I am trying to make it so when I click the button

instead of on

[timid dust]

It'd help if you share the full error

It'd tell us which line this is on

In this case, Label.config is a method which operates on a label instance

(such as is_on_off_label)

Not the class itself

[eternal kestrel]

Hi, would it be possible to ask questions about tkinter here? I think I understood how to create buttons etc, but now I need to tell my GUI what motors are available. My motors are from another class. How can I feed them into a GUI? Via new input parameters?
I don't think my GUI should inherit anything from the motors, just use them and their functionalities.
Many thanks for your help.

[tight imp]

what is the best ui other the pyqt5

????

[eternal kestrel]

Maybe this tkinter oder a webinterface ?

[tight ice]

pyqt5 is the best for python

if you want good ui go to c++

or some other language like that

[tight imp]

ya but you need license for

it

I am considering pyside or kivy

[tight ice]

?

pyside2 is basically the same as pyqt5 but different licensing

Does anyone here know how to change the background colour of a video widget in PyQt5 to black instead of invisible? Thank you.

[tight ice]

i know nothing about video widgets but have you tried settings the stylesheet with the background colour being black?

[quartz dust]

okay so how exactly do I change the colour property. py app.setStyleSheet()

[tight ice]

it mimics css

https://doc.qt.io/qtforpython/overviews/stylesheet-examples.html

background-colour: black;

[quartz dust]

oh okay, so like this. py app.setStyleSheet(QVideoWidget { background-colour: black; })

Wait, it doesn't work.

Why is that.

Oh I fixed it, nvm

app.setStyleSheet("QVideoWidget { background-color: black; }")```

tysm!

PyQt6 if you're a beginner

but if you wan't next level customization you can go with pygame

i would personally go with pygame since it allows you to choose framerate(which is necessary to update the gui) you also get animations and much other options

Hello, hoping someone can help me with just conceptually thinking through what I'm trying to research.

Looking to create a UI that essentially takes in a dataframe with columnar color values, displays those values as a color map with column and row labels, and allows the user to interact/change the colors through a dropdown. Is this something that's worth checking out Pyautogui/tkinter for? I'm just trying to figure out exactly what it is I'm looking for

Heyas, anyone have knowledge about QT with python with there licences?
I know there are GPL and LGPL
But my Question is, hypothesis example: If i made and Windows Application with PySide ( because pyqt its such an money waste) (Its QT) and would sell it without giving away my Sourcode. What kind of licences i need? Or what should i do?

[mighty frigate]

@kindred mistcan't do that without paying a Qt license afaik

@kindred mistok so

LGPL/GPL : https://tldrlegal.com/license/gnu-lesser-general-public-license-v3-(lgpl-3)

so you actually can use it for a commercial software

[kindred mist]

This licences are realy weird to understand

^^

[mighty frigate]

but you need to disclose the source code

if you don't want to -> commercial licence

[kindred mist]

and QT commcercial = 300$ per Month

[mighty frigate]

in the Qt doc, it's pretty clear tbh

https://wiki.qt.io/Qt_for_Python

https://tldrlegal.com/license/gnu-lesser-general-public-license-v3-(lgpl-3)
https://tldrlegal.com/license/gnu-general-public-license-v2

@kindred mistQt is a major sets of libraries built over 2 decades. Why would you not pay the people who did it ?

[kindred mist]

Thats not the problem to pay for it, its the amount of price for it for an startup

its min 300$/Per Month

[mighty frigate]

you can contact them

or dev your app on the opensource licence and buy a license when you want to distribute your product

or there's also tons of other libs out there

[kindred mist]

My plan was - the Programm are free, only the support and custom changes are on price

But know, i thinking about to change the language to C#

[mighty frigate]

Qt isn't available in C# afaik

[kindred mist]

na but other GUI tools

[mighty frigate]

ah ok

[kindred mist]

like WPF

[mighty frigate]

ok well, hf gl with your startup

gotta get back to work

[kindred mist]

yeah, i still use Python for background work and use c# for the front end

i think thats the better solution

[mighty frigate]

I'll be honnest I don't really understand why you would use Python for a UI application

[kindred mist]

me too, was my first language, and my appliaction run now for 1 year in live in a test ^^

[mighty frigate]

but you can't really distribute it can you

[kindred mist]

so my coworkers use it everyday for free to test the internals.
But i will change that to C#. thats better 😄

[mighty frigate]

can't really distribute the scripts files

can compile in an exe files but with very poor performance

I genuinly don't understand why one would use python for a commercial UI app

[kindred mist]

ya, the perfoamcen is meh

[mighty frigate]

not the startup

the startup performance of a pyinstaller exe is really, really bad

especially with big libraries like Qt

[kindred mist]

but thats the point, and have to so say big thank you for the decision to push the project to c#.

Python was a easy start, and my fav language, but for Applications its not the best

[mighty frigate]

it's good for prototyping and testing

at least that's what I'm doing with it

but all our products are in C++

[kindred mist]

ya, i was thinking about to learn c++, but the syntax :D. And i think C# its a good alternativ

[mighty frigate]

I don't know much about C#, I guess if portability isn't a big concern for you it's fine

[kindred mist]

yeah a bit to learn, but its ok. Programming language are not that hard

the hardest part of the languages in c# and c++ are that inherited things

in python -> easy
C# -> what?
C++ -> &!"%§$

[mighty frigate]

inherited ? you mean OOP ?

[kindred mist]

ya

[mighty frigate]

C++ OOP is not much harder than in any language in my opinion

the real struggle - for me at least - comes with templates, concepts, and metaprogramming

[kindred mist]

public class Adult : Person i think such things are confusing, how is this in c++?

[mighty frigate]

in cpp

class Adult : public Person {

in python

it's really not that different

yess im heere!

[static cove]

hi! Okay, let me type this up

So, the trick with this is two things!
For you have your

for index in range(len(food)):
    radio_btn = RadioButton(...)

you want to replace value=x with value=index!
right now, value will be StringVar(), which makes it tricky to check against. If it changes to index, then the value will be "0", "1", "2", etc.

Then the second trick, the quotes around the numbers above is intentional. Turns out that tkinter will convert the value to a str for StringVar -_-.

So you have 2 options:

1. Change your if-statement checks to check for the string version of the numbers (i.e. if (x.get() == "0"):

2. Re-work your if-statements to look like the following:

def order():
    choice = int(x.get())
    if choice == 0:
        print("You have chosen cheese.")
    # etc

[static cove]

^ check above and lmk if anything isn't clear

[upbeat pendant]

will let you know ^-^

[upbeat pendant]

im really sorry , im getting error(PYVARO) for the 2nd one and for the first one its printing only curry

[static cove]

can you share your current code?

ignore the comments , coz im a beginner and want to understand each line of code

[static cove]

ah! when you create your radio_button, change value=x to value=index

[upbeat pendant]

wow , its working!!!1 , thanks for spending your time on me , means alot!!

do you mind ,if i ask more query

[static cove]

go for it~ happy to help

[upbeat pendant]

so my current output looks like this , and i want to add scroll bar coz i need to choose the other two option which is hidden .... the size of the images are pretty big (i can still make it small and get the other two options to be visible) ,but i want to create a scroll bar as it'll be helpful in future!

[static cove]

So, I would probably try to re-size the images to all be the same size, that would be the first thing I do.

But also, you can totally add a scrollbar. This is a good site to use as a reference, check it out: https://www.pythontutorial.net/tkinter/tkinter-scrollbar/

@static cove so i kinda messed up pretty bad

🥲

i didnt understand what each line of code was doing (scroll bar part)

[static cove]

is that indentation correct?

[upbeat pendant]

i think so , there was no error , only a blank window popped with nothing in it

[static cove]

so, I don't think your indentation is correct. It won't error, but it's not correct. You have most of your stuff under the menu() function, including where you actually call menu(). So, take a look again and see what actually needs to be indented under that function.

Also! When you see in the tutorial they have root = Tk(), you don't need that. You want to use your existing window = Tk() and apply those concepts to that

[upbeat pendant]

i tried pretty much everything in my knowledge to fix it , i cant do it 😢 ,

im checking yt now for more light on this topic

[midnight pecan]

how difficult is to create a nice-to-see interactive UI

[digital rose]

Hi guys, I'm an javascript developer and I made a game that needs you to click on the stop button when the player circle collides with a red one. I'm trying to learn python and the question is, which library would be the best for tracking the collision moment and hits the stop button? ;D

[mighty rock]

How did you do it in JavaScript? You can always check whether the bounding x position values of each shape ever intersect

[digital rose]

but i dont want to make it inside a browser, more likely to "inject" python into the window and track this green circle

[mighty rock]

Have you heard of PyScript?

[digital rose]

yep

[jovial verge]

do do yo know way to get input of mouse wheel?

it's rare applications and can't find answer on internet

[mighty rock]

Well, then, you won't need anything other than PyScript, I think. I don't know how PyScript interacts with the DOM, though

[mighty rock]

I think you can only get the amount of displacement from rolling (delta)

[jovial verge]

so only speed?

[mighty rock]

As fast as a Python loop can be, I guess

Maybe you can use a module that queues several inputs in one call so it seems more responsive

[jovial verge]

I need to know how far user zoomed out since beggining

[mighty rock]

You will have to keep track then

Since a beginning value

Whatever it may mean to you

[midnight pecan]

how difficult is to create a nice-to-see interactive UI

[tight ice]

not overly difficult

[jovial verge]

how percise it it?

[tight ice]

for example, if you used qt you can render ui files with stylesheets that mimic css, and there are also designers such as the qt designer which is pretty easy to use

[midnight pecan]

where can I see examples of nice UI's ?

and what packages will I be using?

[mighty rock]

There is no reason it will be imprecise. It's measured in screen pixels, probably.

[tight ice]

!pypi pyqt5

[proven basin]

PyQt5 v5.15.7

Python bindings for the Qt cross platform application toolkit

[tight ice]

this most likely

unless you want a different license in which case its

!pypi pyside2

[proven basin]

PySide2 v5.15.2.1

Python bindings for the Qt cross-platform application and UI framework

[mighty rock]

They want to see examples of nice user interfaces

[tight ice]

you would probably use the qt designer to generate ui files

[tight ice]

are those apps not examples?

[mighty rock]

I was just saying it because you started giving PyPi pages

[tight ice]

because they said

What packages will I be using?

[mighty rock]

Well, you can arguably create nicely looking GUIs with tkinter

[tight ice]

I would disagree strongly with this

[midnight pecan]

what do you mean by license?

I wont crat games it'll be a simple app tbh

not EXTREMELY simple, but something someone with decent experience can create

[tight ice]

I can't remember exactly, but there are some license catches

[tight ice]

it's your choice, tkinter is nice and beginner friendly but qt is more professional looking with a designer and styling

[midnight pecan]

something like this? https://docs.cidaas.com/assets/App Settings Overviewss.png

[tight ice]

yeah you would probably not want tkinter for that

[midnight pecan]

better to use qt for this?

okay 🙂

so qt and what else?

[tight ice]

you could also use eelinstead of qt

!pypi eel

[proven basin]

Eel v0.14.0

For little HTML GUI applications, with easy Python/JS interop

[midnight pecan]

what would you use? 🤔

note that I only used python, I dont know any js for example

[tight ice]

probably qt, primarily because i have more experience with it

[midnight pecan]

will I need to learn new languages to create something like this?

[tight ice]

probably a bit of js and a decent amount of css styling

[midnight pecan]

I see... but will you limit yourself because you resigned to eel?

[midnight pecan]

rip

css ok, not difficult as far as I'm concerned, but js is a complete different language

css is styling only

[tight ice]

js is pretty similiar and easy to start with

[tight ice]

i don't understand

if i were to make a project, i would go with whatever is best for the project

and discard experience to a certain extent

!pypi flexx

[proven basin]

flexx v0.8.4

Write desktop and web apps in pure Python.

[tight ice]

there is also this :D

[midnight pecan]

for example if I use tkinter I wont be able to code something like this. tkinter would be limiting me, if you use qt will that limit you?

[midnight pecan]

so umm for this you would recommend qt, css and js?

[tight ice]

probably not, qt is quite extensive so would probably do the job

[midnight pecan]

I'll ask a friend to do the js part for me lmao

[midnight pecan]

okay

[tight ice]

no, qt is completely seperate to css and js

there are 2 different packages

eel

and

pyqt5

eel uses css and js

pyqt5 uses ui

ill recommend pyqt5

[mighty rock]

I don't see a reason why you couldn't reproduce this in tkinter. Well, you will probably not have shadows

[tight ice]

what styling methods does tkinter implement

[midnight pecan]

oh I'd like to use python the most and avoid using other languages, but if using other languages is compulsory, then well I'll learn it

[tight ice]

then you'd use qt

[mighty rock]

Themes.

[midnight pecan]

pyqt5, you mean?

[mighty rock]

A Style object in tkinter.ttk for creating styles for (tkinter.ttk) widgets (there are namespaces and stuff so it's not like you have to use a style for an entire widget type)

[tight ice]

yes

[midnight pecan]

ok 🙂

and what about pyqt6?

[tight ice]

there arent many major differences but from what i can tell pyqt5 is used more

[midnight pecan]

okay 🙂

tysm

[tight ice]

np

[ionic nacelle]

how would I make the brown background touch the corners of the application. PyQt5

im sorry to come out of nowhere , my question is , is html more convenient than using the module "tkinter" ?

[modern girder]

well html is a mark-up language for websites, it is very different in use-cases and technology with the Python package tkinter for making desktop GUI's.

[upbeat pendant]

ohhh , ic

so , html = websites

and

tkinter for widgets?

[modern girder]

not quite, you use html to write the structure of a website, while widgets are a part of tkinter.
It's very theoretical like this, follow a tutorial or two and it will make more sense

[eternal kestrel]

Hi all,
I was told I should ask such questions here.
I got a basic gui with tkinter
I have a ttk.combobox. I can select the current value with ttk.combobox.get().
Now, I bound the selectioin to a method. But I want to pass the value of the selection to a new method in my controller.
self.view.sidepanel.motor_sel_combo.bind("<<ComboboxSelected>>", partial(self.motor_selection, self.view.sidepanel.motor_sel_combo.get()) )
It does not work. I get an empty string back.
I would like to pass this argument through to a method in my controller class.

 def motor_selection(self,event, mot_selected):
        print(f'{mot_selected} is selected!')
 ## Bound method:
self.view.sidepanel.motor_sel_combo.bind("<<ComboboxSelected>>", partial(self.motor_selection,  self.view.sidepanel.motor_sel_combo.get()) )

self.view.sidepanel.motor_sel_combo.get() holds the value of the combobox.

If I would do:

self.view.sidepanel.motor_sel_combo.bind("<<ComboboxSelected>>", self.motor_selection)
 def motor_selection(self,event):
        mot_selected= self.view.sidepanel.motor_sel_combo.get()
        print(f'{mot_selected} is selected!')

it works, but this is not a good style I think. Using partial from functools seems to be an option.
I am scared of lambda functions, but I saw on stackoverflow some examples with partial from functools.

[digital rose]

what do you think about this UI which improvements it needs

[eternal kestrel]

Dear all, would somebody mind to explain to me tkinter bind https://docs.python.org/3/library/tkinter.html?highlight=bind#bindings-and-events-1 It does not show an example how to pass values to it

[modern girder]

you're trying to set a grid on the string 'white', that's not possible
maybe the . was meant as a , ?

[digital rose]

nope

i tried moving the grid() to the front but it still didnt work

i will tinker around with it until i find a fix

[modern girder]

to the front where ? if you put it after 'My Program' you will get the same error

[digital rose]

ok then.

so

i cant use the grid

because i need it

for my tk window

the white is a string

so i cant do that

hmmm

ok

so i fixed that

but now im getting a error

start_label.pack()

Hi everybody. I am currently working with tkinter. I understand I cannot mix pack and grid for widgets when the share the same master or are attached to the same master. But what happens when I make a new class and hand over the ttk.Frame with widget on it using pack? Still bound to pack for new widget?

[wanton pulsar]

i guess

try to add it to one mainloop

like root.mainloop()

every class pack with that root mainloop

then it will maybe work

i am not sure

if it doesn't work i am so sorry

[eternal kestrel]

Did somebody use for tkinter in the past maybe the showwarning window? A window appears, nice. But when I close it, I wish the current function is left. Anybody know what to google for, please? I would like to leave the current workflow that was before executed.

[indigo crane]

question needs elaboration

[indigo crane]

you cannot use both pack and grid on widgets of the same master
but you can if the widgets have different masters, depends on other child widgets on respective master

[eternal kestrel]

Thank you. Then I need to clarify what is a master. Can you help me to understand.

[indigo crane]

master is not a keyword, just a metasyntactic variable, its the parent window the widget is sitting under, you pass it as a parameter to the widget

[eternal kestrel]

I have a self.master=tk.Tk(). On it is a set.frame=tk.Frame(self.master). My other parts of my GUI are classes. I hand over for example
self.sidepanel = SidePanel(self._master)
The SidePanel Class gets then this self._master

[indigo crane]

the sidepanel widget now have self._master as its parent

[eternal kestrel]

But then does not everything sits under the the same frame?

And if I use on the parent already pack, can the child use grid ?

I mean all widgets on Sidepanel, doe they have to use now pack as well, please?

[indigo crane]

import tkinter as tk

root = tk.Tk()

frame1 = tk.Frame(root)
frame1.pack()
frame2 = tk.Frame(root)
frame2.pack()

frame3 = tk.Frame(frame1)
frame3.grid()
frame4 = tk.Frame(frame1)
frame4.grid()

see what i did there, if a child of a parent uses pack manager, all other child widgets are supposed to use pack too

[indigo crane]

nope

[indigo crane]

yes

[eternal kestrel]

Great news. Then I need to understand why my entry boxes are not showing up on the sidepanel. One moment please

[indigo crane]

probably forgot to pack/grid

[eternal kestrel]

But before frame3 is a child of parent frame1, pelase?

[eternal kestrel]

No, I don;t think so.

[indigo crane]

oh?

[eternal kestrel]

class MotorPanel():
    #You cannot use both pack and grid on widgets that have the same master.
    def __init__(self, root, model):
        self.frame4=tk.Frame(root)
        entries = []
        for column in range(3):
            entry = ttk.Entry(self.frame4, font=('Calibri', 7))
            entry.grid(row=0, column=column, sticky="nswe")
            entries.append(entry)

[eternal kestrel]

I beg your pardon? Was I wrong with my statement? I wanted to check if I got the child/parent concept

[indigo crane]

you didnt pack/grid self.frame4

[eternal kestrel]

This code above does not show up for some reason.

[indigo crane]

so its child widgets are not visible too

[eternal kestrel]

Oh, I have to pack a frame? not with grid? I am confused

😦

[indigo crane]

no

you can pack/grid

[eternal kestrel]

But now I need to say self.frame4.grid() ?

[indigo crane]

class MotorPanel():
    #You cannot use both pack and grid on widgets that have the same master.
    def __init__(self, root, model):
        self.frame4=tk.Frame(root)
        self.frame4.pack() # or grid()
        entries = []
        for column in range(3):
            entry = ttk.Entry(self.frame4, font=('Calibri', 7))
            entry.grid(row=0, column=column, sticky="nswe")
            entries.append(entry)

[eternal kestrel]

I got also a weired message when I tried to setup the columns, and rows.

@indigo crane But when I now pack the frame4 with pack, and use on the ttk.Entry widgets grid, why does it work please?

Is this not the mix ?

Wow. I can see them, but the are at the bottom of the panel. Not at the top.

If I use pack() on frame4, all childs need to use pack as well, please?

[indigo crane]

• frame4 have root as its parent -- every child of root is using pack, so frame4 can be packed
• entries created have frame4 as their parent -- every child of frame4 is using grid, so entry can be grid'ed

[indigo crane]

no

[eternal kestrel]

I get now TclError: cannot use geometry manager grid inside .!frame2 which already has slaves managed by pack
with :

class MotorPanel():
    #You cannot use both pack and grid on widgets that have the same master.
    def __init__(self, root, model):

        entries = []
        for column in range(3):
            entry = ttk.Entry(self.frame4, font=('Calibri', 7))
            entry.grid(row=0, column=column, sticky="nswe")
            entries.append(entry)

with .pack it works. It seems frame4 is allowed to have pack, but the ttk.Entry widgets can use grid().

[indigo crane]

the manager used for parent doesnt affect the manager to be used for child

not related

[eternal kestrel]

Thank you. I have to use for all childs of root pack, because at the start I used the pack method on root?

[indigo crane]

root is tk.Tk i assume, so you dont have to pack/grid it

remember this, if you packed a child widget, all other child widgets of that master needs to be packed
BUT that doesnt mean you will have to pack the child widgets of a child here

[eternal kestrel]

One moment, roughly like this:

class MainWindow()
  self._master = tk.Tk()
  self._frame = tk.Frame(self._master)
  self.sidepanel = SidePanel(self._master)

In SidePanel class:

class SidePanel():
    def __init__(self, root):
        self._model=model
        self._frame2 = tk.Frame(root)
        self._frame2.pack(side=tk.LEFT, fill=tk.BOTH, expand=1)
        self.motorpanel= MotorPanel(self._frame2)

class MotorPanel():
    #You cannot use both pack and grid on widgets that have the same master.
    def __init__(self, root, model):
        self.frame4=tk.Frame(root)
        self.frame4.grid() # or grid() or pack()  #Error was: forgot to pack() frame4. so its child widgets are not visible too
        entries = []
        for column in range(3):
            entry = ttk.Entry(self.frame4, font=('Calibri', 7))
            entry.grid(row=0, column=column, sticky="nswe")
            entries.append(entry)

"the manager used for parent doesnt affect the manager to be used for child" - could we go through this again please?

remember this, if you packed a child widget, all other child widgets of that master needs to be packed
Nope. I am sorry. When is a widget a parent, when a parent?

[indigo crane]

SidePanel._frame2 is a child of MainWindow._master
MotorPanel.frame4 is a child of MainWindow._master too

both have same parent, both needs to use either pack or grid

[eternal kestrel]

But we said that other widets that access frame4, can use grid.

Because the manager of this child is not affected by the manager of the parent?

[eternal kestrel]

And the manager is determined by the first time I apply grid() or pack() to the this parent.

I will try out to arrange the ttk.Entries in column, row.
I did not understand the what is here the container please

container.columnconfigure(index, weight)
container.rowconfigure(index, weight)

@indigo crane Can I ask you please something else. I have so far my methods that operate on my GUI under the class MainWindow(). I understood in Python methods kept private with one underscore. Can I still have methods for example under Sidepanel and access them from somewhere else, please?

My Controller only calls the MainWindow but then all SidePanel is also in MainWindow

[eternal kestrel]

You asked me for elboration. If some checkboxes are not activated, I can pop up a new window with showwarningmessage . A new window pop ups, the user closes it. But this appears in a workflow, that was started by a button action. Now I want to leave this workflow basically and not to continue, when the users closes the popup window.

[indigo crane]

what do you mean by a workflow? a thread?

[eternal kestrel]

Do we call this a thread that follows after an event is started through a button action?

[indigo crane]

these are to give them weights, if two rows have equal weights, they will divide the space 1:1

the more weight, the more space they will take

[eternal kestrel]

I have a button to which a function is bound. I think this is the callback. Within the callback is a process started, just a procedure. If other items on my GUI are not selected, the process won't work. So I wanted to check what is selected by the user. If something is missing, the callback should stop and not continue.

[eternal kestrel]

Thank you. And what is the container, please? The reference to the ttk.Entry?

[indigo crane]

iterate and check all the checkboxes, and if any are not selected, return

[eternal kestrel]

Do I really have to iterate? I have all checkbox-Variables in a dict, I can acess. If all values are 0, I know the user does not have selected any. I want to leave then the current method, but I don't know how. Is there a exit() command?

||if not self.view.get_motor_selection():
            self.view.no_motor_selected()
        else:
            mot_selected=self.view.get_motor_selection()
            print(f"Selected motor for scan is {mot_selected}.")||

I don't know what to put in the first part of the if-statement after self.view.no_motor_selected() to exit.

[indigo crane]

return

[eternal kestrel]

Oh, sorry. I did really not know. But I guess it makes sense as it is a normal method. 🥰

[eternal kestrel]

@indigo crane I am just seeing that on ttk.Entry are a lot of methods available? Do you know by chance a good docu, please?

[eternal kestrel]

Hi, I found this on StackOverflow as an example.
https://stackoverflow.com/questions/33646605/how-to-access-variables-from-different-classes-in-tkinter
Is the StartApp what they call controller, please?

[soft patio]

Is it possible to state which UI frameworks should NOT be used? I'm a little overwhelmed by the options, just started python (though thousands of hours in other languages), and I just need a stupidly simple app with like drop downs, text fields, ability to access an online database and be made stupid simple for someone with no code background to use

The worst and best part about python is having so many different options and not knowing what is the best for a project lol

[eternal kestrel]

I am also a newbie with Python GUI. There is a podcast episode about GUI in talk python to me. It is mostly about wxPython

[gritty apex]

Use tkinter, comes built in, you're probably making a desktop app so Tkinter comes built in, makes it feel native, but it isn't
Use the themed widgets (ttk), maybe this for a Widows 11 feel https://github.com/rdbende/Sun-Valley-ttk-theme
Or any other theme from here https://rdbende.github.io/tkinter-docs/resources/list-of-ttk-themes.html

I've been investigating this all day and came to the conclusion that If I make a python UI is bc I want to make some desktop utility, so it's either that or wxPython, the later being harder to use and the only solution with real native widgets, if you use wx with python 3.10 use the latest build as shown here https://www.daniweb.com/programming/threads/537799/python-3-10-and-wxpython-compatibility

[eternal kestrel]

@gritty apex https://www.pythonguis.com/faq/which-python-gui-library/

[gritty apex]

The ones using Qt are quite overkill, Davinci Resolve uses Qt for example, the rest have more particular use cases, like kivy being more focused on android

[eternal kestrel]

Am I correct, that if I have a ttk.Entry, it is mostly important to track the textvariable because it contains the input value? Opposite I care less to deal with the variable name of ttk.Entry.

handle=ttk.Entry(textvariable=var1)

So I am mostly interested in var1 as tk.Variable. And I care less about the handle. Is this correct?

I went with tkinter because it was pure python and it seemed doable. People seem to be in favor with flask

I had a quick glance at wxPython. The principle seemed very similar as in tkinter.

There are also Galaxyservers as GUI.s

[gritty apex]

If you're making something more complex might be better to keep track of that, indeed

[eternal kestrel]

Okay. And I realised I have for example two options to access the value. Either with handle.get() or var1.get()

[gritty apex]

Wish all this was as easy as with js frameworks

[eternal kestrel]

Is there any preference?

I have no experience with js.frameworks.

I started to save all textvariables/variables of the widgets in dicts.

[gritty apex]

idk, I've been using this for a couple of days, but I guess wathever you feel keeps you more organized

[eternal kestrel]

What does idk mean please?

[gritty apex]

IDK is short for I don't know

[eternal kestrel]

@gritty apex But you agree, the results should be the same value?

[gritty apex]

Yeah, they're binded after all. You might be using that var1 in a label or another input (would be weird having two textboxs for the same things, but that's the idea)

[eternal kestrel]

Nice. I think I understand it better now.

[gritty apex]

yeah, maybe you're more familiar with html and css, there you can separate the inputs (in html) from the colors and layout (in css), althought in html you're already making some layout decisions by the ordering of the widgets

[eternal kestrel]

I have not tried it, but could one also access the textvariable via handle["textvariable"]

[gritty apex]

Idk, but I've been looking at implementing hover styles and they used that kind of syntax for the styles (second answer)
```` e.widget['background'] = 'green'```
https://stackoverflow.com/questions/49888623/tkinter-hovering-over-button-color-change

I've been trying to reset an input (after clicking a button) and didn't find a way to

From where can I learn tkinter? (except Youtube)

[gritty apex]

This lookied quite nice, compared to the terrible looking official docs https://www.pythontutorial.net/tkinter/tkinter-hello-world/

Also here: https://pythonguides.com/category/python-tutorials/python-tkinter/
https://rdbende.github.io/thttps://rdbende.github.io/
https://tkdocs.com/

[eternal kestrel]

Yes, that is what I noticed. I will try it ould in the code.

That is the official doc? Ui, I don't like it

[digital rose]

tyty

[eternal kestrel]

I liked this one https://anzeljg.github.io/rin2/book2/2405/docs/tkinter/index.html

[gritty apex]

Another ugly one that looks streight out of the 90s 😆
might be good, idk

[eternal kestrel]

After seeing this one, I realised how good numpy doc is

and I though numpy is tricky, no this one is more challenging

I mean tkinter

[soft patio]

Oh wow nice! Lots of good resources from youu

If tkinter is so badly documented then why not something like pysimplegui? Eh they all seem fairly easy to work with, so I can play with them all

And see which ones I hate as I try to implement things

[gritty apex]

pySimpleGUI only has one look, and I've seen it used all over that program that adds shaders to games and random openGL demos

Tkinter despite being simple, is built in, which is a nice pro, feels close enough to native and has a fair amount of tutorials and a very good amount of themes

[soft patio]

I'm gonna need to interface with a cloud based database so idk... Seems like Qt stuff if better

[soft patio]

Why is built in such a pro? I'm going to need other libraries anyway :)

[gritty apex]

The nice thing about Qt is it has good drag and drop editors

[soft patio]

That and maybe being able to view the database in-app is really nice

[gritty apex]

Well, if you want someone else to use a gui for simple stuff while only using other stuff in the std lib is great

[soft patio]

My coworker wants a web based app, but idfk how to make it secure... And that scares me

[gritty apex]

Something like a file renamer or some calculator, etc

[soft patio]

The front-end is simple but the backend is not in my case

[gritty apex]

Yeah, in js, your api keys are never 100% secure, you can use .env filebut even then, you're better providing data directly from the backend

[soft patio]

99% sure but asking just in case. I could access a relational database on the cloud or (sadly atm) an excel doc on the cloud yes?

That's just backend stuff that you could do in normal python

[gritty apex]

I'm just into front-end, I've been investigating into python GUIs a couple days for making some utility for myself (I did a while back as well, so I'm more like refreshing things)

[soft patio]

Yeah your help is appreciated!

Any reason Flask hasn't entered the discussion?

[gritty apex]

I know 0 about backend, I only know to consume APIs, that's it hahah

[gritty apex]

I was asking in this web dev server yerterday about what to pick, they liked flask for quick propotypes, but hated Django, they didn't use any node and told me to go with Go since you can pretty much use the std lib to do everything https://discord.gg/wD8h4fNn

Any python docs, and specially the GUI docs are so ugly, compared to any js framework or even the smallest library, you can tell js/css frameworks are made for people making GUIs on the web, well, the docs themselves have to be pretty if they're indeed made by a front-end dev 😆

[soft patio]

Oh shit Qt stuff, at lest 6, is 360 a month for commercial

[soft patio]

Very nice ty

[soft patio]

Node as in node.js? I'd rather stay in python if possible lol

[gritty apex]

Yeah, that's the only problem with it xd

[soft patio]

Idk... Maybe the tech support would be worth it. I think Flask is great eniugh and I found this https://www.fullstackpython.com/flask.html

Which links to

[gritty apex]

yeah, node.js, I think node might be good since is js as in the front, and frameworks might take ideas from the front-end frameworks, either that, go, or flask would be my next thing to learn hahha

Oh my... I hate those buzz terms like I18n A11y and so

[soft patio]

I doubt adding JS to learn would make things EASIER. God thereshould be a limit on the number of type of libraries. They should have to fight to the death after, say, three

[soft patio]

Lol idk what they are. I just like the first few entries is all

[gritty apex]

A11y is Accesibility, I18n is internacionalization (wathever you spell it)

[soft patio]

I'm a godamn color scientist / R&D programmer, not a true programmer and especially not app development

Interesting, sent you a friend reuest

Anyway, it's late and despite the hot weather, I'm getting sleepy now, see ya

i have a serious doubt. Is it possible to make a widget in windows using python? is there any module for that ?

[modern girder]

sure tkinter and PyQT5 for example

[eternal kestrel]

Hi everybody. When I validate my entry for a ttk.Entry I can get the Widget name back. It shows like !frame!frame2!entry , can I access this somehow else, please? I don't know what to search for

[distant swift]

i have made apps with it. but i don't know how to make widgets can you send me a tutorial

[modern girder]

lmgtfy 🙂 https://www.youtube.com/watch?v=3UVjr8Onll8

[distant swift]

what i mean by widgets is something like a clock in the home screen of a phone and speech recognition widget and xbox game bar widgets etc

[mighty rock]

Those are windows without the menu

They are possible to create in tkinter, as far as I know, by doing Tk/Toplevel.overrideredirect(True)

[indigo crane]

https://anzeljg.github.io/rin2/book2/2405/docs/tkinter/ttk-Entry.html

[gritty apex]

I can't believe not even the official docs have explicitely a page for the entry widget, here's a list as well, but apparently, just for the non ttk version https://www.tutorialspoint.com/python/tk_entry.htm

[eternal kestrel]

Yes @indigo crane

I found this too

I think now I reached my limits

Could I ask for help please>

My simulatioin GUI is working

But when I do a scan ( a motor moves per step via a scan_iter+ yield) and I want to update any other field at the same time, tkinter stops.

I tried to build in the scan command, but it has a decorator on the function definition, I don't get this into my class

Is this where I have to look into threading, please?

or is there an easy way to understand how to get this dectorator and the class it originates from into my own class, please?

@gritty apex there is also ttk.LabelEntry

[azure talon]

I'm messing with tkinter and when I make a button to add another text box to the screen, after a few it starts not rendering the first couple. I can still tab back up to them and they show. Should I put an extra loop to something so it renders everything?
Or something recommendations to something other then tkinter for surface level data entry?

[gritty apex]

maybe using themed ttk widgets or the non themed ones could help?

[azure talon]

maybe

[gritty apex]

I'm using Tkinter and calling functions from both command and bind. To don't get errors I have to define the functions with one input event parameter, then on the "command" attribute use a lambda and call the function with a dummy 'e' string parameter, it feels super hacky, but I don't know about a better option...

[azure talon]

Yea I'm not having issues calling the functions or anything. Just when it loads in another text box, visually some of the others disappear. If I tab back to where they should be they are still there and then show up. It's strange.

[cobalt oxide]

pysimplegui is also... Um hard to read if you need to view its code

Like it's 25,000 lines in one single file that makes up the module

[gritty apex]

Might be some tkinter bug, are you using object oriented or straight functions? Proably you should avoid deeply nesting widgets, idk really thought, maybe something easy that doesn't use Tkinter under the hood, but the easiest might be kivy and the html/css based ones before going fully into the big Qt ones, some wxPython wrapper like wax might be other option

[gritty apex]

The docs are the same, a very long single page, or very few single pages 😆

pysimplegui also seems bloated with so many ugly themes, also the autocomplete takes a while to load, I even have to restart vscode

[cobalt oxide]

You should see the comment at the top of pysimplegui which is a lengthy explanation and apology for the code being ugly

[gritty apex]

lmao, they also say it creates very pretty UIs when is just legacy W95 looking tkinter, I know it has it's place for people that want a gui with the least possible code, but... 🙄

[cobalt oxide]

The interesting thing about tkinter is that tcl/tk was written in the same year as perl. I just find it amusing that it has found new life.

[gritty apex]

Python and Perl also came around in the 80s right? Also the "cannonical" tcl docs are terrible, super long lines, serif font, no spacing, absolute claustrofobic

[cobalt oxide]

Perl and TCL were '84

Not sure about python

@gritty apex I noticed you mentioned kivvy but left out beeware. Any reason?

I mean I know beeware is alpha software.. but it has a lot of promise for native mobile widgets

[cobalt oxide]

Python 1991

[gritty apex]

91'? Almost 😛
I hadn't seen beeware, will take a look

[cobalt oxide]

Beeware.org I have an app that I wrote on my phone using beeware at present

[gritty apex]

Just added it, the webpage is pretty good looking

This past week I've been very active here, cause I've been taking a break from front-end, I wanted too look at how to make native android apps, but thought about making UIs in python since I used tkinter before...

Idk why but even the gif branch of this tkinter theme is slow, and that's one of the most slick looking themes https://github.com/rdbende/Sun-Valley-ttk-theme

[cobalt oxide]

One of the interesting things about beeware is anaconda are funding them now

About wxPython

Is there any major different between a toolbar and a menu bar?

[summer vigil]

me when I get a "No module named 'sv_ttk'" Error

[gritty apex]

It's not a default theme, you have to install it first with pip

[summer vigil]

I did

[summer vigil]

Used cmd prompt but no go B(

[gritty apex]

I only needed to do this

import sv_ttk
# right after window config
sv_ttk.set_theme('light')

[gritty apex]

As I user I would say toolbar is for buttons and tools, as the name impilies, and menu bar, should add a menu on mac, so is more about text menu entries and dropdowns...

[snow talon]

Thanks for the descriptions, I have a couple of little comments, that hopefully can help to improve them further:

• Maybe 'Toga' (the UI library from Beeware) needs it's own section, instead of only being a side comment from Kivy (which is unrelated).
• Also, Beeware is not founded by Anaconda (maybe you meant 'funded' like support money), it's currently partially 'funded' by them, because they hired the main developer and 'founder'.
• You mention 'look native' and 'native'. I guess you can be explicit with the 'native widgets' -> 'widgets written purely in python', and 'look native' -> 'look native (related to your OS style)'

RE pySide/pyQT:

• The capitalization seems a bit odd, It should be 'PySide' and 'PyQt'
• It's possible to have commercial applications if you follows LGPLv3, without paying for a license. Maybe it's worth mentioning the license of the modules, with a link to the descriptions, so folks can read the differences.
• what's 'ui builder' ? you mean Qt Designer?
• and I think there is a misconception regarding the term 'compilation' in case it's that, it's just a conversion from XML -> Python, no compilation involved.
• 'hard to use', I understand that depending on the people confronting the different modules the experience is different, but I'm not sure if it's good for a general description to give our opinions, rather than being explicit on "why it's hard for you". Maybe you were referring about some details? maybe something like "having too many classes might be complicated" or "due to the many modules, it might be confusing", etc

[eager viper]

Thanks!

Follow up question

Is it possible to customize a window's top bar? In google chrome for example, the top bar plays host to tabs in addition to the close+minimize+maximize buttons

Thanks , I've changed it a bit, now I need two messagges, so second part now

Tkinter: Built in, easy, windows, linux and Mac, themeable (using ttk widgets), can pass as native except on linux(user themes), easiest to use after pysimplegui, if you're used to front-end work (html and css) unnoficial documentation seems ok-ish but is actually quite nice compared to other python GUIs. The only good designer with all options is pygubu. Can be made prettier with little code changes using CustomTkinter by @\tttx3
Some good looking docs:
https://tkdocs.com/
https://www.pythontutorial.net/tkinter/
A more complete one:
https://anzeljg.github.io/rin2/book2/2405/docs/tkinter/index.html
The best UI designer:
https://github.com/alejandroautalan/pygubu-designer

PySimpleGUI: Easiest to use trading not being not very configurable (use it only if you don't want to mess with positioning), bad looking: wrapper around tkinter (mostly using legacy tk widgets) and plan for other libraries like Qt. All the code is in a single module, so the source code is hard to read and autocomplete takes a while.
https://www.pysimplegui.org/en/latest/

PyQt/PySide: Each one uses a different license, so if you want to use it commercially, I recommend reading this https://embeddeduse.com/2021/04/18/using-qt-5-15-and-qt-6-under-lgplv3/
if you use ui builder like Qt Designer you need to convert to python, which is extra steps and might be more involved, pretty good looking, performant, looks native to the platform, but being a bigger library can be harder to use.
https://www.qt.io/qt-for-python
https://riverbankcomputing.com/software/pyqt/intro

wxPython: Actual native desktop widgets, harder to use, but lots of official examples. Other native libraries include pyforms or wax, the later being a high level wraper over this library
https://www.wxpython.org/
There's a very nice UI builder producing quite clean code called wxFormBuilder, here you can check some others
https://www.tutorialspoint.com/wxpython/wxpython_gui_builder_tools.htm

[gritty apex]

pySimpleGUI can color it, but moving it becomes glitchy, that's as far as I know

[eager viper]

In theory, I don't even need to use wxPython

I just need something I can embed a cefPython browser into

For all its faults, wx is a B E A S T

[gritty apex]

Trying to apply some web design concepts like containers and columns, very minimal but focusing on small details like padding and margins (Tkinter uses the pady/padx property inside pack method as margins, instead of the same properties in the widget). Used ttkbootstrap https://ttkbootstrap.readthedocs.io/en/latest/

[gritty apex]

the only thing I miss having negative padding to the two column layout was aligned more easily

[summer vigil]

uhhh

[grizzled creek]

that's pretty

[lofty pond]

Also dearpygui is also a great gui library with more complex widgets

[indigo crane]

yep python docs dont cover it, but ttk widgets may be there
i just use https://anzeljg.github.io/rin2/book2/2405/docs/tkinter/index.html for all cases

Hi all, I have a tkinter Text widget and a scrollbar (to scroll the text vertically). But when there is a lot of text (thousands of bytes) it becomes very slow and the program can get stuck. Any idea?

Never mind, I found this -> https://stackoverflow.com/questions/66613428/tkinter-text-scroll-lag-issue which should solve it (hopefully)

[gritty apex]

Do you know any website or video that could teach me how to build something like this?
@midnight pecan

There's a tkinter designer which can translate figma files, but if you want lots of animations and screens might not scale well

[midnight pecan]

not so many animations tbh, but yes lots of screens prolly

[gritty apex]

not so many animations tbh, but yes lots of screens prolly
@midnight pecan Maybe the html/css based tools night be a good option, you have lots of tutorials for web design

[midnight pecan]

I got told this can be done in qt with no problem

but tbh I dont know how to do it, obviously I dont cause I'm new to this but I've been through a couple of tutorials and this isnt intuitive at all

@midnight pecan I saw this discord clone recently https://youtu.be/3CbN21f_sD0

How can I get the HWND of a QMainWindow in PyQT6? I'm trying to make a win32 API call to give myself a dark taskbar, but I can't seem to figure out how to get these two different parts to "talk to" each other.

I believe the .winId() and/or .effectiveWinId() methods are somewhat related here, but I'm clueless as to how I can turn that into something I can pass along to ctypes.windll.user32.GetParent.

(or or is this a question better suited for #c-extensions?)

Update: Issue resolved! For anyone who may have this issue in future, user32.GetParent isn't needed at all, unlike with tkinter - just int(window.winId()) got me the HWND.

[crimson latch]

is it possible to combine tkinter and imgui?

[midnight pecan]

whata better, pyside or pyqt

[cobalt idol]

I think pyqt5 is better

[gritty apex]

Now I wanna know how do you exactly do it on tkinter to change the taskbar what module do I need for that "user32.GetParent"

[mighty rock]

You can get a window's HWND in tkinter using the winfo_id attribute

[mighty rock]

from ctypes import windll
user32 = windll.user32

or

from ctypes import WinDLL
user32 = WinDLL("user32")

(Windows only obviously)

[safe urchin]

Is there some way with PyQT5 I can create a window, without actually displaying it on the screen? I need the window to be instantiated so I can get its HWND, but I also don't want to render it immediately, as there is an ugly white flash as I switch over to dark mode.

[safe urchin]

Also, what is the best way to make a query to a REST API, and display the results in the GUI? I'm not sure whether to use some built-in PyQT functionality, just regular requests, or some asyncio aiohttp stuff

[rocky dragon]

qt has network stuff through QtNetwork but it's a bit of a pita with all the callbacks

[midnight pecan]

tysm!

[safe urchin]

Would you recommend using aiohttp instead of it then?

I've been really down on my luck trying to find any information online on PyQT stuff, and it looks like the type stubs are all wrong as well, which isn't helping at all

from what I have gathered though, it seems like it doesn't really play nice with external requests libraries, because they're either blocking or they require hacky event loop stuff

[eager beacon]

There is a ton of PyQt information out there. What type of things are you looking for?

As far as stubs go, use https://pypi.org/project/IceSpringPySideStubs-PyQt6/

[safe urchin]

Ooh, that could be very useful - thank you!

[safe urchin]

For example, I can't seem to find a QSS specification / reference anywhere - it's all been guesswork up until here by referring to examples at https://doc.qt.io/qt-6/stylesheet-examples.html

[eager beacon]

got you: https://doc.qt.io/qt-6/stylesheet-reference.html

[safe urchin]

jeez, my google fu really isn't up to par

thank you very much!

[eager beacon]

Your google skills are probably fine, that one is just buried and hard to find unless you actually take the time to read the stylesheet docs carefully and completely

If you scroll to the end of that page, there are some pagination links that might bring up a couple of other related pages you've missed

I think those are the ones that explain exactly what a sub-control is, which makes life with qss less confusing

[safe urchin]

That'll definitely come in handy, thanks!

[eager beacon]

sure

[safe urchin]

One last thing - are you aware of any forks/clones of the Sass compiler, for QSS? I've found one Spyder repository, but that's outdated and the code no longer works.

[eager beacon]

No, sorry I've never found the need to use one.

What would the benefit be exactly?

Keep in mind that qss != css, so there is a ton of stuff that you can't do with qss that you can with css. This is especially true for any css features that are even remotely new.

[safe urchin]

It's partially for some syntactic sugar, but the main reason is that I'm able to use modules and conditionals for a light and dark theme without a lot of repetition.

[eager beacon]

Hmm, well you can make it a little easier without one.

Do you know how to use pyqtProperties ?

[safe urchin]

I've searched it up, and it'll help with the light/dark mode switching, but I think I may just stick to having the sass compiler on my side for now just for the syntactic sugar.

There's only two syntax mismatches, that being the gradient functions and the exclamation mark for negation. Those could be resolved with a very simple substitution though

[eager beacon]

Okay, its probably easier if you see them in action than if I explain it.

1 moment

import sys

from PyQt6.QtGui import *
from PyQt6.QtWidgets import *
from PyQt6.QtCore import *

app = QApplication(sys.argv)
app.setStyleSheet("QWidget[white=true]{background-color: #f0f0f0}"
                  "QWidget[red=true]{background: #f44336}")

win = QMainWindow()
central = QWidget()
w1 = QWidget()
w1.setProperty("white", True)
w2 = QWidget()
w2.setProperty("red", True)

layout = QVBoxLayout()
layout.addWidget(w1)
layout.addWidget(w2)
win.setCentralWidget(central)
central.setLayout(layout)

win.setCentralWidget(central)
win.show()

app.exec()

for some reason the stylesheet reference does not cover the property syntax

You can get a lot done with this, especially if you combine properties with the stylesheet PaletteRole.

the properties aren't bound to being a bool either, you can use strings and I believe integers as well but you'd have to double check me on that

[safe urchin]

Ah, so setObjectName and setProperty are similar to HTML IDs and data attributes respectively - that makes sense

Sorry for the late reply, but thank you very much for all the help to this point!

[rocky dragon]

I think using requests/an async lib in an another thread may be nicer in some ways, but then you also have stuff running in an another thread which has its own potential complications

[safe urchin]

Is there a "standard" way to do this, or is it up to personal preferences or on a case-by-case basis?

[rocky dragon]

I don't think there's any standard way that's followed, but I think using python tools in an another thread and only sending the results through a signal is the more common approach

for qt's approach I have this util function, but with a chain of requests the callbacks break things up in maybe a bit unnatural ways

def make_network_request(
    url: str,
    *,
    params: collections.abc.Mapping = {},  # noqa: B006
    finished_callback: collections.abc.Callable[[QtNetwork.QNetworkReply], t.Any],
) -> QtNetwork.QNetworkReply:
    """Make a network request to `url` with a `params` query and connect its reply to `finished_callback`."""
    log.debug(f"Sending request to {url} with {params=}")
    if params:
        url += "?" + urllib.parse.urlencode(params)
    qurl = QtCore.QUrl(url)
    request = QtNetwork.QNetworkRequest(qurl)
    request.set_header(QtNetwork.QNetworkRequest.UserAgentHeader, f"{APP}/{VERSION}")
    reply = get_network_mgr().get(request)
    reply.finished.connect(partial(finished_callback, reply))

    return reply

It's of course only for the get and missing some things you may need, but that's roughly how it looks like

[shy torrent]

Is there any performance bonus of memory usage boon or so in using the concurrency of Qt compared to just using the ones of python itself?

[safe urchin]

I seem to be having some issues with these stubs as well:

Is there something I'm doing wrong here, or do the stubs need a little tweaking?

[eager beacon]

If you have a different stub file installed, you probably need to remove it and then reinstall the icespring stubs.

at one point there were some notes on the repos page about issues but from what I remember those were centered around use in PyCharm

[safe urchin]

I have followed the instructions to the letter, including removing PyCharm skeletons/stubs and making the directory read-only. However, the issue appears to be with the IceSpringPySide stubs

It thinks that the types of all the enums are Qt | Qt

[eager beacon]

Oh that! Sorry, I thought you were showing me that the docs strings weren't rendering on mouse over.

Yeah, so that had to do with the transition between versions 5 and 6. In version 5 PyQt had its own way of handling typing. In version 6 it was changed to use Python's Enum. The part where it says Qt | Qt is because the window type is an Enum which doesn't work with bitwise operators like |.

[safe urchin]

Ah, that makes sense then

I had a nosey around online and found https://github.com/python-qt-tools/PyQt6-stubs, which is not on PyPI but seems to work so far for me

[eager beacon]

I think I had to change it to use a different type of enum. When I finish cooking dinner I'll send you the file I made the changes in.

It won't fix everything, since I only changed one or two of them where the highlighting was driving me crazy

[eager beacon]

does this have doc strings?

[safe urchin]

No, it doesn't

However, I've got f1 assigned to automatically open the Qt online docs, so I've been fine without them

[eager beacon]

Ahh okay. That's pretty much the only reason I use the ice spring stubs because I hate having 5 tabs of docs open or having to use Dash constantly to do a quick lookup

Using cmd/ctrl+click on the function definition and having instant access to the docs has spoiled me

[safe urchin]

that's fair, I've gotten used to having a browser open at all times by now though

Thank you very much for all your help up until this point, hopefully that's typing issues resolved from here onwards!

Is it possible to somehow apply a style to only part of a QLineEdit's contents? I'm trying to create an autocomplete, and I'm looking for some way to "shadow" the predicted text using a dimmer font colour.

Never mind, this seems way too overcomplicated so I'll just do without it for now 😅

[eager beacon]

ehh, qss isn't great with stuff like that. The easiest thing I can think of would be to create a QLineEdit and change the color using the paintEvent .

You may be able to use QStyle to pull it off in a subclass also, but I don't know enough about that.

Could someone please explain what the difference between layout.addLayout() and layout.addWidget(widget); widget.setLayout() is please? The second just seems like an extra intermediary step, but I don't quite understand the benefits of it

Are there any curses users here? I have a probably obvious question about checking getch against a list of valid characters. I think it doesn't work because getch returns the ascii code. I'm not using getkey because for some reason it interferes with the display, makes things slow.

Current code:

legal = ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','0','1','2','3','4','5','6','7','8','9']

key = stdscr.getch()

if key in legal:
  printKey = True

Kinda rubber ducked it here. If I wrap my legal characters in ord() it will work. Is there a more elegant way to do this? legal = [ord('A'),ord('B'),...]

[eager beacon]

A layout used to organize and position widgets. A widget is a component that can be added to a layout. The main difference between layout.addLayout() and layout.addWidget(widget) is that layout.addLayout() adds a layout to another layout, while widget.setLayout() sets a layout for a particular widget. Unless you are dynamically replacing a layout, like if you wanted to change the what your widget renders, you would only use widget.setLayout() once in the beginning.

[safe urchin]

That makes sense, thank you!

[summer vigil]

Just make the original image transparent

hella late reply but people barely use this

[obtuse thistle]

you can map ord to your characters:

legal = set(map(ord, "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890"))

I'm trying to make like a search field in a command line terminal but it's not working out

[jovial depot]

Hi, I'm working on a Kivymd app. I have an text input, which calls my search function on every character added or removed. This is the behaviour I want, but there is a glaring problem. With every character I add, the API which does the searching gets called, which can take some time. And during this waiting time, my text input is completly frozen... Is there a way to still call the API, but also not let the text input freeze?

[eager beacon]

Check to see if the input has a returnPressed signal or something to allow you to only start the search when enter is pressed.

[jovial depot]

that's a good suggestion

I'll try that

What's this about? It popped up after I connected the result signal to a method

*** Sort Warning ***
Signals and slots in QMetaObject 'NeutronTab' are not ordered correctly, this may lead to issues.
1  Slot   _get_route()
2  Slot   _display_nearest_window()
3  Slot   _set_submit_sensitive()
4  Slot   _set_range(int)
5! Signal result_signal(PyObject)
6! Slot   _update_from_loadout(PyObject)

is the issue that I connect signals to slots of the object after a signal from it is connected (why?)?

[eager beacon]

Is it this? https://bugreports.qt.io/projects/PYSIDE/issues/PYSIDE-983?filter=allopenissues

[rocky dragon]

I don't think I have any duplicate class names

there is maybe weird multiple inheritance but that should be linearized by python so I don't think that could be the issue?

[eager beacon]

I'm not really sure, I've only seen that once before and thats when I was trying to use connectSlotsByName and messed up

[rocky dragon]

this is the class https://github.com/Numerlor/Auto_Neutron/blob/bug-branch/auto_neutron/windows/new_route_window_tabs.py#L42, if I connect the result_signal to a method in the window that creates this and after that run https://github.com/Numerlor/Auto_Neutron/blob/bug-branch/auto_neutron/windows/new_route_window_tabs.py#L233-L238 it starts popping up with the warnings and the signal doesn't work

[proven basin]

auto_neutron/windows/new_route_window_tabs.py line 42

class Tab(TabBase):```
`auto_neutron/windows/new_route_window_tabs.py` lines 233 to 238
```py
(
    journal.loadout_sig.connect(self._update_from_loadout),
    journal.system_sig.connect(self._update_from_location),
    journal.target_signal.connect(self._update_from_target),
    journal.cargo_signal.connect(self._update_from_cargo),
)```

[eager beacon]

If they use something similar to the behavior of a trie to resolve the names, I could see that being it, maybe.

How much work would it be to change one of the class names for a test?

[rocky dragon]

should be easy enough

didn't seem to have any effect with random names

[eager beacon]

Figures it wouldn't be that simple

given that _get_route(self) is mentioned with a ! next to it, and theres one in each tab and 3 of them emit something from inside the method.

I'd start there

[rocky dragon]

I think that's it just showing out of order entries, as with all the connections it shows

1  Slot   _get_route()
2  Slot   _display_nearest_window()
3  Slot   _set_submit_sensitive()
4! Signal result_signal(PyObject)
5! Slot   _update_from_loadout(PyObject)
6! Slot   _update_from_location(PyObject)
7! Slot   _update_from_target(PyObject)
8! Slot   _update_from_cargo(int)

I'll try to get a mre in a bit, though I don't really know what it could be as the only out of ordinary thing is the inheritance

[eager beacon]

Yeah, it's pretty hard to keep track of what each class in both files inherits, and their signals and slots .

[rocky dragon]

It looks like it's because of multiple QObject classes which may be doing something when the type is created?

from PySide6 import QtCore

class Object(QtCore.QObject):
    signal = QtCore.Signal()

class OtherObject(QtCore.QObject):
    0

class SubclassObject(OtherObject, Object):
    def slot(self):
        0


app = QtCore.QCoreApplication()
obj = SubclassObject()
app.aboutToQuit.connect(obj.slot)  # random signal
obj.signal.connect(print)
app.aboutToQuit.connect(obj.slot)  # random signal
app.exec()

reproduces it

[rocky dragon]

I'm trying to make things more reusable as the behaviour was previously all just a huge class that I put off refactoring for over a year, but the subclassing I have going on is a more complex even if it's more extensible, if you have any suggestions on how to structure things in a nicer way I'm open to them

huh it works if it inherits from (Object, OtherObject) instead of what it is above

[eager beacon]

Oh, yeah.... I remember something along those lines. Like when you use inheritence you can't have widget,object, or maybe its the other way around(cant remember). So It wouldn't surprise me if the example you posted does cause issues.

Was it just trial and error, or how did you figure it out?

[rocky dragon]

inheritance was the only thing that came to mind, so I replicated that and then chopped it down

seems to be working fine with the inheritance reordered but that also messes up what I had in mind with it

[eager beacon]

which class did you have to change?

[rocky dragon]

the Tab subclasses to have Tab first instead of second

but that also has me passing args in their init that should be handled by the other inherited class

[eager beacon]

The part about the args is worth adding a comment if you're not the only maintainer

and maybe even worth it if you are

Simply doing

doesn't open a window either but the signal works cause the print statement gets called.

I'm trying to match up the background of a widget inside of a QTabWidget with that tab widget's background color, but changing the Window role of the palette makes widgets within that widget's layout lose styling, what could be the issue there? e.g. with the palette unchanged a line edit looks like https://i.imgur.com/ydm1uP2.png (but with the wrong background color) and adding the palette turns it to https://i.imgur.com/9cSzJKW.png

[mighty frigate]

@grave flame https://doc.qt.io/qt-6/qcombobox.html#currentText-prop

@rocky dragonwhy not set the background-color to "transparent" in the widget ?

[grave flame]

Thank you

[mighty frigate]

@rocky dragonstyles and palettes don't work together, you have to choose one or the other

[grave flame]

@mighty frigate the issue is that QDialog#exec returns only selected button, not combo box choice

I don't know how to make it return both button and combobox choice

[mighty frigate]

@grave flameshow me some code

[grave flame]

class RemoveFolderDialog(QDialog):

    def __init__(self, folders_list):

        super().__init__()
        self.setWindowTitle("Remove folder")

        QBtn = QDialogButtonBox.StandardButton.Ok | QDialogButtonBox.StandardButton.Cancel

        self.buttonBox = QDialogButtonBox(QBtn)
        self.buttonBox.accepted.connect(self.accept)
        self.buttonBox.rejected.connect(self.reject)

        self.layout = QVBoxLayout()
        message = QLabel("Which folder would you like to remove?")
        self.layout.addWidget(message)

        self.comboBox = QComboBox()
        for folder in folders_list:
            self.comboBox.addItem(folder)

        self.layout.addWidget(self.comboBox)
        self.layout.addWidget(self.buttonBox)
        self.setLayout(self.layout)

and here I am calling it upon someone clicking the Remove folder button

def remove_folder_button_dialog(self):

        if len(self.folders_list) == 0:
            return

        dlg = RemoveFolderDialog(self.folders_list)
        button = dlg.exec()
        # by default, #exec returns either 0 or 1 depending on if I clicked Ok or Cancel button

@mighty frigate ^

If I click Ok button, it's supposed to return 1 and combobox choice

[mighty frigate]

dlg isn't destroyed after the exec, you can still retrieve the combobox

dlg.comboBox.currentText()

@grave flame

[grave flame]

lemme try

it's working, tysm

[rocky dragon]

Are they? I meant the application style (set to fusion); it works everywhere else except the widget in the scroll area

In what way do you find it terrible? The normal Qt documentstion is generally great from my experience

[mighty frigate]

@rocky dragon@worn viperthat's odd because the Qt documentation is probably one of the best you'll ever find. A very large part of Qt is well documented, and there's tons of examples. Yes it's in C++ but it doesn't matter as the framework is the same in C++ and in python, with very few differences.

if you really want a documentation in python for Qt, here's one but I warn you, it's significantly worse : https://www.riverbankcomputing.com/static/Docs/PyQt5/

@rocky dragonshow me some code about your problem pls, preferably the smallest sample you can do

[molten latch]

.pin

[tawdry mulch]

What issue

[rocky dragon]

Looking at it more in depth, it looks like the widgets are using the Window color role for edges, which I was overriding on the parent so the outlines disappeared or were muted. Not really sure how to have it use the tab's background color in a nice way

I suppose I could set the palette to the default one on every child to prevent them using the scroll area widget's palette

[median bridge]

The top bit so it covers the grey area. I created a frame for the treeview, but it isnt using the whole frame

[tawdry mulch]

Are you using pack or grid

[median bridge]

I'm using pack for both

Would using grid be better?

[tawdry mulch]

Try using the fill property

[median bridge]

On the frame or on the treeview?

[tawdry mulch]

fill='y'

[tawdry mulch]

Both I suppose

[median bridge]

Didn't work :(

[median bridge]

I just found out removing the elif == "Completed ends up filling the whole thing

idk how tho

[tawdry mulch]

Ah well, I don't have a runnable example, that's y Idk the reason

[median bridge]

Should I send you my code?

does anyone know how can i make a game overlay like steam for ex using pyqt

i want to make a ui that i can access inside the game without leaving

[mighty frigate]

@rocky dragonit's hard to tell without seing what is actually happening

@buoyant gobletthere's 3 main things you need to do :

• register a global shortcut (for example : https://pypi.org/project/global-hotkeys/)
• access the properties of the focused window : (for example : https://stackoverflow.com/questions/7142342/get-window-position-size-with-python)
• you'll need to set some specific window flags to your QMainWindow to hide the windows control :(see https://doc.qt.io/qt-6/qwidget.html#windowFlags-prop and https://doc.qt.io/qt-5/qt.html#WindowType-enum)

From there you should be able to make whatever you want. This will only works on windows.

[rocky dragon]

The tab widget renders its background with a modified button color, but the scroll area uses the Window color - I want it to be transparent or use the same color as the tab for its background

from PySide6 import QtGui, QtWidgets
from __feature__ import snake_case, true_property  # noqa: F401

class Window(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()
        self.tab = QtWidgets.QTabWidget(self)
        self.set_central_widget(self.tab)

        self.scroll_area = QtWidgets.QScrollArea(self)
        self.scroll_area.frame_shape = QtWidgets.QFrame.Shape.NoFrame

        self.widget_in_scroll_area = QtWidgets.QWidget(self)
        self.scroll_area.set_widget(self.widget_in_scroll_area)

        self.widget_with_scroll = QtWidgets.QWidget()
        self.layout_in_widget_with_scroll = QtWidgets.QVBoxLayout(self.widget_with_scroll)
        self.layout_in_widget_with_scroll.add_widget(self.scroll_area)
        self.tab.add_tab(self.widget_with_scroll, "")

app = QtWidgets.QApplication()
app.set_style("Fusion")
pal = app.palette()
pal.set_color(pal.Button, QtGui.QColor(50,50,50))
app.set_palette(pal)
window = Window()
window.show()
app.exec()

the scroll area sets autofillbackground to true for the widget added to it, but changing that back to false had no effect

[digital rose]

tkinter, i need to find a way to make it so a image can be a button?

[mighty frigate]

@rocky dragonhonnestly I don't know how to use palettes because I never use them, but it looks like to me you could use stylesheet

try this

from PySide6 import QtGui, QtWidgets
from __feature__ import snake_case, true_property  # noqa: F401

class Window(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()
        self.tab = QtWidgets.QTabWidget(self)
        self.set_central_widget(self.tab)

        self.scroll_area = QtWidgets.QScrollArea(self)
        self.scroll_area.frame_shape = QtWidgets.QFrame.Shape.NoFrame

        self.widget_in_scroll_area = QtWidgets.QWidget(self)
        self.widget_in_scroll_area.setStyleSheet("background-color: transparent;")
        self.scroll_area.set_widget(self.widget_in_scroll_area)

        self.widget_with_scroll = QtWidgets.QWidget()
        self.layout_in_widget_with_scroll = QtWidgets.QVBoxLayout(self.widget_with_scroll)
        self.layout_in_widget_with_scroll.add_widget(self.scroll_area)
        self.tab.add_tab(self.widget_with_scroll, "")

app = QtWidgets.QApplication()
app.set_style("Fusion")
window = Window()
window.setStyleSheet("QPushButton {background-color: rgb(50,50,50);}")
window.show()
app.exec()

wait you want to change the tab background, right

use this : https://doc.qt.io/qt-6/stylesheet-examples.html#customizing-qtabwidget-and-qtabbar

basicaly

tabWidget = QTabWidget()
tabWidget.setStyleSheet("QTabBar::tab { background-color: transparent;"}

something like this

[grave flame]

@mighty frigate hey, do you know how can I set vertical scrollbar to bottom in QTextEdit?

[mighty frigate]

@grave flameisn't there a scroll() func or something ?

@grave flametake a look at QTextEdit and QScrollBar documentation

it's in there somewhere

[grave flame]

I did, couldn't really find anything

[mighty frigate]

@grave flameQTextEdit has a verticalScrollbar() getter (https://doc.qt.io/qt-6/qtextedit-members.html), which has a scroll() function (https://doc.qt.io/qt-6/qscrollbar-members.html)

[grave flame]

uh

[mighty frigate]

QWidget also has a scroll() function (https://doc.qt.io/qt-6/qwidget.html#scroll-1)

[grave flame]

I couldn't find that here https://doc.qt.io/qtforpython/PySide6/QtWidgets/QTextEdit.html?highlight=qtextedit

[mighty frigate]

@grave flamedo yourself a favor and use the cpp documentation

I keep telling it to ppl and they never listen

[grave flame]

Okay

[mighty frigate]

it doesn't matter it's cpp, the calls are the same, the structures are the sames, the flags are the sames

Hello I have a problem with filling in this shape with a color

I would like the whole shape to be red on the inside, but it's only filling in the area between points

Hey there so I'm trying to make ca calculator in python and tkinter an I've added almost everything that I've wanted except one thing; being able to add custom powers to equations, what I mean by custom powers is not just being able to do x to the power of 2, so you could do x to the power of y; you would choose both numbers, I've tried updating each label and updating the out put but I just can't figure out how to do it, please help. Here is the script: https://pastebin.com/WAq8U3QS

[buoyant goblet]

@mighty frigate bro am not a spammer i got hacked before thats why

[past herald]

Is the problem the calculation, or the ui showing it properly?

My first idea is to implement a boolean like : isWaitingForCustomPower

That gets set to true when you press the x**y button

So the next number(s) you type are spawned at the top

[mighty frigate]

@buoyant gobletidk if I'm being honnest I just don't like pm from strangers. As I said if you want help, just explains your problem and ping me. i'll take a look when I have the chance.

I'm having some issues installing pyqt5 when I found out that pyqt6 is a thing. I've never really built any GUI application in python before, only in C# using windows forms.
I'm not sure how to ask this as you can really make anything work but, is pyqt6 a viable way to create GUI apps with 3.10?

[buoyant fulcrum]

I’m getting this error in my exe app, which I wasn’t getting in my script. Could someone please help me?

Does Tkinter fuck up when placed in an exe?

I added a “From Tkinter import message box” to my code now. But since I have from Tkinter import star, I didn’t think it would matter.

[mighty frigate]

@real jackalyes ? why not ?

I'd probably use PySide6 tho

also you need to ask yourself how you're planning to distribute your app and to whom

because imo python apps aren't made to be distributed to non technical clients

[buoyant fulcrum]

This didn’t help

Could someone please help me?

[celest ledge]

have you imported messagebox?

[buoyant fulcrum]

It works in the coding environment

[buoyant fulcrum]

Yes

Twice tbh once as a star import and then I just tried doing it separately too

[rocky dragon]

How would I correctly create a dynamic QCompleter for a line edit? I'm making query requests with the line edit's text and updating the model from their results, but the completer doesn't show new suggestions from that when the model is updated through a slot that's called later. e.g. here it doesn't work with the timer (i.e. request finished signal), but works if called directly

from PySide6 import QtCore, QtWidgets
from __feature__ import snake_case, true_property  # noqa: F401

class Window(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()
        self.main_widget = QtWidgets.QWidget(self)
        self.set_central_widget(self.main_widget)
        self.layout_ = QtWidgets.QVBoxLayout(self.main_widget)

        self.line_edit = QtWidgets.QLineEdit(self)
        self.layout_.add_widget(self.line_edit)

        self.completer_model = QtCore.QStringListModel(self)
        self.completer = QtWidgets.QCompleter(self.completer_model, self)
        self.line_edit.textEdited.connect(self.update_model)

        self.line_edit.set_completer(self.completer)

    def update_model(self, query: str):
        QtCore.QTimer.single_shot(0, lambda: self.completer_model.set_string_list([query + "completedtext"]))
        #self.completer_model.set_string_list([query + "completedtext"])

app = QtWidgets.QApplication()
window = Window()
window.show()
app.exec()

[rocky dragon]

tkinter.messagebox is a package that's lazily loaded, try importing it directly in your script, or adding it to pyinstaller's hidden imports (if you're using pyinstaller)

[buoyant fulcrum]

Ooo

I’ve just tried a direct import by doing “Tkinter.messegebox as messsgebox”

But I’ll try pyinstallers hidden imports if that doesn’t work. (I have no idea how to do that, but I’m sure google can help lol)

Thank you

[buoyant fulcrum]

It worked, thank you

[buoyant fulcrum]

Do you think this could apply to other libraries that are having random issues that only exist in exe?

[mighty frigate]

@rocky dragondo you know the string list you want to complete the lineedit before typing ?

[rocky dragon]

No, it's created from the text in the line edit

[mighty frigate]

Ok I need to do a bit of research then

I think the problem is that the slot is called after the text is edited

meaning you're modifying the model when the completion is already done

for example, if you type "t" then "c"

it completes with "tcompletedtext"

from https://stackoverflow.com/questions/1927289/how-to-update-qcompleters-model-dynamically

changing the signal connected from textEdited to textChanged fixes the issue

but in my experience you could have unwanted triggering with textChanged , you'll need to try for yourself @rocky dragon

[rocky dragon]

isn't that post saying the opposite?

[mighty frigate]

ah yes it does I can't read

[rocky dragon]

but anyway it doesn't seem to change anything

[mighty frigate]

anyway, it's working with textChanged soo

it's working for me with textChanged

I'm using PyQt5 tho

[rocky dragon]

maybe something changed then with qt6 or how the signals are set up by the different bindings

[mighty frigate]

there's ways, but it's kind of ugly

[rocky dragon]

What I found online seems to suggest something like the above should work, but yeah

[mighty frigate]

first thing that comes to mind is overloading QLineEdit, overloading the keyPressEvent, and feed your completer there before calling the primitive of QLineEdit

basically

class PrecompletedLineEdit(QLineEdit):
    def __init__(self):
        super(QLineEdit).__init__(self)
    def keyPressEvent(self, event):
         if completer():
             completer.model().setStringList(event.key()) # or something
         QLineEdit.keypressEvent(self, event)

ps it's untested pseudocode, pls dont trust me on its validity

but that's the idea

[rocky dragon]

I can't really update the model on the event because the completion list is from a request to a remote server

[mighty frigate]

and how are you fetching that

more like where are you fetching that

[rocky dragon]

It's what the timer simulates. The chain of events is textEdited->make_request_with_text->update_model_from_response

[mighty frigate]

I think I might have something

[rocky dragon]

you can install an event filter on the text edit's viewport or whatever actually receives the wheel events

[mighty frigate]

Views are simple, Models are not

QTreeWidget or QListWidget might be more like what you want

@rocky dragon

app.exec()

i'm so close

the popup isn't at its right position and not the right size either

but it works

[rocky dragon]

I've noticed that it appears if I remove text with backspace, assuming it's because it's matching what's in the model before it's updated maybe I could have some dummy value in the model that'd always match

but then it may also appear when there's no completions available

[mighty frigate]

@rocky dragonyes you'll need to tweek it a bit

but as a poc it seems to work

[rocky dragon]

I've noticed the complete method of the completer that I managed to miss two times which mostly does what I need, but it causes flicker as the popup is hidden and then shown when updated

[mighty frigate]

I'm wondering if you're not better off handling the completion yourself enterely

without actually setting the completer to the lineedit
