okay guys, i'm in the need of a gui module in python.
Altho i have a few requirements:
- non web based, can be compiled/executed offline, etc
- modern. By that i mean something which isn't based on old code but implement new modern concepts like object oriented, implement concurrency natively or make it easy to implement
For example, I consider tkinter as really ugly and old, especially when it comes to implement parallelism it's a big mess, and not mentioning how the.pack()are annoying to put after each action, and how illogical the module is when it comes to documentation and architecture in general... - Works cross platform. At least for windows, mac
- Easily convertible to .exe or application file according to the platform
- native to python, and not stuff like Processing which have to be converted to another high level language and disable the user from using installed python libs or disable the user from using python completely and limitating in some ways, like making global variables act weirdly or some shit

how do i access a class from the outside? :S

ClassMainWindow = GUI.Ui_MainWindow
when i write this
ClassMainWindow.Brightnessslider

AttributeError: type object 'Ui_MainWindow' has no attribute 'Brightnessslider'
i know that Brightnessslider is inside the class and under the function

It's likely an instance attribute so you'd need an instance of the class.

@vast tiger I don't know exactly about PyQt5 designer, but I have had the same problem as you. I was using grid layouts but things were not appearing exactly where I want them to appear
From hours of reading, I learned that you can create your own layouts, you can customize a LOT of things using code, so I completely ditched qt designer.

I was thinking about UI files for qt to replace my longer inits and setup methods but haven't looked at them before because it didn't appeal much.
Is there something like a reference for how to use them with PyQt? Mainly if I should attempt to write them myself (and resources for that if yes) or just attempt to use the designer where possible.
And things like if there is some inheritance of basic layouts
sudden coral
I think QML was intended for that
rocky dragon
When I tried QML it was Just QtQuick and things like that instead of normal QtWidgets and didn't support them iirc

Do any GUI libraries use html?
hollow mist
html? for the controls? No. but qt uses css
You can also use electron and flask if you want to use python
Can any display html? Many
rocky dragon
If going with python because the .ui seems more complicated than I'd want for manual work, would you separate the UI bases from logic with files (popups and popups_gui as an example) and inheriting the bases or just keep the methods separate
sudden coral
Yes, I would try to keep it separate
Maybe subclassing isn't the best way. There are various design patterns out there that you could look into and try to apply to Qt, if possible.
viscid ginkgo
@dawn glacier Yeah, I need a way to refresh a frame in the stack. I found a work around by reloading the data.
rocky dragon
I have this class as an example, I also have a Hub class that connects workers with various windows. https://paste.fuelrats.com/urexocixos.py
I can see how things like the populate_combo and load_journal methods could be moved there, but for the worker_signal which can't be moved outside of that class, how should it be handled? Connect it to an another signal in the Hub? Also feels like the Hub class could get too big if I move it all out from there becuase I have some (now messy) ui classes which have 4-5 methods for adding and handling their data
eager vigil
I'm moving to python from html/js. Which GUI library would you recommend?
alpine blaze
depends on what you want, pyqt/pyside are common for desktop applications, kivy is also a possibility, with the benefit of multitouch interactions, and availability on android/ios, and with a more pythonic api, but looks less native on desktop.

Is tkinter widely used in the industry? Anyway i’m learning tkinter right now is it similiar to Pyside2?
I don't think so, it has outdated code and has elements looking like from Windows 98 alone, i'm not sure really. But I would say no if it was a serious application, however it is fairly easy to learn without mentioning illogical programming.
digital rose
Alright gonna learn pyside2 then! Anyway can Kivy support iOS pretty well? I want to build like a productivity app for myself, and i heard that Kivy supports crossplatform what kind of quality i can expect from it?
alpine blaze
kivy does support iOS as well @digital rose
kivy has the particularity that it uses its own widgets, so your app will look about the same on windows, osx, android, linux, ios, some people like that, some don't, i find this very freeing and desirable if you are ready to give a particular design to your app, as kivy allows for easy customization of your widgets (and even creating thom from scratch, it's really easy), you can really go where you want in matter of design. For this reason, quality depends a lot on you, the default look being quite modest.
digital rose
I will use kivy in my personal project then xD i don’t want to learn react native or swift atm so i think i’m just going to try them all, thx for the help guys!

you do need a mac with osx and xcode to test on an iphone btw, it's now free to test on emulator and your own device i think, but to publish on store to share with anybody, you need to pay the apple tax, i think some $100 a year.

It was pyqt5 but uh I figured it out, just made another class and modified and modified a bit the original btn class
With signals, but yeah if you know another, better, way to do it tell me 
odd hamlet
so I've been reading through a bit of the kivy docs and im not quite sure wether im just missing out on something but is there a go to way to spread your widget definitions accross multiple files?
with widget definitions meaning both the kv files but also the logic implementations in python
odd hamlet
anyone?
alpine blaze
you can use the Builder class to load files/strings of kv definition
young timber
@odd hamlet yes. here's an example from the code jam: https://github.com/python-discord/code-jam-6/tree/master/inquisitive-investigators/rex_explorer
alpine blaze
the Factory class can also be used to register widgets in modules without loading them before, so they are loaded as needed.
but it's true that while the tools are here, the manual for how to use them is not really present.
odd hamlet
good so i didnt miss out on anything^^
young timber
@timber prism i'd recommend either kivy or pyqt
timber prism
So these help you rapidly develop GUIs with python.
What about the rest of the application. Common functions that many apps need?
young timber
could you elaborate on common functions?
what common functions are you looking for?
timber prism
Its a broad question. But you can think of features that many apps use. For example dialog boxes, importing CSV files, saving preferences, supporting fonts.
Then if your talking about types of apps you could think of all the features that every app of a certain kind always has.
Screen Scraping
Printing to PDF
Conditional Font manipulation (colors, size, style)
ETC
young timber
many of the GUI features itself are ready for you to use in kivy & pyqt including dialog boxes, different fonts, and many different wigets. dealing with csv files, you can use the csv module. for printing to pdf, pyqt has a way to do that
timber prism
Ok thanks, its good to know there is something out there for the GUI part.
Now I need to look for the app features part.
young timber
there's plenty of libraries out there; i'm sure there's one out there for your needs
timber prism
Thanks for your help
young timber
no problem!
alpine blaze
Kivy has plyer to put commonly needed mobile feature together
And the underlying libraries, pyjnius and pyobjus, allow calling java and objective c code on android and ios, to use other system functions.

@alpine blaze what is the benefits of using pil as the text renderer? sdl2 does work on my system, while pil needs pillow installed I think.
alpine blaze
it's an alternative, i rarely use it, i don't think there is any particular advantage, i think we had it before the switch to sdl2, and there is no particular downsides to it.
pillow is also an alternative image loader, that can load a couple things that our sdl2 provider can't, like gif, so it can be worth having for that.
sand warren
that is interesting, thanks.. ill keep that in mind if i need to use gifs
alpine blaze
yeah, it's been there since basically the dawn of times, in kivy history.
if you need animated things and have a choice, we support a weird thing that works well for us, just put pngs in a zip, and use that as source, functionally identical to gif, but with real transparency, and usually smaller in size.

Depends really, do you want single line or an entry that supports mutiline?

but it depends on what you want, it's more fit for some things than for others
and for others, pyqt/pyside2 is certainly a better option.
subtle gust
pyqt and pyside2 are the same thing?
rocky dragon
they wrap the same c++ framework
in some cases they are interchangeable, pyside2 is the official one but when I tested it I had some problems (that could be only relevant in the scope of my app)
qt also offers a lot more than ui so it's a bit more heavy to download
digital rose
Hello guys
I am new here
Is there any module to use other than tkinter(simpler) for making gui
rocky dragon
both of the mentioned above apply here
qt has a more similiar look and utility as tkinter, and kivy gets you more freedom in building it how you want it but doesn't have premade stuff for desktop etc.
fallen oxide
@digital rose Sorry, I wasn't here
But this is a better channel to ask about Qt
Anyway, I'm not convinced you quite have pyqt5 installed (or pyside2) - you may have installed it to your system python, but if you're using a tool like pycharm then you may also have a virtualenv it needs to be installed to
digital rose
Ah, I see
fallen oxide
so, are you using a tool like that?
digital rose
I have JetBrains dotPeek 2018.3.4 installed so maybe it's causing a conflict?
digital rose
Win10 and I used cmd.exe and installed via pip install PyQt5
fallen oxide
So if you did python in a terminal, can you import it?
digital rose
I followed these instructions essentially: https://poorlydocumented.com/2019/11/installing-corentinjs-real-time-voice-cloning-project-on-windows-10-from-scratch/
fallen oxide
That doesn't mention PyQt at all
just open a cmd, python
then do import PyQt5
see what happens
digital rose
It's in the requirements text

So when I do pip install -r requirements.txt it should have installed it anyways

I am currently trying to build a linux desktop environment on top of i3wm. To navigate through things like settings and applications, I plan on using something similar to dmenu. Could someone point me towards how to make such an application?
alpine blaze
demenu is pretty simple, you just need to draw a borderless window and to take keyboard inputs, filtering through a list of options.
basically any UI framework will allow you to do that
you might want to have a look at rofi though, it's a bit more advanced and also has the possibility to add providers and to display icons and such
switched from dmenu to it a year ago i think.

Hello everyone. o/
I really glad to become a part of this great community. I hope i'm not going to bore you with my newbie questions. :)
As a newbie coder i'm looking a way to store my images. Right now i encode it to strings and store it in .py as dictionary, then i call from main file.
Is there any way to do that more efficient?
I already tried json, but have no luck to use it in tkinter. Maybe something else what i should read?
EDIT: Also, English is not my native language. So, sorry me, guys for any grammar mistakes.
topaz aurora
I'm not entirely sure what you are trying to make with Python. But there are libraries meant to work with images in an effcient way. Are you trying to display the images in a GUI program, like a picture viewer? Or are you trying to edit the images in some way?
timber gorge
I mean GUI elements, like buttons, windows, background. Or something else only for interface.
topaz aurora
I don't follow what you are trying to do. I don't really know GUI programming or Tkinter so it's hard for me to say. Maybe posting some of your code, or some of the json can help other people help you
sudden coral
What's wrong with storing them as regular image files?
timber gorge
Its almost 50 files. :)
Would be good if i can store it without ability to inspect.
sudden coral
What do you mean "without ability to inspect"?
timber gorge
look, copy/paste, use it without permission.
sudden coral
I can't help you with that. I'm not familiar with how to accomplish that, but my understanding is it's not really easy to prevent that with Python.
If someone tries hard enough and puts enough time in, they'll be able to get those images
topaz aurora
Yep. Python seems fairly easy to 'get into' with the REPL and all those other fun features
sudden coral
Anyway, since you dislike many files I get the sense that you want your application to be in a single file? If that's the case then you should look into packing it into a binary/executable (e.g. .exe file on Windows) rather than jamming everything into one .py file.
timber gorge
Hm, sounds good. Its possible to pack all .py files in 1 exe?
I have 3. Main, system, image data.

You're welcome

if you are comfortable enough with OOP, i'd recommend kivy, (but i'm biased, as one of the devs)
digital rose
Thanks for the quick response. Is it easier to get started than tkinter?
the gallery apps are beautiful
alpine blaze
thanks :), i don't think tkinter is specialy easy to get started with, it has a lot of weirdness imho, and the doc is pretty spread out.
kivy is not perfect either, but i do believe it's easier to use than tkinter.
it's been a long time i didn't do any tkinter, but i don't think it changed much.
digital rose
great! Where do you recommend to get started with kivy?
digital rose
Nice, thanks! I will give it a shot 🙂

timber gorge
Anyone knows if i can use .cur encoded with base64 in tkinter?
timber gorge
Hm. Still have no luck with pyinstaller.
In tkinter Label config i have ````cursor="@cursor-exit.cur"and for root i also useroot.iconbitmap("icon.ico")```
Then i pack all my scripts with pyinstaller with commands:
• --add-data "icon.ico;icon.ico"
and
• --add-data "cursor-exit.cur;cursor-exit.cur".
And anyway .ico and .cur still should be in one folder with .exe. Or i will get message Fatal error detected
Anyone could help me with that?
sudden coral
I'm about to head off but I just saw this and I suggest you clarify what the problem is. You've stated what you've tried but not what is wrong.
Is it the penultimate line? That despite including them with --add-data, if the files are not present beside the exe, you will get a fatal error?
timber gorge
Oh, really sorry. I will try to clarify.
I'm trying to pack all files to one .exe. I have files beside python scripts:
icon.ico and cursor-exit.cur. if i even pack it with --add-data i can't launch my .exe without this files. That's the problem.

I need help to select my first library for user interface, i think Kivy is the best for her compatibility
wispy oar
I have an assignment which is to simulate a lift algorithm and optimise it to be time efficient for different numbers of people requesting the lift at various floors. I was wondering which Python library would be most recommended for this assignment.
It would be a desktop application, and I've done a bit of research beforehand; it seems like PyGame might be a good option, but I was also wondering about PyQt5?
I have some experience with PyQt5 so it would be quite easy for me to get into, but would it be appropriate?
I don't think it needs to be animated, but I've heard PyQt5 can have animations as well (although it seems harder than PyGame)
I was thinking I could simulate it with blocks representing floors, and the lift being a coloured block, with the floor changing colour when the lift is on that floor
real jolt
Id pick the simplest solution tbh, it seems simple enough and its representation doesnt really need to fancy unless you get marked down for it.
wispy oar
So do you think PyQt5 would be the simplest solution in my case? I already know how to design the interface through Qt Creator and get it linked up, I'm just wondering if it would have any limitations for my use case here
real jolt
If you are most comfortable and have experience then yes.
wispy oar
So I started my basic interface
And I wanted to have blocks on the right side of the grid to represent the floors, then I'd change the colours of them when the lift is on that floor
But I'm not sure how to create the blocks
Would I just change the colour of the coordinates of the grid in the driver code?

What would be the best bet for making a modern style GUI?
rocky dragon
qt5 or kivy, kivy will be more ready to use with a flat modern design but needs more work for a normal desktop app if you're also aiming for that
qt is a bit harder to customize
digital rose
Are any of them easy to use?
rocky dragon
both are fairly easy with their own quirks if you have a fair understanding of OOP
digital rose
isnt kivy mainly for cross-platform?
rocky dragon
it's one of its aspects, qt can also do that but isn't as suited to mobile afaik
but for desktop both are fine (depending on the app)

Anyone who knows Tkinter can help me?
I'm trying to get it so when they have entered the IP range and they click the "click to scan" button it runs the code gets the information stored inside the ip variable and prints it out where it says scan_result = scan(ip)
at the moment it just prints out the print stuff i made without any Ips because i want it to get the IP the user gave in the input box and use it
I have a feeling im close to getting it right but maybe i need to rearrange my code or add something
Im new to python and tkinter so if anyone would give me a hand that would be great
alpine blaze
kivy 1.11.1 doesn't support 3.8 (at least, that's the tl&dr version), either use 3.7 or use the kivy pre release packages.

worldly venture
I got a strange bug on tkinter. I am working on a text editor, and I want to remove the text field when there are no file tabs open
I want to first prompt the user if he/she wants to save the file before destroying it completely
Regardless of the results, the app will then wipe out the text field with .delete("1.0", tk.END)
and then text_field.pack_forget()
The problem here is that the .delete part never comes through
The text_field disappears, but the text itself is still there
It only works when I comment out the save_file() functionn
Is it because of the filedialog.asksaveasfile() function?
What it looks like, after pack_forget():
Any help or ideas will be greatly appreciated.
alpine blaze
@dawn glacier yes, xsel and xclip are optional dependencies for clipboard handling.

That sounds like an external os tool dependency

How can i make a button or a label you can hover on and click in kivy?
dawn glacier
I am trying to make a layout when every row is a hoverable and clickabe item with some data on it
Like
tribal path
recycleview as a starting point maybe, hover is watching something like the cursor coords
dawn glacier
Hmm
alpine blaze
well, making a button is not a problem, i assume, making a list of them can be achieve in a number of ways, and recycleview is a very good one if you have a lot of them and want to be data driven (and if the layout options fits your usage, as it seems to be the case there).
so is your question about handling hovering events? or about using something like the recycleview for it?
olive slate
How can I make it so when a button is clicked, a new "window" is opened? Like for example how when you login somewhere youre taken to another display. For example, you login and then the display switches to gamemode options. Sorry if Its nit explained great
alpine blaze
@dawn glacier https://gist.github.com/126e1481d3d588f14c617a7fcbc38b5d
(though there is one problem remaining, as it pos doesn't actually change when the scrolling happen, as it's relative, so one would need to bind to scroll_y of the recycleview as well, but passing that information around is not really convenient, so i stopped, there not knowing if that was a problem for you or not)
alpine blaze
yw 🙂
dawn glacier
rgba: C('222222BB') if self.hovered else C('00000000') this is really cool, didn't know about this attr
Or on this button at all
I probably missed some docs
alpine blaze
i created the attribute for this class, it's not something that exists in kivy
but as you see, it's not really hard to implement
alpine blaze
just add or remove things from the data dict
dawn glacier
Cool
alpine blaze
i kept things simple there and managed the state directly in the widget, but in more complex recycleview usecases, you want to save the modified things into the data dict and let the dispatched state update the graphical things
dawn glacier

so, I know this is a dumb question, but I'm not sure what I should google search to get more information about it. This is my first time making a UI for a desktop application, and I'm not sure which functions of my app would belong under the different File, Edit, and View menus in the top bar, and I was wondering if there was some kind of best practices document anyone could recommend?
lunar kernel
hey any idea about which optimizer is used in image classification model compilation?
using keras?
alpine blaze
@clear kernel well, usually file contains operations that are relative to the file/document as a global thing, so load/save of course, but also whatever touches its metadata, and edit would be more about what modifies content in the document, view is for whatever changes how you view and interact with the document. Of course, if your program is not an editor of any sort, the first two ones are probably totally irrelevant, and the 3rd one might be as well.
@lunar kernel i don't think that's the proper place for that.

How can you customize the scroll bar of a QScrollArea in PyQt5?

Most come from other languages with an internal event loop
Think you can do some more native like integration with kivy but no idea there
devout dawn
You think in the future asyncio packages will be more popular?
rocky dragon
in general, probably; for GUI can't say because it's pretty hard work and like I said coming from other languages it's using its async or their own event loop
you can still hook into that but it'll be harder than just creating objects and getting nice coros directly

The two parts will be to Frames, one on the left and one one the right. The one on the left will be wider than the one on the right - I would like it to be something like 0.6 of the screen width and the right frame to be 0.4 of the screen width, but that something that I would like to be able to easily change I would like to. Inside each of this frames I would like to put a Text widget that will take all of the frame area. In addition, I would like to add a scrollbar widget to the right of both of the Text widgets. In addition I would like to add line numbers to the left of the left Text widgets (I saw someone that that showed how to do it in a stack exchange post, I can send the link if it's needed, it may requaire another Frame).

Hello every one, just a couple of questions.
What are the frameworks out there for creating UI on python and do you recommend some of them?
alpine blaze
pyqt/kivy/tkinter/wxpython/pygi (for gtk) and quite a few others
i'm biased towards kivy, as i find it more fun to use and allowing for more freedom, and portability to android/ios is a pretty strong point imho, but it's certainly less integrated on desktop, and does suffer from some limitations, so there are cases where that's not what you want to use.
and also, i'm a contributor to it
i would say pyqt is certainly the best alternative, when kivy is not what you want, pyqt certainly is
(pyqt or pyside, they are almost the same thing)

Tkinter is pretty basic afaic. If your program is simple and doesn't need to look flash I guess it does the job but if the GUI is substantive I'd look into other options

How to return func value from a QThread?
Let's say I subclass QThread class like this ```python
class AThread(QtCore.QThread):
def __init__(self, func, *args, **kwargs):
QtCore.QThread.__init__(self, *args, **kwargs)
self.func = func
self.args = args
self.kwargs = kwargs
def run(self):
return self.func(*self.args, **self.kwargs)
That won't work and it'll say TypeError: invalid result from AThread.run()
rocky dragon
What are you trying to do?
run should not return anything, use signals for communicating your results
wide stump
@rocky dragon I wanna run func() in a QThread by calling AThread, and then get the return value
suppose the func is like this
def func():
return_value = 'return'
return return_value```What are some basic user interfaces, I just want an all white text box
wide stump
Oh my god, I've come up with an idea, which is running the Start class (the one that starts multi threading) in another thread to avoid blocking the mainloop while waiting for return results from threads, and this is what I got
This is so fucking dumb
digital rose
Ok thank you

Could someone help me with why my method run_sim() doesn't use the new parameters from save_sim() in my program? https://pastebin.com/srMec8qe
For example, if I enter the values of 10, 5, 5, 5, it will still use the defaults of 10, 0, 0, 0
I've returned these values from run_sim(), so I'm unsure why it doesn't work
proper glade
you use slots/signals to get return values out of QThreads
set up a variable, set its value to a result inside run, then attach a slot to the qthread's finished signal
finished will be emitted automatically once run is completed
you could also set up your own signal on the qthread and send the result out through the signal itself
wide stump
@proper glade
Give an example
I tried subclassing QThread as I said ```python
class AThread(QtCore.QThread):
def __init__(self, func, *args, **kwargs):
QtCore.QThread.__init__(self, *args, **kwargs)
self.func = func
self.args = args
self.kwargs = kwargs
def run(self):
return self.func(*self.args, **self.kwargs))
That won't work TypeError: invalid result from AThread.run()
I tried connecting the finished signal python t = AThread(self.myfunc, self.myarg); t.start() t.finished.connect(lambda: return t) # That didn't work, How do I return here
wide stump
Dealing with a mainloop is so stupid
wispy oar
Is there perhaps a simpler workaround, or would it be much better to do it this way?
Like, I was considering just saving the values to a list
And then perhaps the values can be loaded from the list
rocky dragon
you transfer the result through a signal
from time import sleep as do_stuff
from PyQt5 import QtCore
class Thread(QtCore.QThread):
result_signal = QtCore.pyqtSignal(str)
def run(self):
do_stuff(0.1)
...
self.result_signal.emit("payload")
app.quit()
app = QtCore.QCoreApplication([])
a = Thread()
a.result_signal.connect(print)
a.start()
app.exec()
or if going through finished, you save it to an instance variable and connect finished to something that handles it with loading the value from that variable
no linking to returns
rocky dragon
They're fundamental for working with qt
it calls the linked callable with what you emit
rocky dragon
because they work within the c++ event loop you must have an app running and a signature with what you emit on creation
yes
wide stump
So this will work then right return self.result_signal.emit("payload")
rocky dragon
no return
just emit and connect that signal to a callable that handles it
run shouldn't return or only return None to stop execution
wide stump
So I just assign that emit method to a variable?
rocky dragon
Am I assigning anything up there to emit?
rocky dragon
you connect it to something that handles what you emit
rocky dragon
yes, a callable. So a func, method or a class with call
wide stump
Ohh nvm

you can call the func you wanted to return, and then emit its result to whatever you wanted to do with what you returned
proper glade
with regards to finished, you have to set up a separate variable somewhere else, set it to something inside run and then use that variable to access the result once finished is emitted
so e.g.
class WorkThread(QThread):
def __init__(self):
super.__init__()
self.result = None
def run(self):
self.result = some_stuff
Then later on:
thread = WorkThread()
thread.finished.connect(lambda: print('Result of work:', thread.result))
@proper glade Yeah dude I think I've tried that
if self.result = a_function and if I wait for thread.result() later on
It'll block the mainloop while waiting
proper glade
that's not what you showed in your snippet.
wide stump
I know I'm sorry I tried a lot of stuff that's why I'm asking here
So if I run it like this ```python
class AThread(QtCore.QThread):
def __init__(self, func, *args, **kwargs):
QtCore.QThread.__init__(self, *args, **kwargs)
self.func = func
self.args = args
self.kwargs = kwargs
def run(self):
self.que = que
self.result = self.func(*self.args, **self.kwargs))
And then call it ```python
thread = AThread()
result = thread.result # I think this'll block the mainloop
But self.result will run that function
proper glade
look at my snippets again, you have to use thread.result inside a callback connected to the finished signal
But self.result will run that function
simply accessing self.result isnt going to run anything
wide stump
Oh okay
How do I get it after that
thread.finished.connect(lambda: print('Result of work:', thread.result))
proper glade
it's right there in thread.result
you can do whatever you want with it there
inside that callable
wide stump
How do I get it out of the callable
Cause if I add python result = thread.result print(result) after that it'll probably print None or something like that
proper glade
something like this, since you can't do assignments inside lambdas
some_value = None
def callback(value):
some_value = value
thread.finished.connect(lambda: callback(thread.result))
not much point to this though
wide stump
Alright that makes sense I guess
proper glade
you might need a global some_value or nonlocal some_value at the top of the callback function
to fix scoping issues
wide stump
Yeah got it thank you

Hi, how can I implement a cellDoubleClicked signal (like the one in QTableWidget), when using a QAbstractTableModel inside a QTableView?
proper glade
@gaunt portal QTableView, by virtue of being a child of QAbstractItemView, has a doubleClicked signal
gaunt portal
Ok, I'm not sure how to send the signal, I'll show some code
proper glade
the signal gets sent automatically
when you double click an item
it's built in
you just gotta connect stuff to it
gaunt portal
def __init__(self, con, cur, students_ui, student_dialog, add_borrow_dialog):
super(Students, self).__init__()
self.table = QTableView()
self.verticalLayout.addWidget(self.table)
self.insert_data(data)
def insert_data(self, data):
self.model = TableModel(data)
self.table.setModel(self.model)```This is the widget that holds the table view
def __init__(self, data):
super(TableModel, self).__init__()
self._data = data
def data(self, index, role):
if role == Qt.DisplayRole:
return self._data[index.row()][index.column()]
def rowCount(self, index):
return len(self._data)
def columnCount(self, index):
if self._data == []:
return 0
return len(self._data[0])```
The table modelYou mean I should send the signal inside the TableModel class, but I want to connect it to a function in the Student class
proper glade
what i mean is you don't have to implement or emit it yourself
gaunt portal
but the callable lives in the Student class, and the signal is sent inside the TableModel class
proper glade
e.g.
self.table.doubleClicked.connect(lambda index: print(index))
gaunt portal
yes, but the scope wil not let me do this
proper glade
the signal is emitted by the treeview, not the model
tableview*
it belongs to the tableview
gaunt portal
class Students(QWidget):
def __init__(self, con, cur, students_ui, student_dialog, add_borrow_dialog):
super(Students, self).__init__()
self.table = QTableView()
self.verticalLayout.addWidget(self.table)
self.insert_data(data)
def insert_data(self, data):
self.model = TableModel(data)
self.table.setModel(self.model)
def open_dialog(self, row, column):
student_id = self.table.item(row, 0)
dlg = StudentDialog(self.con, self.cur, student_id.text(), self.student_dialog, self.add_borrow_dialog)
dlg.exec_()```
So I want to call the open_dialog funcAnd inside the TableModel
def __init__(self, data):
super(TableModel, self).__init__()
self._data = data
self.table.cellDoubleClicked.connect(self.open_dialog)
def data(self, index, role):
if role == Qt.DisplayRole:
return self._data[index.row()][index.column()]
def rowCount(self, index):
return len(self._data)
def columnCount(self, index):
if self._data == []:
return 0
return len(self._data[0])```I would need to do something like this
but the open_dialog func does not belong to the tablemodel
proper glade
why do you need to connect it inside the model
you already have the tableview there in the Students class
open_dialog belongs to the Students class
gaunt portal
Oooh, I got the inheritance wrong
Ok, let me try
Yep, works, I get the index of the cell that I click on
I can't find how to get the data from a given cell, when I know the coordinates, I'm searching the docs for 10 mins
gaunt portal
Ok, and I want to get the data of the first column, no matter where I click on the row, do I need to create another qmodelindex?
proper glade
qtablemodel probably has a method for getting the qmodelindex for a given coord
so yea same row, column 1
imo you should just store the data list in Students
so you can access it directly in the callback
https://doc.qt.io/qt-5/qtableview.html#indexAt there it is
gaunt portal
damn, right
and then I just call .data() for that index
Uh, stuck again
student_id = self.table.indexAt(QPoint(index.row(), 0))
print(student_id.row())
dlg = StudentDialog(self.con, self.cur, student_id.row(), self.student_dialog, self.add_borrow_dialog)
dlg.exec_()```student_id.row() always returns 0
But index.row() will return the row that I clicked on
I'm not sure what's wrong
proper glade
oh right indexAt is asking for literal content coordinates
not grid cell coordinates
https://doc.qt.io/qt-5/qmodelindex.html#siblingAtColumn this might be more useful
@gaunt portal
inland notch
can you change a bool with root.after in tkinter?
gaunt portal
@proper glade , I managed to solve this, by calling self.model.index(cell_index.row(), 0).data for the QTableModel, where cell_index is the cell that I click on
This returned the corect data that I needed
Thanks for the help

proper glade
@gaunt portal if you use https://doc.qt.io/qt-5/qmodelindex.html#siblingAtColumn you can get the model index at column 1 without needing to access the model
gaunt portal
I tried that, but it always returned an Invalid Index (-1,-1)
Maybe I implemented it wrong, idk
But I'm happy that it works with model.index()
gaunt portal

Basically I've set up a grid layout already of my program

Either open an error dialog, which seems more common, but it depends on what you want the workflow to feel like
Dialogs pretty much interrupt the flow

hey, im drawing many (200+) 2D designs. its like a tessellation if youre familiar. they look like grids but each cell updates based on its neighbor
ive used tkinter before, but using it in an object oriented way makes it reallyyyyyy slow. and each cell's state must be saved for the program to update
gaunt portal
woah, that's cool

any suggestions on libraries/graphics engines?

both PyQt5 and kivy are object-oriented

gotcha
and thanks! you can read more at https://www.wolframscience.com/nks/p51--the-search-for-general-features/
the backend is sups simple: you start with an array like [0,0,1...] to represent every cell as dead or alive. then you have a rule, like if a 0 is surrounded by other 0's it stays 0. you make more rules and then you update the array. i just am not sure of how to draw it in python
sullen thunder
Hey JustAndy,
thank you for the previous link about redrawing line graphs. Do you know how to apply it to a pie graph? most of what they have in the tutorial seems to apply. But it doesn't seem to clear the graph.
sudden coral
@round hazel It's being saved in the selection attribute of the popup widget. Your main class has a reference to an instance of that widget in self.exPopup.
So self.exPopup.selection would get you that value.
round hazel
@sudden coral Thanks...but hmm, I'm getting AttributeError: 'searchPopup' object has no attribute 'exPopup' when I try to do something simple like
y = self.exPopup.selection
print(y)
That's supposed to be done in the main class, not the popup widget
It boils down to this ```py
class Main:
def init(self):
self.popup_instance = Popup()
print(self.popup_instance.selected)
class Popup:
def init(self):
self.selected = "hello, world!"
You need to access an attribute via an instance of the class
round hazel
It is in the main class. Here's the updated code: https://github.com/LiquidHamilton/Testing/blob/master/bgglookup.py
Line 113 is where it's called.
Line 169 is the method in the class where it's created.
sudden coral
The error says that searchPopup doesn't have the attribute, which means self is a searchPopup. If it was in the main class it would say Ui_MainWindow 🤔
Oh, you're calling lookup from within the popup class
That's why self is the popup
Why are you doing that?
Do you want that behaviour i.e. for lookup to be called after clicked?
round hazel
Basically, it runs lookup based on a search inquiry. If it finds the result on its own, it runs "lookup" with the ID it found. Otherwise, it creates the popup with search results. If you select a result, it will get an ID that it should pass back into the main class and re-run "lookup" with the selected ID
sudden coral
I feel like using a QDialog would be better suited for this.
Or at least using signals and slots in some way so that your main class knows when the a selection was made
The main class should be responsible for calling the lookup, not the popup window.
So the popup can signal to the main class something was selected and that's it. The popup shouldn't need to know or care what the main window does with that info, as it's not the popup's job to be concerned with that. It's job is to display a list for a user to select a value.
round hazel
I originally was trying to use a qdialog but I didn't think it could have a list widget built into it so I abandoned that idea. It would be easier than a second class.
And I also thought about signals and slots but that's a bit more than I know how to do with PyQt at the moment. I've played around with them but haven't really grasped the whole concept even though it seems simple enough. You're right that either of those two options would be best. If I can figure out signal/slot I think that would work.
sudden coral
QDialog is convenient because it has some signals already built in and your main class could just connect to them
QDialog can have any widgets, including a list.
If you have more questions about it I can try to answer
round hazel
Ok well I appreciate the info you've given. I'll give QDialog a shot and see what I can do with that so I can abandon the second class.
sudden coral
Well it still should be a separate class
The dialogue window would be a separate window from the main window.
round hazel
Oh hmm. I guess I need to go back to the documentation then and try to figure this out. Didn't realize it would be such a daunting task to pass a single int, haha. I've given up on this project multiple times over the past few months because of this very reason.
sudden coral
Indeed I find the topic of inter-widget communication is a struggle for many beginners of the library.
There's probably a lot of bad ways to do it which are simpler 😄
round hazel
At this point, all I need is some simple hack job to make it work. This is really just a personal passion project to learn more about PyQt, and this is my last step to making it functional. What would YOU do in this instance to get that to work?
sudden coral
Me, given my experience, would make a QDialog. In your position, give me a moment to think about it.
But it's worth mentioning that if your goal is to learn PyQt then wouldn't you want to learn how to do things the right way?
QDialog is an opportunity for you to learn something new, if that is what you're after
round hazel
You're right, and I do like learning new techniques. I've just been working on it so long and the end is so close. But, you're right, I'll learn QDialog and try to make it work correctly.
sudden coral
Looking at examples really helped me learn this library. Maybe that a good learning method for you too.
round hazel
That's how I've been doing it. I've been deconstructing examples to learn how they work. That's how I learn best...taking a completed example and breaking it down.
sudden coral
I used QDialogs in this project of mine
It's not super well documented or high quality code cause it was a code jam and I had like a week
A thing to note is that I re-use dialogs rather than re-creating them, so my dialog classes sometimes have extra code to reset their state. You don't have to do it this way. Creating a new dialog is fine too.
round hazel
Hmm, I appreciate the help. I'll see what I can learn from that. One last quick question though. If I create the QDialog from the main class, as a separate method, what is the second class for then? All the other examples I've seen create the dialog within the main class.
sudden coral
You subclass QDialog to customise its UI and behaviour.
round hazel
Ah gotcha.
Wait but then wouldn't I be back to square one of having to send the result from that class back to the main class?
Or does QDialog have a built in signal for that?
sudden coral
Yes and yes
round hazel
Ok perfect. Thanks for all the help! I'll stop bugging you and go read haha
sudden coral
Well sort of, there's not a signal to retrieve a value per se, but there are signals for when the dialog is completed/closed, so you know the user is done choosing and its safe to retrieve the value now.
But there is also this https://doc.qt.io/qt-5/qdialog.html#return-value-modal-dialogs
round hazel
Perfect!
round hazel
One final question. I'm just about there! I've got a QDialog working now, and I have it sending the accept signal, which outputs "1" as it should. How do I change this to send the int value back instead of just "1"? Relevant code:
# from main class
def popup(self, results):
self.popupsearch = searchPopup(results)
self.result = self.popupsearch.exec()
print(self.result)
#from dialog class
def clicked(self, qmodelindex):
self.item = self.listwidget.currentItem()
self.row = self.listwidget.currentRow()
self.selectionindex = self.results[self.row]
self.selection = self.selectionindex.id
self.accept()
I want the accept signal to send the value of self.selection
Scratch that! I figured it out. I used self.done(self.selection)

How to get objects that are animated in kivy?

what do you mean?
there are animations, and there are widgets, and an animation can be applied to some widgets, until it's done
the animation knows which objects it's being applied to, but it's its internal state, i don't think you should rely on it, if you applied the animations to widgets, you should be able to keep track of which

Try to set a break point before the game_input func and run the app step by step in debugging mode, to see what if statement is executed
Does anyone know where to learn basic UI design, or how to make things look better in PyQt5?
digital rose
What break point?
There are 1 if and 2 elifs in the func
and all of them get run
Oh I was wrong
same if is getting run 3 times
fixed it

stupid question but how can I use javascript to code a GUI but not have it open in a webpage but rather like a window with a x minimize and expand button. I want to make the frontend for my python code but don't want to use tkinter to do it
sudden coral
There are other options for GUIs besides tkinter that are in Python
It sounds like you're thinking of Electron but with a Python backend. Maybe that could work but it sounds complicated to me. I'm not a JS dev so what do I know.
Seems like the two languages wouldn't interface well
willow prism
oh its not just as simple as assigning functionality to javascript elements?
sudden coral
No, unless your Python app is like a REST API or something.

Thank you again for the direction to the tutorial. I was able to utilize it to build my desired application. My nested pie graphs due now update upon receiving the proper signal.
I don't think i fully understand why the tutorial creates its own canvas class. I think, what it is doing is turning the Matplotlib canvas into a PyQt5 widget that can be interacted with via the FigureCanvasQTAgg object.

You're welcome @sullen thunder
From what I have seen, matplotlib also uses this approach https://matplotlib.org/gallery/user_interfaces/embedding_in_qt5_sgskip.html
From learnpyqt :
Plots from Matplotlib displayed in PyQt5 are actually rendered as simple (bitmap) images by the Agg backend. The FigureCanvasQTAgg class wraps this backend and displays the resulting image on a Qt widget. The effect of this architecture is that Qt is unaware of the positions of lines and other plot elements — only the x, y coordinates of any clicks and mouse movements over the widget.
So Qt(pyqt5) interprets the FigureCanvasQTAgg as a image
Which you can apply simple qt func on, OR use the functions provided by Matplotlib

Tkinter is useful, but the documentation can be hard to find

<input ng-keyup="$event.keyCode === $ctrl.keyCodes.enter && $ctrl.getMember($ctrl.keyword)" ng-model="$ctrl.keyword" class="form-control input-field ng-valid ng-valid-maxlength ng-dirty ng-valid-parse ng-touched ng-empty" type="text" placeholder="Search Members" maxlength="120">
how do i get the element of this?

@willow prism you can use pyqt5/pyside2 webengine and communicate front and back ends using webchannels. I’ve done a project using that architecture

Can I use modules inside a function?
Because I used one inside a function and it's not working instead it's giving me an exception.

!e ```py
def num():
import random
return random.randint(0,10)
num()
Sorry, but you may only use this command within #bot-commands.

tldr; yes u can
digital rose
I mean if that module wasn't mentioned inside a function but outside of it.
Will it still work?

ofc

Hey i wanna make this

WHat would be a good canvas? I tried using p5 its very buggy
latent mortar
I did it with Pygame :P

Could you use module 'requests' in a GUI?
Because 'requests' gets a specific information from the chosen API.
And I think GUI can't interact with Internet connection, can they?
sudden coral
GUIs can interact with the internet
Yes, requests module can be used in a GUI.
Though you may want it in a separate thread so long requests don't seize your application.

I think the best python canvas is probably QGraphicsView in pyqt5

i must say kivy has a very powerful canvas too, it's basically opengl, but in easy mode

opengl and easy are two words that often shouldn't live together lol

@bitter merlin can it make live animations like those ^?

There are lines and circles in my py game
and i want all the lines to be above the circles
like no pixel of circle should be seen over a line
how will i be doing this?
in simple terms
i want no circle to overlap a line
like if lines and circles overlap i want line to be seen
latent mortar
ping me if you answer
elfin stirrup
@latent mortar what library
latent mortar
PyGame @elfin stirrup
elfin stirrup
ok

@latent mortar not the proper parameters, and code is a bit quick and dirty, but just to give you an idea https://gist.github.com/8b9f989101f20045f04aafe583403401
obtuse thistle
just keep the lines and circles in different groups
with the graph program i'm working on, i keep node and edge instructions separate like this:
self._edge_instructions = CanvasBase()
with self._edge_instructions:
self.edges = {edge: Edge(edge, self) for edge in self.G.edges()}
self.canvas.add(self._edge_instructions)
self._node_instructions = CanvasBase()
with self._node_instructions:
self._source_color = Color(*SOURCE_COLOR)
self._source_circle = Line(width=SOURCE_WIDTH)
self.nodes = {vertex: Node(vertex, self) for vertex in self.G.vertices()}
self.canvas.add(self._node_instructions)
