Yeah of course

[digital rose]

Can you give me an example with my upgrade button

and then explain it

[static cove]

Uhhh sure, let me get to my computer

[digital rose]

okay

brb

My code is above if you wanna do it I'll be back gotta do something

ok back

[static cove]

Okay, I'll post a shortened snippet, just so it's easier to see what's going on

[digital rose]

ok

rn I'm trying to figure out how to make a thing that will show your money

the issue is it just doesn't update

current_money = Label(
    text = f"You currently have {money}$",
    fg = "green",
    bg = "black"
    )```

[static cove]

from tkinter import *

# Screen
screen = Tk()
screen.title("You have $")
screen.geometry("500x500")

welcome_text = Label(text="Welcome to Money Simulator")

welcome_text.grid(row=0, column=1, columnspan=2, sticky='')

# We're going to weight the unused columns so that things are centered.
# If a column is used, we should weight it.
screen.grid_columnconfigure(0, weight=1)
screen.grid_columnconfigure(3, weight=1)

# Money
click_me = Button(text="Button 1")
click_me.grid(row=10, column=1)

# Upgrades
upgrades = Button(text="Button 2")
upgrades.grid(row=10, column=2)

# We need to weight the rest of the rows
for _ in range(10):
    screen.grid_rowconfigure(_, weight=1)

screen.mainloop()

[digital rose]

thanks

I have a question

[static cove]

So the big thing is that I have 4 columns: 0, 1, 2, 3.
For the two buttons, I want space on either side, so I have to have 2 columns on either side. 2 buttons, 2 columns on the ends = 4 total columns.

With 4 columns, I still need to center that top text. To make it simple, I just make it take up two columns: 1 and 2

[digital rose]

Is there a way to make vsc do what idle does

because I have to use idle because vsc doesn't open the boxes

[static cove]

hmmm... let me test it in VSC

[digital rose]

ok

[static cove]

What boxes is it supposed to open?

[digital rose]

the tkinter one

so you can play

[static cove]

hmmm, it's opening up for me. Let me check something

[digital rose]

ok

[static cove]

Okay weird, it's opening up tkinter for me

If you open the terminal in VSC, and type the py yourfile.py or python yourfile.py does it work then?

[digital rose]

I relaunched vsc and it works now

thanks

[hoary cypress]

just make sure the path is specified to your file

[static cove]

So! To get a Label or another widget to update based on a variable, you want to use a special tkinter class, called StringVar

[digital rose]

example?

[static cove]

typing up one now~

[digital rose]

okk

[static cove]

from tkinter import *

money = 5
earnings = 1

# Button 1 Earnings
def money_button():
    global money
    global earnings
    money += earnings
    money_display.set(f"You have ${money}")
    print(f"You now have {money}")

def upgrade_button():
    global money
    global earnings
    

# Screen
screen = Tk()
screen.title("You have $")
screen.geometry("500x500")

# We're going to use a StringVar to have a variable we can update
money_display = StringVar()
money_display.set(f"You have ${money}")

welcome_text = Label(text="Welcome to Money Simulator")

welcome_text.grid(row=0, column=1, columnspan=2, sticky='')

# We're going to weight the unused columns so that things are centered.
# If a column is used, we should not weight it.
screen.grid_columnconfigure(0, weight=1)
screen.grid_columnconfigure(3, weight=1)

money_var = StringVar()

# Money
click_me = Button(text="Button 1", textvariable=money_display, command = money_button)
click_me.grid(row=10, column=1)

# Upgrades
upgrades = Button(text="Button 2")
upgrades.grid(row=10, column=2)

# We need to weight the rest of the rows
for _ in range(10):
    screen.grid_rowconfigure(_, weight=1)

screen.mainloop()

Take a look at that and let me know if you have questions about how it's put together

Normally I'd try to guide you to figure it out on your own, but this is more of lack of knowledge of a library, so I think it's better for me to show you how to do things and what's even available

[digital rose]

okay

working on changing some things of it right now

thank you

[static cove]

happy to help~ Feel free to ping if you have any questions or hit some blocks

[digital rose]

okay

ty

I will message you some time about how to publish this on the play store

[static cove]

That is not something I know much about unfortunately

[digital rose]

okay

I started back from what I had because It got messy

I'm gonna read what you sent and figure it out

thanks

@static cove py current_money.grid(row=0, column=1, columnspan=2, sticky='') AttributeError: 'StringVar' object has no attribute 'grid'

I'm getting this error

[static cove]

So a StringVar is used in a Label, not in the grid itself

[digital rose]

current_money = StringVar()
current_money.set(f"You currently have {money}$")
current_money.grid(row=0, column=1, columnspan=2, sticky='')
``` How do I fix this then

[static cove]

Sooo it would be:

money_var = StringVar()
money_label = Label(textvariable=money_var)
money_label.grid(row=0, column=1, columnspan=2)

[digital rose]

erm

can you add it to my code

@static cove

[tawdry mulch]

Not really? There is a config method too

[digital rose]

coolcloud

[tawdry mulch]

yes?

[digital rose]

can you do it for me

[tawdry mulch]

What is your code

[digital rose]

current_money = StringVar()
current_money.set(f"You currently have {money}$")
current_money.grid(row=0, column=1, columnspan=2, sticky='')```

Says I can't use grid with stringvar

brb

[tawdry mulch]

@digital rose This should work

[digital rose]

I don't understand where I would put my stuff though

could you add the required thing to mine

[tawdry mulch]

Where is your code

[digital rose]

I sent it

[tawdry mulch]

Can you please send again

[digital rose]

current_money = StringVar()
current_money.set(f"You currently have {money}$")
current_money.grid(row=0, column=1, columnspan=2, sticky='')```

[tawdry mulch]

Do you have a label

[digital rose]

no

That's my code

It just doesn't work because StringVar doesn't have grid

[tawdry mulch]

StringVar is not a widget so they cannot be grid. They must be associated to a widget.

[digital rose]

okay so what would I do

[tawdry mulch]

You should be asking that to your self, I do not know what you want. Usually people want a label, prolly you too

[digital rose]

what the fuck

[tawdry mulch]

what

[digital rose]

what do I do

@jade crane why did you spam ping @languid notch

[tawdry mulch]

You can create a label and associate it with this stringvar

[digital rose]

how though

it's gonna change what it is

that's what I'm not understanding

I know the problem just not what to do

[tawdry mulch]

I think you should explain what all you have so far

[digital rose]

current_money = StringVar()
current_money.set(f"You currently have {money}$")
current_money.grid(row=0, column=1, columnspan=2, sticky='')```

This is what I have

Tab? you mean the title bar?

Can someone tell me how exactly to load PyQt5-based custom widget plugins to Qt Designer? tutorials are trash, I made the plugin but I don't know how to load it.
PLEASE HELP

It's better to do it in Qt Designer,
First design your own title bar in Designer (Add a label as an alt to title name and three buttons of your own for "Close" "Maximize" "Minimize") and in Python do as bellow to remove the default title bar:
in imports add:
from PyQt5.QtCore import Qt
then in your window class:
self.setFlag(Qt.FramelessWindowHint)

why doesnt that work?

[cursive basin]

what doesnt works?

Someone here to help me with PyQt?

I have this issue:
I created a GUI with QtDesigner and i added 2 textfields. Now i want to get the Input. As far as i know this is how it works:

self.user_input_field = QtWidgets.QLineEdit()

@pyqtSlot()
def getWrittenInput(self):
  input_textbox = self.user_input_field.text()
  return input_textbox

When i call this function from another file with this command:

print(user_input)```
The window will crash and this is the error:
```Process finished with exit code-1073740791 (0xC0000409)

On Stackoverflow a solution is to install PyQt but i already did so idk why this error shows up.

@static cove Hello! You had asked me to ping you in this channel for more resources regarding gui theory

Sorry I took a little too long

[urban garden]

Do someone can help me?

[digital rose]

can anybody help me with Qt designer?

@urban garden can you help me?

[urban garden]

@digital rose
Maybe.. whats your question?
(I'm new to Qt Designer)

[digital rose]

hey, So the problem im getting is i've added a background-image to the QmainWindow and now whenever i add any label or anything, it copies the background image of the qmainWindow.

even if i add frame of widget instead of label those also copies/inherits the image of QmainWindow which doesn't make sense and it should not do that,

[urban garden]

try to add a background color to the stylesheet of the lables/...

[digital rose]

ive tried it

[urban garden]

because with no backgroudn color it could be transparent

[digital rose]

let me send you a screenshot

[urban garden]

kk

[digital rose]

do you know anyother method of adding a background image ? maybe i can try that

[urban garden]

ok lemme do some research

[digital rose]

ok

[urban garden]

i tried to recreate your problem but when i try to add a background image it does not even show up. wtf

[digital rose]

You need to add the resources first

[urban garden]

yes but i my image is a .png and not .qrc and then i cannot add it

[digital rose]

You can add it,

[urban garden]

oh ok. let me try

now it works

[digital rose]

Yup, so recreate the problem by adding the background image to QmainWindow or Qcentral widget and then add anything (label frame etc)

hey dude, thanks for your time really appreciate people like you who spends their time to help others, I just found the solution by adding a completely transparent image to the background of the label

[urban garden]

@digital rose
yeah i also figuered out that if you add another background image to the label it covers the the "main background-image". But i think this cannot be the best solution (i think the programm could work slower because it has to load all the images but i have no knowledge about such things it just sound logical). It's weird that the background-color of the label isn't "superior" even if you bring it to the front. idk what's the issue there but i'm happy you found a way around.

[digital rose]

yeah, it's not an ideal solution but it works, and yes it will cause the application to load a bit slower but where it's going to be used, those 500ms doesn't matter, so i will go ahead with this, If you found the actual solution anytime, Please message me, i would really appreciate it, Thanks again

Is it possible to auto resize Widgets with this kinda layout. I prototyped the application with cordinats for now.
Like having not everything centered.

I wasnt able to find a layout that fids these special needs bzw. how i placed them

[plush stream]

@mystic crescent make a hybrid layout by combining more than one layout

[mystic crescent]

Oh,right! Thanks
What is the setting to set those layouts to autoresize?

For the bike logo, username text field, password field, and login button use QVBoxLayout

You can get creative with the other widgets

[digital rose]

i have a quick question related to PYQT5
How can i use the QPushButton as a holding button?
So like i want a function to be only executed while the button is pressed

@plush stream can you please help me?

[static cove]

So you could have the function essentially be a while btn.isDown(). isDown is a property available for any of the buttons

The clicked could start the function and it'll only run while that's true

[digital rose]

Thanks for the reply, i did it like this and it only prints the string "reached"

i connected the QpushButton to this "test_test(self)" method using this line

self.home_ui.key_2.mousePressEvent = self.test_test

@static cove

[static cove]

can you print event for me?

[digital rose]

        print("reached")
        print(event)
        state = self.home_ui.key_2.isDown()
        while state:
            print("yesss")
            state = self.home_ui.key_2.isDown()```

[static cove]

key_2 is your QPuishButton?

[digital rose]

yes

[static cove]

Why don't you use the signal pressed instead of mousePressEvent?

[digital rose]

Ok, let me try that

here's how to code looks now But it prints out the "yesss" infinitely and make the UI unresponsive

[static cove]

You want other aspects of the UI to update while the button is being pressed down?

[digital rose]

not really, it's ok if they don't update while the button is pressed, but atleast the button should be responsive and should stop when i release the mouse button

it amazes me that despite QT being such a big platform lacks these simple functionalities, i've read the whole documentation now and found nothing to accomplish this task

[sudden dock]

you know how there are like drop down lists everywhere and stuff? is there like some sort of plugin to do that with python code? my code has tons of blocks and in one section a gajillion tons of if statements but trying to scroll to find the one im looking for takes ages, if there is some way to like toggle it to hide its block...idk is there a plugin or mod for that

[static cove]

So if you want something to have in the background, but still have other parts of the GUI be responsive, you need to use threading

That's just the basics of working with GUIs

[digital rose]

Yes i'm pretty familiar with multithreading and Qthreads But i don't want anything to happen in the Background i just want it to print "yesss" while the button is pressed and stop when the button is released

[digital rose]

Right now with this code, it does print "yesss" when i press the button but it never stops, it just infinitely prints that out,

[static cove]

Basic example using QThread:

from Pyside6 import QtCore, QtWidgets
from __feature__ import snake_case, true_property

class Worker(QtCore.QObject):
  def __init__(self):
    super().__init__()
    self.keep_going = True
  
  def test(self):
    self.keep_going = True
    while self.keep_going:
      print("hi?")

class MainWindow(QtWidgets.QWidget):
  def __init__():
    super().__init__()
    self.layout = QtWidgets.QHBoxLayout(self)
    
    self.thread = QtCore.QThread()
    self.worker = Worker()
    self.worker.move_to_thread(self.thread)

    self.btn = QtWidgets.QPushButton("Press Me", pressed=self.worker.test)
    self.btn.released.connect(self.pls_stop)

    self.layout.add_widget(self.btn)
    self.thread.start()

  def pls_stop(self):
    self.worker.keep_going = False
    print("stopped")

# Insert basic app start stuff here

[static cove]

so that's you wanting it to do something while the GUI is doing something else. You need a thread for that.

[digital rose]

Okay, thank you,

[digital rose]

does anybody know something better than tkinter cause i want to make a pretty simple UI but cant find what im looking for

[lime monolith]

https://docs.python.org/3/library/othergui.html

[clever raptor]

Hello everyone! I'm still a beginner and I want to develop a desktop application so I don't know which package I should use, any recommendations?

[static cove]

Check the channel description! Some good libraries mentioned there

[zealous abyss]

if anyone is familiar with curses and py2exe, i have a question about it in #help-cake if you'd like to check it out

[thorny star]

from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *

class MainWindow(QMainWindow):
    
    def __init__(self, *args, **kwargs):
        
        super().__init__(*args,**kwargs)
        self.setWindowTitle('Test')
        
        widget = QPushButton('Test Once Again')
        widget.setCheckable(True)
        self.setCentralWidget(widget)
        self.toggleState = True
        
        
        widget.clicked.connect(self.buttonClicked)
        widget.clicked.connect(self.buttonToggled)
        widget.released.connect(self.buttonRelease)
        widget.setChecked(self.toggleState)
        
        
    def buttonClicked(self):
        print("Pressed")
        
    
    def buttonToggled(self, check):
        print(f'Toggled! Set to {check}! \n\n')
        self.toggleState = check
        print(self.toggleState)
        
    
    def buttonRelease(self):
        
        self.buttonRelease = self.widget.isChecked()
    
    
app = QApplication([])
window = MainWindow()
window.show()


app.exec_()```


Why is it that when I run this , it spits an error stating that widget isnt an attribute of self when buttonRelease() is run?

Is it not very clearly defined in widget = QPushButton('Test Once Again')

[royal gull]

Well, it is, however, it's just defined as a simple variable which will be gone by the time the constructor is done with it's tasks, so you would want to make widget an actual instance attribute by prefixing it wiht self. when declaring it (and using it) in the constructor (__init__)

[thorny star]

wait so just widget is a standard variable that cant be used in buttonRelease() because its only in the scope of the __init__?

[royal gull]

Yes

[thorny star]

Thank you!

sorry to asjk again

ive hit another roadblock

from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *

class MainWindow(QMainWindow):
    
    def __init__(self, *args, **kwargs):
        
        super().__init__(*args,**kwargs)
        self.setWindowTitle('Test')
        self.widget = QPushButton('Test Once Again')
        self.widget.setCheckable(True)
        self.setCentralWidget(self.widget)
        self.toggleState = True
        self.buttonReleased = True
        

        self.widget.clicked.connect(self.buttonToggled)
        
        self.widget.setChecked(self.toggleState)
        
        
    def buttonClicked(self):
        print("Pressed")
        
    
    def buttonToggled(self, check):
        print(f'Toggled! Set to {check}!')
        self.toggleState = check
        self.setWindowTitle('Changed!')
        self.widget.setText('I have been clicked once already now')
        self.widget.setEnabled(False)
        
        self.widget.setText('I am back!')
        self.widget.setEnabled(True)
        self.widget.clicked.connect(self.buttonToggled)
    
app = QApplication([])
window = MainWindow()
window.show()


app.exec_()

If I hit the button once, it gets disabled and subsequently enabled again. Howeber it runs print(f'Toggled! Set to {check}!') more and more times with each click

In the first click print(f'Toggled! Set to {check}!') happens once

in the 2nd click it happens twice

and this number keeps increasing

is there a specific reason as to why this happens?

[tawdry mulch]

I think it is called context menu

[lime sapphire]

hey, quick question, is there a way to make a listbox item have a selected background without me clicking it? (lets say with a function on a button click)

nevermind figured it out

[digital rose]

I have a question about Tables in Rich. I'm currently adding rows my_table.add_row(last_seen, name) and they appear under the previous line. Is there a way to get all the rows currently in the table to order them differently, aka the equivalent of a table.get_rows() ?

[pseudo folio]

I am trying to draw a line with a text label on it in pyqt. Is there something already in QtWidgets.QGraphicsLineItem() that I can use. If not, can I use an item group?

[hasty sable]

(Kivy)

uhhhh i have this errror where if i right click on my Text iput, a red dot will appear? wat is this ( sorry for the gramar)
i also have a screen record

[tribal path]

Those are emulated presses for multiple fingers, can remove via config

[restive mountain]

how to store text in textboxes in tkinter

[neat trout]

U mean Store text in variables

From the textbox

[restive mountain]

yes

[neat trout]

text = Textbox.get()```

Try maybe

[restive mountain]

ok

[tawdry mulch]

This isnt Entry.

[restive mountain]

its nowtworking

[neat trout]

Oh sorry its actually Entry and not text before those parentheses

My bad

[tawdry mulch]

What?

[restive mountain]

?

[neat trout]

text = Textbox.get()```

[restive mountain]

ok

[tawdry mulch]

Bro, this isnt tkinter...?

[restive mountain]

;

[neat trout]

It is.

[restive mountain]

    newwindow = Tk()
    newwindow.geometry("400x450")
    newwindow.title("register new passcode")
    a = Entry(root, text="name")
    usrnm = a.get()
    b = Entry(root, text="password")
    pwd = b.get()
    c = Entry(root, text="website")
    web = c.get()
    myButton = Button(root, text="save", command=save)```

[tawdry mulch]

That? No way

[restive mountain]

is something wrong here

[tawdry mulch]

Yes, usrnm is ''

You are fetching the value as soon as the box is created, hence it is empty

Read about event driven programming

[restive mountain]

    newwindow = Tk()
    newwindow.geometry("400x450")
    newwindow.title("register new passcode")
    a = Entry(root, text="name")
    "usrnm" = a.get()
    b = Entry(root, text="password")
    "pwd" = b.get()
    c = Entry(root, text="website")
    "web" = c.get()
    myButton = Button(root, text="save", command=save)```

[restive mountain]

here

[neat trout]

He asked about how to store the value from a textbox in a variable

[restive mountain]

Textbox = Entry(root, colum= whatever, row=whatever)?

[neat trout]

Dont mind the whatever part

[tawdry mulch]

What you are doing is wrong, you cannot assign to a string. What I meant was, you are creating an entry widget and soon after that you are storing the value inside usrnm but there is nothing in the entry box, so it is empty. What you need to do is, create a function to store these into variables

[tawdry mulch]

Still the code given was wrong, there are no arguments colum or row for Entry widget.

[neat trout]

Sorry i forgot.

Its been long since i used tkinter

[tawdry mulch]

Ah its fine, appreciate the effort

[restive mountain]

def save():
usrm = a.get()
pwd = b.get()
web = c.get()

i claimd chat #help mango

[tawdry mulch]

that was unnecessary, anyway carry on

[restive mountain]

def save():
usrm = a.get()
pwd = b.get()
web = c.get()

[tawdry mulch]

looks fine

root.mainloop()

there is something wronge here

error unresolved reference

[tawdry mulch]

a,b,c is created inside newwindow and save does not know it exists, so you should say global a,b,c inside newwindow.

[restive mountain]

global variable?

[tawdry mulch]

2nd of all your a,b,c is not shown into the screen

[tawdry mulch]

yes

[tawdry mulch]

third of all, newwindow = Tk() should be newwindow = Toplevel()

[tawdry mulch]

I told you what to do.

[restive mountain]

currently editing

def save():
global a,b,c
usrm = a.get()
pwd = b.get()
web = c.get()

[tawdry mulch]

No, inside newwindow

Bro why is your window and function name same

[neat trout]

Anyways why use python for UI s?

[restive mountain]

is that problem

[tawdry mulch]

in the future, maybe

[restive mountain]

    global a, b, c
    newwindow = Toplevel()
    newwindow.geometry("400x450")
    newwindow.title("register new passcode")
    a = Entry(root, text="name")
    a.get()
    b = Entry(root, text="password")
    b.get()
    c = Entry(root, text="website")
    c.get()
    myButton = Button(root, text="save", command=save)```

here its it ok @tawdry mulch

[tawdry mulch]

seems fine, run and check

But as I said, you are not putting those widgets onto the screen

[restive mountain]

Entry.place(x=20,y=0)?

@tawdry mulch

[tawdry mulch]

Bro, a.place(x=20,y=0) bla bla

[restive mountain]

it put it on win1 on on win2?

[tawdry mulch]

Whereever it is created

[restive mountain]

root

i replace root with newwindow?

[tawdry mulch]

Bro you know what, do a proper tkinter tutorial, they will explain everything. Slowly move and make progress

[restive mountain]

link?

[tawdry mulch]

Otherwise it will be very hard for you

Watch more videos and practice?

[restive mountain]

ok

bye

myLabel = Label(newwindow, Text="Password")
myLabel.place(x=125, y=80) is this command wrong

[hasty sable]

How to remove :< (just had a pretty bad day thanx to my irl frends, all hail discord)

[hasty sable]

this guy... i learned tkinter from him. but @restive mountain i suggest u use kivy as soon as you learn tkinter(1-2months) and Object Oriented Progremming(1-2 years) it has a much more modern look compared to tkinter. but learn tkinter first as it is base upon which u build others:
Kivy / Other things
Object Oriented Programming(OOPS)
Tkinter
Python base

You should go like this from bottom to top. also i suggest this book Tkinter GUI Application Development Cookbook if u r serious on it.

[tawdry mulch]

On a regular day, I wouldn't recommend learning from him. Does not explain the "concepts" and has some bad coding practices taught there too.

[hasty sable]

yes i agree

but we need python base then gui

if python base is not clear u cant

also if anyone wants to know how to pckage python tell. also how can i use buildozer in windows

[hasty sable]

he teaches just the basics

[tawdry mulch]

I mean if you are looking to build on GUI(as a dev), then no more python.

[hasty sable]

yes

but java to comppli

[tawdry mulch]

I remember I had to spent hours, not knowing what the issue was when the issue was with him not explaining properly

[hasty sable]

yes

also the Great thing bout kivy is

in there website it explains

everything

[tawdry mulch]

ah good documentation is important

[hasty sable]

also try making a new .py and run this one line of code: import this just copy and paste

[tawdry mulch]

Yea I know this

its mentioned in the PEP ones

[hasty sable]

what is it.

yes

The zen of Python

[tawdry mulch]

hmmm yea

[hasty sable]

noice

Why this ain't workin' bois and galis:

window = Tk()
window.title('password')

abc = Entry(window)
abc.pack()

def passcode():
    if abc == 'hello_boi':
        Label(window, text='Hewwo boi').pack()
    else:
        Label(window, text='byeu bowii').pack()

bcd = Button(window, text='sumbimit boi', command=passcode)
bcd.pack()

window.mainloop()```

[young yoke]

abc is an Entry widget, not a string so it will never be equal to "hello_boi" thus if abc == 'hello_boi' will always be false

try if abc.get() == 'hello_boi'

the get() function returns the value of an entry widget (i am not 100% sure though because I haven't used tkinter in a while)

[digital rose]

I have a List I would like to display in the CLI, but every time I do prints the screen flickers (I'm on a RPI3b+). Is there a better way to display tables on screen without calling print() every 1 second? I'm trying to display real time data in the CLI

I tried the Rich library but I can't manipulate the data grid, it's more of a stylistic UI framework

[obtuse thistle]

instead of clearing the screen, use \r to return the cursor to beginning of line

In [32]: print("hello\rhi")
hillo

Can anyone explain what exactly an event handler in PYQT5 is ? Ive read up the docs on QT's website but Im left thoroughly confused

Is it like a slot?

can someone, help me i just finished my login page using tkinter now i want to link it to my main exe file so when ever i run the exe it runs the login page

[kind parrot]

from tkinter import *

btn = Button(interface, text='Calcular', command=dados).place(x=10, y=270, width=100, height=20)

interface.mainloop()

How do I import a math function into python and print it on this interface?

[digital rose]

what math function do you want to import ?

like what are you trying to print?

you can just put
import math at the start of your code

[hasty sable]

@young yoke thanksssss boi

[hasty sable]

Also which is the best module thingy for gui. THe most modern, clean and prefferably simple

[restive mountain]

file.write(username)
file.write(hot)
file.write(het)

[glacial elbow]

hey folks
how can I upload the files to variables and create a generate button?
appreciate the help 🙂

I need create a GUI that upload two images save them in variables and after that we can click on generate button and my code will continue ..

[tawdry mulch]

You can save anything to variables by assigning it to them, var = 'WhateverFileObject'

[rotund reef]

hi - I am looking at setting up a keyboard combination in an application I am making, and was looking at using pynput to handle it. However, I would like to define the shortcut key in a config file, and then set the shortcut at run time based on the values in the config file. i have a variable for the string from the config file for a given key called skey , but if I try to use shortcut = pynput.keyboard.Key.skey I get an attributeerror - in this case, the value of skey = ctrl. How can i make this work ?

[tawdry mulch]

Need to see how you are getting the file

[hasty sable]

ohh

[rotund reef]

in this case, I am pulling in the data from a yaml file . Getting to the values in the yaml is not an issue for me, it is getting the string 'ctrl' to be added to a key combination for pynput

[tawdry mulch]

Any specific reason you chose yaml?

[rotund reef]

mostly for ease of reading the file for humans and it lets me structure stuff in a way that I like

[tawdry mulch]

Anyway show the code please, is ctrl coming out as a string?

[rotund reef]

here is what my code looks like so far
`def usekeys(keyconfig):
numkeys = keyconfig.get("numkeys")
keyiter = 0

while keyiter < numkeys:
    keyiter+= 1 
    sley = keyconfig.get(keyiter) 
    keyinput = pynput.keyboard.Key.skey`

[tawdry mulch]

What is the error

[rotund reef]

When I am running this in the debugger, skey= 'ctrl'
and the error I get is
Exception has occurred: AttributeError skey

[tawdry mulch]

How would you set the key normally?

[rotund reef]

keyComb = {pynput.keyboard.Key.ctrl, pynput.keyboard.Key.alt, pynput.keyboard.KeyCode(char='w')}

[tawdry mulch]

Will pynput.keyboard.KeyCode(char='ctrl') work?

[rotund reef]

no, it only accepts 1 character or a number

[tawdry mulch]

Idk pynput, so is there any other way to set keys? Other than these

[rotund reef]

found a place that has key code mappings - that lets me use keycode(105) for ctrl

[tawdry mulch]

There are plenty of ways that come to my mind, like you can check if the key is ctrl and then Insert 105 or you can Create a dictionary and map Ctrl to 105.

Is there any reason you use pynput and not keyboard

[rotund reef]

mostly because everything I saw for setting up a listener for a keyboard shortcut was based on pynput - I am building something that will be running in the background an always listening for a keyboard shortcut

[tawdry mulch]

Mmmmm, what all keys are allowed, just Ctrl?

[rotund reef]

so the idea is to allow any arbitrary combination of keys - so in my earlier example I was looking at ctrl+alt+w

[tawdry mulch]

Mmmm out of ideas for now, and I gtg. I'll take a look when I'm back

Read through pynput documentation for ways to set keys and you might get something

[tawdry mulch]

Then what's the use of yaml file?

[lavish kindle]

can someone, Help me i have this, exe and i wanted to extend it, I wanted to add a log so for when ever, someone open's it it give's me the time and date or there login and i have no clue how to do that

[rotund reef]

The idea is to allow the end user to define what they want as the keyboard shortcuts there instead of having them hardcoded. There is a value for the number of keys, and then you define the keys
numkeys: 3
1: ctrl
2: alt
3: w

[tawdry mulch]

And what happens when the click this

[rotund reef]

so the idea is that when they enter that keyboard shortcut, it triggers a bunch of other code to run . In this case , it pops up a tkinter entry box where they can enter a number , then when they press enter, that box closes , and more code is called - I am working on a grid snapping tool for moving windows to a specific location on the current screen .

I am using 2 yaml files , 1 called grids.yml, one called layouts.yml . The grids.yml is for defining how many rows & columns you want to use for the layouts .
`

Grids:
12x12:
Rows: 12
Columns: 12
5x5:
Rows: 5
Columns: 5`

In layouts.yml, you define the following:
Which grid you use
The Top Position( in grid squares)
The Left Position ( in grid squares)
The height( in grid squares)
The Width ( in grid squares)
Example :
--- Layouts: "1": Grid: 12x12 TopPos: 0 LeftPos: 0 Height: 6 Width: 6 "2": Grid: 12x12 TopPos: 0 LeftPos: 6 Height: 6 Width: 6

The idea is to make it so that instead of having resolution specific mappings, it is based on your grid squares . Then , when you enter the number from the layouts into the popup when you hit the main keyboard shortcut, it moves the window to that positions and resizes it .

[tawdry mulch]

So the inputs(shortcuts) are basically expected to be inputted within the tkinter window right

.ie, while the window has focus

[rotund reef]

so the key combination(ctrl+alt+w for example ) will be entered when you have any window active , then the tkinter box will appear for you to enter the layout number and press enter (which will close the tkinter entry ) , and then the window you had active will be moved to thelocation defined by the layout

[tawdry mulch]

"...will be entered when you have any window active....": you mean any tkinter created window?

[rotund reef]

no - thats why I was using pynput - because I can have a listener in the background . I am using Xlib to get the active window ID, and xlib to move the window- so you could use it on firefox, vs code, discord, etc...

[tawdry mulch]

Ah kay, you could use keyboard too

import tkinter as tk
import keyboard

def output(lines = 'hehehehe'):
    print(lines)

root = tk.Tk()

button = tk.Button(root, text ='HAHAHA', command = lambda:output('hahaha'))
button.pack()

keyboard.add_hotkey('ctrl+alt+w', output, args=('asdasd',))

root.mainloop()

Look at this example

As simple as this to trigger a bunch of keys

[rotund reef]

interesting.. and that hotkey will be picked up by the application even if it does not have focus?

[tawdry mulch]

def usekeys(keyconfig): 
    numkeys = keyconfig.get("numkeys")
    keyiter = 0
    lst = []

    while keyiter < numkeys:
        keyiter += 1 
        sley = keyconfig.get(keyiter) 
        lst.append(sley)
    keyboard.add_hotkey('+'.join(lst), whatever_func_to_run)

Something like this might work with you

[tawdry mulch]

yep

[rotund reef]

Thanks

[regal heron]

Hello !
I'm using PyQt6 and a QTableWidget to show data (a list of list containing integers) to the user. To populate the QTableWidget I iterate over every row and column and use the .setItem() method which take the row, the column and a QTableWigetItem object. However, when I then show the application the table is empty.
Also, if I use the .item(row,column) method which returns the QTableWidgetItem stored in that cell I instead get a NoneType object.
Any idea what I did wrong ?
Here is the exact method I use :

    def setupTable(self):
        data = self.db.get_data()  # returns a list of lists like [[45,36],[88,99]]
        row_count = len(data)
        column_count = len(data[0])
        self.Table.setRowCount(row_count)
        self.Table.setColumnCount(column_count)
        for i in range(0, row_count):
            for j in range(0, column_count):
                item = QTableWidgetItem(data[i][j])
                self.Table.setItem(row_count, column_count, item)

[tawdry mulch]

Try referring to this: https://github.com/nihaalnz/PassLost/blob/main/main/main.py#L187-L198

[proven basin]

main/main.py lines 187 to 198

def refresh_table(self):
    con = sqlite3.connect(self.filepath)
    c = con.cursor()
    c.execute('SELECT username,url FROM {}'.format(self.file))
    res = c.fetchall()

    for row_count,row_data in enumerate(res):
        self.ui.table.insertRow(row_count)
        for column_number, data in enumerate(row_data):
            self.ui.table.setItem(row_count,column_number,QTableWidgetItem(str(data)))

    self.ui.table.setRowCount(len(res))```

[tawdry mulch]

for i in range(0, row_count):
    self.Table.insertRow(i)
    for j in range(0, column_count):
        item = QTableWidgetItem(data[i][j])
        self.Table.setItem(row_count, column_count, item)

Might work for you

[regal heron]

With this I still get a table with no value in it but it also only have 1 colum while the data for my test is 4 rows and 3 columns

[tawdry mulch]

might be because you are not getting correct data? Try printing it

[regal heron]

No the data is fine it's just testing values : [[88, 88, 100], [88, 66, 82], [36, 63, 60], [31, 65, 34]] , row_count == 4, column count == 3. There is only 1 column because no column is ever inserted .insertColumn(j) for exemple

But thanks for trying to help

[wary gulch]

okay so when i start, My exe the exe and the login form start's at the same time and pops up next, to each other what i'm trying to say is i want the login form to start first then after i login then the main program will then load

how would i do that can someone help me

[buoyant fulcrum]

what part of the code opens up both?

I've never coded/made exe's, but wouldn't you just be able to call the 2nd file from the 1st one?

[regal heron]

what do you use for your gui ? tkinter ?

[wary gulch]

@regal heronyes

[regal heron]

I don't know tkinter but you probably made a class for your login window and another for your main window. When the program start you create a login object and only when it returns a correct flag instanciate your main window

Again I don't know tkinter so you might want to wait for someone who does

[thorny star]

Anyone?

i was following a tutorial

they didnt exactly explain the differencesd clearly so i am confused

[wary gulch]

@regal heroncan u show me how to do thast

[tawdry mulch]

Ah, can you try with the method I did, using enumerate()

[tawdry mulch]

What is your code, that does this

[regal heron]

No sorry I have never used tkinter. To get you started make sure you understand classes and objects

[regal heron]

Same result, enumerate() only change how you get row and column indexes

[frail obsidian]

Hello everyone, I have a quick question. I'm just starting out in python. I managed to write a little function that gets some data from an API that I find interesting. Now I'd like to represent that data in the form of a graph. What would be the easiest way for a beginner to get a graph to show? I've done some HTML and CSS a very long time ago, but no javascript. So not sure if a web page would be a good way to try that.

And the data that I'm working with right now is just list with floats in it. Nothing too difficult.

[graceful viper]

there is matplotlib for desktop apps. The web has multiple javascript libraries

[graceful viper]

I saw people were using unity

[frail obsidian]

Yeah but my javascript knowledge is real bad, I'll check out matplotlib. Thanks!

[graceful viper]

depends on your situation. If you want web - javascript is your choice

[frail obsidian]

Not necessarily, I just want to look at a graph for now. What ever it is generated by 😆

[graceful viper]

ah, then - matplotlib

I am planning to start a gui project, it is simple enough to be created in Tkinter or PyQt5. I want it to be graphical appealing, which module should I use to do that, Tkinter or PyQT5?

[digital rose]

Hey guys, window_1.iconbitmap("sounds/nat.ico") why wont this work?

(Tkinter)

[digital rose]

I can send you some resources but use pyQt5

Had more capabilities then tkinter functionally with all the pre built methods called pyQt5-tools

And it's simplicity of using Qt designer which can be either in a ui file contain xml code

Or you can compile the file and make it in python code.

[plush stream]

Yeah idk abt that. I've been using pyqt/pyside in pycharm for almost 3 years now and it's still have that "unresolved reference" warning for some function/methods.

[cursive basin]

# noinspection PyBroadException add this line above the class you are using

oi

[static cove]

hullo

[digital rose]

thanks for taking the time to help out mate

@static covehttps://www.codespeedy.com/digital-stopwatch-gui-application-in-python-pyqt5/

so the timer works fine for my program right now thankfully

issue is his layout is different then mine I used a loadUi function from pyqt5

which just loads a XML file from Qt designer

I know this will cause issues long term

so I'm wondering how can I load a complied Ui file with pyuic

which I did for one window

but struggling for the other

and other big problem is how will the stop watch timer actually run when it's clicked and switch to the other Window

[static cove]

so what does your code look like now?

[digital rose]

you want me to send it in dms

kinda weird looking rn

😅

[static cove]

!paste you can also use our paste site
With GUIs it's hard to not get it to look weird

[proven basin]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

one thing though if you look at this part #timer function step up

it actually ran the same exact window without using loadUi

which made me think LoadUi wouldn't work with the functionally of thinking of

[static cove]

So, I'm a bit confused here. Why do you have 2 def __init__ for Breakplay?

also, when you make play_break, could you try something for me? Could you make it self.play_break and make it part of the instance?
Also, in that same function, could you add a self.play_break.show()?

[digital rose]

@static covemy bad mate just went to pray

[static cove]

no worries! I'll be around for at least another hour

[digital rose]

ok

thanks a lot bruv

honestly mans been dying on this

[digital rose]

ya about that when I seen that init was already in the other method

I was confused

[static cove]

You can just put the stuff in the second __init__ into the first and have it all together

[digital rose]

because I used a layout from another tutorial it was good but she didn't haven't the functionality I needed.

[digital rose]

where's self.play_break

[static cove]

So that would be inside the def PlayWin(self) function.
We're changing: play_break = Breakpaused() to self.play_break = Breakpasued(), just to make sure it attaches itself to the instance of the class

[digital rose]

my bum ass

sorry

😅 I'm getting lost with the amount of shi I got

[digital rose]

I see

[static cove]

haha, GUI stuff takes a bit to get used to. You're fine~

[digital rose]

ya it's fun ngl though

ya it works

ut it highlight's play_break in the widget.addwidget

my bad it's because I need to use self.

hello

@static cove

[static cove]

hi hi

[digital rose]

ya

it works

[static cove]

So does that create the new window and all that jazz? Whoo!

[digital rose]

I wish

it works normally though which is good

[static cove]

Did you add the self.play_break.show() below that?

[digital rose]

but doesn't switch windows

[digital rose]

ya

like in line below setcurrentindex

[static cove]

So the issue now is that it creates the window, but doesn't switch to it?

[digital rose]

actly

exactly

[static cove]

So, there's a few different ways to do this depending on what you want. Do you want this new window to always be on top as long as it's active? Do you still want to show the original window or do you want to completely hide that when the new one is active?

[digital rose]

bruv

you actually understand this thank you

the first one would effect the function in the beginning

because when I do that it won't use the window which is running before

if that makes sense

like the timer function is running in a different window

but I want to do the last one where I hide the button what was clicked

which is the play button

[static cove]

So just hiding the button?

[digital rose]

like this

and switch the button to a pause button

which is in a different window

and I wanna ask though

with this method where as it changes the button which is just Ui file

that Ui file which switch different buttons to just as it did with the Play

[static cove]

So you want to hide the Play button, open a new window which will have the Pause button?

[digital rose]

yup

it will look like this

[static cove]

How will the play button reappear? When the first window is closed or when the pause button is pressed?

[digital rose]

that's what I wondering

from the tutorial I seen

she used the same exact method

from the other class

which was just flipping through clicked.connect() methods.

bruv are you building my whole program

https://tenor.com/view/sad-baby-cry-tears-cute-gif-17855976

[static cove]

So, in this case, because it's a different window, here's roughly what I would do to start:

def PlayWin(self):
  self.play_break = Breakpaused(self)
  widget.addWidget(self.play_break)
  widget.setCurrentIndex(widget.currentIndex()+1)
  self.play_break.show()
  self.ui.Play.hide() # This hides the button on the first window
  self.play_break.activate() # This makes this widget have the focus

and then, in your Breakpaused class at some point you want something like this as the function that's connected to the Pause button.

For this, we're going to have to change how the Breakpaused class works. Eventually you might have to use pyqt's signal/slot method. But for now, we can actually just reference the parent directly since we don't need the two windows running simultaneously doing 2 different things.

class Breakpaused(QDialog): # Switches to another window when action of PlayWin method is detected.
  def __init__(self, parent_window): #parent_window is window1, it needs a reference to send the signal back
    super(Breakpaused, self).__init__()
    loadUi("Study timer project\Windows\Break windows\Timer_design-BreakPause.ui",self)
    self.pause_button() # Let's pretend this is defining the pause button
    self.pause_button.connect(self.pause_func)
  
  def pause_func():
    self.parent_window.ui.Play.show()
    self.hide() # or you can send an `emit` signal that the parent is connected to and close it from the main window

This is a bit rough, but maybe you get the gist?

[digital rose]

https://tenor.com/view/nervous-nilly-30rock-drink-shaking-nervous-gif-15622273

self.ui.Play.hide() # This hides the button on the first window

does it hide it as in making it blured

and then, in your Breakpaused class at some point you want something like this as the function that's connected to the Pause button.

exactly to do like vice versa

@static coveoi

sorry to bother

from what you guided me through yesterday

what singals and slots would I used from pyqt5 to have such event's happen

[pseudo folio]

Does anyone here know how to create a "snappable grid" background in python. (For example, like the layout grids that CAD programs use, where lines can only be placed on grid points)

[digital rose]

i have a question, the question being: is there any way to use transparent images in (png) format as button images in tkinter cause when i do so although my image is transparent it seems to add a quadrilateral around the area which is transparent...

[brave belfry]

in pyqt I have two events connected to the same method. A mouse double click and a mouse move, however the mouse move event never triggers

does anyone know why this would be the case?

the double click works as would be expected and prints mouse coordinates to console

the move event however does nothing and according to pycharm's debugger is never even triggered (although my mouse certainly is moving)

[brave belfry]

update: if this were instead to say self.mouseMoveEvent = self.getPos then the method is called however the wrong result is given as the position relative to the window and not the image is displayed. I really do not understand this behavior. Would appreciate any help!

[static cove]

@blazing pine So! What would you like to know about my pyqtgraph usage?
My use case is: I'm in Research & Development and I often code programs that "glue" together and control our various instrumentation (a lot of it built by us or very, very niche). My most recent extensive use of it was we had wind sensors across our test grid. Our testing was highly dependent on the direction and speed of the wind. So I needed to read in at minimum 9 different sensors over network, saved the last X values in memory, and used pyqtgraph to plot them real-time. The pyqtgraphs and subsequent calculations were used a go/no-go decision maker.

[blazing pine]

good call on migrating the discussion here

was mostly curious if you're using line plots, scatter plots, 3D capability, and how "big" your data is (and how frequently it updates)

[static cove]

My fave features in pyqtgraph that keep me coming back:

• Native interactivity with literally no effort from me (My sponsors love to be able to zoom in/out and adjust the data on the fly, I look awesome when that functionality is there)
• The real-time reliability of it. I have had literally 0 issues with pyqtgraph being able to process a decent amount of real-time data.
• A nice feature I like is being able to pass epoch times into the plot and it natively turning it into datetime. I've found pyqtgraph's handling on datetimes on axes to be a bit clunky if I don't go this route.

So for real-time, it's a combo between line and scatter. My post processing involves plotting plumes and that is done in 3D.
My data is small but it updates a few times every second. Between all my sensors and instrumentation, I think I pull 10 data points a second.

[blazing pine]

our datetime axis is definitely.... could use some love 😆

[static cove]

I was actually looking to contribute to it the next few months since my work project is diving into it again and I could definitely justify getting paid to contribute back for that functionality

[blazing pine]

we always welcome contributors... last few weeks things have been relatively idle... I needed to take a break from after-hours dev work (found myself getting really sleepy really early in the evenings), i'm looking to do another patch release shortly

one feature on our horizon that may be of interest to you is not having a massive performance hit when updating line plots with lines > 1px wide

[static cove]

ooooh, that I would definitely be interested in

[blazing pine]

while tinkering w/ QtCharts we noticed they were able to have really good performance w/ lines > 1px thickness, I dove into the source (yay OSS!) and saw they use QPainter.drawLines instead of QPainter.drawPath when tinkering around ourselves we noticed the drawLines method handles thick links much better than drawPath

[static cove]

Oh! One feature I was seeing if I could incorporate is figuring out how to do Matplotlib's quiver within pyqtgraph itself. I managed to cobble something together, but that's one feature I'm missing

[blazing pine]

quiver feature? you have a link/image handy?

[static cove]

link: https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.quiver.html
let me see if I can find an image, but it's essenitally an easy way to plot 2-D vector data with magnitude expressed by scale.

[blazing pine]

while we have highly optimizes our numpy array -> QPainterPath code (it was already fast but we've sped this up tremendously the last 6-8 months) so going from QPainter.drawPath to QPainter.drawlines will be a performance hit, we will need to figure out how to handle this a bit more when to use what method...

but drawing thick lines and not having the performance plummet is probably our biggest feature request right now...can't believe we stumbled into a workaround on accident the way we did

[static cove]

Very similar to stream plot but not quite

[blazing pine]

ahh, a stream plot is something I've been thinking about (my background before CS was mechanical engineering, so I have an interest in fluid flow which can be nicely displayed w/ stream plots) but I've never been sure how well they would fit within pyqtgraph so I haven't really pursued it much.

[static cove]

I'm also primarily a fluid flow person! The work I do where I get paid has me dealing a lot with wind vectors. I had the specific request of doing a quiver, but only the data points that we have. No stream plot for interpolation. The sponsors very were touchy about interpolating wind data since our test set-up was a bit wonky

[blazing pine]

now that I'm doing a google image search for quiver plots I see what you're getting at

[static cove]

Also, I have to go. Looks like the Tornado Watch is now a Tornado Warning and I should probably get home before the worst of it hits...

But I'm happy to talk more about this in like an hour

[blazing pine]

i have a meeting in an hour, will be happy to talk about it more then too 😆

[glossy temple]

hello i was wondering if anyone can recommend a gui framework for a chess game? Ive looked into different comparisons of the main ones but they all just describe the project never mention any features. I need basic features like text, buttons and entry boxes but also more advanced like dragging and clicking as well as moving things, and the ability to insert shapes for the board, as well as other features a chess app would use.

[blazing pine]

Qt can definitely do that; depending on how much control you want over the board that's being drawn, you can do it as a simplified QGridLayout, or if you wanted more control over how the board is drawn, you can use a QGraphicsView bit

[static cove]

@blazing pine But having a real-time quiver in pyqtgraph would be pretty stellar for me

[blazing pine]

for the record, I have nothing against that feature, and I certainly wouldn't discourage a PR to add it (and I'm fairly sure none of the other maintainers would have an issue with adding it).

@static cove what would mouse-interaction on the plot look like (ideally from your perspective)?

I guess zoom in/out makes the most sense...

[static cove]

Being able to hover on a line, get the x/y and any other details attached to it. Panning, zooming.
I know this is totally out there, but it would be super neat if there was like... an annotation mode?

[blazing pine]

"annotation mode" ...you're not the first person to bring this up...

and I think it's a great idea ....

[glossy temple]

Hey thanks ill start looking into pyqt now

[blazing pine]

i'm still not sure what that would look like (someone referenced the annotation mode in the matlab plot windows)

[blazing pine]

@static cove if you know of companies that are looking for software folks to work w/ flow data let me know; I'm starting to look for other work, would love to be able to put my mechE education to work

[static cove]

Will do!

[digital rose]

@static covehey mate you free

[real wyvern]

does anyone know a UI framework that supports reinitialization from the same python shell without thread restrictions? ex: without reopening python at all, run a ui script, fully close all the windows, run it again and it works?

[static cove]

hey, what's up?

[digital rose]

sorry to bother

I'm trying to figure out how to implement signals and slots to the program

[static cove]

just to practice signals and slots or to do something specific?

[digital rose]

to do that specific thing you were explain with the code last time.

[digital rose]

@static covehere

[static cove]

So for this you don't even really need signals/slots yet. You just need the second window to have a reference to the first. Which I think my code walks you through

[digital rose]

what do you mean by second window which has reference to the first

I have a second one which contains the pause button

[static cove]

Let me see if I can create a quick example

[digital rose]

Appreciate it

[static cove]

from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton, QLabel, QWidget, QHBoxLayout, QVBoxLayout

class FirstWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.label_a = QLabel("First Window")
        self.label_b = QLabel("Current Status: Stopped")
        self.second_window_btn = QPushButton("Open Second Window & Start", clicked=self.show_second_window)
        
        self.layout = QVBoxLayout()
        self.layout.addWidget(self.label_a)
        self.layout.addWidget(self.label_b)
        self.layout.addWidget(self.second_window_btn)
        self.setLayout(self.layout)
    
    def show_second_window(self):
        self.second_window = SecondWindow(self)
        self.second_window.show()

class SecondWindow(QWidget):
    def __init__(self, parent):
        super().__init__()
        self.parent = parent
        self.start_btn = QPushButton("Start", clicked=self.start_parent)
        self.stop_btn = QPushButton("Stop", clicked=self.stop_parent)

        self.layout = QHBoxLayout()
        self.layout.addWidget(self.start_btn)
        self.layout.addWidget(self.stop_btn)
        self.setLayout(self.layout)

    def start_parent(self):
        self.parent.label_b.setText("Current Status: Started")

    def stop_parent(self):
        self.parent.label_b.setText("Current Status: Stopped")

app = QApplication([])
w = FirstWindow()
w.show()
app.exec()

Take a look at this code and you'll see how from the second window, I can control text on the first. This is done with a simple reference to the first window. So the second window can control things on the first with that reference, which is self.parent = parent in the __init__. Let me know if you have questions

[digital rose]

Thanks mate

and would button attributes of each class allow me to have an effect on let's say a LCD timer output

to pause it or play it

[pseudo folio]

How do I control the minimum distance someone can move an item in the MouseMoveEvent in PyQt? ( For example, I want the user to only be able to move an item in units of say 10 pictures.)

[fossil bronze]

i'd like to plot continuous wavelets (i'd use pyplot.matshow(coef, fignum=1, aspect="auto") in jupyter) but in pyqtgraph instead, anyone know how to do that?

[steel wagon]

If anyone is familiar with tkinter would you spare the time to see if you could help with my question in #☕help-coffee would be incredibly helpful 🙂

[fossil bronze]

distance in what sense?

cm for the user? pixels? some imaginary unit?

[pseudo folio]

Like how in a CAD program there is a grid and items 'Snap" to it.

So they cannot be placed in between grid lines.

[fossil bronze]

that doesn't really answer the question

[pseudo folio]

Either CM or pixels would be fine.

[fossil bronze]

you know those two can differ widely and strongly depend on your physical device you're working with, right?

[pseudo folio]

I can use pixels.

I want to give predefined points or grids for items to "snap" to. The distance is likely not going to change.

[fossil bronze]

you could just take the position of the mouse and // gridsize

or round()

[pseudo folio]

Can you point me to an example of what you mean? I am pretty new to pyqt.

[fossil bronze]

hmm.. https://stackoverflow.com/questions/41688668/how-to-return-mouse-coordinates-in-realtime maybe?

maybe rather check the position of the mouse on mouse release event

[pseudo folio]

ARe you proposing dividing the mouse position by the grid size to figure the closest "grid point", then set the item position to that?

[fossil bronze]

then you can "snap" to the grid from there

[fossil bronze]

exactly

[pseudo folio]

If I checked it during mouse move, then I could do something similar?

[fossil bronze]

yeah, but you probably only need it on release

[pseudo folio]

If the mouse is dragging an item, I could check the item position instead, correct?

[fossil bronze]

yep

[pseudo folio]

OK great.

Thanks.

[fossil bronze]

wait

item position?

[pseudo folio]

For example, in this program users drag pre-defined objects onto the scene, and then are able to move them around.

[fossil bronze]

you don't work with item position while dragging, the item moves relative to the mouse

[pseudo folio]

Oh ok.

[fossil bronze]

so if your item has width and height, you can add/subtract that from your mouse position

[pseudo folio]

Got it.

[fossil bronze]

position and distance are very weird concepts in computers 🙂

you always need to keep in mind what is your point/frame of reference

and the position of an item depends how you define it (some take the center, some take a corner)

[pseudo folio]

Got it.

[fossil bronze]

translating from pixels to cm is another can of worms

[pseudo folio]

Or might have two ends if it is a line.

[fossil bronze]

you need the physical resolution of the screen for that

[pseudo folio]

I do not need to translate to cm.

In this case.

[fossil bronze]

ok

units in blender, CAD etc are basically arbitrary

[pseudo folio]

Gotcha.

[fossil bronze]

now, how to visualize continuous wavelets in pyqtgraph? anyone? 🙂

[steel wagon]

If anyone is familiar with tkinter would you spare the time to see if you could help with my question in help-coffee would be incredibly helpful 🙂

[digital rose]

@fossil bronzeoi

[blazing pine]

there is a "scrolling plots" example in the pyqtgraph library that you can take a look at; granted one of the examples right now is currently broken (there's an open issue already) but it should give you a place to start

here's the code: https://github.com/pyqtgraph/pyqtgraph/blob/master/examples/scrollingPlots.py

if you have pyqtgraph installed already you can run this code by running

python -m pyqtgraph.examples and selecting the "Scrolling Plots" and hit the run button.

[blazing pine]

actually on re-reading, could you provide a screenshot/image of the kind of plot you want ... oh matshow displays images, so disregard the scrolling plots example I referenced, look at the "Matrix Display" example here: https://github.com/pyqtgraph/pyqtgraph/blob/master/examples/MatrixDisplayExample.py

the code there generates the following plot

[fossil bronze]

@blazing pine thanks so much for replying, i already thought of poking you directly 🙂

i can give you an example of what i'm dealing with, hold on

this is how it looks for me

coef, freqs = pywt.cwt(data, range(1, 50), pywt.ContinuousWavelet("gaus1"))
pyplot.matshow(coef, fignum=1, aspect="auto")
pyplot.colorbar()
``` that's the code

https://pywavelets.readthedocs.io/en/latest/ref/cwt.html#single-level-cwt that's the cwt

[brave belfry]

If anybody knows, upon some further digging, it would appear that pyqt's QGrapicsView does not allow the mouseMoveEvent without a previous mouseClickEvent being issued. Does anybody happen to know a workaround for this?

[cursive basin]

If mouse tracking is switched off, mouse move events only occur if a mouse button is pressed while the mouse is being moved. If mouse tracking is switched on, mouse move events occur even if no mouse button is pressed.

QGraphicsView().setMouseTracking(True)

class MyQGraphicsView(QGraphicsView):
    def __init__(self):
        super().__init__()
        self.setMouseTracking(True)
    def mouseMoveEvent(self, event):
        print(event.windowPos().x(), event.windowPos().y())

Hello could some one help me who knows tkinter i want to make 4 cubes at each side of a window so a cube at a left side right side and left down cube and right down cube

I want to make it like this but idc how

[tranquil jasper]

thinking of havnig GUI for a python program , i looked for tkinter. But before diving into it, i was wondering if giving time to learning tkinter would be worth it, considering its use in the industry?

[tawdry mulch]

Would you start learning thermodynamics before you learn the basic physics and chemistry🤔

[tawdry mulch]

What is your code so far

[tranquil jasper]

nope

[tawdry mulch]

So yea, tkinter has alot of fundamentals that can get you started with GUI and event loops

[blazing pine]

I jumped into Qt as my first GUI framework, never wrote a line for tkinter, I'm sure it's used someplace ... it has some benefits with respect to Qt, probably would look at what the respective trade offs are

but generally speaking, I don't think there are that many commercial tkinter applications out there...

[tranquil jasper]

thats the reason i have this question

[tawdry mulch]

I myself, have never went through a tutorial for PyQt but yet I am able to make GUI with PyQt, all I know is tkinter and it made me understand how event loops and event driven programming works. I can create most types of GUI in PyQt now given that I know all the elements to be used.

PyQt is OOP based, if you do not know that, tkinter is a very good place to start with procedural code and then slowly move into OOP

[blazing pine]

I mean, any time you learn multiple frameworks you're going to get better at both... for example, my Qt skills improved when I learned Swift + UiKit

tl;dr there is no good/bad answer here, do what you want 🙂

[tranquil jasper]

so thats there too

[tawdry mulch]

Do you know OOP?

[tranquil jasper]

yep a bit

[blazing pine]

ha, Qt was actually my first dive into OOP, it worked well as each GUI widget was its own object/methods and really detailed how inheritance worked

[tranquil jasper]

but i mean would it be worth the time learning tkinter and not electron js?

[tawdry mulch]

Hmmm maybe you can start with PyQt, and then if you feel difficult move down

[tranquil jasper]

im confused what to choose b/w these. Sceptical about tkinter's use in the industry

[tawdry mulch]

Personally I would say you start with tkinter because you learn diff ways to do stuff, and then in PyQt it is all inbuilt, and much easier. So you are progressing forward, anyhow

[blazing pine]

there is no consensus in industry

[tawdry mulch]

tkinter is not used in industry.

It is just a learners tool nowadays

[blazing pine]

each framework has its own downsides and benefits

[tawdry mulch]

Yea it is quite deep

It is used it pythons IDLE and also I think Komodo IDE

[tranquil jasper]

im a bit inclined towards electron js just because i 'see' it in use 👀

[tawdry mulch]

If you want to make webapps, then yea sure learn js

Python is not meant for GUI, yet there are many great frameworks out there

I am 99 percent sure, that you would not be wasting time learning tkinter as it is much bigger than you think and will help you as a great start on GUI

Yes I am 100 percent sure, but 99 is just so that you don't end up suing me later 😛 and also cuz different people are built different

[tranquil jasper]

haha ty for that.
lets begin with tkinter then

ty for your time coolCloud and j9ac9k

[stable mountain]

Hello i want to make this but ad far i did only the top blue and down green

Here is my code ```py

canvas.pack()
 
#pravljenje plavog kvadrata
kvadrat1=canvas.create_rectangle(0, 0, 100, 100, fill='blue', outline='blue')
#pravljenje crvenog kvadrata
kvadrat2=canvas.create_rectangle(300, 300,400,400, fill='red', outline='red')
 
 
#funkcija koja pokrece kvadrate na ekranu
def redraw():
    kordinate_kvadrata1 = canvas.coords(kvadrat1)
    kordinate_kvadrata2 = canvas.coords(kvadrat2)
    if (kordinate_kvadrata1[1] >= height or kordinate_kvadrata2[0]>=width):
            root.after(1, root.destroy)
           
    canvas.after(50,redraw)
  
    canvas.move(kvadrat1,5,5)
    canvas.move(kvadrat2, -5,-5)
 
redraw()
root.mainloop()

If some one can help me make the yellow and red cube i rly dont know how

[tawdry mulch]

it is much easier if you visualize stuff

Hello, I'm looking for some way to integrate two windows into a frame widget.

So, I have the first Script that generates these 2 widows, but I want to import them into my tkinter GUI and insert them into a frame when a Button is pressed. How could do this?

[tawdry mulch]

Window inside a frame..?

[twin crater]

not a tkinter window()

[proven basin]

:incoming_envelope: :ok_hand: applied mute to @frank whale until <t:1630605907:f> (9 minutes and 59 seconds) (reason: duplicates rule: sent 4 duplicated messages in 10s).

[twin crater]

Do you have any approach to do this?

[tawdry mulch]

No I do not think so

[fossil bronze]

you're wrong, many installers use tkinter

simply because it comes with python

[tawdry mulch]

Suddenly, that is industry?

[brave belfry]

Thank you so much for this!

the next issue I am having is enabling the user to draw resizable rectangles between the point where the mouse was clicked to where the mouse was released. As far as I understand QPainter cannot be used with QGraphicsView and simply using the addRect method upon mouse move seems to crash my program probably due to too many rectangles being drawn. Anybody got any suggestions for this?

[cursive basin]

maybe use https://doc.qt.io/qtforpython/PySide6/QtWidgets/QStylePainter.html#qstylepainter

use the mouseMoveEvent there and there only

[fossil bronze]

industry can be many things

[tawdry mulch]

ok installers, great

[brave belfry]

Hmm, thank you, I am not at home at the moment but I will look into this when I get back!

[blazing pine]

tkinter applications are likely used in industries where installing dependencies are tricky; and there is value in having something only need the python interpreter

[cursive basin]

is there a way to customize this pop up for hiding the docker in QMainWindow without like create it from whole through createPopupMenu

[eager beacon]

That looks like a QToolBar popup, is that right?

[cursive basin]

umm no like this pop is for like hiding toolBars, dockwidgets and stuff it comes with QMainWIndow

currently it doesn't show a text for what is it hiding

[eager beacon]

What is it actually hiding?

[cursive basin]

a dock widget

[eager beacon]

oh

as far as I know you'll have to use createPopupMenu
and set an action with whatever text you want it to display

You might be able to get away with setting a QMenu and a contextMenuPolicy but I'm not that familiar with Dockwidgets

[cursive basin]

    def createPopupMenu(self) -> QtWidgets.QMenu:

        menu = QtWidgets.QMenu()
        dock_action = QtGui.QAction("Hide Docker", self)
        dock_action.setCheckable(True)

        def dock_action_func():
            if dock_action.isChecked():
                self.initialise_right_docker()
            else:
                self.removeDockWidget(self.right_docker)
        dock_action.triggered.connect(dock_action_func)
        menu.addAction(dock_action)
        return menu

alright i did this but it doesnt pops when right clicked on the menu bar

eh leave it fixed

[eager beacon]

what was the problem?

[twin crater]

Does anybody know how I could get the index of a Combobox option selected?

i mean, if the values of the combobox is a List, how could I get the index of the selected option?

i've tried this but it does not work: py camBox=ttk.Combobox(fAct, values=user_list, width=20) camBox.place(x=140,y=50) user_selection=camBox.get() user_index=user_list.index(user_selection)

[tawdry mulch]

Yea this should work, but you should put the getting and searching inside a function

[blazing pine]

so, I'm migrating my project from PySide2 to PyQt5 for #reasons; but I'm stuck on one behavior I'm not sure how to work around.

I had something like ...

myQThreadSubClassInstance.disconnect(myQObjectSubclassInstance)

basically, I was trying to disconnect all signals from a specific QThread instance that were connected to another QObject subclassed object...

this was fine in PySide2 but PyQt5 raises errors ...

TypeError: arguments did not match any overloaded call:
  disconnect(QMetaObject.Connection): argument 1 has unexpected type 'Spectrogram'
  disconnect(self): too many arguments

I've tried a bunch of variants (disconnect() with no args for example) but I'm not able to get it quite working; any suggestions?

with no args:

    self.spectrogramController.currentThread.disconnect()
TypeError: disconnect() of all signals failed

also tried with passing the signal name in string form QThreadSubclass.disconnect("signalNameAsStr", self.slot)

    self.spectrogramController.currentThread.disconnect("sigSpectrogramComputed", self)
TypeError: arguments did not match any overloaded call:
  disconnect(QMetaObject.Connection): argument 1 has unexpected type 'str'
  disconnect(self): too many arguments

at this point, I'm considering wrapping the disconnect call w/o any args in a with suppress(TypeError): and see if that works better

[eager beacon]

I went through this a few months back but ended up reverting the code so I don't have it anymore. It was a huge pain to figure out how to get it working correctly. I remember I had to use QMetaObject.Connection in the call to disconnect

[blazing pine]

huh, never used that object before...

[eager beacon]

Neither had I and from what I remember the documentation wasn't super helpful

I ended up looking for examples on github to see how it was being used before I got it working correctly

[blazing pine]

that's what I'm doing just now, and remarkably, I'm seeing zero examples in python

@eager beacon thanks for sharing; I felt like this was a bit of a too specific ask for this community, clearly I was mistaken 😆

[eager beacon]

Sorry I couldn't be more helpful.. I even grepped through my git history but apparently i never even added the changes 😦

[blazing pine]

it's fine, seeing some stack overflow examples I think I can sort this out...

[eager beacon]

I hope you find something thats easier to implement that what I had. There must be a better way to go about it, but all of the simple ways that i found where people mentioned it had worked for them no longer worked for me.

[blazing pine]

i got it!

wasn't too bad at at all...

[eager beacon]

What did you end up with?

[blazing pine]

two different files...

        metaSpectrogramComputed = spectrogramCalcThread.sigSpectrogramComputed.connect(
            self.plotView.spectrogram.newSpectrogramImage
        )
        metaSpectrogramCalcThread = spectrogramCalcThread.sigFrameComputed.connect(
            self.plotView.logEnergyPlot.updateEnergyPlot
        )

        self.metaObjects = (metaSpectrogramComputed, metaSpectrogramCalcThread)

other file:

        if self.spectrogramController.currentThread is not None and hasattr(self.spectrogramController, "metaObjects"):
            for metaObject in self.spectrogramController.metaObjects:
                self.spectrogramController.currentThread.disconnect(metaObject)

sorry for the long namespace here 😛

it's the Qt way 😆

[fluid mica]

#help-chestnut

#help-cherries

[eager beacon]

Yeah that looks familiar

You found an example on Stackoverflow?

[blazing pine]

tl;dr I saved the output of the "connect" calls; and used those references in the disconnect...

not an example, but a comment, let me dig it up...

[eager beacon]

Oh nice, I must have glossed over it

[blazing pine]

You can save QMetaObject::Connection objects returned by QObject::connect and use them in QObject::disconnect. It's not so much extra work. –

from here: https://stackoverflow.com/questions/21384900/disconnecting-slots-from-signals

[eager beacon]

ouch, I think I probably saw that and ignored it because it was posted back in 2014 and assumed it only applied to pyqt4.

[blazing pine]

ha yeah ....that gets me all the time, now if only qtpy and fbs would get on with supporting Qt6 😈

[eager beacon]

yeah, fbs is in serious need of an update

[blazing pine]

i paid for "fbs pro" which works w/ latest qt5 + latest pyinstaller

it's for a work project, the money for that license easily made it worthwhile

[eager beacon]

Oh cool, I didn't even know that was an option.

[blazing pine]

yeah, for work stuff it's a bit of a no brainer

[eager beacon]

Oh cool, I didn't even know that was an option.

You use PyQt professionally?

[blazing pine]

I maintain an internal PyQt application at my (small) company

my user-base is in the couple of dozen range... not huge, but they are on all platforms, and distributing the source was a pain point I've been avoiding

[eager beacon]

Oh, thats cool, I don't come across many people who actually work with PyQt

[blazing pine]

unfortunately the last few months I've been pushed to other projects, went to tackle a bug, and ran into a variety of build issues...

I'm also a maintainer of pyqtgraph

so I work w/ Qt a fair amount (wouldn't say I know it all that well though 😆 )

[eager beacon]

and yeah, with a couple of dozen users and distributing the source code... you'd probably not have much time to work on the app with all the tech support you'd be doing

[blazing pine]

my users are somewhat tech literate, they are expected to remote ssh into users and run basic bash commands....

but yeah, I really don't want to be talking people through setting up virtual environments a million times over

especially if I can give them a .exe, .app or .deb bundle

[green stump]

Is it possible for certain elements inside a QT layout to occupy more space than other elements and how do i do that?

in PyQt is there a way of enabling QGraphicsView dragging and mouse move event at the same time

I would like to enable mouse coordinate tracking at the same time as being able to pan the image etc (ignore the placeholder image lol)

Please someone explain to me what this error says:
TypeError: descriptor 'fbind' for 'kivy._event.EventDispatcher' objects doesn't apply to a 'str' object

Are you using a QGraphicsPixmapItem to get the coords?

[brave belfry]

yes

[eager beacon]

Then that means that the X/Y values do not change since when you pan the image, the mouse grabs the PixmapItem and moves it around the view

The X/Y values are not that of the graphics view but the current position of the mouse cursor over the pixmap

Does anyone know how I can change the value of a variable "x=cv2.VideoCapture(0)" belonging to a script, lets call it A, and from a script B, pick the argument of variable x, (which is 0), and change it to another one?

Is it possible for certain elements inside a QT layout to occupy more space than other elements and how do i do that?

[eager beacon]

You can use a grid layout and set the column/row stretch or you can set a minimum height or width on whichever widget you want to change.

you can also set a minimum row/column size with a grid layout for each col/row in the layout

you can do all of that in Qt Creator/Designer

[green stump]

awesome thank you

Btw, I haven't been able to find Qt Creator

Is it paid?

[eager beacon]

No, its not paid but it usually comes bundled with the C++ installer although you can find it as a standalone by googling for 'QtCreator offline installer'

heres a simple example of the row/column stretch in creator

[green stump]

Okay thanks! do you recommend it for pyqt dev?

[eager beacon]

yes, PyQt or Pyside are the best options

[green stump]

I mean do you recommend Qt Creator for pyqt?

[eager beacon]

Oh, i misread that.. Yes, it can speed up your design a ton

[green stump]

gotchu!

[eager beacon]

Designer is pretty much the same thing without the code editor though so you could stick with that.

I'm not sure how good the editor that comes in creator is for python code
