Tkinter gui doesn't work Mouse and keyboard modules

Question

I was trying to make an auto clicker using Mouse and keyboard modules and tkinter as the gui and wrote this code

#Import
import tkinter as tk
import random as r8
import keyboard as kb
import mouse as ms

class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.pack()
        self.create_widgets()
        self.joesd()

    def create_widgets(self):
        self.joe = tk.Frame(self)#main frame
        self.joe.pack(fill=tk.BOTH)
        self.lbl = tk.Label(self.joe, text='Example text', height=5, width=30)
        self.lbl.pack(side="top")# where the label will be located
        self.lb = tk.Label(self.joe, text='Example Text', height=5, width=35)
        self.lb.pack(side="top")# where the label will be located
    def joesd(self):
        while True:
            if kb.is_pressed('q') == True:
                ms.press('left')
                ms.release('left')

root = tk.Tk() 
app = Application(master=root)
app.mainloop()

Then I noticed that the gui never appears but will appear if I removed

    def joesd(self):
        while True:
            if kb.is_pressed('q') == True:
                ms.press('left')
                ms.release('left')

What should I do?

You shouldn't use the `keyboard`/`mouse` module when using `tkinter`. Instead look at `tkinter` event bindings. — TheLizzard, May 30 '21 at 15:42
@TheLizzard can tkinter event bindings automate key pressing? — AmirTheDev, May 30 '21 at 15:51
@AmirTheDev I suggest that you look at a tkinter tutorial. To use tkinter's event bindings you pass in a function that tkinter calls when somethings happens like a mouse press/keyboard button is pressed. — TheLizzard, May 30 '21 at 15:54
@TheLizzard I am asking whether tkinter can simulate key press. — AmirTheDev, May 30 '21 at 15:55
You could try to alter `after()` to emulate a while loop, don't know if it'll work. — Delrius Euphoria, May 30 '21 at 16:22

The reason why GUI does not show up is that before the code hits mainloop() it goes into a infinite loop(while loop) and it cannot reach mainloop and hence window does not show up and events are not processed. So what you should do is get rid of while. One way is to use after() method to emulate while.

def joesd(self):
    if kb.is_pressed('q'):
        ms.press('left')
        ms.release('left')
        
    self.after(100,self.joesd)

This will repeat the function every 100 ms, you can reduce it to 1ms too. But make sure it is not too much for the system to handle.

You should not use while loop in a tkinter application. You can register a callback using kb.on_press_key() instead:

class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        ...
        #self.joesd() # <- not necessary
        kb.on_press_key("q", self.on_key_press)

    ...

    def on_key_press(self, event):
        #print("q pressed", event)
        ms.press('left')
        ms.release('left')
        # above two lines can be replaced by ms.click('left')

Although this does work it's not what I need, I need the button to continuously be clicked d @CoolCloud did give me another successful answer, but thank you for taking time to review my code. – AmirTheDev May 31 '21 at 08:09
@AmirTheDev If you keep the "q" key pressed, the callback will be kept executing. – acw1668 May 31 '21 at 08:14
That could work but it still not what I need, I want to make an auto-clicker that doesn't require a person pressing something. – AmirTheDev May 31 '21 at 08:16
@AmirTheDev Then I wonder why your code keeps checking `kb.is_pressed("q")`? – acw1668 May 31 '21 at 08:19
