Increase Numbers forever and need reset? - ATARI_LIVE - Oct-23-2020
Here my code for the mouse click modes 0 = released, 1 = clicked, 2 = press and hold.
It's WORKS.
from tkinter import *
lp_id = pressmode = 0
window_1 = Tk()
window_1.attributes('-fullscreen', True)
window_1.configure(bg='black')
def mouse_pressed_id(event=None):
global lp_id, pressmode
if event is None:
pressmode = 2
elif event.type == EventType.ButtonPress:
lp_id = window_1.after(3000, mouse_pressed_id)
pressmode = 1
elif lp_id:
window_1.after_cancel(lp_id)
lp_id = None
pressmode = 0
print(pressmode, lp_id)
window_1.bind("<Button-1>", mouse_pressed_id)
window_1.bind("<ButtonRelease-1>", mouse_pressed_id)
window_1.mainloop()Output:started

Why do you care about the value of some event handle? If I was writing something like "after" I would make sure to create a unique handle for each event. In the code below I create and delete a Frame each time the mouse button is pressed/released. Each time I get a different ID for the frame. Would you want to reset the frame ID?s
from tkinter import *
mouse_repeat = None
window = None
root = Tk()
def mouse_event(event):
global window
if event.type == EventType.ButtonPress:
window = Frame(root)
print('start', window)
elif window is not None:
print('cancel', window)
del window
window = None
root.bind("<Button-1>", mouse_event)
root.bind("<ButtonRelease-1>", mouse_event)
root.mainloop()

Thought it might eat up to fill the memory? and slower?
RE: Increase Numbers forever and need reset? - deanhystad - Oct-23-2020
You can test if it "eats up memory" or is slower. I doubt either, but if you are concerned about that you should test and verify. Then if you have a legitimate concern you can try to figure out how to reuse the after handles. Until then your time is better spent writing code.

I see the task performance seem not effects... I guess I have to ignore it. thanks.
