Video player by Python tkinter, When I pause video, I cannot re-play
Question: Pause button will have no effect.
Reference:
Tkinter.Widget.after-method -
after(delay_ms, callback=None, *args)Registers an callback that is called after a given time.
Tkinter.Widget.after_cancel-method -
after_cancel(id)Cancels an callback.
To cancel the allready queued events for self.play_video change the following:
def play_video(self): ... if self.pause: self.window.after_cancel(self.after_id) else: self.after_id = self.window.after(self.delay, self.play_video)
I would create another method for the play button callback. Something like this:
def play_start(self): self.pause = False self.play_video()However, I would make sure you disable the play button if it's already playing. Otherwise, you could have multiple "instances" of play_video going if the play button is pressed multiple times.
An alternative is to combine your play and pause button, so it toggles the value of self.pause. Then you could have just one button with one callback function.
