simple animation using tkinter
The basic pattern for doing animation or periodic tasks with Tkinter is to write a function that draws a single frame or performs a single task. Then, use something like this to call it at regular intervals:
def animate(self): self.draw_one_frame() self.after(100, self.animate)Once you call this function once, it will continue to draw frames at a rate of ten per second -- once every 100 milliseconds. You can modify the code to check for a flag if you want to be able to stop the animation once it has started. For example:
def animate(self): if not self.should_stop: self.draw_one_frame() self.after(100, self.animate)You would then have a button that, when clicked, sets self.should_stop to False
I just wanted to add Bryan's answer. I don't have enough rep to comment.
Another idea would be to use self.after_cancel() to stop the animation.
So...
def animate(self): self.draw_one_frame() self.stop_id = self.after(100, self.animate)def cancel(self): self.after_cancel(self.stop_id)
