simple animation using tkinter

by

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
