How To Change Bg Color Of Button After Pressing And Get Back To Previous Color

In the below program i want to change the background color of the button to green after pressing it and changed color should remain for 2seconds and later change back to original c

Solution 1:

You can use the after method to schedule a function to run after a pre-defined amount of time. You can use the configure method to change a widget option. Put those two together and you have something like this:

def trial(self):
    self.buttonA.configure(background="green")
    self.after(2000, lambda: self.buttonA.configure(background="black")

Solution 2:

it works fine if i put code like:

def trial(self):
    self.buttonA.configure(background="green")
    self.after(10, lambda: self.buttonA.configure(background="black")
    self.after(2000, lambda: self.buttonA.configure(background="green")

But am not sure whether its correct way or not
