Hi,
Your code doesn't work because you're directly binding to a mouse
click event. The proper (high-level) way of configuring which command
is called when the button is pressed is simply to configure the button with
the command parameter:
button.configure(command=some_function)
Your application modified looks like this, and works as expected. Note
that a function configured for command doesn't have any parameters.
Kind regards,
Ronnie

hi ,i created 3 buttons such that if button1 is clicked it will
disable button2 ,and clicking button3 will restore state of button2 to
normal,
to my dismay i find that button2 still responds to clicks even if it
is greyed out
here is the code..am i doing something wrong? is there a way to truly
disable the button?

def __init__(self,parent):
self.mainframe=Frame(parent)
