Description:

I want to make a button not clickable until a certain event has occurred. How do I "grey out" the button so you cannot click it, and then re-enable it?

Assuming you are using Tk, not Win32::GUI, you would do it like this:

$button->configure( -state => 'disabled' );

Following up on the previous answer: To enable the button again, you simply do this:

$button->configure( -state => 'normal' );
Note: In my experience with Tk on Win32 and UNIX platforms, I've found that Win32 uses 'disable' while UNIX uses 'disabled'.
