How to make a button flashing?

[huey.y.jiang at gmail.com]

Hi All,

I forgot the syntax of making a button flash, and failed to find an example in the web. I use Tkinter, to create a button. Then made it packed, and showed up. Now I am trying to make button b flashing, to make it get better noticed. I checked the docs, and found a method flash() is available, then I tried:

b.flash()

there was no error message popped out, but there was nothing happened also. I wonder who can give me this help? Thanks!
