[Tkinter-discuss] tk, scrollwheels, and osx

[Calvin Spealman]

I've noticed this even outside of Python, but I have seen tk have  
problems dealing with mouse wheels (ie, doesn't see them at all) on  
OS X and even bad scrolling behavior like locking or jerky movement,  
especially for downward movement. Is there some known issue here,  
like the lack of handling certain events?

There is a bug report about this from someone having issues scrolling  
IDLE. http://bugs.python.org/issue1574
