Getting the python right is easy, learning Tk through the mostly  
undocumented tkinter library is worrying me :-)

You're suggestion doesn't help here though, I somehow need to define  
a new TCL proc from python.

With some code browsing I've found how do do this:

<quote>
def doOpenFile(*args):
	print *args

someTkObject.createcommand("::tk::mac::OpenDocument", doOpenFile)
</quote>

I could have known that it would be something simple :-)

This is indeed the kind of changes I had in mind. But those changes  
sound like a lot more work that I'm willing to do. If I am going to  
spend significant time on fixing IDLE I might as well write my own  
IDE :-)

There would also need to be discussion on idle-dev and/or python-dev  
on the Tile-related changes (and other large changes), I wouldn't  
know if those would fly. My guess is that nobody will object if this  
results in a better L&F on Windows and Linux as well.
