: You are right that there is a naming conflict.  Unfortunately the

: it tag_raise() as you propose.

Actually, I got the name "tag_raise" from the method in the Text class
of the same name.

: Unfortunately, I cannot make this change without breaking all existing 
: code that was using Canvas.tkraise() for raising Canvas items (instead 
: of raising the Canvas itself).  I can add tag_raise() and then in 1.6
: we can delete the tkraise() and lift() names.

Good enough for me.

: Other issues:

: - As someone else suggested, the proper solution is
: Misc.tkraise(canvasobject).

The proper interim solution only, I think.

: - /Fredrik Lundh is responsible for *documenting* Tkinter, but not for
: its maintenance (although he contributed a bunch of support modules).
: The maintenance of Tkinter is strictly my responsibility.  (Not that I
: asked for it. :-)

Well.. I knew he was in there somewhere. ;)  Sorry, Fredrik!

: - 1.5.2 will more likely be released around mid-April.

I'm awaitin'. :)

Thanks, Guido!
