There are two issues here, one getting bitmaps for icons to work on Unix, one on Windows.  

Tk supports setting the icon bitmaps on Unix.  So the only question is where are the bitmaps to use.  At some time in the past, there even were Icons for all the windows on Unix, and they worked - at least on WindowMaker.  Martin did that a while ago, and I don't remember where the icons where, etc...  But I do know that this used to work...

On Windows, you can't use the "wm iconbitmap/iconbitmask" - it currently doesn't do anything.  So if you also want to set the icons for iconified windows (in the Windows start bar) you will have to use an extension, and the only one I know of that does this is winico.

Hope this helps,
