Thanks everybody for all the help.
- unix, MacOS X and Windows each have a different required file format
(the standard format for cursors on that platform). This makes
cross-platform cursors in Tkinter a lot of work -- more than I'm ready
to do right now.
- Unix requirements:
- specify an xbm format file path plus at least a foreground color
(a fancier form allows a mask and background color as well);
- the xbm file must include hotspot info
- the multiple args must be in a tuple
It is conceivable that if one wrote a C interface to
Tk_GetCursorFromData, then one form of data might be acceptable to all
platforms. I'm not ready to try that yet.
