Re: mouse cursor on MS-Windows. (revisited)

[David PONCE]

Hi All,

I submit you the attached patch to NT Emacs (HEAD) to display
different cursors, depending on mouse position.

This is a revisited patch from the original version posted by
"KOBAYASHI Yasuhiro" <address@hidden>.  See message:
<http://mail.gnu.org/pipermail/emacs-devel/2002-September/012390.html>

The main differences are:

- Cursors are loaded only at frame creation in Fx_create_frame instead
  of each time the cursor change.  The Cursor type is actually a
  cursor handle instead of a resource identifier.  I think it is more
  consistent.

- Cursors are loaded via the new function `w32_load_cursor' that try
  first to load from application resources (defined in emacs.rc), then
  from global shared predefined one.  Thus it is possible to use
  cursors specifically built for Emacs ;-) More important that allows
  to provide a "hand" cursor for Windows 95 and NT for which a
  predefined one does not exists.  I added a sample hand.cur file in
  the nt/icons directory (maybe using a nt/cursor directory would be
  better?).  Notice that I got this hand.cur from winhelp.exe.
  Probably, for license reason, a specific version will be needed?

The patch includes some minor fixes too.  You will find a change log
at end.

Hope it helps.

Sincerely,
David
