Patch name: patch.beos-gui-fabo
Author: Marton Fabo <morton@eik.bme.hu>
Date: Thu, 6 Dec 2001 19:52:18 +0100 (CET)

Detailed description:
I grabbed the CVS snapshot of 20011129, started with the BeOS GUI code found in
it, rewrote it totally (almost no original code left), and I now have a Bochs
that runs under BeOS quite nicely. New features compared to the BeOS GUI code
found in the above snapshot:

- color support in text mode (not perfect yet, but not BW at least)
- almost full keyboard capturing (modifier keys work, function keys also,
  keypad, arrow keys work, capslock doesn't work properly, numlock not at all.
  I need some help about how to tell Bochs to switch those properly)
- full mouse capturing, it works quite great!

Also see beos-gui-fabo.capture-filter and the associated README.

I updated this patch file to make it apply with the current CVS version. I have
added the cursor size and cursor hide feature for BeOS. The copy/paste functions
are still to do.
The capture filter works now - we have only the binary in this directory, but
not the source.

Patch was created with:
  diff -u
Apply patch to what version:
  gui/beos r1.16
Instructions:
  To patch, go to main bochs directory.
  Type "patch -p0 < THIS_PATCH_FILE".
