2001-06-04 William M. Perry <wmperry@gnu.org>
* gpmevent.c (KG_CTRL): Just define these unconditionally. The
linux headers are so lame that they do not expose these to
userland programs and you cannot gracefully include the kernel
headers.
2001-06-03 William M. Perry <wmperry@gnu.org>
* scrollbar-gtk.c (gtk_create_scrollbar_instance): Make calling of
gtk_size_request unconditional.
2001-06-02 William M. Perry <wmperry@gnu.org>
* emacs-marshals.c: Regenerated.
2001-06-01 William M. Perry <wmperry@gnu.org>
* glyphs-shared.c (read_bitmap_data): Common definition of
read_bitmap_data_from_file added. This does not attempt to use
the Xmu based code at all - lets us be consistent across
platforms.
* glyphs-gtk.c: Removed definition of read_bitmap_data_from_file -
this is now in glyphs-shared.c
* glyphs-msw.c: Ditto.
* glyphs-x.c: Ditto.
2001-06-03 William M. Perry <wmperry@gnu.org>
* dialog-gtk.el (popup-builtin-open-dialog): Yikes - don't forget
to return the filename!
* font.el (font-window-system-mappings): Add gtk entry - just an
alias to the X code)
2001-06-02 William M. Perry <wmperry@gnu.org>
* gtk-marshal.el: Fix for removing of the string_hash utility
functions in hash.c
