We currently calling gdk_display_map_keyval up to
once per key event per shortcut trigger, and that function
does an expensive loop over the entire keymap and
allocates an array. Avoid this by caching the entries
in a single array, and have a lookup table for finding
the entries for a keyval.
To do this, change the GdkKeymap.get_entries_for_keyval
signature, and change the ::keys-changed signal to be
RUN_FIRST, since we want to clear the cache in the class
handler before running signal handlers. These changes are
possible now, since keymaps are no longer public API.
GdkKeymap already has support for _get_num_lock_state() and
_get_caps_lock_state(). Adding _get_scroll_lock_state() would be good
for completness and some backends (Windows?) could take advantage of
this.
-Don't include unistd.h unconditionally as it's not available in Visual
Studio, but include io.h where necessary.
-Avoid C99isms, and use _chsize_s in place of ftruncate when unistd.h is
not available (as in the case of Visual Studio)
We can't really know the client side keymaps, so we use the keysym
as the hardware keycode (essentially claiming to have a keyboard with
one key for all possible keysyms). This is not ideal, but its hard to
do better with no knowledge of the client side keyboard mappings.
(And html keyboard events suck badly...)
This just runs:
for i in *.[ch]; do
sed -i s/DisplayX11/DisplayBroadway/g $i;
sed -i s/PrivateX11/PrivateBroadway/g $i;
sed -i s/ImplX11/ImplBroadway/g $i;
sed -i s/KeymapX11/KeymapBroadway/g $i;
sed -i s/ScreenX11/ScreenBroadway/g $i;
sed -i s/GdkX11Monitor/GdkBroadwayMonitor/g $i;
sed -i s/_X11/_BROADWAY/g $i;
sed -i s/x11/broadway/g $i;
done
