gtk/gdk/win32/gdkevents-win32.c
Tor Lillqvist 1acfb9ae12 Merge from gtk-2-0: 
2002-09-12  Tor Lillqvist  <tml@iki.fi>

	Merge from gtk-2-0:

	* gdk/win32/gdkevents-win32.c: Some spacing and indentation cleanup.

	* gdk/win32/gdkevents-win32.c (_gdk_events_init): Search if the
	system has some input locale identifier that uses a Latin
	keyboard. This is needed to be able to get the virtual-key code
	for the latin characters corresponding to ASCII control
	characters. If no such keyboard is present, try to load one
	then. Will this upset users with no wish to ever use a Latin-based
	keyboard layout?

	(vk_from_char): Convert all ASCII control chars to the
	corresponding uppercase char before calling VkKeyScanEx(). Idea by
	Florent Duguet. Makes Control-C work again. To make it hopefully
	work like I think it should on non-Latin keyboards, too, use
	latin_locale when looking for the corresponding keycode.

	Fix for #81831 by Tim Evans:

	* gdk/win32/gdkevents-win32.c (gdk_event_translate): Don't call
	_gdk_event_button_generate() here, it would append the double- or
	triple-click events too early, before the single-click event.

	(real_window_procedure): If we got a single-click event, call
	_gdk_event_button_generate() to perhaps append the double- or
	triple-click event after that.

	Merge from gtk-1-3-win32-production branch:

	* gdk/win32/gdkevents-win32.c (propagate): Check for parent being
	NULL before trying to propagate to it, and return FALSE in that
	case. (If parent is NULL, we are handling gdk_parent_root, and
	probably should have noticed that and bailed out earlier. But
	better late than never.)
