Merge from stable: 2003-12-14 Tor Lillqvist <tml@iki.fi> Merge from stable: * gdk/gdkdisplaymanager.c: Mark default_display static. * gdk/win32/gdkdnd-win32.c: Mark current_dest_drag static. * gdk/win32/gdkkeys-win32.c: Disable some overly verbose debugging output. * gdk/win32/gdkevents-win32.c: Clean up the debugging output from --gdk-debug=events. In general, output just one line of debugging output for each Windows message, plus one line for each GDK event generated. Indent all lines according to window procedure nesting level. (inner_window_procedure): Rename from real_window_procedure. (find_real_window_for_grabbed_mouse_event): Don't get misled when the point is in the non-client (decoration) area of the window returned by WindowFromPoint(). Return the root window in that case. (build_pointer_event_state): Test also MK_XBUTTON1 and MK_XBUTTON2 (buttons 4 and 5). (synthesize_enter_event): Track the mouse leaving the window in the event being generated, not the one mentioned in the Windows message. (propagate): Test for NULL parent earlier. Improves event generation from a grabbed pointer. Part of fix for #107320. (handle_stuff_while_moving_or_resizing): New function, to dispatch the main loop (once). (resize_timer_proc): New function, set to be called by an inerval timer during resizes/moves. Calls handle_stuff_while_moving_or_resizing(). (gdk_event_translate): Drop unused return_exposes parameter. Handle WM_XBUTTONDOWN and UP messages (buttons 4 and 5). On WM_SYSKEYUP, generate a key release event also for just the Alt key. On WM_MOUSELEAVE, generate a leave event of type GDK_NOTIFY_ANCESTOR (and not UNKNOWN) if the mouse left a top-level window, and left the app completely. On WM_ENTERSIZEMOVE, set a flag, and start an interval timer that calls resize_timer_proc() at regular intervals. On WM_EXITSIZEMOVE, kill the timer. On WM_WINDOWPOSCHANGED, generate a configure event if necessary, and dispatch the main loop (by calling handle_stuff_while_moving_or_resizing()). Fixes #99540, idea by Herman Bloggs. * gdk/win32/gdkmain-win32.c (_gdk_win32_message_to_string): Handle also wintab messages. * gdk/win32/gdkwindow-win32.c (gdk_window_set_skip_taskbar_hint): Instead of using WS_EX_TOOLWINDOW, implement by setting/unsetting the window's owner. Fixes #118093, reported by Maxime Romano.
