From 9990f1ac294300ca1e5839cb4e168e285eb9d122 Mon Sep 17 00:00:00 2001 From: Chun-wei Fan Date: Tue, 6 Oct 2020 15:06:47 +0800 Subject: GDK/Win32: Fix modal window handling Make sure that we get the state of the modal window properly, and send out the corresponding notification signals. This will ensure that we do not try to activate windows that should have become inactivated due to it opening modal windows and render the program unresponsive because we are not activating the correct window that is due to receive user input. --- gdk/win32/gdksurface-win32.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/gdk/win32/gdksurface-win32.c b/gdk/win32/gdksurface-win32.c index 3e9de289bd..2ef43845b8 100644 --- a/gdk/win32/gdksurface-win32.c +++ b/gdk/win32/gdksurface-win32.c @@ -4825,7 +4825,12 @@ gdk_win32_toplevel_set_property (GObject *object, break; case LAST_PROP + GDK_TOPLEVEL_PROP_MODAL: - _gdk_push_modal_window (surface); + GDK_SURFACE (surface)->modal_hint = g_value_get_boolean (value); + + if (GDK_SURFACE (surface)->modal_hint) + _gdk_push_modal_window (surface); + + g_object_notify_by_pspec (G_OBJECT (surface), pspec); break; case LAST_PROP + GDK_TOPLEVEL_PROP_ICON_LIST: @@ -4879,6 +4884,7 @@ gdk_win32_toplevel_get_property (GObject *object, break; case LAST_PROP + GDK_TOPLEVEL_PROP_MODAL: + g_value_set_boolean (value, GDK_SURFACE (surface)->modal_hint); break; case LAST_PROP + GDK_TOPLEVEL_PROP_ICON_LIST: -- cgit v1.2.1
