From b8bf751f9f5e2cb718175c0f2c4b2be762dcf614 Mon Sep 17 00:00:00 2001 From: Maxim Monastirsky Date: Tue, 23 Oct 2018 01:37:25 +0300 Subject: tdf#120764 Toolbar popups sometimes not showing under Wayland This happens with gtk 3.24 if the toolbar button is clicked when the tooltip of that button is visible. The warning gtk emits is "Tried to map a popup with a non-top most parent". The solution is to hide the tooltip early on mouse button press event processing. (gtk does hiding too, but in a way which isn't useful here - see the code comment. We also have similar code for the non-native case in ImplHandleMouseEvent of winproc.cxx.) Note that it's likely a gtk bug, as this new tooltip behavior breaks some native cases too, e.g. combo boxes with tooltips. But we can't leave our toolbars broken until this is fixed upstream.
