From d533901938a996367d7b6f87b0214f5a17098aed Mon Sep 17 00:00:00 2001 From: Jan Grulich Date: Tue, 23 Mar 2021 16:03:22 +0100 Subject: [PATCH] Client: expose toplevel window state QWaylandWindow has only basic information about window state, like if it's active or maximized, but it has no information about tiling, which can be useful for client-side decorations. We also need to bump version of xdg-shell protocol we support, because additional states are not in the version currently supported by QtWayland. It shouldn't be a problem to increase the version as the new version adds just these additional window states.
