From d40acfcc33ae9f8d105f196d1af03a640a02db0b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?M=C3=A9ven=20Car?= Date: Wed, 18 Aug 2021 18:28:20 +0200 Subject: [PATCH] Wayland client: use wl_keyboard to determine active state Commit f497a5bb87270174b8e0106b7eca1992d44ff15d made QWaylandDisplay use the xdgshell's active state for QWindow::isActive(), instead of using wl_keyboard activate/deactivate events. That seems to have been a misunderstanding, since xdgshell activation is only supposed to be used to determine visual appearance, and there is an explicit warning not to assume it means focus. This commit reverts this logic back to listening to wl_keyboard. It adds a fallback when there is no wl_keyboard available to handle activated/deactivated events through xdg-shell, in order to fix QTBUG-53702. windowStates is handled so that we're not using the Xdg hint for anything with QWindowSystemInterface::handleWindowStateChanged or anything where we need to track only having one active. We are still exposing it for decorations, which is the only reason to use the Xdghint over keyboard focus - so you can keep the toplevel active whilst you show a popup. cherry-pick 40036a1b80e5234e6db7d5cbeff122aa7ee13e20 Change-Id: I4343d2ed9fb5b066cde95628ed0b4ccc84a424db Reviewed-by: Eskil Abrahamsen Blomfeldt --- src/client/qwaylanddisplay.cpp | 19 +++++++++++-------- src/client/qwaylanddisplay_p.h | 1 + src/client/qwaylandwindow.cpp | 13 +++++++++++-- src/client/qwaylandwindow_p.h | 1 + .../qwaylandshellintegration_p.h | 7 +++---- .../qwaylandxdgshellv5integration.cpp | 7 ------- .../qwaylandxdgshellv5integration_p.h | 1 - .../qwaylandxdgshellv6integration.cpp | 14 -------------- .../qwaylandxdgshellv6integration_p.h | 1 - .../xdg-shell/qwaylandxdgshell.cpp | 16 +++++----------- .../xdg-shell/qwaylandxdgshellintegration.cpp | 14 -------------- .../xdg-shell/qwaylandxdgshellintegration_p.h | 1 - tests/auto/client/xdgshell/tst_xdgshell.cpp | 10 +++++++--- 13 files changed, 39 insertions(+), 66 deletions(-) --- a/src/client/qwaylanddisplay.cpp +++ b/src/client/qwaylanddisplay.cpp @@ -579,14 +579,10 @@ void QWaylandDisplay::handleKeyboardFocusChanged(QWaylandInputDevice *inputDevic if (mLastKeyboardFocus == keyboardFocus) return;
