- Shorten menu code, add keyboard shortcuts and a quit action. - Avoid calls to setLayout(). - Pass a parent to message boxes. - Use the current screen for size calculation and consider availableGeometry(). - Prevent closing by the Escape key in docked mode. - Split the dockUndock() function into dock()/undock() for clarity Change-Id: I007da3bff86ee3f2dc8f87379e5d2ba2f0f6f3d7 Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io> (cherry picked from commit 6f8398c8eb5476a6e98126d5b63421896b874271) Reviewed-by: Qt Cherry-pick Bot <cherrypick_bot@qt-project.org> (cherry picked from commit 734db610c3db3f00775d518b63d94695a2654389)
