* xcb: Fix available geometry after rotationAlexander Volkov2020-12-132-5/+10
QXcbVirtualDesktop::m_workArea is not updated after screen rotation if _NET_WORKAREA is not updated, e.g. when a window manager is not running. Use width of -1 for m_workArea to indicate that _NET_WORKAREA is not set and thus there is no need to find its intersection with screens' geometries.

* Allow to prevent blocking of native dialogs by a proxy Qt dialogAlexander Volkov2018-10-023-0/+32
When native dialogs become visible, their invisible proxy Qt dialog blocks input to Qt windows. It is intended for native dialogs which can't block Qt windows themselves, e.g. on Android.

This change introduces QPlatformDialogHelper::DialogIsQtWindow style which allows to detect such cases and prevent blocking.
