    XMLWordPrintable

Details

    • Linux/X11
    • f9e4402ffeef791e66b7b2f2cc332000df7f5cd4 f302a224fa (qt/tqtc-qtbase/6.3) ecfcb72756 (qt/tqtc-qtbase/6.2) 290b405872 (qt/qtbase/5.15)

    Description

      setting the flag Qt::WindowStaysOnTopHint at runtime does not always work if it works then unsetting same flag still shows windows on top. 

      Some time the widget will not stay on top, although the flag is set.  It will disappear when click outside the application, or can be overlapped (z-order) by another widgets. 

      This can be easily reproducible with Qt's windowflags example:
