X11: cannot programmatically minimize a frameless window

    XMLWordPrintable

Details

    Description

      If you make a frameless window with setWindowFlags(Qt::FramelessWindowHint);
      then in qxcbwindow.cpp, MWM_FUNC_MINIMIZE is not set. In some window managers, that means you cannot minimize the window. This is relevant for applications that wish to forego the window manager titlebar and have a custom one instead.

      http://comments.gmane.org/gmane.comp.desktop.mate.devel/125

      The workaround is to set

      setWindowFlags(Qt::FramelessWindowHint | Qt::WindowMinimizeButtonHint)

      An example of an app which does this is here:
