D18410: Implement PlasmaShellSurface::popupBehavior in kwin

davidedmundson added a comment.


  The default state works fine without tricks.
  
  There's a magic button on the system tray/calendar with a little icon of a pin. When clicked this window should remain on top even when focus goes to somewhere else. This is unlike a normal popup.
  
  Currently this is done via QWindow::setFlags(Qt::WindowStaysOnTopHint) which on the wayland QPA goes nowhere.
  
  Somehow we need to negotiate whether we're in that mode or the normal mode.
