Hi,

I'm using two Dockwidgets one left one right, each docked. I'd like to have them both docked without filling the whole vertical space. When i change their size it shows only effect when non docked, so i tried to make their background transparent.
I tried

  • setBackgroundRole(QPalette::NoRole);
  • setWindowOpacity (0.5);
  • setAttribute(Qt::WA_TransparentForMouseEvents);
  • setAttribute(Qt::WA_TranslucentBackground);
  • and the setBrush on the background which just drawed the background black instead of transparent when non docked


and the setMask code from
t-qdialog-w-transparent-backgroundl

but none of it worked

is there any other possibility to adjust the size of a docked widget or setting its transparent?
