QDockWidget & sizepolicy size with scroll area...

[Dariusz]

Hey

I'm trying to set a size policy of my dockWidget to have stretch of factor 2+. So that I know this widget will always try to force its size to be wider than others... I'm a bit stuck as to which size I have to adjust? It seems that chaning them does not do anything much ?

I also don't know how to hide central widget in designer...sigh. Still any ideas?
