Unsolved QtDesigner: Trick for drop a widget in a zero sized layout ?

[Andy314]

Hello, I have always the following problem with the designer:

I have a Dialog with a least on widget with a MinimumExpanding, that mean it take as much space as possible. Then I want an additional layout in the dialog. I drop a layout and it gets 0 height or width (depending on its parent layout).
Therefore it is not possible to drop a new widget in it. Is there a trick to reach this ?

Because of this problem I never use layouts directly, I take Frames, increment its minimum size temporary, drop in a widget, set its layout and reset its minimum size.

Yeah, it's kinda annoying. What I usually do is set one of the layout's margins, drop the widget and then reset the margin.
I wouldn't use an extra widget just for that.
