Layout Problem

[sabonis]

When I use a vboxlayout , even if I use all margins and spacings = 0, there is a space between the bottom layout margin and the bottom widget. I don't want this space! How can I Fix?

Perhaps you have nested layouts and you didn't disable the margin for each layout or something. Could you attach the .ui file?

Thank you for reply, I can't post the ui file .
The vboxlayout is contained in a hboxlayout (the layout of the mainwindow), but the problem presents itself even before I set the hboxlayout. Moreover is visible that the EVIL BOTTOM MARGIN is between the red bottom bound of the vboxlayout and the bottom of the bottom widget.

We don't need the original .ui file. Just prepare small example which shows the problem.

Problem solved.
There was an invisible label!
