Layout issues, widgets get resized and unusable

[Radek]

The layout "centers" its items vertically so that they use the available space. The layout items do not get any margins. As to the first picture: the items seem to have too small vertical size. Check in Designer and make the vertical size bigger.

That does not seem to be exactly true, the widgets are at the top of the frame. There are a certain space between the widgets, and a lot of space after the last one (unless there are enough widgets to fill the vertical space). I don't have access to Qt Designer, I use the license free version.

So do I (using Linux). Please, post your .ui (the bad one).
