PySide2 and Qt Designer: unable to make QGroupBox expand in runtime
I'm a Tkinter user, but I decided to use Qt library, 'cause the final result is more pro. I'm re-coding an old interface, that is populated in runtime based on the contents of an ini file.
IMG starting point:
But when I do it, the news widgets almost stack ones over the others. If I expand the window manually, the widgets use all the vertical space, but I tried to make them to stay in the top of window.
IMG populated:
,
IMG manually resized (only vert allowed):
That's the Qt Designer UI:
That's the complete code generated by QTD:

I use abbrevs in the name of the widgets to easilly identify and search them in Pycharm structure: WDT - widget, BTN - button., LBL - label, GRB - groupbox, VLS - vertical spacer, HZS - horizontal spacer.
I have tried a lot of solutions, but almost all are about use Qt Designer auto layouts, and I'm doing from scratch.

I post it like answer, to help someone else with the same problem. Easier to find than buried between 20 comments. @musicamante have the solution:
Try resetting the minimum size property of the main window (be careful: you should not set it to 0, but actually reset it by clicking the small red arrow). Setting a minimum dimension does not only ensure that the widget has a minimum size, but also tells its layout that the contents may be stretched in order to allow that minimum size.
Thanks!
if @musicamante publish the answer, I'll delete this message and vote it like OK.
