How set size policy

[erytcg]

Hello my mainwindow looks like this:

I would like to auto resize "Widget" with resize window and don't change size of tabWidget and GroupBoxes.
How to set size policy this widget to this effect?

Hi,

I think that you just want to keep both tabWidget and GroupBoxes to fixed size

In qt designer there is a property called sizePolicy ,

SizePolicy must be preferred for QWidget (preferred is the default value)
SizePolicy must be fixed for QGroupBoxes and tabWidget

And window in GridLayout?

I am not sure i understand what you want,? window has also a sizePolicy

It dosn't work when I resize window all is on left corner

@erytcg It looks like your main window does not have a layout...
