I use QtDesigner. I resized window width as small as possible using QtDesigner. But when window executed there is possible to make its width smaller. So I want to add to constructor code which made width as minimum possible using GUI.
You can resize
the window to minimumSizeHint()
in the constructor:
resize(minimumSizeHint());
This will shrink the window to minimum size.
If you want to only shrink in width, then you can do something like:
resize(minimumSizeHint().width(), hight());
