Question

When I have a QMainWindow with a grid layout, when resizing it with the mouse, it won’t go below some minimum size that’s necessary for all the controls in it to show properly. In my app I sometimes programatically hide controls, but then the window remains the same size and the rest of the controls look spread out, with too much space between them. I end up resizing the dialog manually so it doesn’t look ugly.

Can I programatically set the dialog’s vertical size to this minimum I get when manually resizing after I’ve hidden controls in it?

This code will do the trick (it resizes only the height):

    QWidget widget;
    widget.resize(widget.width(), widget.minimumHeight());
