Answer 1

On Object which one you want to restrict apply these flags based on requirement

    setMaximumWidth(Default_width);
    setMaximumHeight(Default_height);

Answer 2

You could override the event method (or https://doc.qt.io/Qt-5/qwidget.html#mouseMoveEvent), check for a MouseMove event and accordingly limit the maximum horizontal size of the dialog.
