title: Qt gui creation, widget resizing
body: <p>I am new to Qt development, even though I have years of MFC programming. I am trying to create a dockable widget and put some controls in the dock widget, a tab widget to be more precise. My problem is that the tab widget inside the dock widget doesn't resize along with the parent.</p>
  
  <p>I'd like the tab widget to fill the entire area of the dock widget. Is it possible to manipulate some property in the same gui designer?</p>
