title: Overlapping widgets in QtDesigner
body: <p>I want to overlay two widgets in QtDesigner:
  There is the big QTextBrowser, and below in the down right corner should be a non-interactiv label that I am going to use as a drag-grip to resize the window (the main widget is frameless so I need to implement it).
  Usually this label will sit below the QTextBrowser, which leaves on the left of the grip-label a lot of unused space. So I want to put the grip-label above the QTextBrowser. I want to achieve this in QtDesigner. But the code would look like:</p>
  
  <pre><code>QHBoxLayout *layout = new QHBoxLayout(videoWidget);
  QLabel *overlayWidget = new QLabel();
  overlay-&gt;setAlignment(Qt::AlignCenter);
  overlay-&gt;setText("Overlaid Text");
  layout-&gt;addWidget(overlay); 
  </code></pre>
  
  <p>Or as I already did in python:
      self.textedit = QTextBrowser(self);
      ...
      gripImage=QLabel(self.textedit);</p>
  
  <p>There the part between the brackets is the parent widget.</p>
  
  <p>That's how it looks right now, but this is not what I want:</p>
