title: How can I change the width of a QMainWindow separator without it affecting the QDockWidget
body: <p>I have a QDockWidget which has been added to a QMainWindow.  I set the sizeHint of the DocWidget to be 260px and its the size that I want it to be because nothing else is offering up a size.</p>
  
  <p>However now I want to increase the width of the DockWidget - QMainWindow separator.  The only way I have found of doing this is via a StyleSheet:</p>
  
  <p><a href="http://doc.qt.nokia.com/4.7-snapshot/stylesheet-examples.html#customizing-qmainwindow" rel="nofollow">http://doc.qt.nokia.com/4.7-snapshot/stylesheet-examples.html#customizing-qmainwindow</a></p>
  
  <p>However when I do this the DockWidget shrinks to &lt; 100px and becomes unusable.  You cannot force the QDockWidget to a certain size and its inheriting the MainWindows stylesheet.</p>
  
  <p>I also cannot get any other handle on the QMainWindow::separator.</p>
