title: Cocoa QTMovieView keydown not working
body: <p>I have a QTMovieView control on my cocoa window and it's working great with movies.</p>
  
  <p>Now I want to intercept key down / up events to control the video as I like. </p>
  
  <p>I created a MyMovieView class derived from QTMovieView like this</p>
  
  <pre><code>@interface MyMovieView : QTMovieView
  
  -(BOOL)acceptsFirstResponder;
  -(void)keyDown:(NSEvent*)theEvent;
  
  @end
  </code></pre>
  
  <p>and the code that implements it.</p>
  
  <p>I tried to insert the class name "MyMovieView" into the "Custom Class" field of the Interface Builder inspector for the control QTMovieView but seems like after I close the interface builder, the class gets lost and the "Custom Class" field doesn't remember MyMovieView class.</p>
  
  <p>Am I getting something wrong with the subclass mechanism? I'm a Cocoa newbie</p>
