Hold the dWidget variable beyond the scope of whatever function it is 

i.e. -- when the widget goes away, it does not show up anymore. You 
need to hold the reference alive by maintaining a smart pointer to it 
at a "more outer" scope. Perhaps attaching it to whatever keeps your 
renderwindow alive makes sense...
