I work on creating a tool for maya with pyqt4.  
And in my tool, there is some menus on QMenuBar.  
In that situation, I hope to create a menu + option menu style like above image.  
As you see there is "New Scene" menu and square icon at the right side of "New Scene".  
If I select just "New Scene", it works as creating a new scene.  
And if I select square icon of "New Scene", it pops up option window for creating a new scene.  
That's the one I hope to do.  
How can I do this?
