There's another option, but *only* if you built Qt in debug mode. Run the 
application with the -nograb option. Then you can tab out of the menu and use 
ksnapshot to screenshot the application.

The reason you're having problem is because menus and any kind of popup grab 
the X server, to make sure that it disappears when you click somewhere else. 
So you can't have a menu shown and tab out of the application. However, the -
nograb option disables that grabbing.

But the -nograb option is only available in debug builds of Qt, since it's 
meant for testing applications. If you're running your app in the debugger, -
nograb is the default, even, since your application may stop execution while a 
popup is shown.

If the application stops execution with the X server grabbed, you can't click 
anywhere.
