[osg-users] How can I know the number of GUIEventAdapter::USER in the message queue for GUIEventHandler?

[OpenSceneGraph Users]

I Send  USER  events  loading model  from qt . Is this the right approach?  

I want the progress bar in the QT to show that the  model  is loaded. So, 
Check whether USER evnet has been processed completely.

Are there any good Suggestions?
