My application consists of a WebView widget. A mouse click on the widget is not handled by the mousePressEvent() of my application, but by the WebView widget. So, I installed an event filter to receive the events. Now, I get notified of all events, except the mouseReleaseEvent for the right click (Everything works fine for left clicks and mousePressEvent for the right click is also getting registered). I guess it has got something to do with context events getting generated by right clicks (a pop-up menu gets generated). But since I am using a filter, the event should first be sent to me. The following is the code for the event filter

Qt Code: 
  1. public boolean eventFilter(QObject o,QEvent event)
  2. 	{
  3. 		if (event.type()==QEvent.Type.MouseButtonPress)   // One can call the mousePressEvent() functions from here,which can do this work but speed
  4. 		{
  5. 			if (((QMouseEvent)event).button()==Qt.MouseButton.LeftButton)
  6. 			{
  7. 				mousebuttontype=1;
  8. 				clickedorpressed=1;
  9. 			}
  10. 			else
  11. 			if (((QMouseEvent)event).button()==Qt.MouseButton.RightButton)
  12. 			{
  13. 				mousebuttontype=2;
  14. 				System.out.println("right");
  15. 			}
  16. 			t1=QTime.currentTime();
  17. 			t1.start();
  18. 		}
  19. 		else
  20. 		if (event.type()==QEvent.Type.MouseButtonRelease)
  21. 		{
  22. 			if (t1.elapsed()>900)
  23. 			{
  24. 				switch(mousebuttontype)
  25. 				{
  26. 					case 1:	browser.back();
  27. 						break;
  28. 					case 2:	browser.forward();
  29. 						break;
  30. 				}	
  31. 			}System.out.println("choda");
  32. 		}	
  33.  
  34. 		return false;
  35. 	}
To copy to clipboard, switch view to plain text mode 

On a right click, I get the message "right" but on releasing, I don't get "choda". I get both the messages for left clicks.
