Multi screen support using XCB and VNC.

[cnu.1439]

Hi,
I'm trying to run my application on multiple screens using XCB platform plugin. I'm able to see the application on multiple vnc sessions but there is a problem with drag and drop and context menu.
Drop event is happening only on one screen irrespective of the screen hosting the widget with draggable item. Its the same case with context menu. Its showing on one screen even if I'm doing right click on other screen.

Sample application: draggableicons

  How to run:
       * Run 2 vnc sessions
              $ vncserver :1
              $ vncserver :2
       * Run application using xcb platform
              $ <build directory>/draggableicons -platfom xcb::2 -display :1

Im using Qt5.9.2 on Ubuntu 16.04.
Please guide me in right direction to solve this.

Thank You.
Srinivas.
