It is simple
Here you are the relevant piece from some STAR GUI code

          Assuming you now (x,y) pixel on screen position 
          (Usually this is just a current cursor position) 
          where you want the menu to be popped up:

#include "TContextMenu.h"
....
TContextMenu *fContextMenu=0;
....

if (!fContextMenu) fContextMenu = new
TContextMenu("BrowserContextMenu");
TObject *obj = (TObject *)GetMyPointer(); if (obj) {

    fContextMenu->Popup(QCursor::pos().x(),QCursor::pos().y(), obj,(TBrowser *)0);
}
....

You can do that by connecting the relevant signal your custom slot.

Hope this helps,

Best Regards
