[vtkusers] vtkEventQtSlotConnect

[imran khan]

Hmmm.... that is weird as I can get mouse moves. Please see code below.

vtkEventQtSlotConnect *  connections = vtkEventQtSlotConnect::New();

..  connections->Connect(interactorROI,
                       vtkCommand::MouseMoveEvent,
                       this,
                       SLOT(handleMouseMove()));

..

// The slot
void myScene::handleMouseMove()
{
  // get event position
  int event_pos[2];
  interactorROI->GetEventPosition(event_pos);
  qDebug("Move: x=%d : y=%d\n", event_pos[0], event_pos[1]);
}



Unfortunately the mouse release of any button is still dysfunctional, which
is a travesty as this
is otherwise a very useful class. I wish someone would fix this.
