QGraphicsItem Question

Message 1 in thread

Hello All,
I've created a child class of QGraphicsItem (Qt v4.3.4).  I would like 
to override the
'mousePressEvent(QGraphicsSceneMouseEvent *event)' method since in 
QGraphicsItem
it's a protected virtual void.

Here is the declaration in my header file:

protected:
      void mousePressEvent(QGraphicsSceneMouseEvent *event);


Here is the simple test method from my cpp file:

void MosaicItem::mousePressEvent(QGraphicsSceneMouseEvent *event){
   std::cout << "Mouse Press Event" << std::endl;
 }

But when I click the mouse on my graphics items in the scene, I do not 
get the cout.
Any suggests as to what I'm doing wrong?

Thanks,
Stacy Alley

Also check QGraphicsView::setInteractive(..)

Thanks for the replies!  But I realized there was a flaw with the basic 
design on this class.
My bad!
