event handling...

[xyzt]

I have a simple class inherits QGraphicsRectItem class. I want it to write "testing" in the mousePressEvent() but it doesn't...where am i doing wrong?i examined the tutorials but couldn't find my fault...

QGraphicsScene scene(0,0,200,200);    
    scene.addItem(new MyItem(0));
    QGraphicsView view(&scene);
    view.show();
    return a.exec();

QGraphicsScene scene(0,0,200,200);    
    scene.addItem(new MyItem(0));
    QGraphicsView view(&scene);
    view.show();
    return a.exec();

You need to make your item selectable. Add the following line to the MyItem constructor:

setFlags(QGraphicsItem::ItemIsSelectable);

setFlags(QGraphicsItem::ItemIsSelectable);
