Custom QGraphicsRectItem does not respond to key events

MadMan27

I have created a class called MyRect that derives from QGraphicsRectItem. I overided the keyPressEvent to just print out a message. I put my rect item in a scene, set its itemisfocusable flag, and called it's setFocus() method. However, when I press keys, my item's keyPressEvent() method does not run. What is wrong? Here is the code:

==main.cpp==
@#include <QApplication>
#include "MyRect.h"
#include <QGraphicsScene>
#include <QGraphicsView>

#include <QDebug>
int main(int argc, char *argv[]){
QApplication a(argc, argv);

// create a scene
QGraphicsScene * scene = new QGraphicsScene();

// create an item to add to the scene
MyRect * rect = new MyRect();
rect->setRect(0,0,100,100); // change the rect from 0x0 (default) to 100x100 pixels

// add the item to the scene
scene->addItem(rect);

// give the item focus
rect->setFlag(QGraphicsItem::ItemIsFocusable,true);
rect->setFocus();

// create a view to visualize the scene
QGraphicsView * view = new QGraphicsView(scene);

// show the view
view->show();

return a.exec&#40;&#41;;

}

==MyRect.h==
@#ifndef MYRECT_H
#define MYRECT_H

#include <QGraphicsRectItem>
#include <QKeyEvent>

class MyRect: public QGraphicsRectItem{
public:
MyRect();
void keyPressEvent(QGraphicsSceneEvent *event);
};

#endif // MYRECT_H@

==MyRect.cpp==
@#include "MyRect.h"

#include <QDebug>
MyRect::MyRect(): QGraphicsRectItem(){

}

void MyRect::keyPressEvent(QGraphicsSceneEvent *event){
qDebug() << "my rect knows you pressed a key! :D";
}
