Hi there,

I'm trying for half an eternity now overriding QWidgets keyPressEvent function in QT but it just won't work. I've to say i am new to CPP, but I know ObjC and standard C.

My problem looks like this:

class QSGameBoard : public QWidget {
Q_OBJECT

public:
  QSGameBoard(QWidget *p, int w, int h, QGraphicsScene *s);

signals:
  void keyCaught(QKeyEvent *e);

protected:
  virtual void  keyPressEvent(QKeyEvent *event);
};

QSGameBoard is my QWidget subclass and i need to override the keyPressEvent and fire a SIGNAL on each event to notify some registered objects.

My overridden keyPressEvent in QSGameBoard.cpp looks like this:

void QSGameBoard::keyPressEvent(QKeyEvent *event) {
  printf("\nkey event in board: %i", event->key());
  //emit keyCaught(event);
}

When i change QSGameBoard:: to QWidget:: it receives the events, but i cant emit the signal because the compiler complains about the scope. And if i write it like this the function doesn't get called at all.

What's the problem here?
