Hello forum


I have the following class memeber functions that tries to capture the key press and release events, but none of them is captured.


Qt Code: 
  1. class DiagramScene : public QGraphicsScene
  2. {
  3.     Q_OBJECT
  4.  
  5. public:
  6.     enum Mode { InsertItem, InsertLine, InsertText, MoveItem };
  7.  
  8.     DiagramScene(QMenu *itemMenu, QObject *parent = 0);
  9.     QFont font() const
  10.         { return myFont; }
  11.     QColor textColor() const
  12.         { return myTextColor; }
  13.     QColor itemColor() const
  14.         { return myItemColor; }
  15.     QColor lineColor() const
  16.         { return myLineColor; }
  17.     void setLineColor(const QColor &color);
  18.     void setTextColor(const QColor &color);
  19.     void setItemColor(const QColor &color);
  20.     void setFont(const QFont &font);
  21.  
  22. public slots:
  23.     void setMode(Mode mode);
  24.     void setItemType(DiagramItem::DiagramType type);
  25.     void editorLostFocus(DiagramTextItem *item);
  26.  
  27. signals:
  28.     void itemInserted(DiagramItem *item);
  29.     void textInserted(QGraphicsTextItem *item);
  30.     void itemSelected(QGraphicsItem *item);
  31.  
  32. protected:
  33.     void mousePressEvent(QGraphicsSceneMouseEvent *mouseEvent);
  34.     void mouseMoveEvent(QGraphicsSceneMouseEvent *mouseEvent);
  35.     void mouseReleaseEvent(QGraphicsSceneMouseEvent *mouseEvent);
  36.  
  37.     void keyReleaseEvent(QKeyEvent *event);
  38.     void keyPressEvent(QKeyEvent *event);
  39.  
  40. private:
  41.     bool isItemChange(int type);
  42.  
  43.     DiagramItem::DiagramType myItemType;
  44.     QMenu *myItemMenu;
  45.     Mode myMode;
  46.     bool leftButtonDown;
  47.     QPointF startPoint;
  48.  
  50.  
  51.     QFont myFont;
  52.     DiagramTextItem *textItem;
  53.     QColor myTextColor;
  54.     QColor myItemColor;
  55.     QColor myLineColor;
  56. };
To copy to clipboard, switch view to plain text mode 

Qt Code: 
  1. void DiagramScene::keyPressEvent(QKeyEvent *event)
  2. {
  3.     if(event->key() == Qt::Key_Control)
  4.     {
  5.         std::cout << "Ctrl pressed" << endl;
  6.     }
  7. }
To copy to clipboard, switch view to plain text mode 


Any hint on this?
