Keyboard input in custom QQuickPaintedItem

kimoren

As you can see code is really simple. Rectangle is successfully drawn on the screen, but pressing arrows does nothing. Is this a wrong method? If so, how can I process the keyboard input?

Here are some parts of the code:
(rest of the code is constructor that does nothing and a few useless functions)

class NiceItem : public QQuickPaintedItem
{

  ...

  public:

    ...

    void keyPressEvent(QKeyEvent * event);
    void paint(QPainter *painter);

  ...

};

void NiceItem::keyPressEvent(QKeyEvent * event)
{

  if(event->key() == Qt::Key_Left)
    playerX--;
  else if(event->key() == Qt::Key_Right)
    playerX++;
  else if(event->key() == Qt::Key_Up)
    playerY--;
  else if(event->key() == Qt::Key_Down)
    playerY++;

}

void NiceItem::paint(QPainter *painter)
{

  QPen pen(m_color, 2);
  painter->setPen(pen);

  QRectF rectangle(playerX, playerY, 80.0, 60.0);
  painter->drawRect(rectangle);

  update();

}

I already solved the problem. It was enough to set focus to this item in constructor as following:

setFlag(QQuickItem::ItemIsFocusScope, true);
setFocus(true);
