Hi,

I've tried to apply QGraphicsBlurEffect to my QGraphicsPixmapItem, but after doing so, my item disappears form the scene!

Thats the code i've used:

Qt Code: 
  1. Player* player(playerImage);
  2.     scene.addItem(player);
  3.  
  4.     QGraphicsBlurEffect* blur = new QGraphicsBlurEffect;
  5.     player->setGraphicsEffect(blur);
To copy to clipboard, switch view to plain text mode 

here's Player class:

player.h
Qt Code: 
  1. #ifndef PADDLE_H
  2. #define PADDLE_H
  3.  
  4. #include <QGraphicsItem>
  5.  
  6. class Player : public QGraphicsPixmapItem
  7. {
  8. public:
  9.     Player(QPixmap* _image);
  10.  
  11.     QRectF boundingRect() const;
  12.     QPainterPath shape() const;
  13.     void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget);
  14.  
  15.     QPixmap image;
  16. };
  17.  
  18. #endif // PADDLE_H

player.cpp
Qt Code: 
  1. #include <QPainter>
  2.  
  3. #include "player.h"
  4.  
  5.  
  6. Player::Player(QPixmap* _image)
  7. {
  8.     image = _image->scaled(QSize(100,100),Qt::KeepAspectRatio);
  9. }
  10.  
  11. QRectF Player::boundingRect() const
  12.  {
  13.      return image.rect();
  14.  }
  15.  
  16.  QPainterPath Player::shape() const
  17.  {
  18.      QPainterPath path;     
  19.      path.addRect(image.rect());
  20.      return path;
  21.  }
  22.  
  23.  void Player::paint(QPainter *painter, const QStyleOptionGraphicsItem *, QWidget *)
  24.  {
  25.      painter->drawPixmap(-image.rect().width(),-image.rect().height(),image);
  26.  }

What should I do?
