Sprite animation with SVG sprite sheet in Qt Graphics View

Recently I started to port my game to Symbian platform,
In my previous post I showed how to make graphics work with different resolution.But if you are using images in application, you need to use SVG image to make sure that images looks good in all resoltion.

When I started to replace my game images with SVG image, I need to make changes in my sprite class.With normal images I was drawing only certain portion of image from Sprite sheet like code in this post, but I could not make that thing work with SVG. Then to make my sprite class work I made following changes.

In following code, I am using SVG file which contain each frame with unique id and in code on next frame I am rendering SVG element with id for particular frame.

Code for animatedsvgitem.h

#ifndef ANIMATEDSVGITEM_H
#define ANIMATEDSVGITEM_H

#include <QGraphicsSvgItem>
#include <QTimer>

class AnimatedSvgItem : public QGraphicsSvgItem
{
    Q_OBJECT
public:
    AnimatedSvgItem();
    QRectF boundingRect() const;

private slots:
    void nextFrame();

private:
    QTimer *timer;
    QStringList frames;
    int currentFrame;
};
#endif // ANIMATEDSVGITEM_H

Code for animatedsvgitem.cpp

#include "animatedsvgitem.h"

AnimatedSvgItem::AnimatedSvgItem()
    :QGraphicsSvgItem( QString(":/egg.svg") )
{
    //svg element id of frame in svg file
    frames << "egg1" << "egg2" << "egg3" << "egg4" << "egg5" << "egg6" << "egg7" << "egg8";
    currentFrame = 0;
    this->setElementId( frames[currentFrame] );
    timer = new QTimer(this);
    QObject::connect(timer,SIGNAL(timeout()),this,SLOT(nextFrame()));
    timer->start(400);
}

QRectF AnimatedSvgItem::boundingRect() const
{
    return QRectF(0,0,20,20);
}

void AnimatedSvgItem::nextFrame()
{
    currentFrame = ++currentFrame % 8;
    this->setElementId( frames[currentFrame]);
    this->moveBy(5,0);
    update();
}

So this was all, Sprite sheet used for above code is like this but in SVG format.

Here video from sample code.
