QGraphics View

[Vivek1982]

Dear All,

I have developed a application using QGraphicsScene and QGraphicPixmapItem. In the application I'm adding pixmaps on the graphic scene. Initially I'm inserting
Pixmap based on timer event for 1 seconds. On the same scene I need to insert second pixmap manually by pushbutton event. Im sharing the code here.plz help me, where I'm making mistake. I have attached output screen shot also.

SERVER::SERVER(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::SERVER)
{
    ui->setupUi(this);
 
        scene=new QGraphicsScene(0,0,740,400);
        scene=new QGraphicsScene(ui->graphicsView);
 
int x=50;
int y=50;
 
timer.start(1000);
 
//other declarations line edit, push buttons
}
 
void SERVER::timeout_123()
{
 
    x=x+2;
    y=y+2;
    QPixmap pix(":/t23_1.png");
    QGraphicsPixmapItem *pix1= scene->addPixmap(pix);
    ui->graphicsView->setScene(scene);
    pix1->setPos(x,y);
 
 
}
 
void SERVER::on_pushButton_clicked()
{
    qDebug("inserting new item");
     QPixmap pix2(":/pin30_red.png");
    QGraphicsPixmapItem *GIpix2= scene->addPixmap(pix2);
    ui->graphicsView->setScene(scene);
   GIpix2->setPos(650,150);
 
}

SERVER::SERVER(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::SERVER)
{
    ui->setupUi(this);
        
        scene=new QGraphicsScene(0,0,740,400);
        scene=new QGraphicsScene(ui->graphicsView);

int x=50;
int y=50;

timer.start(1000);

//other declarations line edit, push buttons
}

void SERVER::timeout_123()
{

    x=x+2;
    y=y+2;
    QPixmap pix(":/t23_1.png");
    QGraphicsPixmapItem *pix1= scene->addPixmap(pix);
    ui->graphicsView->setScene(scene);
    pix1->setPos(x,y);


}

void SERVER::on_pushButton_clicked()
{
    qDebug("inserting new item");
     QPixmap pix2(":/pin30_red.png");
    QGraphicsPixmapItem *GIpix2= scene->addPixmap(pix2);
    ui->graphicsView->setScene(scene);
   GIpix2->setPos(650,150);

}

If i compile this code, initial timer based pixmap and pushbutton clicked pixmap will loaded onto the scene. In the Timer event Im incrementing setPos coordinated by 2 for every 1 second. Here on the scene, timer based pixmap is getting shifting in position but clear movement of image is not there somewat blurred.Any problem in the decalration?

Thanks in Advance.
