QPixmap not getting resized with scaled()

[DURGAPRASAD NEELAM]

hai, i am resizing the image with scaled function, but it is beeing with the ame size only. i want to decrese size of the image, so that they will take less memory.
i am displaying 1000 images on scene so it is taking more memory because of ths issue. how i have to reduce the sie of Qimage and display them on scene as a thumbnile .

QImage image = tempImage;	              // is 1025*724 
    image.scaled(50,50,Qt::KeepAspectRatio);  
    item = new QGraphicsPixmapItem(QPixmap::fromImage(image));
    scene->addItem(item);

QImage image = tempImage;	              // is 1025*724 
    image.scaled(50,50,Qt::KeepAspectRatio);  
    item = new QGraphicsPixmapItem(QPixmap::fromImage(image));
    scene->addItem(item);

To copy to clipboard, switch view to plain text mode 

after scaling it still the image size is same as old temp image size only.

Check the signature of QPixmap::scaled
Its a const method i.e. it will not change the object state. What you need is this :-
.
.
image = image.scaled(50,50,Qt::KeepAspectRatio);
.
