Is it possible to do a drag and drop on an image to a rectangle?

I try to do a drag and drop on an image to a rectangle.

I have an image whose id: icon
@
Image {
id: icon
width: 64
height: 64
source: "liverbird.gif"

       MouseArea {
           id: liverbirdMouseArea
           anchors.fill: parent
           width: 64
           height: 64

           drag.target: parent
           drag.axis: Drag.XandYAxis
           onReleased: {
               cc.putItemIntoSlide(cubeFront, icon);
           }

       }
   }

@

and I try to put icon into a rectangle with id:cubeFront. So when I click icon, drag it to cubeFront, and release, I will go into the function putItemIntoSlide, which sets icon as a child of cubeFront.

I check if icon is in cubeFront, by mapping the coordinates of icon to cubeFront, and then check if cubeFront contain this coordinates.

@
void cc::putItemIntoSlide(QGraphicsObject * slide, QGraphicsObject * object)
{
if (object != NULL)
{
if (slide->contains((slide->mapFromItem(object,object->pos()).toPoint())))
{
qDebug("got object in slide");
object->setParentItem(slide);
}
}
else
{
qDebug("no object");
}
}

But this doesn't work. Any suggestions? Much appreciated. =)

I found the solution! This is an easy way to drag and drop in qt

@
QGraphicsItem *oldParent = object->parentItem();
if (slide->contains((slide->mapFromItem(oldParent,object->pos()))))
{
qDebug("got object in slide");
object->setParentItem(slide);
object->setPos(slide->mapFromItem(oldParent,object->pos()));
}
else
{
object->setParentItem(0);
}
