Need to help to select the QGraphicsPixmapItem when click on it.

Himanshu Rohilla

Thanks in advance ...... :)

it should be enough to call this on your QGraphicsPixmapItem:
@item->setFlag(QGraphicsItem::ItemIsSelectable);@

But, I also want to draw rectangle around the image when i click on or select it ...

I am attaching the URL of images of my desire result.

The following link is just my normal image on view.

The following link will show my desirable result.

then also implement the paint method:
@
void MyGraphicsPixmapItem::paint(QPainter painter, const QStyleOptionGraphicsItem option, QWidget *widget)
{
Q_UNUSED(widget);

painter->setRenderHint(QPainter::SmoothPixmapTransform, (d->transformationMode == Qt::SmoothTransformation));

painter->drawPixmap(this->offset(), this->pixmap());

if (option->state & QStyle::State_Selected)
{
    //draw your selection frame
}

}
@

But since it seems that you also want interaction with the graphicsitem it would be better to introduce a subclassed QGraphicsItemGroup and do your painting and interaction there. Because you would also have to update the bounding rect of the pixmap item once it is selected, etc. ...

Ok....

Can i do same task for QGraphicsPathItem or whatever i draw on View using this method ?

as long as you stay generic to QGraphicsItem ... why not.

Himanshu Rohilla

paint method is not calling ..... :(

Himanshu Rohilla

But when i click on or select the image, it does not show its Selected State(i.e. QStyle::State_Selected) .
