Printable View
I want to make some fun tools for my children.
Does anybody know of an extension of QGraphicsView that allows user to resize scene items (such as QGraphicsPixmapItem).... or is there an easy way to code it?
A related question, has anybody tried to created a QGraphicsView where user can insert objects (shapes, lines, images) and then manipulate them (powerpoint-style)?
Finally, any fun Qt widgets for children? I'd like to organize a collection.
you can scale the item using item->scale() or resize the item by changing its boudingRect, and painting the new image with the new size inside the item. If you are working with a QPixmaps you can derive from QGraphicsItem, keep a copy of the pixmap and resize it for display using different geometries by using QPixmap::scaled().Quote:
