#include <QtView.h>
Inheritance diagram for QtView:
It is derived from QCanvasRectangle in order to get a position and size on the canvas. The view thus becomes a QCanvasItem. The inherited active state is used to lock the size and position on the canvas. The inherited selected state is used to highlight the selected item. It also derives from QtViewImp which contains most of the drawing code.
