Public Member Functions | |
GraphicsPointEllipse (GraphicsPoint &graphicsPoint, const QRect &rect) | |
Single constructor. | |
QVariant | itemChange (GraphicsItemChange change, const QVariant &value) |
Intercept moves by dragging so moved items can be identified. This replaces unreliable hit tests. | |
virtual void | hoverEnterEvent (QGraphicsSceneHoverEvent *event) |
Accept hover so point can be highlighted when cursor is over it as a guide to user. | |
virtual void | hoverLeaveEvent (QGraphicsSceneHoverEvent *event) |
Unhighlight this point. | |
void | setRadius (int radius) |
Update the radius. | |
void | setShadow (GraphicsPointEllipse *shadow) |
Bind this graphics item to its shadow. | |
