* @brief The AbstractPartEllipse class
|
|
* This is the base class for all ellipse based item like ellipse, circle, arc.
|
|
* This class only provide common method for edit the ellipse like rect that contain the ellipse.
|
|
* All coordinates is in item coordinate, except pos(), center(), centerX() and centerY()
|
|
* which are in parent coordinate (or scene if no parent).
|
|
*
|
|
* In several points, this class is a copy of QGraphicsEllipseItem with some change,
|
|
* (the use of Q_PROPERTY) to be easily used with Element editor.
