@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.
