Detailed Description
A convenience class that encapsulates geometry management, handles mouse and hover events, embeds and aligns symbols and finally draws the lines and points.
Context menu events are handled in AssociationWidget.
This class is infact a draw and event handling proxy for AssociationWidget.
- Note
- m_activePointIndex and m_activeSegmentIndex can't be active at same time!
