Interface AccessibleAnchorProvider
-
All Known Implementing Classes:
-
AbstractConnectionEditPart.DefaultAccessibleAnchorProvider,
AbstractGraphicalEditPart.DefaultAccessibleAnchorProvider
- public interface AccessibleAnchorProvider
This class provides keyboard accessibility support for Anchors. Anchors are
simply locations (relative to the Viewer's Control) on the GraphicalEditPart's figure
indicated by
Points. Anchors are used when
creating or manipulating connections graphically. Accessible Anchors are the
locations that should be used during keyboard connection manipulation.
Keyboard connection manipulation moves the Mouse cursor programmatically to the
AccessibleAnchor's location. Targeting is still performed as if the User were using
the Mouse and not the keyboard. Therefore, the GraphicalEditPart should provide
locations that will result in its being targeted by the current tool.
Connection operations involves either the source or target end of a connection. The
AccessibleAnchorProvider has the option of returning different locations
depending on the context of the operatation.

getSourceAnchorLocations
public java.util.List getSourceAnchorLocations()
- Returns a list of Points in absolute coordinates where source anchors are
located. Tools that work with connections should use these locations when operating in
accesible keyboard modes.
