A Specialization of
EditPart
for use with GraphicalViewers
. The visual part of a GraphicalEditPart is a
Figure
.
IMPORTANT: This interface is not intended to be implemented by clients.
Clients should inherit from
AbstractGraphicalEditPart
. New methods may
be added in the future.

Method Details
-
addNodeListener
Adds a NodeListener to the EditPart. Duplicate calls result in duplicate notification.- Parameters:
listener
- the Listener
-
getFigure
IFigure getFigure()Returns the primary Figure representing this GraphicalEditPart. The parent will add this Figure to its content pane. The Figure may be a composition of several Figures.- Returns:
- this EditPart's Figure
-
getSourceConnections
List<? extends ConnectionEditPart> getSourceConnections()Returns the source connections for this GraphicalEditPart. This method should only be called by the EditPart itself, and its helpers such as EditPolicies.- Returns:
- the source connections
-
getTargetConnections
List<? extends ConnectionEditPart> getTargetConnections()Returns the target connections for this GraphicalEditPart. This method should only be called by the EditPart itself, and its helpers such as EditPolicies.- Returns:
- the target connections
-
getChildren
List<? extends GraphicalEditPart> getChildren()The children of GraphicalEditparts have to be GraphicalEditParts. Therefore the GraphicalEditPart refines this method from its parent interface.- Specified by:
getChildren
in interfaceEditPart
- Returns:
- a
List
of children - See Also:
-
getContentPane
IFigure getContentPane()The Figure into which childrens' Figures will be added. May return the same Figure asgetFigure()
. The GraphicalEditPart'sprimary Figure
may be composed of multiple figures. This is the figure in that composition that will contain children's figures.- Returns:
- the content pane Figure
-
removeNodeListener
Removes the first occurance of the specified listener from the list of listeners. Does nothing if the listener was not present.- Parameters:
listener
- the listener being removed
-
setLayoutConstraint
Sets the specified constraint for a child's Figure on thecontent pane
figure for this GraphicalEditPart. The constraint will be applied to the content pane'sLayoutManager
.revalidate()
is called on the content pane, which will cause it to layout during the next update.- Parameters:
child
- the child GraphicalEditPart whose constraint is being setfigure
- the Figure whose constraint is being setconstraint
- the constraint for the draw2dLayoutManager
