The
Composite
renderer provides support for symbols and composite graphics to
represent nodes and links. In particular, it allows you to:
- Perform Swing actions on predefined gestures defined for any child of a composite graphic.
- Define which child the links connect to.
The following code extract illustrates how to enable the
Composite
renderer:
SDM {
Composite: "true";
}
The following table lists the per-object properties of the
Composite
renderer.

-1
|
Specifies the index used with the indexed property
children
of composite graphics. The links connect to the nearest edge of
the bounding box of the child at the position defined by this
property. This property is defined on the objects of type node.

FromCompositePin
|
String
|
null
|
Specifies the name of a decoration in a
composite graphic, which is used to connect the origin of a
link. This property is defined on the objects of type link.
|
|
FromCompositePinPosition
|
String
|
Center
|
Connects the origin to this position of
the decoration. This property is defined on the objects of type
link.
|
|
ToCompositePin
|
String
|
null
|
Specifies the name of a decoration in a
composite graphic, which is used to connect the destination of
a link. This property is defined on the objects of type link.

Center
|
Connects the destination to this
position of the decoration. This property is defined on the
objects of type link.

The following code extract illustrates how
to configure the link connection rectangle:
node {
LinkConnectionRectangle: 0;
}
The following code extract illustrates how
to specify the decoration to be used to connect links:
link {
FromCompositePin:"decoration"; // use the name defined above
FromCompositePinPosition:"Center";
ToCompositePin:"decoration"; // use the name defined above
ToCompositePinPosition:"Center";
}
