ShapeNode

A ShapeNode is an instance of the ShapeNode. This class is accessed through the GraphMLNode or the GraphMLGroupNode and allows to set various properties for the node Shape:

• Border style
• Label
• Background color
• Node geometry
• Node type (rectangle, circle, etc...)
• Node drop shadow

Some of these properties can directly be set or get through the node.

Getting the ShapeNode for a node

For a GraphMLNode, you can use the GraphMLNode.getShapeNode() method.

For a GraphMLGroupNode, there is one ShapeNode for each state (opened or closed). You can access the ShapeNode through one of the following methods:

• The GraphMLGroupNode.getClosedStateNode() method return the ShapeNode associated with the closed state
• The GraphMLGroupNode.getOpenedStateNode() method return the ShapeNode associated with the opened state

Setting the ShapeNode properties

To set the size of a node, such that it will always be set to correctly enclose its label:

      GraphMLNode node = diagram.addNode();
      ShapeNode shapeNode = node.getShapeNode();
      shapeNode.setAutosized(true);

To set the color of a node:

      GraphMLNode node = diagram.addNode();
      ShapeNode shapeNode = node.getShapeNode();
      shapeNode.setFillColor("red");

To add a drop shadow to a node with a default black color and an offset of 3 on x and y:

      GraphMLNode node = diagram.addNode();
      ShapeNode shapeNode = node.getShapeNode();
      DropShadow dropShadow = new DropShadow(3, 3);
      shapeNode.setDropShadow(dropShadow);

Can also be directly set through the node:

      GraphMLNode node = diagram.addNode();
      DropShadow dropShadow = new DropShadow(3, 3);
      node.setDropShadow(dropShadow);
