Connect Shapes

Connect Shapes

This section explains how to connect two shapes using Aspose.Diagram for Java.

Connect Shapes

The connectShapesViaConnector method connect two shapes via a connector in the Page class.

The code below shows how to:

1. Create a diagram from stencil.
2. Add two rectangles shape to page.
3. Add a connector shape to page.
4. Connect the two rectangles with the connector using connectShapesViaConnector mothod
5. save diagram

Connect Shapes Programming Sample

Use the following code to connect shapes using Aspose.Diagram for Java.

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(ConnectShapes.class);
String stencil = dataDir + "Basic Shapes.vss";

// create a diagram from stencil
Diagram diagram = new Diagram(stencil);
String connectorMaster = "Dynamic connector";
String rectangleMaster = "Rectangle";
// add two rectangles to page 0
long rectangle1 = diagram.addShape(2, 2, rectangleMaster, 0);
long rectangle2 = diagram.addShape(2, 4, rectangleMaster, 0);
// add a connector to page 0
Shape connector1 = new Shape();
long connecter1Id = diagram.addShape(connector1, connectorMaster, 0);
// connect the two rectangles with the connector
diagram.getPages().get(0).connectShapesViaConnector(rectangle1, ConnectionPointPlace.RIGHT, rectangle2, ConnectionPointPlace.BOTTOM, connecter1Id);

// If the connection of shapes has name, we also could use connection name to connect like below
//diagram.getPages().get(0).connectShapesViaConnector(shape1, "Port7", shape2, "Port21", connecter1Id);
// The code line above is equal to the below two lines
//diagram.getPages().get(0).glueShapeToConnectorBeginX(shape1, "Port7", connecter1Id);
//diagram.getPages().get(0).glueShapeToConnectorEndX(shape2, "Port21", connecter1Id);

// Save diagram
diagram.save(dataDir + "ConnectShapes_out.vsdx", SaveFileFormat.VSDX);
