Orthogonal Edge Editing Demo

This demo shows the customization of orthogonal edge editing.

Using the GraphDecorator, the edge is decorated with custom implementations of the IOrthogonalEdgeHelper interface.

Things to Try

Drag segments and bends of the edges and observe the different characteristics.

Red edge: Orthogonal edge editing is disabled. The segments are straight lines with arbitrary slope. Dragging an unselected segment creates a new bend.
Green edge: Orthogonal edge editing is enabled. While dragging, all segments stay orthogonal and new bends are created as needed.
Purple edge: Same behavior as the green edge. In addition, the locations of the source port and target port are constraint to the given port candidates of the nodes.
Orange edge: Same behavior as the green edge. In addition, the source port and the target port can be placed at any location inside the node since they use dynamic port candidates.
Yellow edge: Same behavior as the green edge. In addition, dragging the first (or last) segment of the edge will create only one new bend instead of two.
Blue edge: Orthogonal edge editing is enabled for the inner segments but the first and the last segment can have an arbitrary slope. If a new bend is added to one of these two segments, the newly created inner segment becomes orthogonal immediately.
