This sample demonstrates labeled ports on nodes. These ports are set up as panels, created within
|
|
the <b>makePort</b> function. This function sets various properties of the <a>Shape</a> and
|
|
<a>TextBlock</a> that make up the panel, and properties of the panel itself. Most notable are
|
|
<a>GraphObject.portId</a> to declare the shape as a port, and <a>GraphObject.fromLinkable</a> and
|
|
<a>GraphObject.toLinkable</a> to set the way the ports can be linked.
|
|
</p>
|
|
<p>
|
|
The diagram also uses the <b>makeTemplate</b> function to create the node templates with shared features.
|
|
This function takes a type, an image, a background color, and arrays of ports to create the node
|
|
to be added to the <a>Diagram.nodeTemplateMap</a>.
