This page features the tutorial Get the most of the BPMN modeler for EclipseCon 2008.

This page is related to Developing with the STP BPMN modeler and Using the STP BPMN modeler.

This is a work in progress, please watch the page to stay tuned. If you want to submit something to this page, please post to this mailing list first.

Here is the outline of the tutorial:

    • Gateways
  • Sequence and messaging edges
    • Connection rules
    • Customized handles
    • Customize the edge and the reset connection button
    • Change the order of edges for an activity
  • Insert space tool

    • Attaching a reference to a project file to a shape
    • Opening a file

The annotation coding sample

The bug view

This sample demonstrates how you can integrate the BPMN modeler with an external application. Our coding sample will consist in creating a new plugin, which will transform bugs into text annotations during a drag and drop operation.

In this sample we will use a plugin (org.eclipse.bpmn.sample.bugView) which shows a tree view of various bugs.

Creating the drag and drop plugin

Create the plugin, make it dependent of org.eclipse.stp.bpmn.diagram and org.eclipse.stp.bpmn.sample.bugView.

IDnDHandlers

Open the extensions tab and create a new extension for org.eclipse.core.runtime.adapters:

<extension point="org.eclipse.core.runtime.adapters">
   <factory adaptableType="org.eclipse.stp.bpmn.sample.bugView.bug.view.IBug" 
            class="org.eclipse.stp.bpmn.sample.bugDnD.dnd.BugAdapterFactory">
      <adapter type="org.eclipse.stp.bpmn.dnd.IDnDHandler"/>
   </factory>
</extension>

Then, we create the adapter factory by naming it BugAdapterFactory and placing it in dnd package under the plugin class.

The contents of the adapter factory should like this:

public class BugAdapterFactory implements IAdapterFactory {

    public Object getAdapter(Object adaptableObject, Class adapterType) {
        if (adaptableObject instanceof IBug && 
                IDnDHandler.class.equals(adapterType)) {
            return new BugDnDHandler((IBug) adaptableObject);
        }
        return null;
    }

    public Class[] getAdapterList() {
        return new Class[] {IDnDHandler.class};
    }

}

We create a BugDnDHandler class that will extend AbstractViewDnDHandler.

In its constructor this class takes a IBug object.
