STP/BPMN Component/STP BPMN Presentation (Part 1)
- Quick access
My first BPMN process
- Creating the diagram
Let's create our first Hello World process. Let's create a simple project:
And give it an appropriate name.
You can create a new BPMN diagram by selecting the Examples category in the creation wizard.
The wizard is very straight-forward, all you need is to indicate a folder and a file name.
After clicking on Finish, you will see two new files appearing in the project.
You can double-click on the bpmn_diagram file to open it as an editor. The diagram initially contains one pool and a task.
- How to create shapes in the BPMN diagram editor
You can use the palette to drop elements on the diagram. The palette can either be shown as a different view, or attached to the diagram.
To drop a shape on the diagram, just click on it and then click on the diagram. If you want to drop the same shape several times, you can double-click on it and it will appear as locked.
To unlock it, just click on it again.
You can also use diagram assistants to create shapes. Leave your mouse where you want to drop the shape and you will see a bubble appear.
You can connect and create shapes using handles placed on the activities of the diagram.
Leave your mouse on the activity you want to connect. You will see the handles appear. Then click on the handle and drag it to another activity.
Here are the messaging edges handles: File:MessagingEdgeHandles.png and the sequence edge handles:
If you release the mouse button while not being over and activity, the menu below will appear to give you a chance to create the other extremity of the edge.
After using repeatedly the operations described above, you can create a HelloWorld process that looks like this:
That's all folks !
- Copy/Paste in a text editor
Usually, people create a diagram under one application, then exports it to an image, and paste it to a text processor in the end.
With GMF, you can copy your selection of shapes, and paste it directly to your preferred text processor.
- Linking documents to the diagram.
You can drop a file contained in the project of the diagram on one of the shapes. Just drag and drop the file from the resource navigator to the shape. You will see the icon representing a file on the shape.
Or you can directly press shift and simultaneously double-click on the shape.
- Change the type of the activity
