Rendering decorators for connections [message #560232]

In the Tutorial example, a warning decorator for the ECLass pictogram was added if the class name started with a lower case letter.

Is rendering decorator supported for connections? My use case is I want to model process flows using connections. Process flow names are displayed with connection text decorators. If a process flow is invalid, I'd like to display a warning icon in front of the process name which is modeled using connection text decorator.

Does Graphiti support this type of rendering decorators? I tried to follow the Tutorial example to add an image rendering decorator to the connection text decorator but could not get it to work. If Graphiti support this type of rendering decorator, could you give me some code snippet in the context of the Tutorial example?

Thanks!

There was a small bug in the framework. I have fixed it today.

Now you can provide an image decorator for your ConnectionDecorator via the ToolBehaviorProvider. You can do it in the same way, as we did it in our tutorial for the ECLass.

One remark: Currently you must place your image decorator in the visible area - that means inside the text decorator. You can set the location with:

ImageDecorator imageRenderingDecorator = new ImageDecorator(IPlatformImageConstants.IMG_ECLIPSE_ERROR_TSK );
imageRenderingDecorator.setX(0);
imageRenderingDecorator.setY(0);

We will work on a solution to place it in front of the text decorator. But this needs some time.

Matthias

Sorry, currently there is no progress on this topic. We had a lot of other important things to do.

It would be very helpful if you open a bugzilla bug to track this issue.

Hopefully we can address this problem in one of our next development takts.

Regards,
Matthias
