How do I add an icon to a node? [message #870091]

Hi,

I have created a diagram in which I have multiple rectangular nodes with
labels in the center of each node. Now I would like to add an icon to
the node (not the label) in the corner of the node to distinguish the
node types. Currently I'm using colors to distinguish the nodes but this
fails in black and white prints.

Is there somewhere in the gmfgraph I need to add something to the
rectangles or is there a code extension I need to make in the node EditPart?

I'd appreciate any advice or examples.

Best regards,

Nigel

Hi Nigel,
you can add icons to a node via the org.eclipse.gmf.runtime.diagram.ui.decoratorProviders extension point.
Take a look at class BookmarkDecorator to get an idea how to implement your own decorator. Don't forget to set isVolatile to false when calling getDecoratorTarget().addShapeDecoration(..). the icon won't be printable otherwise.
Regards,
Andreas
