Hello!
I have an rcp application, with gmf model.
So i have somes edit part who contains a model and a figure.

I want update bounds or routing points of a figure, programmatically with using directly the edit part (or the figure).
Directly make a figure.setPoints(pointList); not works (because not persisted in file).

To update a model, i create command with a transactionnal editing domain.

But for update figures, what is the procedure?

Thanks!

Hi,

to make figures react on changes in your ecore model instanze you can do two things. You can use pins in graphical and gmfmap model which will have an OCL expression that is executed to determine whether the pin is executed. The second way is to override handleNotification in your editpart. If you want to persist your changes you should to these in the notation model. You can get the notation model element of a edit part by calling getNotationView on it. http://publib.boulder.ibm.com/infocenter/rsahelp/v7r0m0/topic/org.eclipse.gmf.doc/reference/api/runtime/org/eclipse/gmf/runtime/diagram/ui/editparts/IGraphicalEditPart.html#getNotationView()
