[news.eclipse.modeling.gmf] [solved] Re: Set backgound color depending o

[Marc Moser <moser@xxxxxxxxxxxx>]

Hi,

A short description how I solved the problem, in case anyone is interested.

In the generated class *.diagram.edit.parts.ClassAEditPart, I've 
overridden method refreshBackgroundColor() something like this:

	protected void refreshBackgroundColor() {
		Color backgroundColor = THIS_BACK; // THIS_BACK is created by setting 
background color in figure
		View notationView = getNotationView();
		EObject element = notationView.getElement();
		if (element instanceof ClassA) {
			ClassA a = (ClassA) element;
			backgroundColor = a.getColor();
		}

		setBackgroundColor(backgroundColor);
	}

Best,
Marc
