Hi there,
I need to modify background color and location's node programmatically.

To do this I found on this forum some helps. But I don't have any "ComponentImpl" and I don't know where I can find it.

Finally, I use ShapeNodeEditPart#getNodeFigure().setLocation(Point p) and setBackgroundColor(Color bg) like this :

	protected void handleNotificationEvent(Notification notification) {
		super.handleNotificationEvent(notification);

		Point rect = new Point (100,100);
		System.out.println ("change background and location");
		this.getNodeFigure().setLocation(rect);

		Color bgColor = new Color (null, 255,0,0);
		bgColor.dispose();
		this.getNodeFigure().setBackgroundColor(bgColor);
		refreshBackgroundColor();
		
		refreshChildren();
		if (AmDiagramEditorUtil.dEditPart != null)
			AmDiagramEditorUtil.dEditPart.refresh();
	}

The handle function is executed, however, nothing happens.

Does anyone have an idea about this ?

Regards,

Hi,

did you try this

performRequest(new Request(RequestConstants.REQ_REFRESH));

You should consider using the GMF notation model to change the visual appearance. You can get the notation model element of you editpart by using

getNotationView()

You can also try the SetBoundsCommand for setting the location. I used it to set the size.

Rectangle rect = figure.getClientArea().getCopy();
rect.setSize((cachedSize != null) ? cachedSize : new Dimension(10, 10));
SetBoundsCommand sbc = new SetBoundsCommand( this.getEditingDomain(), "change size", new EObjectAdapter((View) this.getModel()), rect);
getEditDomain().getCommandStack().execute(new ICommandProxy(sbc));

Hope that helps.

Ralph

Thanks for your reply.
the performRequest changes nothing but your two others solutions work both.

Thank you !

Hi, I need you help urgently. I have the same problem. But I can't solve it after seeing the reply. Could you tell me how to achieve it in DETAIL? Because I can't find the function or class you mentioned in the question and I don't know where I should put the code! Thank you very much.

Best Regards,
Vincent
