Hi, I am working on GMF aplication and I am quite new at GMF development. I am wondering if is there any possibility to set custom image as background of node/rectangle. I just need to draw a dashed line in the middle of rectangle, so I have tried to draw it programaticaly, but rectangle is also compartment node, so the drawing took place for child nodes. Since I have found out this, I am looking for way to set rectangle background image.
I wasnt able to find out any advice, but I think that there should be some way to achieve it. I would be very grateful for every advice.

Ondra

I have created class MyRectangle, which I should be a background of compartment rectangle. The code of MyRectangle is something like this:
public class MyRectangle extends RoundedRectangle {
	
	public MyRectangle()
	{
		super();
		this.setOutline(false);
		this.setSize(100, 100);
	}
	
	@Override
	public void paintFigure(Graphics graphics)
	{
		super.paintFigure(graphics);
		graphics.setForegroundColor(ColorConstants.black);
		graphics.setForegroundColor(ColorConstants.black);
		graphics.setLineStyle(Graphics.LINE_DASH);
		graphics.setLineWidth(3);
		Rectangle r = getBounds();
		
		graphics.drawLine(
				new Point(r.x + r.width / 2, r.y + r.height * 0),
				new Point(r.x + r.width / 2, r.y + r.height * 1));

	}
}

And then I put this into compartment figure:
	public IFigure createFigure() {
		ResizableCompartmentFigure result = (ResizableCompartmentFigure) super
				.createFigure();
		MyRectangle rect = new MyRectangle();

		result.add(rect);

But this is not the right way, since MyRectangle took a space inside the compartment. Is there any posibility to set this as background?

Hi,
what about overriding the paintFigure method of the ResizableCompartment?

ResizableCompartmentFigure figure = new ResizableCompartmentFigure(
				getCompartmentName(), getMapMode()) {
			@Override
			public void paint(Graphics graphics) {
				super.paintFigure(graphics);
				graphics.setForegroundColor(ColorConstants.black);
				graphics.setForegroundColor(ColorConstants.black);
				graphics.setLineStyle(Graphics.LINE_DASH);
				graphics.setLineWidth(3);
				Rectangle r = getBounds();

				graphics.drawLine(new Point(r.x + r.width / 2, r.y + r.height
						* 0), new Point(r.x + r.width / 2, r.y + r.height * 1));
			}
		};


Regards,
Andreas
