I would like to use an image, like a bmp file, for my object figures in a
GEF
editor. To evaluate this I started with the LinklessNetworkEditor and
LinklessNetworkModel eamples. I modified the NodeFigure.java to extend
ImageFigure rather than Ellipse. When I run the editor and add a new node
I see the image of my bmp file, but I can not move it. When I select the
node and move it the image does not follow. It looks like the extent box
of the node is a view 'window' on the canvas. When I move it back to the
original location of the image I see it again.
Can anyone explain what is happening and help me pls. See a code fragment
below.
Thanks,
Mark.
...
public class NodeFigure
extends ImageFigure
{
protected EllipseAnchor incomingConnectionAnchor;
protected EllipseAnchor outgoingConnectionAnchor;
protected Label label;
protected XYLayout layout;
public NodeFigure(Image image) {
layout = new XYLayout();
setLayoutManager( layout );
setImage(image);
setBackgroundColor( ColorConstants.white );
setOpaque( false);
incomingConnectionAnchor = new EllipseAnchor(this);
outgoingConnectionAnchor = new EllipseAnchor(this);
label = new Label("");
add(label);
}

Hi Mark,
I haven't come across NodeFigure nor the examples you've mentioned.
Anyhow, if you just need to display an image in your diagram, you might try
using a Label, and use Label#setIcon to display the image you want. I
suppose you can load the Images as you're doing right now.
Works for me - though I don't know if you need anything specific to
NodeFigure.
Hope this helps,
All the best,
Brian.
