Hi,

I am trying to create an graphical editor with a simple model, a single class stores the type of figure to be displayed. In the createFigure() I return a figure depending on the type in the model. When I open a file with the editoe though, nothing is displayed, there are no error messages logged either.

public class ContentModel {

List _shapes = new ArrayList();

public List getShapes() {
return _shapes;
}

public void setShapes(List shapes) {
_shapes = shapes;
}

public class ShapeModel implements Serializable{

private static final long serialVersionUID = -7303239549506441257L;
private String _type;

public String getType() {
return _type;
}

public void setType(String type) {
_type = type;
}

}

public class ShapesEditPart extends AbstractGraphicalEditPart implements
NodeEditPart {

String RECT_TYPE = "RECTANGLE";
String CIRC_TYPE = "CIRCLE";

/* (non-Javadoc)
* @see org.eclipse.gef.editparts.AbstractGraphicalEditPart#createFi gure()
*/
@Override
protected IFigure createFigure() {
ShapeModel model = (ShapeModel)getModel();
IFigure figure;

if(RECT_TYPE.equals(model.getType())){
figure = new RectangleFigure();
} else {
figure = new Ellipse();
}
figure.setOpaque(true);
return figure;
}
...
}

Thanks in advance for your help

Do you have a factory in place to create the EditPart from your model and is it registered with your Editor?

yes, I do have a factory for creating the editparts with the following methods

public EditPart createEditPart(EditPart arg0, Object arg1) {

System.out.println("createEditPartinvoked...");

EditPart editPart = getEditPart(arg1);

editPart.setModel(arg1);
return editPart;
}

private EditPart getEditPart(Object model) {
if(model instanceof ContentModel){
return new ContentsEditPart();
}
return new ShapesEditPart();
}

This factory is also registered in the Editor using

@Override
protected void configureGraphicalViewer() {
super.configureGraphicalViewer();
getGraphicalViewer().setEditPartFactory(new SandboxEditPartFactory());
getGraphicalViewer().setRootEditPart(new FreeformGraphicalRootEditPart());
}

where do you set the model to the graphicalViewer? Could you please post
the entire code?

I think you need to just set some size for it

figure.setPreferredSize(100,100);
also set the some background color

hope it will work
