Hi All,
I'm trying to change the colors of nodes programmatically. I've followed
this description but haven't gotten it to work:
http://www.sagewire.org/gmf-modeling-eclipse/changing-connec tion-color-programtically-352798.aspx
I've put in some flags and the code is being executed but the color isn't
changing.
I'm calling the EditPolicy with an OpenRole (double click), does it matter
how the EditPolicy is called or am I missing something really obvious?
Thanks,
Gaff
public class ColorEditPolicy extends OpenEditPolicy {
@Override
protected Command getOpenCommand(Request request) {
EditPart targetEditPart = getTargetEditPart(request);
if (targetEditPart instanceof IGraphicalEditPart == false)
return null;
IGraphicalEditPart editPart = (IGraphicalEditPart) targetEditPart;
EObject modelElement = editPart.resolveSemanticElement();
System.out.println("Flag1");
Command ret = null;
ChangePropertyValueRequest req = new ChangePropertyValueRequest(
StringStatics.BLANK, Properties.ID_LINECOLOR,
FigureUtilities.colorToInteger(DiagramColorConstants.red));
System.out.println("Flag2");
final Command cmd = editPart.getCommand(req);
System.out.println("Flag3");
AbstractEMFOperation operation = new
AbstractEMFOperation(((IGraphicalEditPart) editPart).getEditingDomain(),
StringStatics.BLANK, null) {
protected IStatus doExecute(IProgressMonitor monitor, IAdaptable
info)throws ExecutionException {
cmd.execute();
return Status.OK_STATUS;
}
};
System.out.println("Flag4");
try {
operation.execute(new NullProgressMonitor(), null);
} catch (ExecutionException e) {
// nothing to do here
}
return ret;
}

Not sure what you're trying to do with the code below but this code works:
public class ColorEditPolicy extends OpenEditPolicy {
protected Command getOpenCommand(Request request) {
if (getHost() instanceof IGraphicalEditPart) {
ChangePropertyValueRequest req = new
ChangePropertyValueRequest(StringStatics.BLANK,
Properties.ID_LINECOLOR,
FigureUtilities.colorToInteger(DiagramColorConstants.red));
return getHost().getCommand(req);}
return null;
}
}
