To see how those features you need are called, look in ShapeEditPart:

if (NotationPackage.eINSTANCE.getSize_Width().equals(feature)
|| NotationPackage.eINSTANCE.getSize_Height().equals(feature)
|| NotationPackage.eINSTANCE.getLocation_X().equals(feature)
|| NotationPackage.eINSTANCE.getLocation_Y().equals(feature)) {
refreshBounds();
}
else if (NotationPackage.eINSTANCE.getFillStyle_FillColor().equals(f eature)) {
Integer c = (Integer) notification.getNewValue();
setBackgroundColor(DiagramColorRegistry.getInstance().getCol or(c));
}
else if (NotationPackage.eINSTANCE.getLineStyle_LineColor().equals(f eature)) {
Integer c = (Integer) notification.getNewValue();
setForegroundColor(DiagramColorRegistry.getInstance().getCol or(c));
}
else if (NotationPackage.eINSTANCE.getFontStyle().isInstance(notific ation.getNotifier()))
refreshFont();
And finally, here's a snippet:
SetBoundsCommand comm = new SetBoundsCommand(
getEditingDomain(), "Relocate X position",
new EObjectAdapter(view), bounds.getTopLeft());
try {
OperationHistoryFactory.getOperationHistory()
.execute(comm, new NullProgressMonitor(),
null);
} catch (ExecutionException e) {
// nada
}
You need to use SetRequest and SetValueCommand, instead.

Here is one of the ways to do it
First you create a change property request like this
ChangePropertyValueRequest req = new ChangePropertyValueRequest(
StringStatics.BLANK,Properties.ID_LINECOLOR,
FigureUtilities.colorToInteger(DiagramColorConstants.red));
you will notice that I'm passing the line color as the property ID, and
Red as the value
Now, we can call get command on the edit part, passing it the request
we just created
final Command cmd = editPart.getCommand(req);
Then execute the returned command (should check for null before trying
to execute) like this :
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;
}
};
try {
operation.execute(new NullProgressMonitor(), null);
} catch (ExecutionException e) {
// nothing to do here
}
this should change the line color to red

Hi Vlad! Thank you so much ^^
here is my code:
public void run(IAction action) {
SetRequest request = new SetRequest(
selectedElement.getEditingDomain(),
(EObject)selectedElement.getModel(),
NotationPackage.eINSTANCE.getLineStyle_LineColor(),
DiagramColorRegistry.getInstance().getColor(new RGB(200,20,0)));
SetValueCommand c = new SetValueCommand(request);
try {
OperationHistoryFactory.getOperationHistory()
.execute(c, new NullProgressMonitor(),
null);
} catch (ExecutionException e) {
// nada
}
I tried this, but im doing something wrong, because it doesnt work. =(
Besides, there are any way to execute an action (maybe an IAction, not
an IObjectActionDelegate, like this one) and call this "color changing"
by there?
Because when i call this action (by right-click, im using an extension
for popup menu on the diagram) the popup menu just shows up once! 0o
after the action is called, the popup dont come up again..
so is much better if i can execute this by a simple menu.
Thank you so much for your(both) help.
and sorry about my bad english, im brazilian. =D

To get to the diagram do smth like this:
View parentView = (View) someEditPart.getModel();
Diagram diagram = (Diagram) EMFCoreUtil.getContainer(parentView,
NotationPackage.eINSTANCE.getDiagram());
