How to change the color of elements programmatically [message #692388]

Hi,

How could I change the color of diagram elements programmatically in Papyrus 0.8.0?

I can get the color of ShapeImpl of the elements with a code like si.getFillColor() but setting the color with si.setFillColor(10000000) throws an exception:
java.lang.IllegalStateException: Cannot modify resource set without a write transaction

How should I do the write transaction?

Not tested, but probably something like:

TransactionalEditingDomain ted = TransactionUtil.getEditingDomain(shape);
ted.getCommandStack().execute(new RecordingCommand(ted) {
protected void doExecute() {
shape.setFillColor(myColor);
}
});

Thanks a lot! That seems to do the trick.

Hi Neslepaks,

a general question on this:

Did you access the DI file or the notations file to reset the color of an
element on the canvas?

Could you maybe post a snippet how to start with this? Actually, it sounds
very interesting, actually, I do not have a starting point for this
activity.

Thanks a lot

I didn't access any files.

This is the way I changed the color:


ServicesRegistry serviceRegistry;
ISashWindowsContainer container;

serviceRegistry = ServiceUtilsForActionHandlers.getInstance().getServiceRegistry();
container = ServiceUtils.getInstance().getISashWindowsContainer(serviceRegistry);

IEditorPart activeEditor = container.getActiveEditor();
EList el = ((UmlGmfDiagramEditor) activeEditor).getDiagram().getChildren();

Iterator<ShapeImpl> iter = el.iterator();
while (iter.hasNext())
{
    ShapeImpl si = iter.next();
    final org.eclipse.gmf.runtime.notation.Shape shape = 
	  (org.eclipse.gmf.runtime.notation.Shape) si;

    final int myColor = 10265827; //red
    TransactionalEditingDomain ted = TransactionUtil.getEditingDomain(shape);
    ted.getCommandStack().execute(new RecordingCommand(ted) {
        protected void doExecute() {
            shape.setFillColor(myColor);
    }
    });
}

Hey Neslepleaks,

thanks for your hint. I tried it and it worked almost as desired, BUT: how
did you manage to updat the shape within on the canvas immediately. In my
case, the shape is update after I perform a subsequent change that causes
the canvas to refresh. I'm missing something like Diagram.refresh().

Could you point me to somewhere?

Yes, the color update happens immediately and, as far as I know, we don't use any kind of refresh or update call for canvas separately.

Hi,

is there a way to resize the figure, too?

Back in the past there were nice functions in com.cea.papyrus.diagraminterchange2.di2.GraphNode but they seem to have disappeared.

GraphNode di2Component = Di2Factory.eINSTANCE.createGraphNode();
			di2Component.setPosition(new Point(100, 100));
			di2Component.setSize(new Dimension(500, 300));			
			di2Component.setIsVisible(true);
			di2Component.setLineStyle("solid");
...

thanks
