Alter the location and the background color of EditPar [message #1042666]

Hello,
I have an EditPart I need to alter its location and background color.
I have managed to alter its location using:

	ChangeBoundsRequest request = new ChangeBoundsRequest(RequestConstants.REQ_MOVE);
		request.setEditParts(editPart);
		request.setMoveDelta(newLocation);

		Command cmd = editPart.getCommand(request);
		if (cmd != null && cmd.canExecute()) {
			cmd.execute();
		}

I have managed to alter the background color by:

editPart.getContentPane().setBackgroundColor(color);

But whenever I close and re open the application,the color changes I made goes away!

How can I commit the background color !

Hi Fatla,

you can change the background color of the figure by using the default diagram actions, via the diagram-menu entries or the colorappearancepropertypage.
Either actions trigger commands to alter the settings within the editpart's notation model. This way, the information get's persisted and is present after diagram-reopening.
If you just change the color by setting the editparts resp. figure's background manually, this change will not be persisted.

Regards
Thomas

"Either actions trigger commands to alter the settings within the editpart's notation model."

Yes you are right about persistence.
I have manged to alter the location using the "ChangeBoundsRequest".

What kind of commands can I use to alter the color !
