Hi all,

I want to perform some gmf requests (eg: Arrange all) programatically. I would need the Editparts (for the container Elements) of my Diagram. Is it possible to retrieve them from my

org.eclipse.sirius.diagram.DDiagram

and how do I accomplish that?
Respectively whats the proper way to access the Editparts of my Sirius Diagram?

I tried the following, but I'm kinda lost now:

DDiagramEditPart dDiagramEditPart = null;
	IEditorPart editor = EclipseUIUtil.getActiveEditor();
	if (editor instanceof DiagramEditor) {
	    DiagramEditor diagramEditor = (DiagramEditor) editor;
	    DiagramEditPart diagramEditPart = diagramEditor.getDiagramEditPart();
	    if (diagramEditPart instanceof DDiagramEditPart) {
		dDiagramEditPart = (DDiagramEditPart) diagramEditPart;
	    }
	}

Thank you,

Regards,
Matt

Hi.

For information, if you have Sirius-specific questions the should be
posted in the Sirius forum: https://www.eclipse.org/forums/index.php/f/262/.

It would be possible, but more cumbersome to navigate "backwards" from
the DDiagram to GMF's Diagram to the DiagramEditPart.

From this DiagramEditPart, you can look at
org.eclipse.sirius.diagram.ui.tools.internal.layout.LayoutUtil.arrange(DiagramEditPart)
to launch the "Arrange All" action. It's technically internal, but only
a few lines of simple code, so you can reproduce it in your code without
worry.
