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

I'll reproduce my answer to the same question on the GMF forum:

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.
