Hi,

How do I programmatically trigger layout of a diagram similar to Diagram -> Arrange -> All?

Regards
Patrik

Try this where the parameter is the DiagramEditPart. It works for me

protected void arrangeRecursively(EditPart editpart) {
//ArrangeRequest request = new ArrangeRequest(ActionIds.ACTION_ARRANGE_ALL, LayoutType.DEFAULT);
ArrangeRequest request = new ArrangeRequest(RequestConstants.REQ_ARRANGE_DEFERRED);
List<EditPart> listToArrange = new ArrayList<EditPart>();
listToArrange.addAll(editpart.getChildren());

if(!listToArrange.isEmpty()) {
for(Object element : editpart.getChildren()) {
if(element instanceof EditPart) {
arrangeRecursively((EditPart)element);
}
}

request.setViewAdaptersToArrange(listToArrange);

Command command = editpart.getCommand(request);
command.execute();
}
}
