I know how to add an element programmatically to an editor if it is opened,

can add a notation view to a file directly?
First try, if the editor is not open, I open it first, add element to it,
and then close it. It works, but it will flash the procedure of opening and
closing editor, which makes the user quite uncomfortable.
Is there any better solution? thank you.
I use the code below to add a notation view in an editor which is opened:
CreateViewRequest.ViewDescriptor viewDescriptor = new
CreateViewRequest.ViewDescriptor(
objAdapter, Node.class,
null,ProcessDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
CreateViewRequest cvRequest = new CreateViewRequest((viewDescriptor));
Command cmd =
targetDiagramEditor.getDiagramEditPart().getCommand(cvReques t);
IDiagramEditDomain dEditingDomain =
targetDiagramEditor.getDiagramEditPart().getDiagramEditDomai n();
dEditingDomain.getDiagramCommandStack().execute(cmd);

You can always use EMF API's to add and delete to the Resource, but this
means you have to create the view your self, for example use the
NotationFactory to create the generic View, Node or Diagram then you set
the attributes on it and add it to the resource using EMF API's
Or the other way is to visualize your diagram off screen without opening
an editor (check the CopyToImageUtil), then use the edit parts you had
in memory to get the commands.

Thank you for your quick answer:)

a few classes listed below perform complex initialization of graphical
viewer
with sole purpose to obtain DiagramEditPart:
PrintHelper.createDiagramEditPart(Diagram,PreferencesHint)
CopyToImageUtil.createDiagramEditPart(Diagram,Shell,Preferen cesHint)
OffscreenEditPartFactory.createDiagramEditPart(Diagram)
How can I get the Diagram from file, use EMF API's ? which api should i
use.
looking forward to your answers:)

I do it in the second method you suggest me:
I get the Diagram from digramfile, and then I use copyToImageUtil to create
a diagramEditPart based on the diagram. List codes below:
final Display display = Display.getDefault();
final Shell shell = new Shell();
shell.setSize(600,800);
shell.setText("testcopytoutil");
IPath resourcePath = diagramFile.getFullPath();
ResourceSet resourceSet = myEditingDomain.getResourceSet();
try {
Resource modelResource = resourceSet.getResource(
URI.createPlatformResourceURI(resourcePath
.toString()), true);
if(modelResource instanceof XMIResourceImpl){
Object[] objs = getElements(modelResource);
CopyToImageUtil copyToImageUtil = new CopyToImageUtil();
diagramEditPart = copyToImageUtil.createDiagramEditPart((Diagram)
objs[0],new Shell(),ProcessDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT) ;
}
} catch (WrappedException e) {
ProcessDiagramEditorPlugin
.getInstance()
.logError(
"Unable to load resource: " + resourcePath.toString(), e);
//$NON-NLS-1$
}
shell.layout();
shell.open();
while(!shell.isDisposed()){
if(!display.readAndDispatch())
display.sleep();
The code works well without reporting error, but I can not see anything from
the shell shows up....So I suspect if I did right?
By the way, I use the diagramEditPart which is returned by
copyToImageUtil.createDiagramEditPart method to get the commands to create
view on it, and I use resource.save(Collections.EMPTY_MAP) to save, but
after reopen the diagram file, I found nothing changed.
so I suspect second way is right?
Then I would try frist way. Would you please give me more detail suggests?
Which method should I use to add View created by NotationFactory to
resource? thank you
Best regards,

oh,yes! I did it by create view use CopytoImageUtil and add ito to the
resource using EMF API's.
