Hi there!
I was wondering if there is any way to access diagram data from a custom
action (implementing IAction)? I have GMF-generated editor for my domain
model. I would like to add simple action to it (to the menu bar) which
can edit opened diagram.
I've been looking for the solution almost all day. All I have is:
....
public class MyAction implements IAction {
public void run() {
IWorkbenchWindow workbenchWindow =
PlatformUI.getWorkbench().getActiveWorkbenchWindow();
IWorkbenchPage activePage = workbenchWindow.getActivePage();
IEditorPart activeEditor = activePage.getActiveEditor();
IEditorInput editorInput = activeEditor.getEditorInput();
....
Can anyone tell me if this is a right direction or a dead end?
I will appreciate any help.
Regards
Tommy

You have to cast your editorPart to a GEF GraphicalEditor.
From there you get the graphical viewer -> getContents() to get the
diagram edit part. If you call resolveSematicElement() on that edit part
you get the root model element of your diagram.
Note that you will have to use commands to manipulate the model. So
basically, wrap your normal EMF manipulations in an
AbstractTransactionalCommand. You can execute those with
OperationHistory.getOperationFactory().execute().
Here's an example (sorry it's verbose)
(1) plugin.xml
<extension point="org.eclipse.ui.popupMenus">
<objectContribution
adaptable="false"
id=" ca.uwaterloo.watform.bluenose2.diagram.ui.actions.Bluenose2A bstraction "
objectClass=" org.eclipse.gmf.runtime.diagram.ui.editparts.IGraphicalEditP art ">
<action
label="Create Abstract Block"
class=" ca.uwaterloo.watform.bluenose2.diagram.ui.actions.CreateAbst ractBlockAction "
menubarPath="additions"
enablesFor="*"
id="Bluenose2AbstractBlockAction">
</action>
</objectContribution>
</extension>
(2) action code:
public class CreateAbstractBlockAction implements IObjectActionDelegate {
private IWorkbenchPart myPart;
private IStructuredSelection mySelection;
private EObject parentBlock;
private List childrenBlock;
private IGraphicalEditPart someEditPart;
public void setActivePart(IAction action, IWorkbenchPart targetPart) {
myPart = targetPart;
}
public void selectionChanged(IAction action, ISelection selection) {
mySelection = StructuredSelection.EMPTY;
action.setEnabled(false);
if (selection instanceof IStructuredSelection == false
|| selection.isEmpty()) {
return;
}
if (myPart instanceof Bluenose2DiagramEditor == false)
return;
mySelection = (IStructuredSelection) selection;
someEditPart = (IGraphicalEditPart) mySelection.getFirstElement();
//postpone complicated checks till later when it's run
action.setEnabled(true);
}
public void run(IAction action) {
ProgressMonitorDialog progressDialog = new ProgressMonitorDialog(myPart.getSite().getShell());
IRunnableWithProgress runnable = new IRunnableWithProgress() {
public void run(IProgressMonitor monitor) throws InvocationTargetException, InterruptedException {
/*
* selected eobjects
*/
monitor.beginTask("Creating abstract block", IProgressMonitor.UNKNOWN);
monitor.subTask("Checking the selected elements");
Set eobjects = new HashSet();
Iterator selIt = mySelection.iterator();
while (selIt.hasNext()) {
IGraphicalEditPart editPart = (IGraphicalEditPart) selIt.next();
EObject element = editPart.resolveSemanticElement();
if (element instanceof Block)
eobjects.add(element);
}
/*
* children
*/
childrenBlock = new LinkedList();
Iterator eIt = eobjects.iterator();
while (eIt.hasNext()) {
EObject element = (EObject) eIt.next();
if (eobjects.contains(element.eContainer()) == false)
childrenBlock.add(element);
}
/*
* all roots must be children block of the same block
*/
boolean flag = true;
parentBlock = null;
Iterator childrenIt = childrenBlock.iterator();
while (childrenIt.hasNext()) {
EObject block = (EObject) childrenIt.next();
//make sure it's a block
if (block instanceof Block == false) {
flag = false;
break;
}
//check all blocks have the same parent
if (parentBlock != null && block.eContainer() != parentBlock) {
flag = false;
break;
}
if (parentBlock == null)
parentBlock = block.eContainer();
}
if (flag == false) {
throw new InterruptedException();
}
monitor.subTask("Creating the abstract element");
View parentView = (View) someEditPart.getModel();
Diagram diagram = (Diagram) EMFCoreUtil.getContainer(parentView, NotationPackage.eINSTANCE.getDiagram());
String diagramID = ViewUtil.getIdStr(diagram);
AbstractTransactionalCommand createCommand = new CreateAbstractBlockCommand((Block) parentBlock, childrenBlock, diagramID);
try {
OperationHistoryFactory.getOperationHistory().execute(create Command, monitor, null);
} catch (ExecutionException e){

Thanks for the quick response Vlad. The example you provided was quite
verbose indeed, but I managed to get through it.
Thanks again.
