EMF transaction for inserting a new Element in a diagram [message #1048264] Wed, 24 April 2013 04:31 Go to next message

My question concerns the adding of a Comment or a NamedElement such as a CallBehaviour for example in an active activity diagram through an emf transaction.

I would use the following skeleton for example:

// we suppose we have access to the serviceRegistry instance
TransactionalEditingDomain domain = ServiceUtils.getInstance().getTransactionalEditingDomain(serviceRegistry);
domain.getCommandStack().execute(new RecordingCommand(domain) {
public void doExecute() {
// do the changes here
}
}

I have downloaded your Papyrus source code. However I have no idea where to search an example for adding an Element in the active editor or some code that might help me?
I have grep "RecordingCommand" but I found a lot of occurences with some "@generated code" comments. Thus I decided to ask for some help.

How to deal with my need ?


Thanks

Hi, Alexandre,

Many (most?) such editing actions in Papyrus don't execute
RecordingCommands on the CommandStack but AbstractEMFOperations on the
IOperationHistory. They can be added to context menus using the
org.eclipse.ui.menus extension point, together with command handlers.
For an example, you might look at how the Add Child menu is implemented
in the Model Explorer.

HTH,

Christian

Hi, I managed to create an EMF object (an initial node) in an activity diagram with this code :

"...
/**
*
*/
private IElementType getElementTypeToCreate() {
return UMLElementTypes.INITIAL_NODE;
}

/**
*
*/
private Command buildCommand()
{
IElementEditService provider = ElementEditServiceUtils.getCommandProvider(container);
if(provider == null) {
return UnexecutableCommand.INSTANCE;
}

// Retrieve create command from the Element Edit service
CreateElementRequest createRequest = null;
if(reference == null) {
createRequest = new CreateElementRequest(container, getElementTypeToCreate());
} else {
createRequest = new CreateElementRequest(container, getElementTypeToCreate(), reference);
}

ICommand createGMFCommand = provider.getEditCommand(createRequest);

Command emfCommand = new GMFtoEMFCommandWrapper(createGMFCommand);
return emfCommand;
}

/**
*
*/
public Object executeCommand()
{
Command creationcommand = null;

try
{
ServiceUtilsForActionHandlers util = new ServiceUtilsForActionHandlers();
creationcommand = buildCommand();

util.getTransactionalEditingDomain().getCommandStack().execute(creationcommand);

return creationcommand.getResult();

} catch (ServiceException e)
{
e.printStackTrace();
}

return null;
}
..."

However it does not appear on the diagram. I have heard that I need to create the GMF part of the object and link GMF part with EMF part.

May you indicate me how I could get some examples or some help to create the graphical part of this item ?

Thanks for your help.
