Create two behaviours to add an element in an EMF editor [message #106063] Fri, 04 January 2008 14:43 Go to next message

Hi,

I have a problem with the creation of my elements in my EMF editor.
When I create an element, I would like to create two children.
So I modified the 'create' method in the factory class and called the
'create' methods of the two children.
But when I open a file which has already an element with its two children,
there are more than two created elements (the loaded elements and the
elements created in the factory class).
I would like to know how I can modify the behaviour of my editor in order
to have the two loaded elements when I open the editor, and two
default children when I create a new element. Maybe should I modify the
action of the menu bar ? I find an easy way to do it.

Thanks,

Marion

Marion,

Next time you should ask EMF questions on the EMF newsgroup.
news://news.eclipse.org/eclipse.tools.emf

You can specialize the wizard itself so that when you create a new
object in createInitialModel you create one with additional children.
In terms of create commands within the editor, you can specialize the
collectNewChildDescriptors method in the XyzItemProvider to create new
instances that have children or have other features already set on them;
you don't need to use commands for doing that prepopulation.
