Hi,
I'm not a specialist of gef so don't trust my advices too much.
When the method parentModel.add(childModel) returns, the change events =

called, and so the EditPart hierarchy is now up to date with the new sta=
te =
of the model, if I make no mistakes. So at the end of the paste routine,=

by calling the method getEditPartRegistry() on the EditPartViewer, you c=
an =
get a map between the model objects you just have added and the EditPart=
s =
wich have just been created for them. In this map, the model objects are=

the keys to the EditParts, so you can get the EditParts. Once you have t=
he =
EditParts, maybe you could call on them the method setSelection(...) ? I=

know that method fires events to notify the selection change so everythi=
ng =
would work fine.
Let me know if this was the good solution,
with best regards,
r=E9gis

I simply keep track of the model elements in my copy action and then
call a method within my editor which calls the getEditPartRegistry for
each and build a list of Edit Parts and then do the following for the
edit part list
StructuredSelection selection = new StructuredSelection( parts );
getGraphicalViewer().setSelection( selection );

Perhaps I misspoke. Here is what I am doing. My copy action has the
following run():
public void run() {
List copiableObjects = getCopiableObject( getSelectedObjects() );
if ( !copiableObjects.isEmpty() ) {
Clipboard.getDefault().setContents( copiableObjects );
}
}
The getCopiableObject() does a check based on the rules of my model to
determine if the objects that the user has selected in the editor are
indeed copiable. For instance, I filter out connections since they
don't make sense to copy and paste. I place the EditParts in the clipboard.
My paste action then has the following in its run():
public void run() {
List parts = new ArrayList();
List commands = getCommands( getClipboardContents() );
for (Iterator iter = commands.iterator(); iter.hasNext();) {
Command cmd = (Command) iter.next();
// cache the editpart for later selection
if ( cmd instanceof CompoundCommand ) {
CompoundCommand compoundCmd = (CompoundCommand) cmd;
AddCommand add =
(AddCommand)compoundCmd.getCommands().get( 0 );
parts.add( add.getChild() );
}
execute( cmd );
}
((MyEditor)getEditorPart()).selectProcessors( parts );
}
The getCommands() method then walks through the contents of the
clipboard and creates the appropriate commands. These include commands
to add a new object (AddCommand), link two objects (if their sources
were linked), and place objects (I shift them by a set amount relative
to the source). Since the command that creates them is a
CompoundCommand (AddCommand and SetConstraintCommand) I check for those
and cache the new model (even though the list isn't named properly at
the moment).
HTH,
Phil

phil,
that is very interesting. i appreciate the insight. you do an add
command on the clipboard objects. doesn't that imply that you will have 2
models in the diagram actually tied to the same "real" model? that is why
i clone the model before doing an add command. am i missing something?
also, what do you mean by "linking" two objects? i am not familiar with
this.
again thanks,
steve

No, I do not have two objects tied to the same model. I have a copy
constructor in my model that does the "cloning." That is all done in
the getCommands() method.
linking = connecting. Basically, if two elements in the diagram that
are connected are copied, the pasted elements are also connected.
