Hi,
I want warn the user with a message(Yes/No), after the option (Delete from
Model).
It is important to me because it delete the complete tree behind this
element.
Now I look for a way in *BaseItemSemanticEditPolicy.
My question is:
Where can I implement this message?
Which return command? (Null gives an error)
Thanks
Jürgen

I think that you can implement in the YourContainerEditpart, where
YourContainer is the element to contain your element to delete.
In this class, you have to overwrite the handleNotificationEvent, and ask
(in a dialog) to deleting.
If the user click "no" you can do a undo with your oldvalue from your
notification.
Only it?s an idea, i am not sure that it work.
Luck!

Somehow this has a nasty side effect for me.
getDestroyElementCommand() is called when I do a simple select and it brings
up the yes/no dialog!
It is not able to delete.
When I do a delete, the dialog shows up and then I'm able to delete.
I am using europa eclipse with java 1.6.0.3. Windows 2003.

My fault. Not everything I said is true...
Actually, SemanticEditPolicy *does* show a confirmation dialog when an
element is about to be destroyed.
The dialog doesn't show up after selecting "delete from model" in the
popup menu, because DestroyRequest#isConfirmationRequired is always (?)
set to false. This makes sence, because the user explicitly sais "delete
this element from model" and you don't want to annoy users with
unnecessary dialogs. On the other hand, you might as well take up the
position, that users never really know what they are doing ;-)
As a workaround, I've overridden SemanticEditPolicy#shouldProceed inside
xxxBaseItemSemanticEditPolicy:
protected boolean shouldProceed(DestroyRequest destroyRequest) {
IPreferenceStore store = (IPreferenceStore)
((IGraphicalEditPart)getHost())
.getDiagramPreferencesHint().getPreferenceStore();
//check preferences whether to prompt or not
boolean toggle = store.getBoolean(
IPreferenceConstants.PREF_PROMPT_ON_DEL_FROM_MODEL);
((DestroyRequest) destroyRequest).setConfirm(toggle);
return super.shouldProceed(destroyRequest);
}
One problem remains. If a node has some connections attached, a
confirmation dialog will be opened for every single connection.

Well, I think it would be better to return
PromptingDeleteFromModelAction inside generated
xxxContributionItemProvider (wich unfortunately is internal) and
register 'deleteFromModelAction' against this provider.
plugin.xml:
<extension point="...contributionItemProviders">
<?gmfgen generated="false"?>
<contributionItemProvider
class="x.x.x.diagram.providers.xxxContributionItemProvider" >
<Priority name="Low">
</Priority>
....
<popupContribution
class="org.eclipse.gmf.runtime.diagram.ui.
providers.DiagramContextMenuProvider">
<popupStructuredContributionCriteria
objectClass="x.x.x.diagram.edit.parts.xxxEditPart">
</popupStructuredContributionCriteria>
<popupAction
id="deleteFromModelAction"
path="/editGroup">
</popupAction>
<popupPredefinedItem
id="deleteFromModelAction"
remove="true">
</popupPredefinedItem>
</popupContribution>
....
</extension>
xxxContributionItemProvider.java:
protected IAction createAction(String actionId,
IWorkbenchPartDescriptor partDescriptor) {
if (actionId.equals(PrintPreviewAction.ID)) {
return new RenderedPrintPreviewAction(
new EnhancedPrintActionHelper());
} else if (actionId.equals(ActionIds.ACTION_DELETE_FROM_MODEL)) {
IWorkbenchPage workbenchPage = partDescriptor.getPartPage();
return new PromptingDeleteFromModelAction(workbenchPage);
}
....
}
Enough confusion for today... I'm out :-)

I eventually came to the same conclusion.
Only PromptingDeleteAction.createCommand knows about all the selected edit
parts.
In my current implementation a Y/N box is displayed for every selected
EParts. If you select N for any of the EParts the whole group is undone.
You dont have individual Y/N control yet you are asked for every
individual EPart!
