Hi,
I am having a very strange problem with my GEF editor. For example in my
connection editpart I configure everything to allow deletions using the
folowing code:
installEditPolicy(EditPolicy.CONNECTION_ROLE,
new ConnectionEditPolicy() {
protected Command getDeleteCommand(GroupRequest request) {
return new ConnectionDeleteCommand(getCastedModel());
}
});
If I comment this out, the "delete" Context-Menu entry disapears.
Unfortunately the entry is gay and can't be selected. Normally when I select
a new edit part the getDeleteCommand is called automatically in this case it
is not. What could be wrong here? So I have to toggle any switch? My Editor
is a MultipageEditor containing a GEF editor as one of its Pages.
Tanks in advance,
Chris

....the usual problem with MPEs. Well, you have to propagate selection
changes in the multipage editor
to your gef sub editor:
1. MPE should implement ISelectionListener
2. add something like this to your MPE:
public void selectionChanged(IWorkbenchPart part, ISelection selection)
{
ISelectionListener listener = (ISelectionListener)myGEFEditor;
listener.selectionChanged(part, selection);
}
Your GEF editor should now update its selection actions.

After 2 endles days of "no internet" becaue of isp-problems I finally couls
read yout tip. Thanks for your hint. It gave me a point in the right
direction.
What I had to do additionally was
1. to register the MultipageEditor as SelectionListener.
getSite().getWorkbenchWindow().getSelectionService().addSele ctionListener(this);
2. Implement the ISelectionListener allmost as you suggested:
public void selectionChanged(IWorkbenchPart part, ISelection selection) {
if (this.equals(getSite().getPage().getActiveEditor())) {
if (netEditor.equals(getActiveEditor()))
netEditor.selectionChanged(getActiveEditor(), selection);
}
}
}
3. to override the selectionChanged method in my Editor.
public void selectionChanged(IWorkbenchPart part, ISelection selection) {
super.selectionChanged(part, selection);
if (this.equals(part)) { // Propagated from MyMultiPageEditor.
updateActions(getSelectionActions());
}
}
Hope this helps anyone ...
