Deleting a part from a model [message #1067452] Mon, 08 July 2013 15:03 Go to next message
Eclipse UserFriend
I have a situation where I use the PartService's createPart() method to create a part from a PartDescriptor. The PartDescriptor indicates that the part is "multiple", "closeable", and "dirtyable".

My problem is that when I then close the part, I see in the workbench.xmi that there is still an entry for the part, with toBeRendered="false". That orphaned entry isn't really doing me any good because I don't want to retrieve it again.

Is there a way I can tell the model to remove the part entirely when it is closed? I'm sure there must be, but I can't find the API in either the EPartService or EModelService.

Thank you.

My, how often the answer comes just after posting to a forum....

Calling setParent(null) on the part did the trick.

The real solution is to tag the part with "removeOnHide" and the
framework will remove the instance from the model when closed.

I put removeOnHide into eclipse help (F1) but it finds no matches. Is there a list of these tags somewhere. I am assuming I just add it to the Tags on the supplementary tag of the part descriptor.

It is on the EPartService. I currently don't know if this is documented
in the wiki else this should be done there. Naturally also the tooling
should know the tags available - you should file a bug against it unless
there's already one.
