How to remove Parent interface from interface?

[tomte]

Hello,

first it took me quite a while to add the "Parent" interface java.util.Observer to my interface MyObserver.
- Set Element Parent dialog is available only from digrams, not from the project browser.
- So I added it to a dummy diagram first and called the Set Element Parent dialog (pretty uggly for such an important OO feature).

This way MyObserver extends Observer now in the diagram (hopefully in code too later).

Then I noticed that I added it to the wrong interface, say to MyNonObserver.  

The inherited interface shows up in the diagram correctly, but it is not even shown in any property dialog.

So how can I remove the Parent interface from that wrong  interface now?

Any hints would be appreciated ...

Best regards
Thomas

Open up the Set Element Parent dialog again.

Oops, indeed ... - there is the parent  again, and not in the properties of the interface.

Thanks a lot, Simonm, for your fast and helpful reply!
