Since <deck> elements are implemented in XBL, there is no easy way to manipulate an instance from C++ (to change the selected child, for instance). Having the XBL binding implement a standard xpcom interface would provide a convenient way to manipulate the element from C++.

What I propose is the creation of an nsIDOMXULDeckElement interface and corresponding .idl file, and modification to the deck binding in general.xml to implement it.

I have attached an idl file and a patch for the XBL. I am currently using this method to manipulate a <deck>, and it seems to work fine.

Reproducible: Always

If you want somebody to have a look at your patch, you'll have to set its review flag to a Toolkit peer such as Neil Deakin (see <http://www.mozilla.org/projects/toolkit/review.html>).

It'd also help if you could post both changes in the same patch (just hg add the IDL before diff'ing).
