I'm trying to implement nsWeakPtr as a member variable of my class.
OK.
A snippet is located here: http://pastebin.mozilla.org/457 (23 lines of c++)
The GetMyNode looks fine (though I'd null-check mMyNode and then use CallQueryReferent, and skip the manual refcounting.
SetMyNode is also OK, though I'd use do_GetWeakReference instead of the deprecated NS_GetWeakReference.
But all this only works if aMyNode implements nsISupportsWeakReference. DOM nodes generally don't.
PS. In my sample it should be "public nsSupportsWeakReference" where it says "public nsISupportsWeakReference"
I'm not even sure why that's there... You don't need that to have an nsWeakPtr member; you need that if you want someone else to hold an nsWeakPtr to your component.
