DocShell/Window targeting: Difference between revisions

Window targeting is used for both <code>&lt;a target="name"&gt;</code>  and for <code>window.open(url, name)</code>.  The process works as follows:

# Once we have a target docshell, we proceed to do the load in it by calling either <code>LoadURI</code> (in the window watcher, for the <code>window.open</code> case) or <code>InternalLoad</code> (in docshell, for the targeted link case).

I want to change step 8 to do the following instead:  If no docshell with the given name is found, get a "window provider" or something service and ask it for a new rendering area (nsIDOMWindow, probably, or nsIWebNavigation).  Pass in the initial target docshell (or its DOMWindow?) to this service, so that it can create new tabs, eg, in the right places (in the same window).  The service implementation would live in the embedding app (in toolkit or xpfe in Firefox/Seamonkey, for example) and would be free to return whatever window/webnavigation it wants.  If it returns nothing, we'd fall back to opening a new window via the window watcher as we do now.

We need to do something to fix steps 5 and 7.
