467928 - folderpane extensibility: provide a mechanism for an extension to switch treeview on mode change

Status: NEW

(Thunderbird :: Add-Ons: Extensions API, defect)

Description

[David Ascher (:davida)]

some extensions may want to display completely different things in the "folderpane".  We should figure out and document how they can switch different treeviews on switching to their mode (and switching the original back in when switching back to a core mode).

Jminta talked about firing events on mode setting, but I don't know how that would allow resetting of the tree view on reversal back to a built-in mode.

I think the solution here is just to require our internal standard tree to use the same hooks we encourage extentions to use. That is, add an event listener and if we recognize the mode as a built-in one, ensure that our tree view is what it should be.

Not sure how much this is wanted, but it certainly wouldn't be able to change in 3.1.
