[news.eclipse.tools] Plugin Registry Notifications?

["Ted Stockwell" <_nospam_emorning@xxxxxxxxxxxx>]

Hi,

Is there a way to receive notification when a plug-in registers a particular
extention?
Or, is there a way to receive notification when the plug-in registry changes
at all?

Here's why I'm asking...
I have a set of tools that I am integrating into Eclipse.  I am creating a
plugin for each tool.  I have a main plugin that declares a perspective for
viewing all my tools and in that perspective I have a view that lists all
the resistered tools.  This view kinda looks like the Outlook Bar in MS
Outlook.
Anyway, I'm wondering how I can update my view if a new tool is loaded
dynamically (due to the user performing an update, or dynamically importing
a new plugin that declares an extension of my tool set).

thanks,
