Thanks for the information. The new API looks like the kind of thing I'm
looking for. But I'm still a little confused as to how to use it to
achieve what I want. Is there a recommendation as to where/when (i.e.,
class/method, listener event, etc.) to hide the editors, and where/when to
re-show them? The API documentation says that getEditorReferences() does
not return hidden editors. So how do I get the list of hidden editors
that I want to re-show when a perspective is being re-shown? Note that I
don't necessarily want to re-show all hidden editors, as there may be some
hidden editors associated with perspectives that are not being re-shown.
Any advice would be appreciated!

Thanks for your help. I'm a novice when it comes to Eclipse RCP
development, so I was wondering if you could point me in the right
direction. What is the recommended way for me to set it up so that I can
react to perspective events? In other words, do I add a listener to
something? If so, what type of listener, what would I be adding it to,
and when would I add it? (i.e., during workbench initialization?
workbench page initialization? what classes/methods represent those
actions in the workbench lifecycle anyway?)
Also, is there a method I can call that will return all of the open
editors, including hidden ones?
Thanks again for being patient with me!
Regards,
Dave

Hi Dave,
Try these as a starting point:
PlatformUI.getWorkbench().getActiveWorkbenchWindow().addPers pectiveListener(listener);
PlatformUI.getWorkbench()..getEditorRegistry()
Best regards,

This API was added for the most hard-core of hard-core RCP developers. It is not how we recommend using editors and the editor areas (the questions you've posted are just the beginning, believe me 
That being said, I would consider writing your editor+perspective management code in its own plugin. Try and limit what else it does, and then to get the behaviour your want (in a RCP app) you would look at starting up your management functionality in your workbench advisor (it has post startup methods).
You need to listen to callbacks in the IPerspectiveListener* methods, and you might even need an IPartlListener2 listener in order to tell when editors are opened/closed.
