No, that was a really misleading waste of namespace by me ;)
I mean the IDL KfmView interface (not the current KfmView class) as common
parent interface for all possible view types.

Ah, well, that's another idea.
In contrary to this I thought of views as even more separate components, not of
a KfmView (like the _current_ class) containing ViewContent objects and
displaying them (well, the name isn't that bad :) but instead of views as
completely independend objects which inherit from an KfmView interface to
provide a common kind of API to access a view.
(this way it'd be possible for apps to create their own kfm views and "add"
them to konqueror (here as KfmMainView) . For example KMail might provide a
kmail-kfm-view to process mails "inside" konqueror when browsing the web)
In addition I think we might add a fourth (fifth?) part kfm view which does
nothing else than embedding other apps parts (for apps not wanting to "use" a
common kfmview parent interface) .
