You can't, that's the point.

But you can make them vanish with two methods depending on what you want:

 * unregister them, makes the view vanish from the task navigator
 * remove them from the appview, implies the above

The first one keeps the view inside the HildonApp, so you can simply
register() it again to make it visible in the task navigator again.

Example:

If you want to make the cross to look like the appview was closed, do
a signal connect for the HildonApp's "delete-event" signal and in the
callback check if the appview you want to "close" is active
(hildon_app_get_appview() gives the currently visible one),
hildon_app_unregister_view() or just removing it from the HildonApp
with gtk_container_remove() will make the view vanish from the task
navigator. Return FALSE from the callback when you really want to
quit, and TRUE when you just remove the AppView.

Disclaimer: I haven't tested this, but it "should" work
