I know, I know. =) I'm just showing step by step the construction of an
embeddable. And the first interface it must implement is Embeddable. Thank
you for the note, though.

And it will. And you can bet that I will be bothering you with more
questions about Printing. =)

Oh! I completely missed that. Thank you very much! I works!

I'm going to show this code to a non-GNOME programmer guy. So, I want it
the simplest thing on earth. =)

Now, help me understand, why is this sub-optimal and ugly?  Because the
connected activate signal callback would not be the default signal
handler?

<set-rude-mode>
And if this is ugly... why does bonobo_view_new exist anyway?
</set-rude-mode>
