Answering my own question since I know there are interested people out
there...
I found that when I put a big text widget inside the XEmbed'ed GtkPlug
container instead of a big drawable canvas, it was able to receive
focus. Digging into the GTK source code, I noticed that it calls
gtk_widget_grab_focus() when it receives a button press event. So I did
the same for my canvas widget when the user clicks in it, and it seems
to work. The widget retains focus until the user clicks outside of the
window.
Wow, I can't believe that looking at the source actually helped. :)
