[pygtk] Sizing textviews in a vbox question

[James Simmons]

I'm working on a program for reading Project Gutenberg etexts and I want 
to add an annotation feature.  To do this I have created a Vbox and have 
added two gtk.ScrolledWindows to the VBox.  Each ScrolledWindow contains 
a gtk.TextView.  Now what I want to happen is the top text view contains 
a read-only single page of a Gutenberg etext.  The bottom text view 
should be editable, so the reader can make notes on the page visible in 
the upper window.  I want to be able to hide and show the bottom text 
view and scroller so the user only sees it when he wants to annotate a page.

Everything I have described above works.  The problem is, when the 
bottom textview and scroller are visible they is exactly the same size 
as the top textview and scroller.  What I want is for the bottom 
textview and scrolller to take less than half the vertical space in the 
window.  No more than 30% of the window height and perhaps less.  The 
annotation area is less important than the reading area above so the 
vertical size should reflect that.

So how do I go about making the bottom textview shorter than the top one?

Thanks,
