treeview and scrolling

[danny van elsen <danny van elsen skynet be>]

hello all,

I would like to modify the scrolling behaviour of a treeview: I have 
hundreds of thousands of rows to show, and the treeview is taking far 
too long to fill up all of the data.

So what I want to do is: instead of loading all data into the treeview, 
and then use the built in scrolling behavior, I would like to add my own 
scrolling, and to only add the data to the treeview that is currently 
visible.

What would be the best way to do this?

- derive a new class from treeview, place it in a scrolledwindow, and 
act on the adjustment callbacks?
- place a treeview together with a scrollbar in a window? Should that be 
a frame or a Viewport?
- something different?

thanks for your advice,
Danny.
