Scrollbar help with DynamicSashWindow

[Danny Shevitz]

I'm using a DSW to present multiple views of a tree. The DSW has it's own 
scrollbars.
Currently as the length of the tree increases, the TreeCtrl puts up it's 
own scrollbars, So I have
two scrollbars on the rhs.

I know DSW's have scrollbar events as in the demo. What I don't understand 
is how
to hook up the DSW scrollbars to the TreeCtrl.

For the demo, the operative lines are:
self.SetVScrollBar(v_bar)
self.SetHScrollBar(h_bar)

But there are no Set[V|H]ScrollBar methods for a TreeCtrl. For a TreeCtrl 
there is
a SetScrollbar method, but that just changes the position, not the window.

So, I'm stuck. What am I supposed to do?

Thanks,
Danny
