[wxPython-users] Scrollbar help with DynamicSashWindow

[Danny Shevitz]

let me see if I understand  your response.

Instead of putting the TreeCtrl inside each window created by the DSW,
I should put a panel in each window. If the panel is large enough to hold 
the tree, then the panel gets clipped but the
TreeCtrl newer needs to draw it's own scroll bars. At that point I use the 
DSW scrollbars to move the panel around.
Is this right?
