How do I get more events from a wxListCtrl in a panel?

[bmoore at integrian.com]

Hello.

I am working on an application using wxPython that includes a panel
with a wxListCtrl populated with data received from a LAN attached
database.

I want the wxListCtrl panel to be loaded with a small amount of data
initially.  When the user moves the vertical scrollbar or press PageUp
or PageDown, I want to load the list view with new data from the
database.  I only want to load the wxListCtrl with a subset of the
database data at a time so the list view is responsive and will allow
for handling large databases.

The problem I am having is how to get events from the scrollbars or
the PageUp/PageDown keys, etc.  I can get events from selecting items,
etc.

Thanks,
Brian
