[perl-win32-gui-users] Window / Dialogbox scrollbars

[kenneth . dahlitz]

In the latest WIN32::GUI ver0.0.671 it indicates that the scrollbars have
been implemented for
Windows and Dialogbox's.   I cannot seem to figure out how to get the
client area of the window
to scroll.  I have some example code below.  Could someone please explain
to me how I can
get this to work.  My pea-brain just doesn't seem to grasp what I need to
do.
Thanks in advance for any guidance........................


 use Win32::GUI;
 use strict;

 my $operation;
 my $position;

 our  $mainwin  =  new Win32::GUI::Window(
