Hi Folks,

I'm looking to implement a custom control class that will display a  
custom view into a stack of customer buttons (canvases).  What I want  
to do is to be able to create zero to n buttons in a scrollable  
view.  The control must be able to add of remove buttons and provide  
vertical scrolling to allow the user to access all of the current  
buttons, regardless of the number.

I've examined doing this with a scrollable canvas, but 'm concerned  
with the flicker that I witness on Windows and Linux.  This led me to  
a container control as the host control, but I'm lost as to how to  
implement the vertical scroll operation.

Anyone using container controls for a similar function or have ideas  
of how to implement this?

Thanks,

Tim
