Re: Panels and Pads

[Bryan Christ]

Here's what I would suggest...

1.  Use windows with panels (as should be done).
2.  Do all your heavy work on a pad.
3.  When you need to display a portion of the pad, use overwrite() or
copywin() to copy the contents to the window.

If you use overwrite(), there is one caveat.  Pads and windows operate
in absolute coords.  If you need to copy from 0,0 on the pad to 0,0 on
the window, but the target window is positioned at 4,4 (on the screen),
you need to first move the pad to 4,4 and then copy the contents using
overwrite().
