Notes

To exploit all the features of XView-movie, the OpenLook window manager must used. These features include four-corner sizing and footer messages. This window manager is distributed as part of the X Windows package.

Animation is tricky in XView. The volume of draw commands can overwhelm incoming interaction requests. The XView toolkit provides an alarm clock to draw repeatedly an image. Programmers should use this in place of a filmloop.

One disappointment in this version of XView is lack of extensibility. I would like to create a custom control object copied and modified from exiting objects, e.g. a two-ended slider, with an XView-like subroutine syntax, but this is not currently possible.
