277) How can I create a transparent widget?

[Last modified: June 95]

Answer:  The simplest way is probably to use the SHAPE protocol extension.
The xeyes, xlogo, and oclock demo programs in X11R5 (and later) are good
examples of using SHAPE with widgets. You should be able to use the same
techniques with your Motif widget subclasses.

Ken Sall (ksall@cen.com) adds: The official name for this extension is "X11
Nonrectangular Window Shape Extension". If you have X11R5 source, the Shape
extension document is $TOP/mit/hardcopy/extensions/shape.PS or
$TOP/mit/doc/extensions/shape.ms. In X11R6, see
$TOP/xc/doc/hardcopy/Xext/shape.PS or $TOP/xc/doc/specs/Xext/shape.ms.  There
is also a terse man page: $TOP/mit/man/Xext/XShape.man (X11R5) and
$TOP/xc/doc/man/Xext/XShape.man (X11R6).
