Hope you guys don't mind, but I have a slightly different question
about implementing widget colors. I never knew this capability
existed, so I figured it would be great to use for some GUIs I wrote
that have lots and lots of drop-lists and cw-fields, but only a handful
of which the user needs to actively change or look at each time. I got
it to work fine for a simple test case with several buttons, but when I
apply it to my real code, I can only use major colors like red, green,
blue, etc (I'd like to use MistyRose, it's not so gaudy as the
others). Any ideas why?

Years ago I wrote a "color button" widget that was really
a draw widget disguised as a button. (But it returned
button events, so it was just a drop-in replacement for
button widgets.) This would work so much better these
days with object graphics.

Hi,
I've achieved a workaround for this using Motif X-windows under OpenVMS.
This entailed creating two bases in the same position. Each of these bases
contains an identical button, but with a different RESOURCE colour for its
background. The event handler for the button then maps/unmaps the relevant
bases to give the effect of changing button colour.
I hope this can be of some use. I might be able to find a working copy id
you wish to e-mail me.
Regards,
Ian

As far as I know, if you are working on a system which uses X windows
(unix) you can use the keyword resource_name when defining the widget.
The help file gives an example of changing the color of a button this
way. I'm not sure if this will allow you to change the color once the
button is pressed, however.
