There's a command for communicating with modules, SendToModule, but I think
each module has to be programmed individually to interpret and respond to such
an event (and most don't). There's no general infrastructure for dynamic
reconfiguration. Normally you have to restart a module to get it to
recognize new configuration.
I've developed a rough patch (on v. 2.4.3) to do this sort of thing with
FvwmPager, for my own purposes. It can respond to the following three messages:
SendToModule FvwmPager Pixmap <pixmap>
SendToModule FvwmPager Hilight <color>
SendToModule FvwmPager HilightPixmap <pixmap>
Here's the patch; maybe it'll be useful to you.
