let`s see.
you can send event message with NULL in target widget property, so it
will receive *every* widget (broadcast). Before that you can register all
animation widget on their init. So, if you need to update only certain
widget, you send the update event, specifying its ID in userdata property.

in my case, I have a workspace widget(background) that contains map and control
widgets. map contains object widgets. On idle event, I update all
animation widgets by sending message "time to update, guys" as broadcast.

By that, I have sync`ed animation to about 30 frames/sec. I draw all
animation widgets then update the whole screen.

I hope it helps.
If you have more questions, be my guest! :P

Kind regards,
       taurus
