Disabling callbacks

["K. M. Hawarden-Ogata" <hawarden duke ifa hawaii edu>]

Hello all.

I was wondering if anyone has any ideas about this:

I have a widget that calls a callback, which in turn changes a variable.
Fine.

Going the other way, I change that variable and I want to undate (redraw)
the widget to reflect the new state of the variable, without triggering the
callback.

I read the documentation about signals and blocking them, but it's very
sketchy. Does anyone have an idea about what I need to do?

Any help would be much appreciated!

Thanks, Miranda
