At a first glance to the docs, i think gtk_emit_signal could be the function
to go for, but i didn't get it work so far.
What do i have to do to define a user_defined message that can be sent to a
widget hirarchie, and for which widgets can register?
I don't know, But i think g_object_notify() maybe the Right Thing (tm).
I'm not sure,
This is probably correct. It should be noted, however, that GTK doesn't
use message passing. Instead it uses signals and callback functions.
I know you are trying to avoid this, but most gtk programs I've seen
access widgets directly from within the framework of the dialog box. I
don't believe that this is incorrect or violates any paradigm. Since
gtk apps are generally single-threaded (at least the thread that runs
the gui), you can directly access another widget and call a method on it
from anywhere that you have a pointer to a widget. Why would this not
be a good idea in your case? Perhaps if you told us a little bit about
what you are doing then we can find a good solution for this.
