[Memphis.pm] GTK-Perl and signal handlers

[Big Ed]

Well.. I've only used GTK+ Widgets in C, but I think I can help you here:

With the other widgets, create signal handlers with express purpose of 
updating a standalone struct with the necessary info.  When your signal 
function is called on the button, reference the struct for retrieving 
necessary data from it.  You could do the same with a class or something of 
that nature ($obj->set_text('blah'))  I really need to look back into a 
little GTK stuff, since it's been months since I've done any GTK coding 
lately.  Also, the signal handlers do allow for passing additional args into 
the call.  You should be able to pass a $ref off.

If this doesn't seem correct, or you want me to post an example, let me 
know.
