is this something that I must do for -every- combination of required
data for all my callbacks? Or should I just create one enourmous
structure and set only the needed elements in that?
Also, some of this data isn't stuff that I know how to access
-anywhere-. I used glade to create the interface, so, for example, if I
want to use a button to save what was typed into a text field, how do I
retrieve the text to be saved? I can't access the textbox widget
itself, because that was created by glade in the "interface.c" file and
I have no way to store a pointer to that widget. If I edit interface.c,
glade will just overwrite my changes when I edit the interface.
Is there a way to retrieve pointers to a specific widget from within the

Then, in your callback function, just retreive the data by casting
gpointer* to the proper typedef.

I often have problems like these. I have a button whose callback needs
data about some other widget elsewhere in my program. In general, how
do I pass this data to my callback or retrieve the data from within the
