Re: GTK PROGRAM STRUCTURE

[Flavio Ribeiro <flavio hackpalace com>]

Try creating structures that cointain important parts of your user
interface and making functions that initialize these structures. Declare
instances of the structure inside main() and call handlers with a
pointer to the structure (or to an array of relevant structures) as the
argument.

This way the variables won't all be global and the widgets will be
grouped in blocks.
