Re: Object Orientation in GTK

[exp120 physik uni-kiel de (R. Bock)]

Hi!
Most widgets and signal handlers can hold additional information which may
be used by your functions. It is usually a gpointer called user_data. You
can put all the information you need into that pointer (maybe using structs).
This should be sufficient to avoid global variables.
