Re: GtkLabel trouble #2

[Esteban Quijano Vincenzi <equijano videotek tv>]

So, is it fair doing something like this?

gchar *text;

text = GTK_LABEL(label_widget)->label;

(I know we should access all data members by its interface, and not directly)

> Second, passing &text won't work properly either. If text is an array, you'll get a compiler error since gtk_label_get will try to assign a new pointer value to it, which is illegal. If text is a pointer holding calloc()ed memory, that memory will leak because gtk_label_get will assign it's own block of memory to text :).
