Re: Argument passing / GTKTextView

-

you can either use gtk_object_set_data() on the widget, to set associate
a key string with a gpointer data element:

gtk_object_set_data(GTK_OBJECT(widget),"struct",structure);

then in the callback:

structure = gtk_object_get_data(GTK_OBJECT(widget),"struct");


or pass a structure containing everything (gints,other structs, etc)
