Re: How do I...

[Eric Harlow <linuxgeek yahoo com>]

The button is really a label inside a container - just happens that
the container is a button.  You can change the label by doing
something like:

    button = (GtkButton *) widget;
    label = button->child;

    gtk_label_set (GTK_WIDGET (label), "Blah");
