GtkStatusbar and DGSEAL_ENABLE

[Carlos Pereira <jose carlos pereira ist utl pt>]

Hi there,

In order to conform with -DGSEAL_ENABLE, I replaced this old code:
gtk_misc_set_alignment (GTK_MISC (GTK_STATUSBAR (statusbar)->label), 
0.5, 0.5);

by this new one:
hbox = gtk_statusbar_get_message_area (GTK_STATUSBAR (statusbar));
label = GTK_WIDGET (gtk_container_get_children (GTK_CONTAINER 
(hbox))->data);
gtk_misc_set_alignment (GTK_MISC (label), 0.5, 0.5);

It compiles and runs fine, and it does what is expected to do.

Of course this code only works because the label is the first children 
of the statusbar hbox container (the first node of the statusbar hbox 
GList). If that changes in the future, this code will get broken...

Perhaps we could have a function:
label = gtk_statusbar_get_label (GTK_STATUSBAR (statusbar));

This way GTK developers could futurely change the inner workings of 
GtkStatusbar without affecting user code that needs access to the Label.

Regards,
Carlos
