Hello

I am working on the implementation of GtkInfoBar [  
[http://developer.gnome.org/gtk/stable/GtkInfoBar.html](http://developer.gnome.org/gtk/stable/GtkInfoBar.html)].  
It uses GtkMessageType [  
[http://developer.gnome.org/gtk/stable/GtkMessageDialog.html#GtkMessageType](http://developer.gnome.org/gtk/stable/GtkMessageDialog.html#GtkMessageType)].  
This types are currently define under Gtk::MessageDialog.  
It seems awkward to use Gtk::MessageDialog::INFO while working  
with Gtk::InfoBar class.  
Should I redefine the type under Gtk::InfoBar (i.e. Gtk::InfoBar::INFO)  
?  
Should we have defined the type under Gtk::Message (non existing) module  
?  
What is the more rubyish way ?

In order not to break compatibility I would go with the redifinition:  
both Gtk::MessageDialog::ERROR Gtk::InfoBar::ERROR set to the same value  
(ERROR of GtkMessageType enum).

I am looking at Gtk::Dialog#add\_buttons in order to implement  
Gtk::InfoBar#add\_buttons.

Can someone explain me the choices made for this implementation ?

Why using gtk\_dialog\_add\_button and not gtk\_dialog\_add\_buttons ?  
Why freezing the object during the processus ?  
Why using 2 rbgtk\_dialog\_add\_buttons\_internal\_\* functions ?

I would like to avoid a wrong implementation for  
Gtk::InfoBar#add\_buttons  
and to understand a bit better the C code.
