<para>
Create a new GNOME application status bar.  If <parameter>has_progress</parameter> is
<literal>TRUE</literal>, a small progress bar widget will be created, and placed on the
left side of the appbar.  If <parameter>has_status</parameter> is <literal>TRUE</literal>, a status bar,
possibly an editable one, is created.
</para>
<para>
<parameter>interactivity</parameter> determines whether the appbar is an interactive
"minibuffer" or just a status bar.  If it is set to
<literal>GNOME_PREFERENCES_NEVER</literal>, it is never interactive.  If it is set to
<literal>GNOME_PREFERENCES_USER</literal> we respect user preferences from
ui-properties. If it's <literal>GNOME_PREFERENCES_ALWAYS</literal> we are interactive
whether the user likes it or not. Basically, if your app supports
both interactive and not (for example, if you use the
gnome-app-util interfaces), you should use
<literal>GNOME_PREFERENCES_USER</literal>. Otherwise, use the setting you
support. Please note that "interactive" mode is not functional now;
GtkEntry is inadequate and so a custom widget will be written
eventually.</para>
