[Gtk-sharp-list] GConf Sharp question

[Jeff Perrin]

I'm currently in the process of learning how gconf-sharp actually works,
and came across a little issue in the test app I created.  I have a
working form that alters the gnome background properties (from schema
file "desktop_gnome_background.schemas").  However, it seems that a
couple of the properties from the schema file (color_shading_type,
picture_opacity, and picture_options) are of type 'string', when the
available options would be better off stored as an enum of strings. 
Here's a relevant section from the sample.schema file in the
samples/GConf dir of gtk-sharp CVS:

<schema>
        <key>/schemas/apps/gconfsharp/sample_app/the_first_enum</key>
        <applyto>/apps/gconfsharp/sample_app/the_first_enum</applyto>
        <owner>sample_app</owner>
        <type>string</type>
	<cstype class="Sample.Names">enum</cstype>
	<locale name="C"></locale>
	<default>Bob</default>
</schema>

and here's an example of what I see in desktop_gnome_background.schemas:

 <schema>
        <key>/schemas/desktop/gnome/background/picture_options</key>
        <applyto>/desktop/gnome/background/picture_options</applyto>
        <owner>gnome</owner>
        <type>string</type>
        <default>stretched</default>
        <locale name="C">
        <short>Picture Options</short>
        <long>Determines how the image set by wallpaper_filename is
    rendered.  Possible values are "none", "wallpaper", "centered",
"scaled",
    "stretched".</long>
        </locale>
 </schema>

Notice the line:<cstype class="Sample.Names">enum</cstype> in the first
example.

Therefore, how would I bind the available options from the second
example to something like a drop down list, which would be far more
user-friendly (as opposed to using a Text Entry).  Take a look at the
screenshot here:

Hopefully someone can understand what I mean and give me some solid
feedback...
