[MonoDevelop] Design Time Properties for Custom Controls

Much is possible via the objects.xml resource format. It's essentially
undocumented, unfortunately. But if you want to get an idea of what's
possible, you can look at:
http://anonsvn.mono-project.com/viewvc/trunk/monodevelop/main/src/addins/MonoDevelop.GtkCore/libstetic/wrapper/objects.xml?view=markup
Your example of an enumerated property I believe is automatically
supported by adding an enum element to the document, like those
specified at the bottom of the file.
There is some syncing capability built into stetic/MD to produce and
update an objects.xml file, but it is off by default since most people
do not want or need to get into this detail. Simply creating an
objects.xml file under the gtk-gui folder in your MD project should
enable this sync capability. I don't believe it currently syncs enums,
though.
Stetic is not as full-featured and easy to use as VS, but then again,
it's had probably .0001% of the developer hours invested in it that VS
has. It also hasn't been seen much exposure to custom widget
development thus far, so feedback to make it better, and of course
patches to do so as well, are always welcome.
