I'm attempting to create a drop down property for a custom widget I'm
creating. So when in designer and you scroll down to the custom
properties, under the regular widget properties, one of them would be
a drop down menu. The data to populate it will be coming from our API
and currently is a list of string-items. Yes, it would be treated
specially by Designer, since it's the only place it would be seen.

In the PyQt4\examples\designer folder, it carries a number of custom
widgets that will load into designer. The datetimeedit widget creates
a custom drop down menu property. The plugin pulls its information
from the QtCore libraries and from the QCalander Widget. Though I am
unable to find a better example or even explanation of how it's
actually creating that drop down menu.

No, I haven't, thanks. That might step in the right direction. I can't
run it right now, so I'm not sure if it is putting a spinbox as it's
property or just the value from the spin box.
