[GRASS-dev] can wxPython GUI handle order of options for v.type and alike?

I've only done a limited amount of work on the autogenerated properties
dialogs. Daniel has done much more on wxgrass and Cedrick did most of the
updates to the TclTk one. So with that disclaimer...

This is certainly a nice interface (JMP stats uses it too). The issue is
that the autogenerated dialogs depend on the xml interface hints to create
their GUI. There would need to be some kind consistent hint in the module
code to prompt either gui to build and populate the correct kind of widgets

>From my look at the xml generated by v.type, it doesn't seem to do a very
good job at this currently, resulting in a minimally functional
autogenerated dialog. Maybe there are hints there that I'm not
understanding. But it looks like we could do with better interface hints
with this module (at least having values as acceptable type pairs rather
than as single types would make it easier) and then finding a way to
transform them into a better interface.

That said, are there other modules that could benefit from the same kind of
interface, or is this the only one? I can't think of any, but it's still
early and there are 300+ modules.
