Abstract classes and RTTI

Hello,

I am unsure where to proceed when dealing with abstract classes, for
example, wxSizer.

In Window.cs, I haven't yet implemented Window::Sizer { get { ... } },
since wx::Sizer is abstract, it must use some sort of type information
to create the appropriate subclass.

The two possible ways to do this are as follows:

   1. Create a typemap as is done with wx::Event, and subclass each of
      the wxSizer subclasses, adding a method to grab some sort of type
      id.

   2. Use the C++ RTTI information to grab the type of each wxSizer
      subclass at runtime, then use this information to create a
      typemap.

Solution 1 seems like a hack, and I am rather unfamiliar with using RTTI
in solution 2.  I have no idea how cross-compiler/platform using RTTI
is;  for example, I believe that VS.NET requires additional settings to
be added in order to use RTTI.

Currently, I am just messing around with RTTI, and trying to store a
typemap in wx::Object, so that it can be used for other classes without
to much work.

Any suggestions for what I could try here?
