-<h2>Original Object Return</h2>
-
-<p>Several methods in wxWindows return pointers to base class objects,
-when in fact the actual object pointed to is of a derived type. Since
-SWIG isn't able to tell the actual type it just creates a new Python
-shadow object of the base type to wrap around the base type pointer
-and returns it.
-
-<p>In wxPython prior to 2.3.0 this could cause annoying issues. For
-example if you called:
-
-<pre>
-
- myText = someWindow.FindWindowById(txtID)
-</pre>
-
-expecting to get a wxTextCtrl you would actually get a wxWindow object
-instead. If you then try to call SetValue on that object you'll get
-an exception since there is no such method. This is the reason for
-the wxPyTypeCast hack that has been in wxPython for so long.
-
-<p>Even with wxPyTypeCast there was the issue that the object returned
-was not the same one that was created in Python originally, but a new
-object of the same type that wraps the same C++ pointer. If the
-programmer has set additional attributes of that original object they
-will not exist in the new object.
-
-<p>For a long time now I have wanted to do away with wxPyTypeCast and
-also find a way to return the original Python object from methods like
-FindWindowById. This project naturally divides into two phases:
-
-<p><ol>
-
-<li>Teach the wrapper methods how to return objects of the right type,
-and be able to then turn wxPyTypeCast in to a no-op.
-
-<li>Be able to return the original Python shadow object if it still exists.
-
-</ol>
-
-<p>The first button below shows the first of these phases (<i>working</i>)
-and the second will show #2 (<i>working as of Python 2.3.2</i>)
