text in the demo for more details of what this means, but in a nutshell methods such as wxWindow.GetParent or FindWindowById will now return a shadow object of the proper type if it can. By "proper type" I mean that if the wxWindow pointer returned from FindWindowById really points to a wxButton then the Python object constructed will be of a wxButtonPtr class instead of wxWindowPtr as before. This should reduce or eliminiate the need for wxPyTypeCast. (Woo Hoo!) The objects returned are still not the original Python object, but that is the next step. (Although it will probably only work on Python 2.1 and beyond because it will use weak references.) A few other minor tweaks and fixes and additions for things found while doing the OOR stuff. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@10197 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
