// This is an ugly hack to allow the use of Bind() instead of Connect() inside
// the library code if the library was built with support for it, here is how
// it is used:
//
// class SomeEventHandlingClass : wxBIND_OR_CONNECT_HACK_BASE_CLASS
//                                public SomeBaseClass
// {
// public:
//     SomeEventHandlingClass(wxWindow *win)
//     {
//         // connect to the event for the given window
//         wxBIND_OR_CONNECT_HACK(win, wxEVT_SOMETHING, wxSomeEventHandler,
//                                SomeEventHandlingClass::OnSomeEvent, this);
//     }
//
// private:
//     void OnSomeEvent(wxSomeEvent&) { ... }
// };
//
// This is *not* meant to be used by library users, it is only defined here
// (and not in a private header) because the base class must be visible from
// other public headers, please do NOT use this in your code, it will be
// removed from future wx versions without warning.
