  41 wxDllWidget can be used to embed a wxWindow implemented in C++ in your
  42 wxPython application without the need to write a SWIG interface. Widget's code
  43 is stored in shared library or DLL that exports DLL_WidgetFactory symbol
  44 and loaded at runtime. All you have to do is to pass the name of DLL and the class
  45 to create to wxDllWidget's ctor.
  46
  47 Runtime-loadable widget must have HandleCommand method (see the example) that is
  48 used to communicate with Python app. You call wxDllWidget.SendCommand(cmd,param) from
  49 Python and it in turn calls HandleCommand of the loaded widget.
  50
  51 You must use DECLARE_DLL_WIDGET, BEGIN_WIDGET_LIBRARY, END_WIDGET_LIBRARY and
  52 REGISTER_WIDGET macros in your C++ module in order to provide all the meat
  53 wxDllWidget needs.
  54
  55 Example of use:
  56
  57     #define CMD_MAKEWHITE     1
  58
  59     class MyWindow : public wxWindow
  60     {
  61     public:
  62         MyWindow(wxWindow *parent, long style)
  63             : wxWindow(parent, -1) {}
  64
  65         int HandleCommand(int cmd, const wxString& param)
  66         {
  67             if (cmd == CMD_MAKEWHITE)
  68                 SetBackgroundColour(*wxWHITE);
  69             return 0;
  70         }
  71     };
  72     DECLARE_DLL_WIDGET(MyWindow)
  73
  74     class MyCanvasWindow : public wxScrolledWindow
  75     {
  76         ...
  77     };
  78     DECLARE_DLL_WIDGET(MyCanvasWindow)
  79
  80     BEGIN_WIDGET_LIBRARY()
  81         REGISTER_WIDGET(MyWindow)
  82         REGISTER_WIDGET(MyCanvasWindow)
  83     END_WIDGET_LIBRARY()
