Added wxDllWidget from Vaclav Slavik which allows wx widgets derived
from wxWindow to be loaded from a C++ .dll (or .so) and be used in a
wxPython program, without the widget having to be SWIGged first. The
visible API of the widget is limited to wxWindow methods plus a
SendCommand method, but it is still quite powerful. See
wxPython/contrib/dllwidget and wxPython/demo/dllwidget for more
details.

/*
wxDllWidget can be used to embed a wxWindow implemented in C++ in your
wxPython application without the need to write a SWIG interface. Widget's code
is stored in shared library or DLL that exports DLL_WidgetFactory symbol
and loaded at runtime. All you have to do is to pass the name of DLL and the class
to create to wxDllWidget's ctor.
Runtime-loadable widget must have HandleCommand method (see the example) that is
used to communicate with Python app. You call wxDllWidget.SendCommand(cmd,param) from
Python and it in turn calls HandleCommand of the loaded widget.
You must use DECLARE_DLL_WIDGET, BEGIN_WIDGET_LIBRARY, END_WIDGET_LIBRARY and
REGISTER_WIDGET macros in your C++ module in order to provide all the meat
wxDllWidget needs.
Example of use:
#define CMD_MAKEWHITE 1
class MyWindow : public wxWindow
{
public:
MyWindow(wxWindow *parent, long style)
: wxWindow(parent, -1) {}
int HandleCommand(int cmd, const wxString& param)
{
if (cmd == CMD_MAKEWHITE)
SetBackgroundColour(*wxWHITE);
return 0;
}
};
DECLARE_DLL_WIDGET(MyWindow)
class MyCanvasWindow : public wxScrolledWindow
{
...
};
DECLARE_DLL_WIDGET(MyCanvasWindow)
BEGIN_WIDGET_LIBRARY()
REGISTER_WIDGET(MyWindow)
REGISTER_WIDGET(MyCanvasWindow)
END_WIDGET_LIBRARY()

/*
wxDllWidget can be used to embed a wxWindow implemented in C++ in your
wxPython application without the need to write a SWIG interface. Widget's code
is stored in shared library or DLL that exports DLL_WidgetFactory symbol
and loaded at runtime. All you have to do is to pass the name of DLL and the class
to create to wxDllWidget's ctor.
Runtime-loadable widget must have HandleCommand method (see the example) that is
used to communicate with Python app. You call wxDllWidget.SendCommand(cmd,param) from
Python and it in turn calls HandleCommand of the loaded widget.
You must use DECLARE_DLL_WIDGET, BEGIN_WIDGET_LIBRARY, END_WIDGET_LIBRARY and
REGISTER_WIDGET macros in your C++ module in order to provide all the meat
wxDllWidget needs.
Example of use:
#define CMD_MAKEWHITE 1
class MyWindow : public wxWindow
{
public:
MyWindow(wxWindow *parent, long style)
: wxWindow(parent, -1) {}
int HandleCommand(int cmd, const wxString& param)
{
if (cmd == CMD_MAKEWHITE)
SetBackgroundColour(*wxWHITE);
return 0;
}
};
DECLARE_DLL_WIDGET(MyWindow)
class MyCanvasWindow : public wxScrolledWindow
{
...
};
DECLARE_DLL_WIDGET(MyCanvasWindow)
BEGIN_WIDGET_LIBRARY()
REGISTER_WIDGET(MyWindow)
REGISTER_WIDGET(MyCanvasWindow)
END_WIDGET_LIBRARY()
*/
