In your python module, put this close to the top:
typedef struct {
PyObject_HEAD
GdkWindow *obj;
} PyGdkWindow_Object;
static PyTypeObject *PyGdkWindow_Type;
#define PyGdkWindow_Check(op) ((op)->ob_type == PyGdkWindow_Type)
#define PyGdkWindow_Get(op) (((PyGdkWindow_Object *)(op))->obj)
Now in your init function for the module, add code like this:
m = PyImport_ImportModule("_gtk");
d = PyModule_GetDict(m);
Py_DECREF(m);
PyGdkWindow_Type = (PyTypeObject *)PyDict_GetItemString(d,"GdkWindowType");
Py_INCREF(PyGdkWindow_Type);
Now in your functions, put something like this:
PyObject *py_win;
GdkWindow *win;
if (!PyArg_ParseTuple(args, "O!:some-func", PyGdkWindow_Type, &py_win))
return NULL;
win = PyGdkWindow_Get(py_win);
And that should do it. Now you know that you are getting a GdkWindow
passed to you, which you wouldn't know if it was passed as a CObject.
