Dotaz: PyGTK - win DLL gtkIEembed + ctypes

[pq]

Zdravim, potrebuji na win platforme vnorit do GUI okno internet exploreru pomoci PyGTK. Nasel jsem existujici DLL knihovnu GtkIEEmbed (http://live.gnome.org/GtkIEEmbed), ktera by mela pomoci funkce gtk_ie_embed_new() vytvorit objekt typu gtk.Widget. Volam tuto funkci pres ctypes (nemam s ni zatim zadne zkusenosti), ale nefunguje mi to - funkce vraci jen hodnotu INT, nedari se mi ji zmenit ani pomoci restype... Budu velmi vdecny za nejake nakopnuti...

Prozatim experimentuju s timhle:

import gtk
from ctypes import *

class TinyIE:
    def __init__(self):

        self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)

        gtkie = cdll.LoadLibrary("libgtkieembed-0.dll")
        gtkie.gtk_ie_embed_new.restype = gtk.Widget
        self.ie = gtkie.gtk_ie_embed_new()

        self.window.add(self.ie)
        self.window.show_all()

if __name__ == '__main__':
  TinyIE()
  gtk.main()

Člověk musí napřed položit dotaz, aby pak konečně o něco zakopl na webu :))

Funkční kód:

import ctypes
from ctypes import *
import gtk
import gobject

class _PyGObject_Functions(ctypes.Structure):
 _fields_ = [
 ('register_class',
 ctypes.PYFUNCTYPE(ctypes.c_void_p, ctypes.c_char_p,
 ctypes.c_int, ctypes.py_object,
 ctypes.py_object)),
 ('register_wrapper',
 ctypes.PYFUNCTYPE(ctypes.c_void_p, ctypes.py_object)),
 ('register_sinkfunc',
 ctypes.PYFUNCTYPE(ctypes.py_object, ctypes.c_void_p)),
 ('lookupclass',
 ctypes.PYFUNCTYPE(ctypes.py_object, ctypes.c_int)),
 ('newgobj',
 ctypes.PYFUNCTYPE(ctypes.py_object, ctypes.c_void_p)),
 ]


class PyGObjectCAPI(object):
 def __init__(self):
 addr = ctypes.pythonapi.PyCObject_AsVoidPtr(
 ctypes.py_object(gobject._PyGObject_API))
 self._api = _PyGObject_Functions.from_address(addr)

 def pygobject_new(self, addr):
 return self._api.newgobj(addr)


class TinyIE:
 def __init__(self):

 self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)

 gtkie = CDLL("libgtkieembed-0.dll")
 capi = PyGObjectCAPI()
 self.ie = capi.pygobject_new(gtkie.gtk_ie_embed_new())
 
 self.window.add(self.ie)
 self.window.show_all()
 
 contents = "<html><title>Hello world / html verze.</title><body><P><B>Hello</B> <i>world</i> <font color='red'>!</font></body></html>";
 gtkie.gtk_ie_embed_load_html_from_string (hash(self.ie), contents);
 

if __name__ == '__main__':
 TinyIE()
 gtk.main()
