Problem inserting Pygames on a wxPython panel using Boa Constructor

Question

Hello, im new in Python so im hoping to to get some help to figure out what is going wrong.

Im trying to run a Pygames from within wxPython panel (made on Boa Constructor). To do that i followed the instructions on the http://wiki.wxpython.org/IntegratingPyGame but still it isn't working.

Here is the Panel code that was used to make the integration:

class PG_panel(wx.Panel):

def __init__(self, ID, name, parent, mypos, mysize):
    # pygame is imported in this class
    # make it globally available
    global pygame
    #self.Fit()
    wx.Panel.__init__(self, id=wxID_FRMMAINPANELTABULEIRO, name='panelTabuleiro', parent=self, pos=(16, 96), size=mysize)
    # pygame uses SDL, set the environment variables
    os.environ['SDL_WINDOWID'] = str(self.GetHandle())
    os.environ['SDL_VIDEODRIVER'] = 'windib'

    # do the pygame stuff after setting the environment variables
    import pygame
    pygame.display.init()
    # create the pygame window/screen
    screen = pygame.display.set_mode(464, 464) #(424,450)
    # start the thread instance
    self.thread = PG_thread(screen)
    self.thread.start()

def __del__(self):
    self.thread.stop()

And im trying to use that panel on an interface from Boa Constructor, here is the code:

class frmMain(wx.Frame):

 def _init_ctrls(self, prnt):

    # generated method, don't edit

    wx.Frame.__init__(self, id=wxID_FRMMAIN, name='frmMain', parent=prnt,
          pos=wx.Point(660, 239), size=wx.Size(815, 661),
          style=wx.DEFAULT_FRAME_STYLE, title='Grupo 1 - Jogo de Damas')
    self._init_utils()
    self.SetClientSize(wx.Size(799, 623))
    self.SetBackgroundColour(wx.Colour(225, 225, 225))
    self.SetMinSize(wx.Size(784, 650))
    self.Center(wx.BOTH)
    self.SetMenuBar(self.menuBar1)
    #here begins my code
    mysize = (464, 464)
    mypos = (16, 96)        
    self.panelTabuleiro = PG_panel(wxID_FRMMAINPANELTABULEIRO, 'panelTabuleiro', self, mypos, mysize)

The original that was auto-made by the Boa Constructor is the following:

    self.panelTabuleiro = wx.Panel(id=wxID_FRMMAINPANELTABULEIRO,
          name='panelTabuleiro', parent=self, pos=wx.Point(16, 96),
          size=wx.Size(464, 464), style=wx.TAB_TRAVERSAL)
    self.panelTabuleiro.SetBackgroundColour(wx.Colour(232, 249, 240))
    self.panelTabuleiro.SetThemeEnabled(True)
    self.panelTabuleiro.SetHelpText('Tabuleiro')

The error that it gives is: Type error: in method 'new_Panel', expected argument 1 of type 'wxWindow*1 Exception AttributeError: "'PG_panel' object has no attribute 'thread' in > ignored

Any thoughts ? I appreciate any help. Thank you.
