        #Bouton Option
        bmpOption = wx.Bitmap('btn_option.png',wx.BITMAP_TYPE_PNG)
        self.btnOption = buttons.GenBitmapButton(self, -1, bmpOption, pos = (2,24),size= (18,18), style=wx.BORDER_NONE)
        self.btnOption.SetToolTipString("Options")

    def MenuOptions(self):
        print "aa"
 
class MyApp(wx.App):
    def OnInit(self):
        fen = FenetrePrincipal(None, -1, "aaaa")

I found a solution so when i click on the menu for the first time nothing happen and after it work...

import wx
import wx.lib.buttons as buttons
 
class FenetrePrincipal(wx.Frame):
    def __init__(self, parent, ID, title):
        wx.Frame.__init__(self, parent, ID, title, wx.DefaultPosition, wx.Size(482, 68), style= wx.FRAME_NO_TASKBAR | wx.STAY_ON_TOP )
 
        #Bouton Option
        bmpOption = wx.Bitmap('btn_option.png',wx.BITMAP_TYPE_PNG)
        self.btnOption = buttons.GenBitmapButton(self, -1, bmpOption, pos = (2,24),size= (18,18), style=wx.BORDER_NONE)
        self.btnOption.SetToolTipString("Options")
        self.Bind(wx.EVT_BUTTON, self.OnOption, self.btnOption)
 
 
    def OnOption(self,event):
        menu= wx.Menu()
        menu.Append(101, "Options")
        self.PopupMenu(menu)
 
class MyApp(wx.App):
    def OnInit(self):
        fen = FenetrePrincipal(None, -1, "aaaa")
        fen.Show(True)
        self.SetTopWindow(fen)
        return True
 
app = MyApp()
app.MainLoop()

Create the menu early and keep a reference to it:

import wx
import wx.lib.buttons as buttons
 
class FenetrePrincipal(wx.Frame):
    def __init__(self, parent, ID, title):
        wx.Frame.__init__(self, parent, ID, title, wx.DefaultPosition, wx.Size(482, 68), style= wx.FRAME_NO_TASKBAR | wx.STAY_ON_TOP )
 
        #Bouton Option
##        bmpOption = wx.Bitmap('btn_option.png',wx.BITMAP_TYPE_PNG)
##        self.btnOption = buttons.GenBitmapButton(self, -1, bmpOption, pos = (2,24),size= (18,18), style=wx.BORDER_NONE)
        self.btnOption = wx.Button(self, -1, pos=(2,24), size=(18,18), style=wx.BORDER_NONE)
        self.btnOption.SetToolTipString("Options")
        self.Bind(wx.EVT_BUTTON, self.OnOption, self.btnOption)
        menu= wx.Menu()
        menu.Append(101, "Options")
        self.myMenu = menu
 
 
    def OnOption(self,event):
        self.PopupMenu(self.myMenu)
 
class MyApp(wx.App):
    def OnInit(self):
        fen = FenetrePrincipal(None, -1, "aaaa")
        fen.Show(True)
        self.SetTopWindow(fen)
        return True
 
app = MyApp()
app.MainLoop()
