===== Gestire i menu da file xrc =====
La procedura è un po' diversa ma assomiglia a quella dei widgets:
<code python>
                #Getting menu
		self.menubar = self.frame.GetMenuBar()
		self.mnuItemExit = self.menubar.FindItemById(xrc.XRCID('mnuItemExit'))
		self.mnuItemNewProfile = self.menubar.FindItemById(xrc.XRCID('mnuItemNewProfile'))    
		#Bind event Menu
		self.frame.Bind(wx.EVT_MENU, self.quit, self.mnuItemExit)
		self.frame.Bind(wx.EVT_MENU, self.openProfiles, self.mnuItemNewProfile)

</code>



===== Freezare la nostra app =====
Usando cx_freeze possiamo usare il seguente script.

**make.py**
<code python>
import sys
from cx_Freeze import setup, Executable

# Dependencies are automatically detected, but it might need fine tuning.
build_exe_options = {"packages": ["os"], "excludes": ["tkinter"]}

# GUI applications require a different base on Windows (the default is for a
# console application).
base = None
if sys.platform == "win32":
    base = "Win32GUI"

setup(  name = "guifoo",
        version = "0.1",
        description = "My GUI application!",
        options = {"build_exe": build_exe_options},
        executables = [Executable("hello.py", base=base)])
