"""
Easy generation of new events classes and binder objects.
Description
===========
This module contains two functions which makes the generation of custom wxPython events
particularly easy.
Usage
=====
Sample usage::
import wx
import time
import threading
import wx.lib.newevent as NE
MooEvent, EVT_MOO = NE.NewEvent()
GooEvent, EVT_GOO = NE.NewCommandEvent()
DELAY = 0.7

ID_CMD2 = wx.NewIdRef()
class Frame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, "MOO")
sizer = wx.BoxSizer(wx.VERTICAL)
self.Bind(EVT_MOO, self.on_moo)
b = wx.Button(self, -1, "Generate MOO")
sizer.Add(b, 1, wx.EXPAND)
