commandType=wx.wxEVT_COMMAND_BUTTON_CLICKED

看下面的演示代码，点击btn2会产生一个点击btn1的event：

import wx

class Frame(wx.Frame):
    def __init__(self, *a, **kw):
        super(Frame, self).__init__(*a, **kw)
        self.btn = b = wx.Button(self, -1, 'Click me!')
        b2 = wx.Button(self, -1, 'Click the above button by code!')
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.AddMany([b, b2])
        self.SetSizerAndFit(sizer)
        self.Bind(wx.EVT_BUTTON, self.on_btn, b)
        self.Bind(wx.EVT_BUTTON, self.on_btn2, b2)

    def on_btn(self, evt):
        wx.MessageBox('Clicked')

    def on_btn2(self, evt):
        new_event = wx.CommandEvent(wx.wxEVT_COMMAND_BUTTON_CLICKED,
               self.btn.GetId())
        wx.PostEvent(self, new_event)


if __name__ == '__main__':
    app = wx.PySimpleApp()
    frame = Frame(None, -1, 'Test')
    frame.Show()
    app.MainLoop()
