      self.SetTitle("Panel One Showing")

# Run the program 
if __name__ == "__main__": 
    app = wx.App(False) 
    frame = MyForm() 
    frame.Show() 
    app.MainLoop() 

更改面板我想打電話給我時，請在類PanelOne.This應用程序的按鈕，我想喜歡this code in Tkinter工作功能onSwitchPanels。

我有堆疊傢伙，幫助我，非常感謝。

我在一年前編寫了關於這個主題的教程，雖然我使用菜單來切換。你可以調整代碼來讓你的按鈕做到這一點。這裏的教程：http://www.blog.pythonlibrary.org/2010/06/16/wxpython-how-to-switch-between-panels/

編輯：上面的代碼的問題是三重。首先在onSwitchPanels方法中，您需要具有「self.panel_one.Hide（）」。請注意代碼中缺少的括號。其次，你真的需要「self.Layout（）」不縮進，所以它和if語句在同一層，而不在「else」部分。最後，你不能從PanelOne調用「onSwitchPanels」，因爲它沒有在那裏定義。所以它是這樣的，雖然你可以改變它：

button.Bind(wx.EVT_BUTTON, parent.onSwitchPanels) 

長得醜，而且並不推薦使用，但它的作品。不過，您應該使用PubSub。

編輯＃2：猜猜我應該剛剛發佈的代碼，因爲OP甚至不會嘗試我的建議。
