wxMessageDialog(wxWindow* parent, const wxString& message, const wxString& caption = "Message box", long style = wxOK | wxCANCEL, const wxPoint& pos = wxDefaultPosition)

ShowModal()方法，它使用應用程序在對話框關閉前不能響應其它窗口的用戶事件，返回一個整數，取值如下：

wx.ID_YES, wx.ID_NO, wx.ID_CANCEL, wx.ID_OK。

style的取值主要有以下幾種：

#!/usr/bin/env python
