消息对话框即我们平时说的Messagebox，看看它的原型，下面是wxWidgets中的原型定义，C++风格，与python风格的区别就是wx前缀与后面名称直接相连，例如wxMessageDialog，在wxpython中使用时就是wx.MessageDialog  wxMessageDialog([wxWindow](http://www.cnblogs.com/dyx1024/admin/)* parent, const [wxString](http://www.cnblogs.com/dyx1024/admin/)& message, const [wxString](http://www.cnblogs.com/dyx1024/admin/)& caption = "Message box", long style = wxOK | wxCANCEL, const [wxPoint](http://www.cnblogs.com/dyx1024/admin/)& pos = wxDefaultPosition) 其各参数不多做介绍，主要看看ShowModal()方法，它使用应用程序在对话框关闭前不能响应其它窗口的用户事件，返回一个整数，取值如下： wx.ID_YES, wx.ID_NO, wx.ID_CANCEL, wx.ID_OK。 另外，style的取值主要有以下几种： | wxOK | Show an OK button. | |-----|-----| | wxCANCEL | Show a Cancel button. | | wxYES_NO | Show Yes and No buttons. | | wxYES_DEFAULT | Used with wxYES_NO, makes Yes button the default - which is the default behaviour. | | wxNO_DEFAULT | Used with wxYES_NO, makes No button the default. | | wxICON_EXCLAMATION | Shows an exclamation mark icon. | | wxICON_HAND | Shows an error icon. | | wxICON_ERROR | Shows an error icon - the same as wxICON_HAND. | | wxICON_QUESTION | Shows a question mark icon. | | wxICON_INFORMATION | Shows an information (i) icon. | | wxSTAY_ON_TOP | The message box stays on top of all other window, even those of the other applications (Windows only).  | 还是看一个例子： 代码： ~~~ #!/usr/bin/env python # -*- coding: utf-8 -*- import wx class MyFrame(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, u'测试面板Panel', size = (600, 300)) #创建面板 panel = wx.Panel(self) #在Panel上添加Button button = wx.Button(panel, label = u'关闭', pos = (150, 60), size = (100, 60)) #绑定单击事件 self.Bind(wx.EVT_BUTTON, self.OnCloseMe, button) def OnCloseMe(self, event): dlg = wx.MessageDialog(None, u"消息对话框测试", u"标题信息", wx.YES_NO | wx.ICON_QUESTION) if dlg.ShowModal() == wx.ID_YES: self.Close(True) dlg.Destroy() if __name__ == '__main__': app = wx.PySimpleApp() frame = MyFrame(parent = None, id = -1) frame.Show() app.MainLoop() ~~~ 测试：
