消息對話框即我們平時說的Messagebox，看看它的原型，下面是wxWidgets中的原型定義，C++風格，與python風格的區別就是wx前綴與后面名稱直接相連，例如wxMessageDialog，在wxpython中使用時就是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) 其各參數不多做介紹，主要看看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。 另外，style的取值主要有以下幾種： | 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).? | 還是看一個例子： 代碼： ~~~ #!/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'測試面板Panel', size = (600, 300)) #創建面板 panel = wx.Panel(self) #在Panel上添加Button button = wx.Button(panel, label = u'關閉', pos = (150, 60), size = (100, 60)) #綁定單擊事件 self.Bind(wx.EVT_BUTTON, self.OnCloseMe, button) def OnCloseMe(self, event): dlg = wx.MessageDialog(None, u"消息對話框測試", u"標題信息", 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() ~~~ 測試：
