Messagedialog小部件是一个Dialog窗口,配置为显示代表消息类型的图像,即错误,问题或某些参考文本。通过使用以下构造函数声明MessageDialog对象-
gtk.MessageDialog(parent = None, flags = 0, type = gtk.MESSAGE_INFO,
buttons = gtk.BUTTONS_NONE, message_format = None)
以下预定义的消息类型用于配置消息对话框-
gtk.MESSAGE_INFO | This is an informational message |
gtk.MESSAGE_WARNING | This is a nonfatal warning message |
gtk.MESSAGE_QUESTION | This question requires a choice |
gtk.MESSAGE_ERROR | This is a fatal error message |
也可以使用一组预定义的按钮集。
gtk.BUTTONS_NONE | No buttons at all |
gtk.BUTTONS_OK | This is an OK button |
gtk.BUTTONS_CLOSE | This is a Close button |
gtk.BUTTONS_CANCEL | This is a Cancel button |
gtk.BUTTONS_YES_NO | These are the Yes and No buttons |
gtk.BUTTONS_OK_CANCEL | These are OK and Cancel buttons |
激活MessageBox菜单项后,将调用以下回调函数,并弹出一个消息框作为输出。
def on_msgdlg(self, widget):
md = gtk.MessageDialog(self,
gtk.DIALOG_DESTROY_WITH_PARENT, gtk.MESSAGE_ERROR,
gtk.BUTTONS_CLOSE, "Error message")
md.run()
上面的函数将生成以下输出-
