pyqt4之QMessageBox用法

    # -*- coding: utf-8 -*-
import PyQt4, PyQt4.QtGui, sys 
import binascii    #导入数据转换包
import sys


from PyQt4 import QtGui, QtCore
from PyQt4.QtGui import QDialog
from PyQt4.QtCore import pyqtSignature

用法如下，记得对齐啊

QtGui.QMessageBox.about( self, 'PyQt', "About" )
r = QtGui.QMessageBox.question( self, "PyQt", "Question", QtGui.QMessageBox.Yes, QtGui.QMessageBox.No, QtGui.QMessageBox.Cancel )
