这是主程序

from ui_question import Ui_MainWindow

from PyQt4 import QtGui

from PyQt4.QtCore import QCoreApplication

from PyQt4.QtCore import *

import os,sys,subprocess,re

from ui_qtable import Ui_MainTable

class myui(QtGui.QMainWindow,Ui_MainWindow,Ui_MainTable):

def __init__(self, MainWindow):

# QtGui.QMainWindow.__init__(self)

super(my2d,self).__init__()

self.setupUi(MainWindow)

self.pushButton.clicked.connect(self.createMaterialFunc)

def createMaterialFunc(self):

print 'OK'

self.another = Ui_MainTable()

self.another.show()

if __name__ == "__main__":

import sys

app = QtGui.QApplication(sys.argv)

MainWindow = QtGui.QMainWindow()

ui = myui(MainWindow)

MainWindow.show()

sys.exit(app.exec_())

运行结果如下：

非常感谢大家！！麻烦大家了！！
