請教一下大家,想實現在主窗口中點擊按鈕調用一個新窗口,這個窗口是tablewidget,目前可以實現彈出窗口,但是無法顯示表格,只有一個空白窗口。實在找不到原因了,還請大家指點。
這是主視窗程式碼

這是主程式

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_())

主程式line 17的createMaterialFunc()函數,改為如下:

    def createMaterialFunc(self):
        self.another = Ui_MainTable()
        self.table = QtGui.QMainWindow()
        self.another.setupUi(self.table)
        self.table.show()
