python - pyqt 调用tablewidget窗口时无法显示窗口内容

问题描述

请教一下大家，想实现在主窗口中点击按钮调用一个新窗口，这个窗口是tablewidget，目前可以实现弹出窗口，但是无法显示表格，只有一个空白窗口。实在找不到原因了，还请大家指点。这是主窗口代码

这是被调用的窗口代码

这是主程序

from ui_question import Ui_MainWindowfrom PyQt4 import QtGuifrom PyQt4.QtCore import QCoreApplicationfrom PyQt4.QtCore import * import os,sys,subprocess,refrom ui_qtable import Ui_MainTableclass 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！！

问题解答

主程序line 17的createMaterialFunc()函数，改为如下：

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

运行结果：
