問題描述

請教一下大家，想實現(xiàn)在主窗口中點擊按鈕調(diào)用一個新窗口，這個窗口是tablewidget，目前可以實現(xiàn)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。這是主窗口代碼

這是被調(diào)用的窗口代碼

這是主程序

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_())

運行結(jié)果如下：非常感謝大家！！麻煩大家了！！

問題解答

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

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