import urllib import http.cookiejar import time import sys bs4 import beautifulsoup pyqt4 import qtgui pyqt4 import qtcore   class baidumainwindow(qtgui.qmainwindow):     def __init__(self, parent=none):         super(baidumainwindow, self).__init__(parent)         self.initui()      def initui(self):         self.centralwidget = baiduwidget(self)         self.setcentralwidget(self.centralwidget)         self.resize(600, 400)         self.move(qtgui.qapplication.desktop().screen().rect().center() - self.rect().center())         self.statusbar().showmessage('ready')   class baiduwidget(qtgui.qwidget):     def __init__(self, parent):         super(baiduwidget, self).__init__(parent)         self.initui()      def initui(self):         lb = qtgui.qlabel('search word')         self.keywordedit = qtgui.qlineedit()         self.okbutton = qtgui.qpushbutton('search')         self.containfilter = qtgui.qlineedit()         self.exceptfilter = qtgui.qlineedit()         self.result = qtgui.qtextbrowser()          spaceritem = qtgui.qspaceritem(30, 50)          grid = qtgui.qgridlayout()         grid.setspacing(10)         grid.additem(spaceritem, 0, 0)         grid.addwidget(lb, 1, 0)         grid.addwidget(self.keywordedit, 2, 0)         grid.addwidget(self.okbutton, 5, 0)         grid.additem(spaceritem, 7, 0)         grid.addwidget(self.result, 0, 1, 8, 1)         grid.setcolumnstretch(1, 4)         self.setlayout(grid)    if __name__ == '__main__':     app = qtgui.qapplication(sys.argv)     form = baidumainwindow()     form.show()     sys.exit(app.exec_()) 

the problem is: spaceritem has beed added grid twice. object freed twice qt when exited program.

     def initui(self):         lb = qtgui.qlabel('search word')         self.keywordedit = qtgui.qlineedit()         self.okbutton = qtgui.qpushbutton('search')         self.containfilter = qtgui.qlineedit()         self.exceptfilter = qtgui.qlineedit()         self.result = qtgui.qtextbrowser()          spaceritem = qtgui.qspaceritem(30, 50)          grid = qtgui.qgridlayout()         grid.setspacing(10)         grid.additem(spaceritem, 0, 0)         grid.addwidget(lb, 1, 0)         grid.addwidget(self.keywordedit, 2, 0)         grid.addwidget(self.okbutton, 5, 0)         grid.additem(spaceritem, 7, 0)         grid.addwidget(self.result, 0, 1, 8, 1)         grid.setcolumnstretch(1, 4)         self.setlayout(grid)  

you should use 2 qspaceritems.

     def initui(self):         lb = qtgui.qlabel('search word')         self.keywordedit = qtgui.qlineedit()         self.okbutton = qtgui.qpushbutton('search')         self.containfilter = qtgui.qlineedit()         self.exceptfilter = qtgui.qlineedit()         self.result = qtgui.qtextbrowser()          spaceritem = qtgui.qspaceritem(30, 50)         spaceritem2 = qtgui.qspaceritem(30, 50)          grid = qtgui.qgridlayout()         grid.setspacing(10)         grid.additem(spaceritem, 0, 0)         grid.addwidget(lb, 1, 0)         grid.addwidget(self.keywordedit, 2, 0)         grid.addwidget(self.okbutton, 5, 0)         grid.additem(spaceritem2, 7, 0)         grid.addwidget(self.result, 0, 1, 8, 1)         grid.setcolumnstretch(1, 4)         self.setlayout(grid)
