pyqt4 - Python QtGui Push Button linked to setItem -

i new pyqt4. trying link button setitem in table. below have far.

from pyqt4 import qtcore, qtgui  try:     _fromutf8 = qtcore.qstring.fromutf8 except attributeerror:     def _fromutf8(s):         return s  try:     _encoding = qtgui.qapplication.unicodeutf8     def _translate(context, text, disambig):         return qtgui.qapplication.translate(context, text, disambig, _encoding) except attributeerror:     def _translate(context, text, disambig):         return qtgui.qapplication.translate(context, text, disambig)  class ui_form(object):     def setupui(self, form):         form.setobjectname(_fromutf8("form"))         form.resize(400, 300)         self.tablewidget = qtgui.qtablewidget(form)         self.tablewidget.setgeometry(qtcore.qrect(0, 0, 256, 192))         self.tablewidget.setobjectname(_fromutf8("tablewidget"))         self.tablewidget.setcolumncount(3)         self.tablewidget.setrowcount(3)         self.pushbutton = qtgui.qpushbutton(form)         self.pushbutton.setgeometry(qtcore.qrect(90, 230, 75, 23))         self.pushbutton.setobjectname(_fromutf8("pushbutton"))                     qtcore.qobject.connect(self.pushbutton, qtcore.signal(_fromutf8("clicked()")), self.tablewidget.setitem(0,0,qtgui.qtablewidgetitem("test")))         self.retranslateui(form)         qtcore.qmetaobject.connectslotsbyname(form)      def retranslateui(self, form):         form.setwindowtitle(_translate("form", "form", none))         self.pushbutton.settext(_translate("form", "clear", none))   if __name__ == "__main__":     import sys     app = qtgui.qapplication(sys.argv)     form = qtgui.qwidget()     ui = ui_form()     ui.setupui(form)     form.show()     sys.exit(app.exec_()) 

i error pretty long ( below ). there better way link button desire results want.

traceback (most recent call last):   file "c:\python27\lib\site-packages\pyqt4\test_scripts\ag_test.py", line 57, in <module>     ui.setupui(form)   file "c:\python27\lib\site-packages\pyqt4\test_scripts\ag_test.py", line 40, in setupui     qtcore.qobject.connect(self.pushbutton, qtcore.signal(_fromutf8("clicked()")), self.tablewidget.setitem(0,0,qtgui.qtablewidgetitem("adam"))) typeerror: arguments did not match overloaded call:   qobject.connect(qobject, signal(), qobject, slot(), qt.connectiontype=qt.autoconnection): argument 3 has unexpected type 'nonetype'   qobject.connect(qobject, signal(), callable, qt.connectiontype=qt.autoconnection): argument 3 has unexpected type 'nonetype'   qobject.connect(qobject, signal(), slot(), qt.connectiontype=qt.autoconnection): argument 2 has unexpected type 'str' 

another solution:

def setupui(self, form):   ...   self.pushbutton.clicked.connect(self.settablewidgetitem)  def settablewidgetitem(self):   self.tablewidget.setitem(0,0,qtgui.qtablewidgetitem("test"))
