from PyQt4 import QtGui,QtCore,Qt

from ti import Ui_Form

class Example(QtGui.QDialog,Ui_Form):

def __init__(self,parnet=None):

super(Example, self).__init__(parnet)

self.setupUi(self)

tim=QtCore.QTimer(self)

tim.timeout.connect(self.times1)

tim.timeout.connect(self.times2)

tim.start(1)

def times1(self):#第一种简单

a=datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')

self.lineEdit.setText(a)

def times2(self):#第二种

a=QtCore.QTime.currentTime()

a1=Qt.QDate.currentDate()

a2=a1.toString('yyyy-MM-dd')+' '+a.toString('hh:mm:ss')

self.lineEdit_2.setText(a2)

def main():

app = QtGui.QApplication(sys.argv)

ex = Example()

ex.show()

sys.exit(app.exec_())

main()

结果如下:
