例三：

主要是模仿了qt自带的clock例子，然后 通过 python的语法 进行实现，
同时添加了秒针 的实现
用到的工具 有qt 4.8；python 2.7 ;pyqt

import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
class clock (QWidget):
  def __init__(self):
    QWidget.__init__(self,windowTitle="python clock")
    timer = QTimer(self)
    self.connect(timer, SIGNAL("timeout()"),self,SLOT("update()"))
    timer.start(1000)
    self.resize(200,200)
  def paintEvent(self,e):
    hourColorHand = QPolygon([QPoint(7,8),QPoint(-7,8),QPoint(0,-30)])
    minuteColorHand = QPolygon([QPoint(7,8),QPoint(-7,8),QPoint(0,-70)])
    secondColorHand = QPolygon([QPoint(3,8),QPoint(-3,8),QPoint(0,-90)])
    hourColor = QColor(127,0,127)
    minuteColor = QColor(0,127,127,191)
    secondColor = QColor(0,100,100,100)
    painter = QPainter(self);
    side = min(self.width(),self.height())
    atime =QTime.currentTime()
    painter.setRenderHint(QPainter.Antialiasing)
    painter.translate(self.width()/2,self.height()/2)
    painter.scale(side/200,side/200)
    painter.setPen(Qt.NoPen)
    painter.setBrush(hourColor)
    painter.save()
    painter.rotate(30.0*(atime.hour() + atime.minute()/60.0))
    painter.drawConvexPolygon(hourColorHand)
    painter.restore()
    painter.setPen(hourColor)
    for i in range(0,12):
     painter.drawLine(88,0,96,0)
     painter.rotate(30.0)
    painter.setPen(Qt.NoPen)
    painter.setBrush(minuteColor)
    painter.save()
    painter.rotate(6.0*(atime.minute()+atime.second()/60.0))
    painter.drawConvexPolygon(minuteColorHand)
    painter.restore()
    painter.setPen(minuteColor)
    for i in range(0,60) :
     if (i%5)!=0 :
       painter.drawLine(92,0,96,0)
     painter.rotate(6.0)
    painter.setPen(Qt.NoPen)
    painter.setBrush(secondColor)
    painter.save()
    painter.rotate(6.0 * atime.second())
    painter.drawConvexPolygon(secondColorHand)
    painter.restore()
if __name__ == "__main__" :
   q = QApplication(sys.argv)
   s = clock()
   s.show()
   q.exec_()
