python+pyqt实现12306图片验证效果

本文实例为大家分享了python实现12306图片验证效果的具体代码,供大家参考,具体内容如下

思路:在鼠标点击位置加一个按钮,然后再按钮中的点击事件中写一个关闭事件.

#coding:utf-8

from PyQt4.QtGui import *

from PyQt4.QtCore import *

from push_button import *

from PIL import Image

class Yanzheng(QWidget):

def __init__(self,parent=None):

super(Yanzheng,self).__init__(parent)

self.m_start_point=0 #x坐标

self.m_end_point=0 #y坐标

self.coordinate=[]

self.codeimage="./img/code.png"

self.connect(self,SIGNAL("addlable"),self.addpic)

self.main_layout=QFormLayout()

self.setLayout(self.main_layout)

self.resize(293,190)

self.pixmap=QPixmap("./img/cur.png")

def addpic(self):

print self.m_start_point,self.m_end_point

xpoint=self.m_start_point

ypoint=self.m_end_point-28

codepng2 = PushButton(self)

codepng2.loadPixmapreal('./img/cur.png')

codepng2.setGeometry(self.m_start_point,self.m_end_point,30,30)

codepng2.show()

#self.emit(SIGNAL("dellabel"),self.codepng2)

self.coordinate.append("%s,%s" %(xpoint,ypoint))

self.connect(codepng2,SIGNAL("clicked()"),lambda:self.dellabel(codepng2,xpoint,ypoint))

#self.update()

#删除标记

def dellabel(self,q,x,y):

print x,y

self.coordinate.remove("%s,%s" %(x,y))

q.close()

def mousePressEvent(self,event):

if (event.type()==QEvent.MouseButtonPress):

self.m_start_point = event.pos().x()-12

self.m_end_point= event.pos().y()-12

self.emit(SIGNAL("addlable"))

def paintEvent(self, event):

p = QPainter(self)

p.drawPixmap(0,0,QPixmap(self.codeimage))

if __name__=='__main__':

import sys

app=QApplication(sys.argv)

inputurl=Yanzheng()

inputurl.show()

sys.exit(app.exec_())

效果图:
