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：
