python和pyqt实现360的CLable控件

  代码如下:
 #!/usr/bin/python 
#-*-coding:utf-8-*-

from PyQt4.QtGui import *
from PyQt4.QtCore import *
from PyQt4.Qt import *

class CLabel(QWidget):

 signalLabelPress = pyqtSignal()

  #pointer members

  #self.m_pLabelIcon = QLabel(self)
  #self.m_pLabelText = QLabel(self)

 def setPixmap(self,pixmap):
  self.m_pLabelIcon.setPixmap(pixmap.scaled(QSize(30, 30), Qt.KeepAspectRatio, Qt.SmoothTransformation))
 

 def setText(self,text):
  self.m_pLabelText.setText(text)
 

 def setMouseEnterFlag(self, flag):
  self.m_mouseEnterFlag = flag
  self.update()

  self.m_mousePressFlag = flag
  self.update()

  self.setCursor(Qt.PointingHandCursor)
 

 def leaveEvent(self,event):
  self.setMouseEnterFlag(False)
 

 def mousePressEvent(self,e): 
  if(e.button() == Qt.LeftButton):  
   self.setMousePressFlag(True)
   self.signalLabelPress.emit()

   self.paintWidget(50, painter)  
  elif(self.getMousePressFlag()):  
   self.paintWidget(80, painter)  
  QWidget.paintEvent(self,e)
 

 def initVariable(self): 
  self.setMouseEnterFlag(False)
  self.setMousePressFlag(False)
 

 def initSetupUi(self): 
  self.createFrame()
  self.createWidget()
  self.createLayout()
 

 def createFrame(self): 
  self.setStyleSheet("QWidget background:transparentborder:0pxcolor:whitefont-weight:boldfont-size:16px")
 

 def createWidget(self):

  self.m_pHLayout = QHBoxLayout()
  self.m_pHLayout.setSpacing(10)
  self.m_pHLayout.setContentsMargins(QMargins(5, 0, 5, 0))
  self.m_pHLayout.addWidget(self.m_pLabelIcon)
  self.m_pHLayout.addWidget(self.m_pLabelText)
  self.m_pHLayout.addStretch()

  self.setLayout(self.m_pHLayout)
