如何整合Pygame和PyQt4？

这是上述评论的示例解决方案：

from PyQt4 import QtGuiimport pygameimport sysclass ImageWidget(QtGui.QWidget):    def __init__(self,surface,parent=None):        super(ImageWidget,self).__init__(parent)        w=surface.get_width()        h=surface.get_height()        self.data=surface.get_buffer().raw        self.image=QtGui.QImage(self.data,w,h,QtGui.QImage.Format_RGB32)    def paintEvent(self,event):        qp=QtGui.QPainter()        qp.begin(self)        qp.drawImage(0,0,self.image)        qp.end()class MainWindow(QtGui.QMainWindow):    def __init__(self,surface,parent=None):        super(MainWindow,self).__init__(parent)        self.setCentralWidget(ImageWidget(surface))pygame.init()s=pygame.Surface((640,480))s.fill((64,128,192,224))pygame.draw.circle(s,(255,255,255,255),(100,100),50)app=QtGui.QApplication(sys.argv)w=MainWindow(s)w.show()app.exec_()
