如何集成Pygame和PyQt4？

Question

我使用的是Python2.7和Ubuntu14.04。

我正在尝试this以便将pygame窗口放在我的GUI中

On some platforms it is possible to embed the pygame display into an already existing window. To do this, the environment variable SDL_WINDOWID must be set to a string containing the window id or handle. The environment variable is checked when the pygame display is initialized

我就是这么做的：

from PyQt4 import QtGui, QtCore
import os
import subprocess
import sys

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
    MainWindow.setWindowModality(QtCore.Qt.ApplicationModal)
    MainWindow.setFixedSize(800, 600)
    QtCore.QMetaObject.connectSlotsByName(MainWindow)
    self.iniMap()

def iniMap(self):
    command = "xprop -root _NET_ACTIVE_WINDOW"
    output = subprocess.Popen(["/bin/bash", "-c", command], stdout=subprocess.PIPE)
    activeWindowID = str(output.communicate()[0].decode("utf-8").strip().split()[-1])
    os.environ['SDL_WINDOWID'] = activeWindowID
    import pygame
    pygame.init()
    screen = pygame.display.set_mode((565, 437), pygame.NOFRAME)

class frmMain(QtGui.QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(frmMain, self).__init__(parent, flags=QtCore.Qt.FramelessWindowHint)
        self.setAttribute(QtCore.Qt.WA_DeleteOnClose)
        self.setupUi(self)

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    form = frmMain()
    form.show()
    sys.exit(app.exec_())

但没用。它只显示我的PyQt窗口。我不知道我是做错了什么还是pygame不能与PyQt集成

我该怎么做才能让pygame窗口嵌入到frmMain？

提前谢谢你。
