如何整合Pygame和PyQt4？

Question

我正在使用 python 2.7 和 Ubuntu 14.04。

我正在尝试 this 以便让我的 pygame window 进入我的 GUI

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

这就是我所做的：

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_())

但是没有用。它只显示我的 PyQt window。我不知道是我做错了什么还是 pygame 无法与 PyQt

集成

我应该怎么做才能让我的 pygame window 嵌入 frmMain？

提前致谢。

根据上面的评论，这是一个示例解决方案：

from PyQt4 import QtGui
import pygame
import sys

class 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_()
