如何整合 Pygame 和 PyQt4? [英] How to integrate Pygame and PyQt4?

问题描述

我使用的是 python 2.7 和 Ubuntu 14.04.

I'm using python 2.7 and Ubuntu 14.04.

我正在尝试做这个为了让我的 pygame 窗口在我的 GUI 中

I'm trying to do this in order to have my pygame window inside my GUI

在某些平台上，可以将 pygame 显示嵌入到已经存在的窗口中.为此，必须将环境变量 SDL_WINDOWID 设置为包含窗口 ID 或句柄的字符串.pygame显示初始化时检查环境变量

所以这就是我所做的:

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_())

但它不起作用.它只显示我的 PyQt 窗口.不知道是我做错了什么还是pygame无法与PyQt集成

But it doesn't work. It only shows my PyQt window. I don't know whether I'm doing something wrong or pygame just cannot be integrated with PyQt

我应该怎么做才能将我的 pygame 窗口嵌入到 frmMain 中?

What should I do to get my pygame window embedded in frmMain?

提前致谢.

推荐答案

根据上面的评论，这是一个示例解决方案:

Here is a sample solution as per the comment above:

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_()
