Question

我正在使用PyQT5，并且我想在TabWidget内运行一个外部窗口，类似to that，但是此示例仅适用于Windows，并且我想在linux（Ubuntu 14.04）操作系统中运行。我在此thread中也发现了类似的问题，但是答案没有用。还尝试了解决方法here，但也没有用。可以嵌入一个终端，例如this code，但是我不知道如何使用RViz命令执行同样的操作。我下面有一些代码，他使用 wmctrl 来选择RViz（我想嵌入到GUI中的应用程序）窗口ID，然后尝试将其放入“ fromWinID（）”类，但是窗口在我的应用程序外部打开，并收到错误消息：

QXcbConnection: XCB error: 3 (BadWindow), sequence: 415, resource id: -1222189812, major code: 7 (ReparentWindow), minor code: 0
QXcbConnection: XCB error: 3 (BadWindow), sequence: 460, resource id: -1222189812, major code: 7 (ReparentWindow), minor code: 0
QXcbConnection: XCB error: 3 (BadWindow), sequence: 461, resource id: -1222189812, major code: 8 (MapWindow), minor code: 0
QXcbConnection: XCB error: 3 (BadWindow), sequence: 463, resource id: -1222189812, major code: 18 (ChangeProperty), minor code: 0
QXcbConnection: XCB error: 3 (BadWindow), sequence: 464, resource id: -1222189812, major code: 12 (ConfigureWindow), minor code: 0

有人可以帮忙吗？

app = QtWidgets.QApplication(sys.argv)
