Question

我目前正在构建一个同时显示列表和图像的GUI，我也想同时显示当前周围环境的点云，并能够访问该GUI中的所有内容。

我尝试过VTK可视化工具，问题是渲染循环会阻塞其他所有内容，直到窗口关闭。

我目前正在尝试使用PyQtGraph的GLViewWidget，但无法将其插入所需的位置，并且无法处理GUI中的其他项目。

我必须将窗口指定为父窗口，才能看到窗口小部件。但是它跳到了窗口的左上角。

        self.w.addItem(layout)
        self.setUp_pen_types()
        self.qt_connections()

结果看起来像这样-尽管我想将渲染的3D场景（具有黑色背景色）放置在2D图像小部件下方。

在GraphicsWindow的特定位置插入GLViewWidget
