java - 将自定义组件添加到 NetBeans GUI 构建器! (世界风)

Question

好的，我正在尝试将来自 NASA 的 World Wind globe 添加到 NetBeans GUI 构建器创建的 GUI 窗口中。我的示例代码实例化了它自己的窗口，GUI 构建器希望我不要编辑将其插入的必要区域 :) 我会自己编写，但这是 NetBeans 平台应用程序的一部分，包含代码和注释我还没有准备好处理呢。我不确定如何完成此操作。这是我希望在窗口中显示的示例代码:

public class WorldWindTest {

public static void main(String[] args) {

    //create a WorldWind main object
    WorldWindowGLCanvas worldWindCanvas = new WorldWindowGLCanvas();
    worldWindCanvas.setModel(new BasicModel());
            Position myPoint = Position.fromDegrees(31.12, -88.64, 35000);


    //build Java swing interface
    JFrame frame = new JFrame("World Wind");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(worldWindCanvas);
    frame.setSize(800,600);
    frame.setVisible(true);

    //create some "Position" to build a polyline
    LinkedList<Position> list = new LinkedList<Position>();

//          list.add(Position.fromDegrees(i,0.0,i*20000));
    }

            list.add(Position.fromDegrees(30.12, -85.64, 35000));
            list.add(Position.fromDegrees(31.12, -88.64, 35000));


    //create "Polyline" with list of "Position" and set color / thickness
    Polyline polyline = new Polyline(list);
    polyline.setColor(Color.RED);
    polyline.setLineWidth(3.0);

    //create a layer and add Polyline
    RenderableLayer layer = new RenderableLayer();
    layer.addRenderable(polyline);
    //add layer to WorldWind
    worldWindCanvas.getModel().getLayers().add(layer);
}
}

为了进一步阐述我的评论，我认为您可以创建一个名为 SetUpWorldWindowGLCanvas 的类，并在其中初始化并设置您的 WorldWindowGLCanvas 对象，然后为其提供一个公共(public) getter 方法，使您能够获取设置 WorldWindowGLCanvas 对象。即，

public class SetUpWorldWindowGLCanvas {

    WorldWindowGLCanvas worldWindCanvas = new WorldWindowGLCanvas();

    public SetUpWorldWindowGLCanvas() {
        worldWindCanvas.setModel(new BasicModel());
        Position myPoint = Position.fromDegrees(31.12, -88.64, 35000);

        // ... etc
    }

    public WorldWindowGLCanvas getWwGlCanvas() {
        return worldWindCanvas;
    }
}

然后将此 BorderLayout.CENTER 放入在您的 GUI 构建器中创建并使用 BorderLayout 作为其布局管理器的 JPanel 中。
