两个关于SimpleUniverse的问题。。。

Question

我想将用来显示java3d object的视窗的title bar隐藏掉，同时给与全屏显示，请问要怎样做？一般的视窗是这样的：
 我想改变成这样：
 

Answer 1

frame.setUndecorated(true); // 禁用此窗体的装饰
frame.setExtendedState(JFrame.MAXIMIZED_BOTH); // 此状态位掩码指示将窗体完全最大化（水平和垂直方向）。frame.setVisual(true);

Answer 2

我试了一楼和二楼的方法还是不行不行我放上我的代码好了 大家请帮我看看public class Process 
{
public void build() 
{
try 
{
            BranchGroup bg = loadBranchGroup();
            SimpleUniverse u = new SimpleUniverse();
            u.getViewingPlatform().setNominalViewingTransform();
            u.addBranchGraph(bg);
        } catch (FileNotFoundException ex) 
        {
            Logger.getLogger(GameProcess.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

private BranchGroup loadBranchGroup() throws FileNotFoundException {
        Loader3DS dd = new Loader3DS();
        Scene scene = dd.load("747.3DS");
        System.out.println("scene=" + scene);
        if (scene != null) {            BranchGroup objRoot = new BranchGroup();
            BranchGroup bg = scene.getSceneGroup();
            TransformGroup objTrans = new TransformGroup();
            Transform3D trans=new Transform3D();
            trans.setScale(0.3f);
            objTrans.setTransform(trans);
            objTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
            objTrans.addChild(bg);            objRoot.addChild(objTrans);
            BoundingSphere bounds = new BoundingSphere(new Point3d(0.0, 0.0, 0.0), 100.0);
            MouseRotate behavior = new MouseRotate();
            behavior.setTransformGroup(objTrans);
            objTrans.addChild(behavior);
            behavior.setSchedulingBounds(bounds);            MouseTranslate tr = new MouseTranslate();
            tr.setTransformGroup(objTrans);
            objTrans.addChild(tr);
            tr.setSchedulingBounds(bounds);
            
            MouseWheelZoom tr1 = new MouseWheelZoom();
            tr1.setTransformGroup(objTrans);
            objTrans.addChild(tr1);
            tr1.setSchedulingBounds(bounds);
            Color3f light1Color = new Color3f(Color.RED);
            Vector3f light1Direction = new Vector3f(0f, 0f, -10f);
            DirectionalLight light1 = new DirectionalLight(light1Color, light1Direction);
            light1.setInfluencingBounds(bounds);
            objRoot.addChild(light1);
            return objRoot;
        }
        return null;
    }
