JME 3 +鞦韆，多個畫布

Question

我與JME3玩和目前面臨如下問題：

當LWJGL畫布都包含在應用程序的多個選項卡，其中沒有或只有1運行。

下面是一個例子：

SwingCanvas.java：

package jme3test.helloworld; 

import java.awt.Dimension; 
import javax.swing.JFrame; 

import com.jme3.app.SimpleApplication; 
import com.jme3.material.Material; 
import com.jme3.math.ColorRGBA; 
import com.jme3.scene.Geometry; 
import com.jme3.scene.shape.Box; 
import com.jme3.system.AppSettings; 
import com.jme3.system.JmeCanvasContext; 

public class SwingCanvas extends SimpleApplication { 

    private void SwingCanvasTest() { 
     SwingCanvas app = new SwingCanvas(); 
     app.start(); 
    } 

    @Override 
    public void simpleInitApp() { 
     // activate windowed input behaviour 
     flyCam.setDragToRotate(true); 

     Box box = new Box(2, 2, 2); 
     Geometry geom = new Geometry("Box", box); 
     Material mat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md"); 
     mat.setColor("Color", ColorRGBA.Blue); 
     geom.setMaterial(mat); 

     rootNode.attachChild(geom); // make the cube appear in the scene 
    } 

    public JmeCanvasContext createJMEcanvas(){ 
     AppSettings settings = new AppSettings(true); 
     settings.setWidth(640); 
     settings.setHeight(480); 

     this.setSettings(settings); 
     this.createCanvas(); // create canvas! 

     JmeCanvasContext ctx = (JmeCanvasContext) this.getContext(); 
     ctx.setSystemListener(this); 
     Dimension dim = new Dimension(640, 480); 
     ctx.getCanvas().setPreferredSize(dim); 

     return ctx; 
    } 

    public static void main(String[] args) { 
     java.awt.EventQueue.invokeLater(new Runnable() { 
      public void run() { 

       SwingCanvas canvasApplication = new SwingCanvas(); 

       JFrame window = new JFrame("Swing Application"); 
       window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

       window.add(canvasApplication.createJMEcanvas().getCanvas()); 
       window.pack(); 
       window.setVisible(true); 

       canvasApplication.start();    
      } 
     }); 
    } 
} 

SwingApplicationJME.java：

package jme3test.helloworld; 

import java.awt.BorderLayout; 

import javax.swing.JButton; 
import javax.swing.JComponent; 
import javax.swing.JFrame; 
import javax.swing.JPanel; 
import javax.swing.JSplitPane; 
import javax.swing.JTabbedPane; 
import javax.swing.SwingUtilities; 

import com.jme3.system.JmeCanvasContext; 

public class SwingApplicationJME { 

    public SwingApplicationJME(){ 
     JFrame frame = new JFrame("JME Swing Application"); 
     frame.setSize(800, 600); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.add(getLayout()); 
     frame.setVisible(true); 
    } 

    private JComponent getLayout(){ 
     JTabbedPane tabbedPane = new JTabbedPane(); 

     SwingCanvas canvas1 = new SwingCanvas(); 
     SwingCanvas canvas2 = new SwingCanvas(); 
     SwingCanvas canvas3 = new SwingCanvas(); 

     JmeCanvasContext ctx1 = canvas1.createJMEcanvas(); 
     JmeCanvasContext ctx2 = canvas2.createJMEcanvas(); 
     JmeCanvasContext ctx3 = canvas3.createJMEcanvas(); 

     JPanel JME_panel_1 = new JPanel(new BorderLayout()); 
     JME_panel_1.add(new JButton("WEST"), BorderLayout.WEST); 
     JME_panel_1.add(new JButton("NORTH"), BorderLayout.NORTH); 
     JME_panel_1.add(new JButton("EAST"), BorderLayout.EAST); 
     JME_panel_1.add(new JButton("SOUTH"), BorderLayout.SOUTH); 
     JME_panel_1.add(ctx1.getCanvas(), BorderLayout.CENTER); 

     JPanel JME_panel_2 = new JPanel(); 
     JSplitPane splitPaneVertical = new JSplitPane(JSplitPane.VERTICAL_SPLIT); 
     splitPaneVertical.add(new JButton("Vertical Button"), JSplitPane.LEFT); 
     splitPaneVertical.add(ctx2.getCanvas(), JSplitPane.RIGHT); 
     JME_panel_2.add(splitPaneVertical); 

     JPanel JME_panel_3 = new JPanel(); 
     JSplitPane splitPaneHorizontal = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT); 
     splitPaneHorizontal.add(new JButton("Horizontal Button"), JSplitPane.TOP); 
     splitPaneHorizontal.add(ctx3.getCanvas(), JSplitPane.BOTTOM); 
     JME_panel_3.add(splitPaneHorizontal); 

     tabbedPane.add(JME_panel_1, "JME border panel"); 
     tabbedPane.add(JME_panel_2, "JME vetical split panel"); 
     tabbedPane.add(JME_panel_3, "JME horizontal split panel"); 

     return tabbedPane; 
    } 

    public static void main(String [] s){ 
     SwingUtilities.invokeLater(new Runnable() { 

      @Override 
      public void run() { 
       SwingApplicationJME app = new SwingApplicationJME(); 
      } 
     }); 
    } 
} 

任何想法請=）

Answer 1

發現的jmonkeyengine文檔上方便的解決方案：Monkey canvas + Swing GUI

這裏是代碼報價：

final JMenuItem itemSwitchTab = new JMenuItem("Switch to tab #2"); 
    menuTortureMethods.add(itemSwitchTab); 
    itemSwitchTab.addActionListener(new ActionListener(){ 
     public void actionPerformed(ActionEvent e){ 
      if (itemSwitchTab.getText().equals("Switch to tab #2")){ 
       canvasPanel1.remove(canvas); 
       canvasPanel2.add(canvas, BorderLayout.CENTER); 
       currentPanel = canvasPanel2; 
       itemSwitchTab.setText("Switch to tab #1"); 
      }else if (itemSwitchTab.getText().equals("Switch to tab #1")){ 
       canvasPanel2.remove(canvas); 
       canvasPanel1.add(canvas, BorderLayout.CENTER); 
       currentPanel = canvasPanel1; 
       itemSwitchTab.setText("Switch to tab #2"); 
      } 
     } 
    }); 

所有我們需要從一個選項卡中刪除畫布和添加到另一個。
