我正在玩JME3,目前面临以下问题：

当LWJGL画布包含在多个应用程序选项卡中时,它们都不会或仅运行一次.

这是一个例子：

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();

}

});

}

}

任何想法请=)
