graphics3dproperties.java

这个也是一个手机上面的3d例子

import java.util.Enumeration;
import java.util.Hashtable;
import javax.microedition.lcdui.*;
import javax.microedition.m3g.*;
class Graphics3DProperties  extends List  implements CommandListener
{
  private final Maze3DMIDlet midlet;
  Graphics3DProperties(Graphics3D g3d, Maze3DMIDlet midlet)
  {
    super("Graphics 3D Properties", List.IMPLICIT);
    this.midlet = midlet;
    Hashtable props = g3d.getProperties();
    Enumeration propKeys = props.keys();
    while (propKeys.hasMoreElements())
    {
      Object key = propKeys.nextElement();
      append(key.toString() + ": " + props.get(key).toString(), null);
    }
    // some entries are too long
    setFitPolicy(List.TEXT_WRAP_ON);
    addCommand(new Command("Back", Command.BACK, 1));
    setCommandListener(this);
  }
  public void commandAction(Command command, Displayable displayable)
  {
    midlet.showMenu();
  }
}
