lwuit LIST如何横向滚动
我采用了网上一位牛人写的LIST (LWUIT)表格实现我的表格,经过调试发现设置form.setScrollabe(false)就可以实现竖向滚动,但
怎么调也调不出来横向的滚动,想来这里求教一下,希望各位高手帮忙.
Java code

package com.onest.xmair.test;



import com.sun.lwuit.Component;
import com.sun.lwuit.Container;
import com.sun.lwuit.Label;
import com.sun.lwuit.List;
import com.sun.lwuit.events.ActionListener;
import com.sun.lwuit.layouts.BorderLayout;
import com.sun.lwuit.layouts.BoxLayout;
import com.sun.lwuit.list.ListCellRenderer;
import com.sun.lwuit.plaf.Border;


public class Cls_CellList {

    static public List createList(CellList[] celllist,int stringWidth,ActionListener lAListner) {
        List list = new List(celllist);
        
        list.getStyle().setBgTransparency(0);

        //开始显示List
        list.setListCellRenderer(new CellRenderer(celllist[0].getColumm().length, stringWidth));
        //添加消息处理
        list.addActionListener(lAListner);
        return list;
    }
    
 static public class CellRenderer extends Container implements ListCellRenderer {

        //初始化显示Columm每个字段的Label
        private Label[] lbColumm ;
        private Label focus = new Label("");

        public CellRenderer(int size,final int stringWidth) {
            lbColumm = new Label[size];
            setLayout(new BorderLayout());
            Container cnt = new Container(new BoxLayout(BoxLayout.X_AXIS));
            for(int i=0; i < lbColumm.length; i ++)//定义显示Columm每个字段的Label
            {
                lbColumm[i] = new Label(){
                    //很多人都问怎么setWidth平时没什么用,这是因为setWidth必须在重载的时候使用,LWUIT奇怪的地方之一!
                    public void setWidth(int arg0) {
                        super.setWidth(stringWidth);
                    }
                };
                //设置为最亮的颜色
                lbColumm[i].getStyle().setFgColor(getStyle().getFgSelectionColor());
                //设置背景为透明,不然会遮挡focus影响外观
                lbColumm[i].getStyle().setBgTransparency(0);
                // 新增代码
                lbColumm[i].setFocusable(true);
                cnt.addComponent(lbColumm[i]);
            }
            // 新增代码
            cnt.setFocusable(true);
            //cnt.setScrollableX(true);

            addComponent(BorderLayout.CENTER, cnt);
            focus.getStyle().setBgTransparency(255);
            focus.getStyle().setBorder(Border.createRoundBorder(10, 10));
        }

        public Component getListCellRendererComponent(List list, Object value, int index, boolean isSelected) {
            
            CellList cellList = (CellList) value;
            for(int i=0;i<lbColumm.length;i++)
            {
                lbColumm[i].setText(cellList.getColumm()[i]);
            }
            
            return this;
        }

        public Component getListFocusComponent(List list) {
            //Columm栏不具备选中事件
            if(list.getSelectedIndex()>0) {
                return focus;
            }
            return null;
        }

    }

    static public class CellList {
        //保存该列的所有字段
        private String[] lstColumm;
        
        public CellList(String[] columm) {
            //复制数组
            lstColumm=new String[columm.length];
            System.arraycopy(columm, 0, lstColumm, 0, lstColumm.length);
         }
        
        //返回该列
        public String[] getColumm(){
