菜鸟又来了各位还好啊看看一个简单的但我想了一天的问题.

你可以在JTEXT作FOCUSLOST事件响应，没必要作tab键的响应啊！

bobosji(波波司机):
你的担心我都验证过啦,
我想TAB好象不触发KEYPRESSED事件啊

不应该的，既然定义了VK_tab就能捕捉到，文档里也没有提到不能捕捉tab键，会不会你程序有问题？

to bobosji(波波司机):
系统默认对tab有响应！

：）
TAB肯定触发KEYPRESSED事件的……
应该是你的代码有问题……

我当然验证过的……
能响应TAB键的……
是否你的代码写错了？是“VK_TAB”或者是9……

        default :
            ;//null default
        }    }
}

程序还没做完,可是我现在编译执行无问题.
按F11和F12,F8都有响应,
但TAB没有,
其实我的键盘很好天天用TAB,刚还用过,但
事实上就没有调用KEYPRESSED,我DEBUG过.
简单化一点:
请看核心的代码:
this.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyPressed(KeyEvent e) {
                this_keyPressed(e);
            }
        });void this_keyPressed(KeyEvent e) {
        switch(e.getKeyCode())
        {
        case KeyEvent.VK_F11 :
            ctDangaeStart_actionPerformed(new ActionEvent(this,KeyEvent.VK_F11,""));
        case KeyEvent.VK_F12 :
            ctDangaeEnd_actionPerformed(new ActionEvent(this,KeyEvent.VK_F12,""));
        case KeyEvent.VK_F8 :
            ctApply_actionPerformed(new ActionEvent(this,KeyEvent.VK_F8,""));
        case KeyEvent.VK_TAB :
            System.out.println("this is tab!");//there must some action
        default :
            ;//null default
        }    }谢谢各位,
该软件包不允许用FOCUSLOST(这个事件可以捕捉TAB的).
所以我的程序不好通过了.
再次谢谢各位!

倒，给小日本写的？不用全部贴上来吧？看你最后那部分（没全部看，只看了最后），应该没问题啊（唯一的问题是CASE以后居然没BREAK……）你按下F11有什么反应啊？

有北京的朋友吗,

欢迎大家来玩.

你的程序按了TAB键是在控制台输出啊，你确定控制台没输出？
或者你把标准输出重定向了……
TAB键按下肯定有响应的……

case后当然不用break啦,
你看完ctDangaeStart_actionPerformed就明白了.
当然这样一来就不规范了.按F11后ctxtDangaeStartTime.setText(calSTART_JISSEKI_DATE);执行.
时间被改变了啊.

ender兄谢谢你,
我在控制台输出就是因为不调用过程,
才打印在控制台来看的,
结果还是不行,根本没有.
DEBUG发现就根本没调用啊!

我用的是JB4,
JDK的版本是1.3.0_C
谢谢各位大侠.

我认为可能是你的监听对象不对……
你的按键事件并非发生在JFrame的，而是发生在里面的对象上的，而这些对象默认都有对TAB键的处理，所以这个消息就被消化掉了，传不到JFrame来……而你其他F11等键由于没有默认的处理，所以就传递给JFrame来处理……
你试试在一个TEXTAREA或BUTTON监听，肯定能监听TAB键的……我对JAVA的图形编程不是很熟悉，姑妄言之……

其实你对TEXTAREA作FocusListener的监听，重写public void focusLost(FocusEvent e)方法就可以了！
何必和tab键较劲！

这些对象默认都有对TAB键的处理，所以这个消息就被消化掉了?
我想很有可能,JTEXT什么的也检测不到TAB键.现在没有一点头绪了.

TO：hjfgcx(老鼠)
这样你就只能针对需要捕捉这个按键的对象来监听了……

你试试用public class CtFrmKKG041 extends JFrame implement KeyListener{然后在keyPressed(KeyEvent e){}里判断按键和对象

调试易

菜鸟又来了各位还好啊看看一个简单的但我想了一天的问题.
