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.

[hjfgcx]

一个JTEXT,
LISTEN KEYPRESSED事件,
可以接受各种键盘消息,
但就不可以接受VK--TAB,
为什么?


更奇怪的是你按TAB的时候他还可以调用FOCUSLOST事件.
但就不能调用KEYPRESSED事件为什么?

[bobosji]

程序贴出来大家看看

[ender]

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……

[mvp2000]

不是代码写错，就是键盘坏掉

[hjfgcx]

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!

[ender]

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？

[hjfgcx]

有北京的朋友吗,
我在北京,
妹儿是[e-mail]
欢迎大家来玩.

[ender]

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……

[hjfgcx]

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.

[hjfgcx]

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!

[hjfgcx]

我用的是JB4,
JDK的版本是1.3.0_C
谢谢各位大侠.

[ender]

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……

[rinehart]

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！

[hjfgcx]

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.

[丝路飞鸿]

高深，看不懂，
唉，什么时候能学会呀，写个非常简单的也行呀！象俄罗斯方块什么的

大家教教我吧

[cds123]

不允许用FOCUSLOST

[ender]

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……

[rox]

关注！

[hjfgcx]

[bobosji]

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
