请哪位好心人告诉我几个 Navigation key 的keyCode的宏定义

[daijuntang]

请哪位好心人告诉我几个 Navigation key 的keyCode的宏定义：
Arrow up
Arrow down
Arrow left
Arrow right
The Selection key

虽然可以测出来上述key的code，但总 不能hardcode在代码中吧，查了半天也没有找到。麻烦哪位好心人告诉我，非常感谢！

参考e32keys.h
Developer Library » API Reference » C++ API reference » Window Server » TKeyCode

[daijuntang]

非常感谢PeterJiang的帮助。
不过我原来就试过Enum TKeyCode 中定义的如下key code：

EKeyLeftArrow
EKeyRightArrow
EKeyUpArrow
EKeyDownArrow
EKeyEnter

但发现上述定义和实际的手机键盘事件函数
TKeyResponse CCoeControl::OfferKeyEventL(
const TKeyEvent& aKeyEvent, TEventCode aType )中
aKeyEvent.iCode的值不一致。
（注意，如果在模拟器中运行，而且是按计算机键盘事件，上述宏和实际的运行值一致）

[PeterJiang]

我在程序中使用是正常的,但注意不是EKeyEnter而是EKeyOK

TInt code = aKeyEvent.iCode;
switch(code)
{
case EKeyOK:
	//your code
	return EKeyWasConsumed;
	break;
case EKeyUpArrow:
	//your code
	return EKeyWasConsumed;
	break;
case EKeyDownArrow:
	//your code
	return EKeyWasConsumed;
	break;
default:
	return EKeyWasNotConsumed;
	break;
}

sorry，补充一下，上面的所有keycode在实机和模拟器上都能正确运行。
不过我不是使用series，用的其他平台。
祝好运

try:

if(aType == EEventKeyDown)
{
	switch(aKeyEvent.iScanCode)
	{
		case EStdKeyLeftArrow:
                                 ...
                                 break;
		case EStdKeyRightArrow:
                                 ...
                                 break;
		case EStdKeyUpArrow:
                                 ...
                                 break;
		case EStdKeyDownArrow:
                                 ...
                                 break;
		case EStdKeyDevice3://ok key
                                 ...
                                 break;

也可以设置断点，看看实际到底什么值

非常感谢PeterJiang，SymbianLN，hoolee的热心帮助。

综合大家的建议，我今天又仔细试了几遍.

我的环境是Symbian 8.0a S60_2nd_FP2_SC 。

实际代码的测试结果如下：

TKeyResponse CMyTestAppUi_HandleKeyEventL( const TKeyEvent& aKeyEvent,
                                             TEventCode aType )
{
    switch( aKeyEvent.iCode )
    {
    case EKeyLeftArrow: // 63495 
        break ;
    case EKeyRightArrow: // 63496
        break;
    case EKeyUpArrow: // 63497
        break;
    case EKeyDownArrow: // 63498
        break;
    case EKeyDevice3:  //  63557 Navigation Selection key 
        break;
    }
    return( EKeyWasNotConsumed );
} 

上述Key Code 的枚举定义在<e32keys.h>中的enum TKeyCode。

这个文件中有两套key code的定义，一套是enum TStdScanCode，另一套是
enum TKeyCode。

对不起，借贴提个问题
〉〉两套key code的定义，一套是enum TStdScanCode，另一套是enum TKeyCode。
上面的这两个定义，我也看到过。不过我使用的都是TKeyCode，包括FEP输入的场合。
我曾经在画面处理key事件的时候，也尝试过Scancode，但遇到了问题，好像是code值不符，1年前的事情记不清楚了。
SDK的文档也看过了，但是体会不深。
拜托各位如果了解的话，请详细的说明一下。
谢谢大家。

和同事讨论了一下，关于TStdScanCode和TKeyCode，有了以下几点看法。
1，一般情况下，两者使用哪个都可以，但是对于同一个键，他们的value是不同的
我自己的话，常常选择icode在offerkeyeventl函数中处理
2，组合键的情况下，需要通过iscancode记忆按下的几个键，这时候是要用到TStdScanCode
3，有外界键盘的时候，需要使用icode，因为TKeyCode能够支持外挂。
抛砖引玉，希望各位多多指点
