比较充实的一天：GFx整合有进展

今天终于把BackSpace键删除不了Text Input里面字符的问题给解决了，发现原因是没处理WM_KEYDOWN和WM_KEYUP

就是这几行，呵呵，这是GamebryoGFxApp里面的，拿过来用就好了

         //  Pass windows key messages to GFx
         case  WM_KEYDOWN:
         case  WM_KEYUP:
        {
            GFxKey::Code eKeyCode  =  GFxKey::VoidSymbol;
            WPARAM wCharCode  =  pkEventRecord -> wParam;

             if  (wCharCode  >=   ' A '   &&  wCharCode  <=   ' Z ' )
            {
                eKeyCode  =  (GFxKey::Code) ((wCharCode  -   ' A ' )  +  
                    GFxKey::A);
            }
             else   if  (wCharCode  >=  VK_F1  &&  wCharCode  <=  VK_F15)
            {
                eKeyCode  =  (GFxKey::Code) ((wCharCode  -  VK_F1)  +  
                    GFxKey::F1);
            }
             else   if  (wCharCode  >=   ' 0 '   &&  wCharCode  <=   ' 9 ' )
            {
                eKeyCode  =  (GFxKey::Code) ((wCharCode  -   ' 0 ' )  +  
                    GFxKey::Num0);
            }
             else   if  (wCharCode  >=  VK_NUMPAD0  &&  wCharCode  <=  VK_DIVIDE)
            {
                eKeyCode  =  (GFxKey::Code) ((wCharCode  -  VK_NUMPAD0)  +  
                    GFxKey::KP_0);
            }
             else  
            {
                 for  ( int  i  =   0 ; KeyCodeMap[i].winKey  !=   0 ; i ++ )
                {
                     if  (wCharCode  ==  (UInt)KeyCodeMap[i].winKey)
                    {
                        eKeyCode  =  KeyCodeMap[i].appKey;
                         break ;
                    }
                }
            }
            unsigned  char  asciiCode  =   0 ;
             if  (eKeyCode  !=  GFxKey::VoidSymbol) 
            {
                 //  get the ASCII code, if possible.
                UINT uScanCode  =  
                    ((UINT)pkEventRecord -> lParam  >>   16 )  &   0xFF ;
                BYTE ks[ 256 ];
                WORD charCode;

                 //  Get the current keyboard state
                ::GetKeyboardState(ks);

                 if  (::ToAscii((UINT)wCharCode, uScanCode, ks,  & charCode,  0 ) 
                     >   0 )
                {
                    asciiCode  =  LOBYTE (charCode);
                }
            }

            GFxEvent::EventType eEventType  =  GFxEvent::KeyUp;
             if  (pkEventRecord -> uiMsg  ==  WM_KEYDOWN) 
                eEventType  =  GFxEvent::KeyDown;

             //  Send the key event into the Scaleform movie
            GFxKeyEvent kEvent(eEventType, eKeyCode, asciiCode,  0 );
            m_spGFxManager -> HandleInputEvent(kEvent);

KeyCodeMap

static   struct  
{
    WPARAM winKey;
    GFxKey::Code appKey;
} KeyCodeMap[]  =  
{
    {VK_BACK,    GFxKey::Backspace},
    {VK_TAB,     GFxKey::Tab},
    {VK_CLEAR,   GFxKey::Clear},
    {VK_RETURN,  GFxKey::Return},
    {VK_SHIFT,   GFxKey::Shift},
    {VK_CONTROL, GFxKey::Control},
    {VK_MENU,    GFxKey::Alt},
    {VK_PAUSE,   GFxKey::Pause},
    {VK_CAPITAL, GFxKey::CapsLock},
    {VK_ESCAPE,  GFxKey::Escape},
    {VK_SPACE,   GFxKey::Space},
    {VK_PRIOR,   GFxKey::PageUp},
    {VK_NEXT,    GFxKey::PageDown},
    {VK_END,     GFxKey::End},
    {VK_HOME,    GFxKey::Home},
    {VK_LEFT,    GFxKey::Left},
    {VK_UP,      GFxKey::Up},
    {VK_RIGHT,   GFxKey::Right},
    {VK_DOWN,    GFxKey::Down},
    {VK_INSERT,  GFxKey::Insert},
    {VK_DELETE,  GFxKey::Delete},
    {VK_HELP,    GFxKey::Help},
    {VK_NUMLOCK, GFxKey::NumLock},
    {VK_SCROLL,  GFxKey::ScrollLock},

    {VK_OEM_1,     GFxKey::Semicolon},
    {VK_OEM_PLUS,  GFxKey::Equal},
    {VK_OEM_COMMA, GFxKey::Comma},
    {VK_OEM_MINUS, GFxKey::Minus},
    {VK_OEM_PERIOD,GFxKey::Period},
    {VK_OEM_2,     GFxKey::Slash},
    {VK_OEM_3,     GFxKey::Bar},
    {VK_OEM_4,     GFxKey::BracketLeft},
    {VK_OEM_5,     GFxKey::Backslash},
    {VK_OEM_6,     GFxKey::BracketRight},
    {VK_OEM_7,     GFxKey::Quote}
};

就是这么个小问题，我好几天没解决了，一直盯着WM_CHAR看，就是没看出什么问题来，然后就以为是要在flash文件里做什么特殊设置呢，我靠！flash不熟悉真是痛苦！

我要继续我的痛苦旅程，不经历痛苦就体验不到真正的快乐啊！嘿嘿，问题解决了好爽！

目前整合GFx的工作指导方针如下，因为大的架构已经建立起来了，剩下的就是一些完善工作了：

逢山开路，遇水搭桥，不能追求一步到位，开始用GFx打通流程，在做的过程中逐步完善

下一个待解决的问题：
Q: 如何设置或判断flash里面某个component的focus？因为我要在密码输入框有focus的时候逐字符加密，防止被某些同学盗号……
A: 我要在c++中设置或判断，所以用 GFxMovieView::Invoke
    Button_Login.Focus?
    【2008-10-6】今天用Selection.getFocus()老返回null，没搞清楚原因；Selection.setFocus()倒是好用。类似这种问题太多了，值不值得花费这么多时间在这个东西上？还是研究如何用在场景里吧！这个跟Flash本身没啥关系，不用研究Flash里面的东西。
