1.UI文件保存的設(shè)計(jì)缺陷
我們生成.UI文件來保存我們生成的控件數(shù)據(jù),下面是UI結(jié)構(gòu)設(shè)計(jì)圖
這樣的設(shè)計(jì)有缺陷：
以前UI控件最大數(shù)量定CONTROLS_COUNT_MAX= 64，因?yàn)閙_ControlsType為固定數(shù)組，一旦控件數(shù)量超出64，我們就需要將以前的.UI文件轉(zhuǎn)換為現(xiàn)在的UI文件進(jìn)行版本兼容，而我們又不能具體確定好我們的控件上限是多少，每次版本兼容進(jìn)行的轉(zhuǎn)換相當(dāng)麻煩...
改進(jìn)：設(shè)為容器，根據(jù)控件數(shù)量，動(dòng)態(tài)讀取保存到.UI文件中
struct S_UIData
{
struct S_UIHead
{
S_UIHead()
{
memset( m_szVer, 0, sizeof(m_szVer) );
m_nControlsType.resize( CONTROLS_COUNT_MAX );
memset( &m_nControlsType[0], 0, sizeof(m_nControlsType) );
strcpy( m_szVer, UI_VER);
m_nControlsCount = 0;
m_dwCreatedDate = 0;
}
~S_UIHead()
{
m_nControlsType.clear();
}
char m_szVer[10];
DWORD m_dwCreatedDate;
S_FrameData m_stFrameData;
int m_nControlsCount;
//int m_nControlsType[CONTROLS_COUNT_MAX];
vector<int> m_nControlsType;
};
S_UIData();
~S_UIData();
void Release();
DWORD LoadOldFile( const char* pszFileName );
DWORD LoadFile( const char* pszFileName );
DWORD SaveFile( const char* pszFileName );
static S_BaseData* NewData( int nType );
S_UIHead m_stHead;
//S_BaseData *m_pstControlData[CONTROLS_COUNT_MAX];
vector< S_BaseData* > m_pstControlData;
};這個(gè)樣子，以后我們即使控件不夠用了，只需要更改一下上限CONTROLS_COUNT_MAX就OK，但是.UI文件我們卻不需要做版本轉(zhuǎn)換，因?yàn)?UI中的數(shù)據(jù)都是根據(jù)控件數(shù)量來讀取保存的 eg.10個(gè)控件，讀取10個(gè)類型和控件數(shù)據(jù)。

最后需要注意的就是 字節(jié)對(duì)齊 問題

2.UI整體設(shè)計(jì)思路
設(shè)計(jì)思路：我們游戲中的UI常劃分為常見UI模塊，如Friend面板，Property面板,Pack面板,Pet面板等等.
每個(gè)模塊中的單個(gè)UI也處理消息，渲染...
我們創(chuàng)建一個(gè)UIMgr來管理這些大的UI模塊(即UIFrame),每個(gè)UIFrame來管理大模塊中的單個(gè)小UI控件
然后在應(yīng)用程序中分別調(diào)用UIMgr來處理
一句話：app管理UIMgr,UIMgr管理UIFrame, UIFrame管理單個(gè)UI控件（UI_Object)
我們的應(yīng)用程序擁有主要函數(shù):
virtual HRESULT FrameMove(); //更新
virtual HRESULT Render(); //渲染
virtual LRESULT MsgProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam );
分別調(diào)用 theUIMgr.FrameMove(), theUIMgr.Render(), theUIMgr().MsgProc(...)
theUIMgr是一個(gè)UIFrame的容器 vector<UIFrame*> vecFrame;
內(nèi)部調(diào)用UIFrame的消息處理
for( int i = 0; i < vecFrame.size(); i++ )
vecFrame[i]->FrameMove();
vecFrame[i]->Render();
vecFrame[i]->OnMouseMove(...);
vecFrame[i]->OnLButtonDown(...);
vecFrame[i]->MsgProc(...);
UIFrame是單個(gè)UI控件的容器 vector<UI_Object*> m_vecChild;
for( int i = 0; i < m_vecChild.size(); i++ )
m_vecChild[i]->FrameMove();
....
m_vecChild[i]->Render();
....
m_vecChild[i]->OnMouseMove(...);
所有的UI消息都能夠處理了，所有處理要依據(jù)先后關(guān)系，如一個(gè)面板消息被一個(gè)UI處理后，那么要返回true，
其他的UI將不會(huì)重復(fù)處理
問題是我們會(huì)將我們的UI做成一個(gè)UI 靜態(tài)庫,那么我們按鈕按下觸發(fā)的功能，無法提前設(shè)置好，
解決方法： 設(shè)置回調(diào)函數(shù)
eg:
CHR_UI_Frame下的回調(diào)函數(shù)接口
typedef bool (*funOnClick)( OUT CHR_UI_Object* pSender );
typedef bool (*funOnRBtnDown)( OUT CHR_UI_Object* pSender );
typedef bool (*funRun)(void);
typedef bool (*funRender)(void);
CHR_UI_Edit下的回調(diào)函數(shù)指針
typedef void (*funOnEnter)( OUT CHR_UI_Object* pSender, OUT const char *szData );
typedef void (*funOnTab)( OUT CHR_UI_Object* pSender, OUT const char* szData);
CHR_UI_Button下的函數(shù)接口
typedef bool (*funOnButtonClick)( OUT CHR_UI_Object* pSender );
...
在WM_LBUTTONUP中調(diào)用觸發(fā)
if ( m_pFunOnButtonClick ) //函數(shù)指針
{
if ( m_pFunOnButtonClick( this ) == false )
{
if ( m_pFather && strcmp( m_pstData->m_szID, "ID_BUTTON_CLOSE" ) == 0 )
{
m_pFather->SetVisable( false );
}
}
}
m_pID_BUTTON_SelectRole.SetButtonClickFunc( ID_BUTTON_SELECTROLEOnButtonDown );
