duilib版本367
duilib 这个版本也集成了类似MFC的消息宏，懂MFC的朋友应该很容易就弄明白了，也可以参考《深入浅出MFC》里对消息宏的讲解。
typedef void (CNotifyPump::*DUI_PMSG)(TNotifyUI& msg); //指针类型
//结构定义
struct DUI_MSGMAP_ENTRY //定义一个结构体，来存放消息信息
{
CDuiString sMsgType; // DUI消息类型
CDuiString sCtrlName; // 控件名称
UINT nSig; // 标记函数指针类型
DUI_PMSG pfn; // 指向函数的指针
};
struct DUI_MSGMAP
{
#ifndef UILIB_STATIC
const DUI_MSGMAP* (PASCAL* pfnGetBaseMap)(); //返回消息映射
#else
const DUI_MSGMAP* pBaseMap; //返回基类的DUI_MSGMAP*
#endif
const DUI_MSGMAP_ENTRY* lpEntries; //消息实体指针
};

WindowImplBase 继承 CCNotifyPump 在Notify方法中，将消息发给NotifyPump
void WindowImplBase::Notify(TNotifyUI& msg)
{
return CNotifyPump::NotifyPump(msg);
}然后：
void CNotifyPump::NotifyPump(TNotifyUI& msg)
{
///遍历虚拟窗口
if( !msg.sVirtualWnd.IsEmpty() ){
for( int i = 0; i< m_VirtualWndMap.GetSize(); i++ ) {
if( LPCTSTR key = m_VirtualWndMap.GetAt(i) ) {
if( _tcsicmp(key, msg.sVirtualWnd.GetData()) == 0 ){
CNotifyPump* pObject = static_cast<CNotifyPump*>(m_VirtualWndMap.Find(key, false));
if( pObject && pObject->LoopDispatch(msg) )
return;
}
}
}
}
///
//遍历主窗口
LoopDispatch( msg );
}
static const DUI_MSGMAP_ENTRY* DuiFindMessageEntry(const DUI_MSGMAP_ENTRY* lpEntry,TNotifyUI& msg )
{
CDuiString sMsgType = msg.sType;
CDuiString sCtrlName = msg.pSender->GetName();
const DUI_MSGMAP_ENTRY* pMsgTypeEntry = NULL;
while (lpEntry->nSig != DuiSig_end)
{
if(lpEntry->sMsgType==sMsgType)
{
if(!lpEntry->sCtrlName.IsEmpty())
{
if(lpEntry->sCtrlName==sCtrlName)
{
return lpEntry;
}
}
else
{
pMsgTypeEntry = lpEntry;
}
}
lpEntry++;
}
return pMsgTypeEntry;
}获取到对应的DUI_MSGMAP_ENTRY
bool CNotifyPump::LoopDispatch(TNotifyUI& msg)
{
const DUI_MSGMAP_ENTRY* lpEntry = NULL;
const DUI_MSGMAP* pMessageMap = NULL;
#ifndef UILIB_STATIC

if ((lpEntry = DuiFindMessageEntry(pMessageMap->lpEntries,msg)) != NULL)
{

}
}
return false;
