先上CWnd,WindowProc->OnWndMsg->OnDrawItem
WindowProc直接调用OnWndMsg
LRESULT CWnd::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
// OnWndMsg does most of the work, except for DefWindowProc call
LRESULT lResult = 0;
if (!OnWndMsg(message, wParam, lParam, &lResult))
lResult = DefWindowProc(message, wParam, lParam);
return lResult;
}
OnWndMsg获得msg后通过检索MESSAGE_MAP获得函数地址进行处理
BOOL CWnd::OnWndMsg(UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{

// BEGIN_MESSAGE_MAP(CMyWnd, CMyWnd)
ASSERT(pMessageMap != (*pMessageMap->pfnGetBaseMap)());
if (message < 0xC000)

message, 0, 0)) != NULL)
