CFrameWnd::CFrameWnd 不能显示tooltips

ussthamcn 2012-09-02 11:56:30

原帖没有人恩回复，我自己不能跟新，新开一个帖子。

研究了下正常的tooltips处理过程应该是
CToolTipsCtrl CToolBar
TTM_GETTOOLINFO ------------>
TTM_GETTOOLINFO<-------------
TTM_ADDTOOL ---------------->
TTM_ADDTOOL <----------------
TTM_ACTIVATE -------
TTM_ACTIVATE -------
TTM_WINDOWFROMPOINT ---------
TTM_WINDOWFROMPOINT ---------
TTM_RELAYEVENT ------------->
TTM_RELAYEVENT <-------------
TTM_DELTOOL ---------------->
TTM_DELTOOL <----------------
我的程序却没有TTM__XXX tooltips消息，不知道消息去哪里了呢

4.PreTranslateMessage中调用m_pfnFilterToolTipMessage指针指向的函数
BOOL CWnd::PreTranslateMessage(MSG* pMsg)
{
// handle tooltip messages (some messages cancel, some may cause it to popup)
AFX_MODULE_STATE* pModuleState = _AFX_CMDTARGET_GETSTATE();
if (pModuleState->m_pfnFilterToolTipMessage != NULL)
(*pModuleState->m_pfnFilterToolTipMessage)(pMsg, this);

// no default processing
return FALSE;
}

整理下今天看的MFC的源代码:
1. CWnd是CToolBar的父类，CWnd有个成员函数FilterToolTipMessage(...)
该函数中过滤tooltips消息TTM_XX, 创建CToolTipCtrl对象，并把地址赋给_AFX_THREAD_STATE的m_pToolTip,并向CToolTipCtrl窗口发送TTM_XX消息.

2. 在CToolBar的父类中, m_toolbar.Create(..CBRS_TOOLTIPS...)
3. DockControlBar(&m_toolbar)的时候调用pBar->SetBarStyle(dwStyle);在SetBarStyle()中调用
EnableToolTips(..),
{
　　　　pModuleState->m_pfnFilterToolTipMessage=CWnd::FilterToolTipMessage
　　｝

我的程序没有Tooltips消息，我的CMainFrame框架类中使用了框架结构VisualFx.h/VisualFx.cpp
有TTabItem/TVisualObject/TVisualFramework这些类
是不是这些消息被这些框架截获了，不过spy++应该能截获这个消息啊，困惑啊
