statusbar 显示 toolbar的text

[小呆呆呆]

我现在有个程序，当我鼠标移动到tool bar上面时候，status bar的text改为tool bar的text.

ON_UPDATE_COMMAND_UI (ID_INDICATOR_TIME, OnUpdateTime)
上面的函数我也没找到， 请问是如何做到的？

不是这样子的 你打开你的工程到资源里找到工具条 比如工具条的ID是ID_TOOLBAR1，打开它的属性下面不是有个“提示”嘛，输入“工具条\n工具条” “\n”前面的部分是你鼠标放到工具条按钮上显示的内容，后面就是你状态栏显示的内容啦

主要都是框架类的功劳，F11进入CFrameWnd类的
WM_SETMESSAGESTRING消息响应函数

LRESULT CFrameWnd::OnSetMessageString(WPARAM wParam, LPARAM lParam)
{
	UINT nIDLast = m_nIDLastMessage;
	m_nFlags &= ~WF_NOPOPMSG;

	CWnd* pMessageBar = GetMessageBar();
	if (pMessageBar != NULL)
	{
		LPCTSTR lpsz = NULL;
		CString strMessage;

		// set the message bar text
		if (lParam != 0)
		{
			ASSERT(wParam == 0);    // can't have both an ID and a string
			lpsz = (LPCTSTR)lParam; // set an explicit string
		}
		else if (wParam != 0)
		{
			// map SC_CLOSE to PREVIEW_CLOSE when in print preview mode
			if (wParam == AFX_IDS_SCCLOSE && m_lpfnCloseProc != NULL)
				wParam = AFX_IDS_PREVIEW_CLOSE;

			// get message associated with the ID indicated by wParam
			GetMessageString(wParam, strMessage);
			lpsz = strMessage;
		}
		pMessageBar->SetWindowText(lpsz);

		// update owner of the bar in terms of last message selected
		CFrameWnd* pFrameWnd = pMessageBar->GetParentFrame();
		if (pFrameWnd != NULL)
		{
			pFrameWnd->m_nIDLastMessage = (UINT)wParam;
			pFrameWnd->m_nIDTracking = (UINT)wParam;
		}
	}

	m_nIDLastMessage = (UINT)wParam;    // new ID (or 0)
	m_nIDTracking = (UINT)wParam;       // so F1 on toolbar buttons work
	return nIDLast;
}
