鼠标窗体是什么样的东西？

[逃逃VS海]

当用软件时，把鼠标移动到某个图标上，软件会自动弹出一个半透明的窗体，上面会介绍该图标的说明。
不知道VC里是否提供这种类，功能，请大家赐教下。

cToolTip类，详见MSDN
e.g:

int CMyWnd::OnCreate()
{
...
CString str("Helpful Info");
m_ToolTip.Create(this);
m_ToolTip.AddTool(this,str);
...
}

code from msdn.

// Create and associate a tooltip control to the tab control of 
// CMyPropertySheet.  CMyPropertySheet is a CPropertySheet-derived
// class.
BOOL CMyPropertySheet::OnInitDialog() 
{
   BOOL bResult = CPropertySheet::OnInitDialog();
   
   // Create a tooltip control.  m_ToolTipCtrl is a member variable
   // of type CToolTipCtrl* in CMyPropertySheet class.  It is 
   // initialized to NULL in the constructor, and destroyed in the 
   // destructor of CMyPropertySheet class.
   m_ToolTipCtrl = new CToolTipCtrl;
   if (!m_ToolTipCtrl->Create(this))
   {
      TRACE("Unable To create ToolTip\n");           
      return bResult;
   }

   // Associate the tooltip control to the tab control
   // of CMyPropertySheet.
   CTabCtrl* tab = GetTabControl();
   tab->SetToolTips(m_ToolTipCtrl);

   // Get the bounding rectangle of each tab in the tab control of the
   // property sheet. Use this rectangle when registering a tool with 
   // the tool tip control.  IDS_FIRST_TOOLTIP is the first ID string 
   // resource that contains the text for the tool.
   int count = tab->GetItemCount();
   int id = IDS_FIRST_TOOLTIP;
   for (int i = 0; i < count; i++)
   {
      id += i;
      CRect r;
      tab->GetItemRect(i, &r);
      VERIFY(m_ToolTipCtrl->AddTool(tab, id, &r, id));
   }

   // Activate the tooltip control.
   m_ToolTipCtrl->Activate(TRUE);

   return bResult;
}

// Override PreTranslateMessage() so RelayEvent() can be 
// called to pass a mouse message to CMyPropertySheet's 
// tooltip control for processing.
BOOL CMyPropertySheet::PreTranslateMessage(MSG* pMsg) 
{
   if (NULL != m_ToolTipCtrl)            
      m_ToolTipCtrl->RelayEvent(pMsg);
   
   return CPropertySheet::PreTranslateMessage(pMsg);
}
