CMFCToolBarEditBoxButton::OnUpdateToolTip

  • Article

Called by the framework when the parent toolbar updates its tooltip text.

virtual BOOL OnUpdateToolTip(
   CWnd* pWndParent,
   int iButtonIndex,
   CToolTipCtrl& wndToolTip,
   CString& str
);

Parameters

  • [in] pWndParent
    Unused.

  • [in] iButtonIndex
    Unused.

  • [in] wndToolTip
    The control that displays the tooltip text.

  • [out] str
    A CString object that receives the updated tooltip text.

Return Value

Nonzero if the method updates the tooltip text; otherwise 0.

Remarks

This method extends the base class implementation (CMFCToolBarButton::OnUpdateToolTip) by displaying the tooltip text that is associated with the edit part of the button. If the internal CEdit object is NULL or the window handle of the CEdit object does not identify an existing window, this method does nothing and returns FALSE.
