-// TooltipManager implementation for Windows.
-//
-// This class is intended to be used by NativeWidgetWin. To use this, you must
-// do the following:
-// Add the following to your MSG_MAP:
-//
-//   MESSAGE_RANGE_HANDLER(WM_MOUSEFIRST, WM_MOUSELAST, OnMouseRange)
-//   MESSAGE_RANGE_HANDLER(WM_NCMOUSEMOVE, WM_NCMOUSEMOVE, OnMouseRange)
-//   MSG_WM_NOTIFY(OnNotify)
-//
-// With the following implementations:
-//   LRESULT XXX::OnMouseRange(UINT u_msg, WPARAM w_param, LPARAM l_param,
-//                             BOOL& handled) {
-//     tooltip_manager_->OnMouse(u_msg, w_param, l_param);
-//     handled = FALSE;
-//     return 0;
-//   }
-//
-//   LRESULT XXX::OnNotify(int w_param, NMHDR* l_param) {
-//     bool handled;
-//     LRESULT result = tooltip_manager_->OnNotify(w_param, l_param, &handled);
-//     SetMsgHandled(handled);
-//     return result;
-//   }
-//
-// And of course you'll need to create the TooltipManager!
-//
-// Lastly, you'll need to override GetTooltipManager.
-//
-// See NativeWidgetWin for an example of this in action.
