Hello.



I want to display the tool tip of the specific cell.

I made the following programming.

Is the program good in this?

void XXXGrid::CellToolTip( CExtSafeString strNewTipText , CPoint * pPntFocus )

{

    CExtGridCell *pCell = NULL;

 CPoint ptFocus ;

 ptFocus = FocusGet();

 CRect rc;

 GridCellRectsGet(

         1,

         ptFocus.y ,

         0,

         0,

         NULL,

         &rc

    );

 CRect rcExcludeArea;

 GetWindowRect( &rcExcludeArea );

 rc.left   += rcExcludeArea.left;

 rc.top    += rcExcludeArea.top;

 rc.right  += rcExcludeArea.left;

 rc.bottom += rcExcludeArea.top;

 SetCursorPos( rc.left + rc.Width() / 2  , rc.top + rc.Height() / 2 );

 CExtPopupMenuTipWnd & wndTip = GetTip();

 wndTip.SetText( LPCTSTR(strNewTipText) );

 wndTip.Hide();

 CWnd * pWnd = FromHandle( m_hWnd );

 wndTip.Show( pWnd, rc , true );

}

Please answer it

Your code looks correct. Please check a return value from the GridCellRectsGet() method. If it returns false(), the grid cell is outside the displayed on screen cell range and you should not try to show the tooltip.
