Hello
CExtGridCellString::OnQueryTextAreaMargins worked at the time of Prof2.53 well.
( ttp://profuis0.tripod.com/20060607/image03.jpg )
However, a tool tip came to be displayed since Prof2.54.
( ttp://profuis0.tripod.com/20060607/image01.jpg )
------------------------------------------------------------------------
CRect CExtGridCellStringDM2::OnQueryTextAreaMargins(
const CExtGridWnd & wndGrid,
CDC & dc,
LONG nVisibleColNo,
LONG nVisibleRowNo,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType,
DWORD dwAreaFlags,
DWORD dwHelperPaintFlags
) const
{
return CRect( 6, 1, 6, 1 );
}
------------------------------------------------------------------------
In CExtGridWnd-ExtentSet, I made width big, and a tool tip was not displayed.
A problem is already settled.
Thank You

Yes, we changed the algorithm for measuring the cell text and now the OnQueryTextAreaMargins method looks like this: CRect CExtGridCell::OnQueryTextAreaMargins(
const CExtGridWnd & wndGrid,
CDC & dc,
LONG nVisibleColNo,
LONG nVisibleRowNo,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType,
DWORD dwAreaFlags,
DWORD dwHelperPaintFlags
) const
{
ASSERT_VALID( this );
ASSERT_VALID( (&wndGrid) );
ASSERT( dc.GetSafeHdc() != NULL );
wndGrid;
dc;
nVisibleColNo;
nVisibleRowNo;
nColNo;
nRowNo;
nColType;
nRowType;
dwAreaFlags;
dwHelperPaintFlags;
return CRect( 2, 0, 2, 0 );
}So please change your top and bottom margins to zero and let us know whether the problem has gone away: return CRect( 6, 0, 6, 0 );
