{ This will resize the columns of a TStringGrid / TDrawGrid (text
only!) so the text is completely visble. To save some time,
it uses the first 10 rows only, but that should be easy to fix,
if you need more. }
// we need this to access protected methods
type
TGridHack = class(TCustomGrid);
procedure ResizeStringGrid(_Grid: TCustomGrid);
var
Col, Row: integer;
Grid: TGridHack;
MaxWidth: integer;
ColWidth: integer;
ColText: string;
MaxRow: integer;
ColWidths: array of integer;
begin
Grid := TGridHack(_Grid);
SetLength(ColWidths, Grid.ColCount);
MaxRow := 10;
if MaxRow > Grid.RowCount then
MaxRow := Grid.RowCount;
for Col := 0 to Grid.ColCount - 1 do
begin
MaxWidth := 0;
for Row := 0 to MaxRow - 1 do
begin
ColText := Grid.GetEditText(Col, Row);
ColWidth := Grid.Canvas.TextWidth(ColText);
if ColWidth > MaxWidth then
MaxWidth := ColWidth;
end;
if goVertLine in Grid.Options then
Inc(MaxWidth, Grid.GridLineWidth);
ColWidths[Col] := MaxWidth + 4;
Grid.ColWidths[Col] := ColWidths[Col];
end;
end;
