下面的程序是使 dbgrid 自动适应网格的宽度.也是 盒子 上一位大哥写的, 现在我用 dbgrideh .我要怎样该呢? unit Unit2; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, Grids, DBGridEh, StdCtrls, DB, ADODB, DBGrids,math; function DBGridRecordSize(mColumn: TColumn): Boolean; function DBGridAutoSize(mDBGrid: TDBGrid; mOffset: Integer = 5): Boolean; implementation function DBGridRecordSize(mColumn: TColumn): Boolean; { 返回记录数据网格列显示最大宽度是否成功 } begin Result := False; if not Assigned(mColumn.Field) then Exit; mColumn.Field.Tag := Max(mColumn.Field.Tag, TDBGrid(mColumn.Grid).Canvas.TextWidth(mColumn.Field.DisplayText)); Result := True; end; { DBGridRecordSize } function DBGridAutoSize(mDBGrid: TDBGrid; mOffset: Integer = 5): Boolean; { 返回数据网格自动适应宽度是否成功 } var I: Integer; begin Result := False; if not Assigned(mDBGrid) then Exit; if not Assigned(mDBGrid.DataSource) then Exit; if not Assigned(mDBGrid.DataSource.DataSet) then Exit; if not mDBGrid.DataSource.DataSet.Active then Exit; for I := 0 to mDBGrid.Columns.Count - 1 do begin if not mDBGrid.Columns[I].Visible then Continue; if Assigned(mDBGrid.Columns[I].Field) then mDBGrid.Columns[I].Width := Max(mDBGrid.Columns[I].Field.Tag, mDBGrid.Canvas.TextWidth(mDBGrid.Columns[I].Title.Caption)) mOffset else mDBGrid.Columns[I].Width := mDBGrid.Canvas.TextWidth(mDBGrid.Columns[I].Title.Caption) mOffset; mDBGrid.Refresh; end; Result := True; end; { DBGridAutoSize } ///////End Source end. yyu10 大哥，我要怎么改写这两个函数呢？ 谢谢！
