Question

我一直在寻找一个没有运气的解决方案。有谁知道一个简单的方法吗？我想拉伸我的网格的第二列以适应网格的宽度！

Answer 1

使用ColWidths属性，如下所示：

with StringGrid1 do
  ColWidths[1] := ClientWidth - ColWidths[0] - 2 * GridLineWidth;

要获得更强大，更灵活的解决方案，请考虑所有固定列并参数化列索引：

procedure SetColumnFullWidth(Grid: TStringGrid; ACol: Integer);
var
  I: Integer;
  FixedWidth: Integer;
begin
  with Grid do
    if ACol >= FixedCols then
    begin
      FixedWidth := 0;
      for I := 0 to FixedCols - 1 do
        Inc(FixedWidth, ColWidths[I] + GridLineWidth);
      ColWidths[ACol] := ClientWidth - FixedWidth - GridLineWidth;
    end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  SetColumnFullWidth(StringGrid1, 4);
end;

Answer 2

解决方案如果有更多疑问命令“ grid.AutoFitColumns（）” grid是一个“TAdvStringGrid”;

Answer 3

以下代码与FixedCols = 0配合使用（以适应其他值，例如：FixedCols = 1 ==> for Col := 1 to ...）

procedure AutoSizeGridColumns(Grid: TStringGrid);
const
  MIN_COL_WIDTH = 15;
var
  Col : Integer;
  ColWidth, CellWidth: Integer;
  Row: Integer;
begin
  Grid.Canvas.Font.Assign(Grid.Font);
  for Col := 0 to Grid.ColCount -1 do
  begin
    ColWidth := Grid.Canvas.TextWidth(Grid.Cells[Col, 0]);
    for Row := 0 to Grid.RowCount - 1 do 
    begin
      CellWidth := Grid.Canvas.TextWidth(Grid.Cells[Col, Row]);
      if CellWidth > ColWidth then
        Grid.ColWidths[Col] := CellWidth + MIN_COL_WIDTH
      else
        Grid.ColWidths[Col] := ColWidth + MIN_COL_WIDTH;
    end;
  end;
end;

Answer 4

像这样更好：

procedure AutoSizeGridColumns(Grid: TStringGrid);
const
  MIN_COL_WIDTH = 15;
var
  Col : Integer;
  ColWidth, CellWidth: Integer;
  Row: Integer;
begin
  Grid.Canvas.Font.Assign(Grid.Font);
  for Col := 0 to Grid.ColCount -1 do
  begin
    ColWidth := Grid.Canvas.TextWidth(Grid.Cells[Col, 0]);
    for Row := 0 to Grid.RowCount - 1 do 
    begin
      CellWidth := Grid.Canvas.TextWidth(Grid.Cells[Col, Row]);
      if CellWidth > ColWidth then
        ColWidth := CellWidth
    end;
    Grid.ColWidths[Col] := ColWidth + MIN_COL_WIDTH;
  end;
end;

如何使String Grid列符合网格宽度？
