Delphi：如何使单元格文本在TStringGrid中心对齐？

在TStringGrid中没有任何文本中心的属性,但您可以在DrawCell事件中执行以下操作：

procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol,ARow: Integer;
  Rect: TRect; State: TGridDrawStatE);
var
  S: String;
  SavedAlign: word;
begin
  if ACol = 1 then begin  // ACol is zero based
    S := StringGrid1.Cells[ACol,ARow]; // cell contents
    SavedAlign := SetTextAlign(StringGrid1.Canvas.Handle,TA_CENTER);
    StringGrid1.Canvas.TextRect(Rect,Rect.Left + (Rect.Right - Rect.Left) div 2,Rect.Top + 2,S);
    SetTextAlign(StringGrid1.Canvas.Handle,SavedAlign);
  end;
end;

我从here发布的代码

更新：

在单元格中写入文本时,将此代码添加到GetEditText事件中：

procedure TForm1.StringGrid1GetEditText(Sender: TObject; ACol,ARow: Integer;
  var Value: String);
var
  S : String;
  I: Integer;
  IE : TinplaceEdit ;
begin
  for I := 0 to StringGrid1.ControlCount - 1 do
    if StringGrid1.Controls[i].ClassName = 'TinplaceEdit' then
    begin
      IE := TinplaceEdit(StringGrid1.Controls[i]);
      ie.Alignment := taCenter
    end;
end;
