Перемещение строк, столбцов и ячеек

Code:

{

The user can move rows and columns of a StringGrid with the mouse.

Can it also be done by code?

In the help for TCustomGrid you can see the methods MoveColumn and MoveRow,

but they are hidden in TStringGrid.

We can make them accessible again by subclassing TStringGrid and

declaring these methods as public:

}

type

TStringGridHack = class(TStringGrid)

public

   procedure MoveColumn(FromIndex, ToIndex: Longint);

   procedure MoveRow(FromIndex, ToIndex: Longint);

end;

{

The implementation of these methods simply consists of invoking the

corresponding method of the ancestor:

}

procedure TStringGridHack.MoveColumn(FromIndex, ToIndex: Integer);

begin

inherited;

end;

procedure TStringGridHack.MoveRow(FromIndex, ToIndex: Integer);

begin

inherited;

end;

// Example, Beispiel:

procedure TForm1.Button1Click(Sender: TObject);

begin

TStringGridHack(StringGrid1).MoveColumn(1, 3);

end;
