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;
