{ 
 There are two routines to implement the OnColumnClick Methods for a TStringGrid. 
 Set the first row as fixed and the Defaultdrawing to True. 

 Mit folgenden zwei Routinen kann man in einem TStringgrid 
 die Methode OnColumnClick eines TListView erzeugen (visuell). 
 Reihe 0 mu? fixiert sein undDefaultDrawing = True 
}


 type
   TForm1 = class(TForm)
     StringGrid1: TStringGrid;
     procedure StringGrid1MouseDown(Sender: TObject; Button: TMouseButton;
       Shift: TShiftState; X, Y: Integer);
     procedure StringGrid1MouseUp(Sender: TObject; Button: TMouseButton;
       Shift: TShiftState; X, Y: Integer);
   private
     zelle: TRect; // cell 
    acol, arow: Integer;
   public
   end;

 var
   Form1: TForm1;

 implementation

   Shift: TShiftState; X, Y: Integer);

   with stringgrid1 do

     MouseRoCell(x, y, acol, arow);
     if (arow = 0) and (button = mbleft) then
