title: How can I change the font size of the header of a Stringgrid in Delphi Firemonkey XE7?
body: <p>I created a Stringgrid in Delphi Firemonkey XE7 for an application and filled it with data from my MySQL database.
  To enlarge the font size I used this code:</p>
  
  <pre><code>procedure TFormSearchRecipient.sgRecipientDrawColumnCell(Sender: TObject;
    const Canvas: TCanvas; const Column: TColumn; const Bounds: TRectF;
    const Row: Integer; const Value: TValue; const State: TGridDrawStates);
  var b : TRectF; border: integer;
  begin
    //following leaves in the end a border so that the marked item can be seen
    b := bounds;
    border:= 2;
    b.Top := b.Top + border;
    b.Left := b.Left - border;
    b.Height := b.Height - 2 * border;
    b.Width := b.Width - 2 * border;
  
    //colors the background white so that the data cannot be seen anymore
    Canvas.Fill.Color := TAlphaColorRec.White;
    Canvas.FillRect(b, 0, 0, [], 1);
    //change the canvas text options
    Canvas.Fill.Color := TAlphaColorRec.Black;
    Canvas.Font.Size := 25;
    //write the content
    Canvas.FillText(Bounds, Value.AsString , False, 1, [] , TTextAlign.Leading);
  end;
  </code></pre>
  
  <p>I hope some of you can understand what this code does...
  This <a href="http://imgur.com/MUz03ca" rel="nofollow">picture</a> might help.</p>
  
  <p>My question is now: how can I set the header and how can I enlarge the font size of the header or - if that is not possible - how can I disabled, delete or hide the header?</p>
  
  <p>Thanks in advance!</p>
