wwLayoutGrid question

Hello,  I am looking for some suggestions on how I could use a wwLayoutGrid (or other FirePower controls) to accomplish the task of displaying a "Conversation" similar to the way an iPhone displays text communications.  This would show the user's conversation entries on the right side and the other person's entries on the left side.   I would also need the ability to show the date/time of the conversation above (or below) each entry. 

Any suggestions would be greatly appreciated.

Thank you

  You could change the drawrect location by using the OnCustomDrawControl event. For instance, the following code moves a control to the right under certain conditions.

  procedure TMainDemoForm.lgDemoCustomDrawControl(Sender: TObject;
    CellAttributes: TwwCustomDrawControlAttributes);
  var r: TRectF;
  begin
    if (CellAttributes.Control=lblNewFeatures) or
       (CellAttributes.Control=lblChildNewFeatures) then
    begin
      if not (CellAttributes.GetValue('NewFeatures').AsBoolean) then
      begin
        r:= CellAttributes.DrawRect;
        r.left:= r.right - 50;
        r.right:= r.left + CellAttributes.DrawRect.Width;
        CellAttributes.DrawRect:=r;
      end;
    end;
  end;
