Question

I have a TPanel on a delphi form, I want to copy all the TLabels
parented with this TPanel when i press a button and put them
in other panel.
Is there a way to do that?
Thanks.

To copy the TLabel controls from one TPanel to another you can use something like this

Procedure CopyLabels(ParentControl,DestControl:TWinControl);
var
 i      : integer;
 ALabel : TLabel;
begin
  for i := 0 to ParentControl.ControlCount - 1 do
   if ParentControl.Controls[i] is TLabel then
    begin
       ALabel:=TLabel.Create(DestControl);
       ALabel.Parent :=DestControl;
       ALabel.Left   :=ParentControl.Controls[i].Left;
       ALabel.Top    :=ParentControl.Controls[i].Top;
       ALabel.Width  :=ParentControl.Controls[i].Width;
       ALabel.Height :=ParentControl.Controls[i].Height;
       ALabel.Caption:=TLabel(ParentControl.Controls[i]).Caption;
       //you can add manually more properties here like font or another 
    end;
end;

and use like this

CopyLabels(Panel1,Panel2);

you can use the RTTI too, to copy the properties from a control to another, but as you does not specify your Delphi version only i show a simple example.
