Create a customer TPanel component

Hi all,

I am trying to create a custom TPanel component.
On the panel i require another panel at the top and a Listview at the bottom.
The size of the main panel is only going to be 100x100.

I need it this way as I need 26 of these components on 1 page, plus I can store specific objects against each of the components.

Having trouble getting this to work so any help appreciated.

Maybe Frame is a good choice?

Personally I would rather have an example of an extended panel than using a frame if someone had some code.

So try to create a frame.
File | New | Frame
place any component on it
And then on each form of Your application You can place using Frame component from Standard components

here's an example I wrote for you.
You can easily turn this into a VCL (so you can use it in design mode) by adding a "register" method

unit Unit1;

interface


uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  ExtCtrls, ComCtrls, StdCtrls;

type TMyPanel = class(TPanel)
  public
    TopPanel: TPanel;
    ListView: TListView;
    constructor Create(AOwner: TComponent); override;
    destructor Destroy; override;
end;

type
  TForm1 = class(TForm)
    Button_Make26Panels: TButton;
    procedure Button_Make26PanelsClick(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

{ TMyPanel }

constructor TMyPanel.Create(AOwner: TComponent);
const
  def_mainpanelheight = 100;
  def_mainpanelwidth = 100;
  def_toppanelheight = 50;
begin
  inherited Create(AOwner);
  self.Height := def_mainpanelheight;
  self.Width := def_mainpanelwidth;
  TopPanel := TPanel.Create(self);
  with TopPanel do
  begin
    Parent := self;
    Height := def_toppanelheight;
    Align := alTop;
  end;
  ListView := TListView.Create(self);
  with ListView do
  begin
    Parent := self;
    Align := alClient;
  end;
end;

destructor TMyPanel.Destroy;
begin
  if assigned(TopPanel) then FreeAndNil(TopPanel);
  if assigned(ListView) then FreeAndNil(ListView);
  inherited Destroy;
end;

procedure TForm1.Button_Make26PanelsClick(Sender: TObject);
var
  col, row: integer;
  newpanel: TMyPanel;
  i: integer;
begin
  i := 0;
  for col := 1 to 13 do
    for row := 1 to 13 do
    begin
      inc(i);
      newpanel := TMyPanel.Create(Form1);
      with newpanel do
      begin
        Left := (col-1) * 102;
        top := (row-1) * 102;
        TopPanel.Caption := IntToStr(i);
        Parent := Form1;
      end;
    end;
end;

end.
