TForm1.CreateLabels()从哪里来的啊

看别人程序时候发现里面有很多诸如：
procedure TDesignForm.CreateLabels();
procedure TDesignForm.UpdateOne(i: Integer; j: Integer);
这样的过程应在什么地方双击写的呢？
而在FORM的事件中只有onActivate和onCreate有内容啊

大家帮我看看哈，谢谢先
程序我贴一部分出来看看的：
unit Design;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, ExtCtrls, Tools; //TOOLS是自己定义的，没有贴出来

type
TDesignForm = class(TForm)
Panel1: TPanel;
Button1: TButton;
Button2: TButton;
Button3: TButton;
procedure FormCreate(Sender: TObject);
procedure FormActivate(Sender: TObject);
procedure UpdateOne(i: Integer; j: Integer);
procedure UpdateAll();
procedure CreateLabels();
procedure LabelMouseEnter(Sender: TObject);
procedure LabelMouseLeave(Sender: TObject);
procedure LabelClick(Sender: TObject);
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
procedure Button3Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
DesignForm: TDesignForm;
m_compArry: TLabelArray;
m_seq: Integer;

implementation

uses Main, ResizeGarage; //使用到其他的单元，自定义的

else

end;

UpdateOne(i, j);
end;

ResizeGarage.ResizeForm.Show;
Self.Hide;
end;

procedure TDesignForm.Button2Click(Sender: TObject);
begin
Main.MainForm.Show;
Self.Hide;
end;

end.
