TList里面装了过程指针，但是不知道怎么把他取出来用。

Answer 1

简单示例如下：
unit Unit1;interfaceuses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;type
  TProcedure = procedure ();
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
  private
    { Private declarations }
    pMyPro:TProcedure;
  public
    { Public declarations }
  end;
procedure APro();var
  Form1: TForm1;implementation{$R *.dfm}procedure TForm1.Button1Click(Sender: TObject);
begin
  pMyPro := apro;
end;procedure APro;
begin
  showmessage('asdfa');
end;procedure TForm1.Button3Click(Sender: TObject);
begin
  pMyPro;
end;end.
