代码文件:

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    TrayIcon1: TTrayIcon;
    Button1: TButton;
    procedure TrayIcon1Click(Sender: TObject);
    procedure FormCloseQuery(Sender: TObject; var CanClose: Boolean);
    procedure Button1Click(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

{关闭}
procedure TForm1.Button1Click(Sender: TObject);
begin
  Application.Terminate;
end;

{点击关闭按钮时让窗体最小化到系统托盘}
procedure TForm1.FormCloseQuery(Sender: TObject; var CanClose: Boolean);
begin
  Tag := Ord(WindowState);
  WindowState := wsMinimized;
  TrayIcon1.SetDefaultIcon;
  TrayIcon1.Visible := True;
  Hide;
  CanClose := False;
end;

{点击系统托盘中的图标恢复窗口}
procedure TForm1.TrayIcon1Click(Sender: TObject);
begin
  TrayIcon1.Visible := False;
  Show;
  WindowState := TWindowState(tag);
  SetForegroundWindow(Handle);
end;

end.
