unit SplashForm;

interface

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

type
  TSplashForm = class(TForm)
    Timer1: TTimer;
    procedure Timer1Timer(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  SplashForm: TSplashForm;

implementation

{$R *.dfm}

procedure TSplashForm.FormCreate(Sender: TObject);
begin
  // 设置超时时间为3秒
  Timer1.Interval := 3000;
end;

procedure TSplashForm.Timer1Timer(Sender: TObject);
begin
  // 超时事件发生，设置ModalResult为mrTimeout
  ModalResult := mrTimeout;
end;

end.

procedure TForm1.Button1Click(Sender: TObject);
var
  Splash: TSplashForm;
begin
  Splash := TSplashForm.Create(nil);
  try
    // 显示Splash窗体
    if Splash.ShowModal = mrTimeout then
    begin
      // 处理超时事件
      ShowMessage('Splash窗体超时');
    end;
  finally
    Splash.Free;
  end;
end;
