Question

我想实现 按下Button1后 出来个FORM(没有边框的那种) 然后FORM里面有个Lalel1显示WELCOME 3秒后Form渐渐消失

Answer 1

WelFm:=TWelFm.Create(Application)
WelFm.Show;WelFm不要自动动创建
然后在WelFm里放个timer 时间间隔为3000
timer事件里的代码为WelFm.Close;没有测试过..

Answer 2

var
  Test: TForm2;procedure TForm1.Button1Click(Sender: TObject);
begin
  Test := TForm2.Create(Application);
  Test.Show;
  SetWindowLong(Test.Handle, GWL_STYLE, GetWindowLong(Test.Handle, GWL_STYLE) xor
        WS_OVERLAPPEDWINDOW);
  Timer1.Enabled := True;
end;procedure TForm1.Timer1Timer(Sender: TObject);
begin
  AnimateWindow(Test.Handle,1000,AW_HIDE   or   AW_BLEND);
  Test.Close;
end;

Answer 3

procedure TForm1.Button1Click(Sender: TObject);
begin
  with TForm2.Create(nil) do
  begin
    Show;
  end;
end;form2为无边框窗体可以在form2上放置一个timer设置为3秒,然后close

Form1:
unit Unit1;interfaceuses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;var
  Form1: TForm1;implementationuses Unit2;{$R *.dfm}procedure TForm1.Button1Click(Sender: TObject);
begin
  with Form2 do
  begin
    ShowModal;
    Free;
  end;
end;end.Form2:
unit Unit2;interfaceuses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ExtCtrls;type
  TForm2 = class(TForm)
    Label1: TLabel;
    Timer1: TTimer;
    procedure Timer1Timer(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;var
  Form2: TForm2;
  i: Integer;implementation{$R *.dfm}procedure TForm2.Timer1Timer(Sender: TObject);  
begin
  Inc(I);   
  if I > 2 then
    self.Close;
end;end.
