本文為大家詳細(xì)介紹下delphi判斷程序30秒沒有鍵盤和鼠標(biāo)動作,這里給timer設(shè)置了1000ms)的參數(shù),表示30秒的間隔,具體實(shí)現(xiàn)如下,感興趣的朋友可以參考下哈
以下為原代碼:
(這里給timer設(shè)置了1000ms)的參數(shù),表示30秒的間隔??!
復(fù)制代碼 代碼如下:

unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, ExtCtrls;
type
TForm1 = class(TForm)
Memo1: TMemo;
Button1: TButton;
Timer1: TTimer;
procedure Timer1Timer(Sender: TObject);
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
procedure AppMessageHandler(var Msg:TMsg;var Handled:Boolean);
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
{ TForm1 }
procedure TForm1.AppMessageHandler(var Msg: TMsg; var Handled: Boolean);
begin
if (msg.message=WM_MOUSEMOVE) or (msg.message=WM_KEYDOWN) then timer1.tag:=0;
end;
procedure TForm1.Timer1Timer(Sender: TObject);
begin
timer1.tag:=timer1.tag+1;
if Timer1.tag=30 then close;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
close;
end;
end.
