QT 定时器使用

1.
    
    
    
    

     
     
     
     
 QTimer *timer = new QTimer( myObject );
 connect( timer, SIGNAL(timeout()), myObject, SLOT(timerDone()) );
 timer->start( 2000, TRUE ); // 2秒单触发定时器
    
    
    
    
 QTimer *t = new QTimer( myObject ); 
connect( t, SIGNAL(timeout()), SLOT(processOneThing()) );
 t->start( 2000, FALSE ); // 2秒单触发定时器

2.void QTimer::singleShot ( int msec, QObject * receiver, const char * member ) [静态] 
QTimer::singleShot( 10*60*1000, &a, SLOT(quit()) );
