Linux下的qt编程示例

#include <qapplication.h>
#include "mainform.h"
#include "qtimer.h"

int main( int argc, char ** argv )
{
    QApplication a( argc, argv );
    MainForm w;
    w.show();
    QTimer *date = new QTimer(0);
    QTimer *time = new QTimer(0);
    QObject::connect( date, SIGNAL(timeout()), &w, SLOT(Show_dateSlot()) );
    date->start(1000,FALSE); 
    QObject::connect( time, SIGNAL(timeout()), &w, SLOT(Show_timeSlot()) );
    time->start(500,FALSE);
    a.connect( &a, SIGNAL( lastWindowClosed() ), &a, SLOT( quit() ) );
    return a.exec();
