QTimer定时器以及QTime获取时间

实例：

#include <QTime>#include <QTimer>{    QTimer *myTimer;    myTimer=new QTimer(this);    myTimer->start(1000);    connect(myTimer,SIGNAL(timeout()),this,SLOT(getDateTime()));}void MainWindow::getDateTime(){    ui->label_time->setText(QTime::currentTime().toString());    ui->label_date->setText(QDate::currentDate().toString(tr("yyyy-MM-dd dddd")));}
