QDateTimeEdit及QDateTime的使用

    QString strYear = ui->dateTimeEdit->sectionText(QDateTimeEdit::YearSection);
    QString strMonth = ui->dateTimeEdit->sectionText(QDateTimeEdit::MonthSection);
    QString strDay = ui->dateTimeEdit->sectionText(QDateTimeEdit::DaySection);
    QString strHour = ui->dateTimeEdit->sectionText(QDateTimeEdit::HourSection);
    QString strMinute = ui->dateTimeEdit->sectionText(QDateTimeEdit::MinuteSection);
    QString strSecond = ui->dateTimeEdit->sectionText(QDateTimeEdit::SecondSection);

    QString strTime = ui->dateTimeEdit->dateTime().toString("yyyy-MM-dd HH:mm:ss");
    m_dtStart = QDateTime::fromString("2021-09-17 00:11:00", "yyyy-MM-dd HH:mm:ss");
    m_dtStart = ui->dateTimeEdit->dateTime();


//时间增加秒
QString MainWindow::GetTimeStr(int addSecs)
{
    QDateTime dtFinal = m_dtStart.addSecs(addSecs);
    QString ret = dtFinal.toString("yyyy-MM-dd HH:mm:ss");
    return ret;
}
