Question

我得到的日期格式如下：“2011-04-14 15:00:00”，并希望将它们设置为QDateTimeEdit对象。

我就是这样做的：

void MainWindow::setUIDateAndTime(QString &date)
{
    QDateTime dateTime;
    dateTime.fromString(date, "yyyy-MM-dd hh:mm:ss");

    QString sDatetime = dateTime.toString("yyyy-MM-dd hh:mm:ss"); // For debug testing

    // Create the datetime picker
    QDateTimeEdit *dateTimePicker = new QDateTimeEdit(dateTime);
    dateTimePicker->setObjectName("dateTimePicker");

    ui->frameCommentHolderLayout->addWidget(dateTimePicker);
}

But it never get s set. The debug variable "sDateTime" is always set to "".

Does Anybody see what i do wrong? Thanks in advance.

fromString函数是QDateTime类中的static。这意味着它不会修改dateTime对象的状态。试试这个：

QDateTime dateTime(QDateTime::fromString(date, "yyyy-MM-dd hh:mm:ss"));
