QT中逐行从QTextEdit中获取数据

Question

你好，我想从Qt中的TextEdit中逐行获取信息并写入它在向量中。怎么可能呢谢谢。想得到 vectorarr = {"{9,1,6,6}","{0,4,3,11}","{3,22,8,33}","{11,3,8 ,3}"};

Answer 1

您可以获得所有 QTextEdit 文本并将其拆分为 \n（新行）。

获取QTextEdit文本：

QString data = ui->textEdit->toPlainText();

将其拆分为 \n（新行）：

QStringList strList = data.split(QRegExp("[\n]"),QString::SkipEmptyParts);

Answer 2

QString QTextStream::readLine(qint64 maxlen = 0)

要阅读文本，您可以使用 QTextStream

    QString text = ui->lineEdit->text();
    QTextStream * stream = new QTextStream(&text , QIODevice::ReadOnly);
    QString line1 =  stream->readLine();
    QString line2 =  stream->readLine();

    qDebug() <<line1;

用于将其添加到向量中

    QString text = ui->lineEdit->text();
    QTextStream * stream = new QTextStream(&text , QIODevice::ReadOnly);
    QVector<QString > lines;
    while (!stream->atEnd())
    {
        lines << stream->readLine();
    }
