Qt get all QLineEdits' texts within a layout

This is simple structure I have:

QVBoxLayout called switchesLayout_2
 |
 |\_ QHBoxLayout
 |    |
 |    |\_ QLabel
 |     \_ QEditLine
 |
 |\_ QHBoxLayout
 |    |
 |    |\_ QLabel
 |     \_ QEditLine
and so on...

I need to get a text from every QEditLine in switchesLayout_2. I've tried this code:

    for(int i = 0; i < switchesAmount; i++) {
        req += " " + ui->switchesLayout_2->itemAt(i)->layout()->itemAt(1)->widget()->text();
    }
I keep getting: 'class QWidget' has no member named 'text'

What can I do? Thanks!

The easiest way to do this is to use the QObject::findChildren() method on the actual parent widget.

const QList<QLineEdit*> lineEdits = ui->widgetThatHasSwitchesLayout_2->findChildren<QLineEdit*>();
for (QLineEdit *lineEdit : lineEdits) {
    req += " " + lineEdit->text();
}
