Question

I have some form with fiels, combos etc. I would like to go over through all the widgets on the form and if for example it’s textfield, clear it, something like that:

foreach(QObject *child, this->ui->children())
{
    QLineEdit *txtField = qobject_cast<QLineEdit *>(child);
    if (txtField)
    {
        txtField->clear();
    }
}

The problem is the ui object doesn’t have such property like children and I don’t know how to get the whole collection of children widgets.

Maybe the form object has something like Clear method. It would be the best.

Thanks

Try it.

foreach(QLineEdit *widget, this->findChildren<QLineEdit*>()) {
    widget->clear();
}
