This behaviour is available as a direct property to QLineEdit since Qt 5.2:

https://qt-project.org/doc/qt-5/qlineedit.html#clearButtonEnabled-prop

QLineEdit *edit = new QLineEdit(this);
edit->setClearButtonEnabled(true);

You can add a custom QAction with your self-defined icons to the QLineEdit:

https://qt-project.org/doc/qt-5/qlineedit.html#addAction

QLineEdit *edit = new QLineEdit(this);
QAction *action =
    edit->addAction(QIcon("/path/to/icon"), QLineEdit::ActionPosition::LeadingPosition);
connect(action, &QAction::triggered, this, &ThisObject::doSomething);
