      I guess the eventfilter for your widget or dialog intercepts the event to use it for something else. You should either make sure that you use a widget that will receive that event, or you should use an eventfilter yourself to get it before it is intercepted.

        First, I think so too, but this code is first in the keyPressEvent:
        @void qssTextEdit::keyPressEvent(QKeyEvent *e)
        {
        if (e->key()==Qt::Key_Enter)
        {
        qDebug() << "1";
        emit makeIndent();
        }
        //Next code
        @
        And there are no any key filters in program. Code worke wright if instead "Enter" use Escape or Tab in example

          eventfilter for your widget or dialog

          are you using a QDialog? Or which type of widget do you use?
          Enter is often caught for special actions, in dialog, e.g. to activate the default button.

              Do you use the QPlainTextEdit within a QDialog? The QDialog catch the Enter key. So do you have to install a eventFilter.

                  Do you want Key_Enter or Key_Return?

                  Key_Enter usually is the small enter key on the keypad.
