Intercept key on QLineEdit

[fermatqt]

hi!

I need to intercept the F8 key when I'm on a QLineEdit.
it's possible?

Use event filters for line edit.

ok, i did something like this, and seems to work:

bool ForzaTestataContab::eventFilter(QObject *obj, QEvent *event) {
    QKeyEvent *key = static_cast<QKeyEvent *>(event);
    if (obj == editCondPag && event->type() == QEvent::KeyPress && key->key() == 16777271) {
        HelpWindow *help = new HelpWindow("get_cond_pag_all.txt");
        help->show();
    } else if (obj == editVett1 && event->type() == QEvent::KeyPress && key->key() == 16777271) {
        HelpWindow *help = new HelpWindow("get_vettori.txt");
        help->show();
    }
    return QObject::eventFilter(obj, event);
}

tks!!

My inputs. Don't compare key with big number. Check qt::key_f8. It is good practice.
