Can't catch Enter (Return)

[Chaki]

Hello,
I have tried the following code to qDebug something when I click the Enter Button, but nothing happens:

#include <QKeyEvent>
bool MainWindow::eventFilter(QObject* obj, QEvent* event)
{
     if (event->type()==QEvent::KeyPress) {
        QKeyEvent* key = static_cast<QKeyEvent*>(event);
        if ( (key->key()==Qt::Key_Enter) || (key->key()==Qt::Key_Return) ) {
            qDebug()<< "pressed";
        } else {
            return QObject::eventFilter(obj, event);
        }
        return true;
    } else {
        return QObject::eventFilter(obj, event);
    }
    return false;

}
private slots:
    bool eventFilter(QObject* obj, QEvent* event);

Where is the focus when you click the Enter key? Is it on a widget, or do you have a blank main window?

@JonB I am sorry, but I did not quite understand what you mean.
Coul you explain it please?

@Chaki said in Can't catch Enter (Return):

when I click the Enter Button

Do you mean: when I press the enter key?
Or are you using virtual keyboard?

@jsulm i mean the enter key

I have solved it:

    connect(ui->line_Edit, SIGNAL(returnPressed()),ui->btn_Button,SIGNAL(clicked()));

@Chaki
Which is what I suggested: you are pressing the Enter key on a QLineEdit, but you did not tell us that, it helps if you do! :) That line edit has the focus, so the key press will not get sent to the main window....

@JonB Yes, you're right sir. Thanks you your reply
