Preventing Enter key from triggering OK in QButtonBox in particular QLineEdit QButtonBox

I have a Dialog which has some widgets such as QComboBox, QSpinBo开发者_开发知识库x and some QLineEdit. At the bottom of the widget, I have a QButtonBox. Clicking enter in any one of the widgets will trigger the accepted() slot for the QButtonBox. However, I'd like to disable this automated action in one of the QLineEdits. So, pressing Enter key in one of the QLineEdit wouldn't trigger the accepted() slot for the QButtonBox. How can I do that?

I suggest you to install an EventFilter. Something like:

 bool FilterObject::eventFilter(QObject *object, QEvent *event)
 {
     if (object == target && event->type() == QEvent::KeyPress) {
         QKeyEvent *keyEvent = static_cast<QKeyEvent *>(event);
         if (keyEvent->key() == Qt::Key_Enter) {
             // Special key handling
             return true;
         } else
             return false;
     }
     return false;
 }
