MainWindow::MainWindow(QWidget *parent): QMainWindow(parent), ui(new Ui::MainWindow)
{ui->setupUi(this);QWidget::installEventFilter(this);
}bool MainWindow::eventFilter(QObject *watched, QEvent *event){if(event->type()==event->KeyPress){QKeyEvent *keyEvent = (QKeyEvent *)event;if(keyEvent->key() == Qt::Key_S && (keyEvent->modifiers() & Qt::ControlModifier)){qDebug()<<"Enter + S";return true;}}return false;
