Qt provides thread support in the form of platform-independent threading classes, a thread-safe way of posting events, and signal-slot connections across. En resumen, estas.

(QString::number(puntos)); } void game Qt//mingw81_64/include/QtCore La función connect(&Q_OBJECT,SIGNAL,&Q_OBJECT,SIGNAL o SLOT). Contribute to dobeslao/qt-by-example development by creating an account on GitHub.
public slots: void slot(const QString &string) {} void slot(const int integer) {} signals: void signal(const QString &string) {} void signal(const int integer). .
I want to do an UPSERT, this is something like: if (ITEM exists in table) { update ITEM } else { insert ITEM }.
Qt QML, Qt Quick, Qt Quick Controls, Qt Quick Layouts Segnali e slot sono una estensione specifica di Qt alla sintassi C++ QString status = QString{".
Una signal puede conectar otra signal: connect(lineEdit, SIGNAL(textChanged(const QString &)), this, SIGNAL(updateRecord(const QString &)));.
