I would connect the finished signal to a class that counts the # of signals received and emits quit() when it hits the expected count.
Something like this:
class EmitIfCountReached : public QObject
{
Q_OBJECT
public:
EmitIfCountReached( int expectedCount, QObject* parent = nullptr) : m_expected(expectedCount), m_count(0), QObject(parent) {}
signals:
void finished();
protected slots:
void increment() {
m_count++;
if (m_count >= m_expected) {
emit finished();
}
}
protected:
int m_count;
int m_expected;
};
