Отслеживание клика по QLabel

Как отследить клик по QLabel. Есть вариант через mouseevent, может есть слот какой?

Нет. На самом деле нет никакого сигнала или слота, чтобы отследить клик по QLabel. Единственное верное решение - это наследоваться от QLabel, переопределить один из методов mouseevent`ов и оттуда испускать свой сигнал clicked()

#ifndef CUSTOMLABEL_H
#define CUSTOMLABEL_H

#include <QLabel>
#include <QMouseEvent>

class CustomLabel : public QLabel
{
    Q_OBJECT
public:
    explicit CustomLabel(QWidget* parent = nullptr) : QLabel(parent)
    {

    }

    void mousePressEvent(QMouseEvent* event) override
    {
        QLabel::mousePressEvent(event);
        emit clicked();
    }

signals:
    void clicked();

public slots:
};

#endif // CUSTOMLABEL_H
