class Label: public QWidget
{
public: 
    virtual void mousePressEvent(QMouseEvent * event) Q_DECL_OVERRIDE
    {
        if( m_leftArrowArea.contains( event->pos() ) )
        {
            //Handle left arrow action
        }
        else if( m_rightArrowArea.contains( event->pos() ) )
        {
            //Handle right arrow action
        }
    }


private:
    QRect m_leftArrowArea;
    QRect m_rightArrowArea;
}

On click you can get the relative co-ordinates of the mouse using which you can calculate the distance of mouse click from the left side of the image, using which you can distinguish click on different parts of the image.
