Hello, I'm confused about why the axisclick signal and slot isn't working within my code. Currently, I'm embedding my customplot (with multiple axis rectangles / plots) within a scroll area. If I click on an axis label, an axis, or axis ticks, I see it being selected/highlighted, however, I don't see the signal/slot connecting to a function which is just a print statement. I am able to connect the signals and slots of other mouse event fine, but I don't know why it doesn't for axisClick. Any ideas?

    customPlot->setInteraction(QCP::iSelectAxes, true);

    connect(customPlot, SIGNAL(axisClick(QCPAxis*,QCPAxis::SelectablePart,QMouseEvent*)), this, SLOT(changeYScale(QCPAxis*,QCPAxis::SelectablePart)));
    connect(customPlot, SIGNAL(mouseWheel(QWheelEvent*)), this, SLOT(mouseWheel(QWheelEvent*)));
    connect(customPlot, SIGNAL(mouseDoubleClick(QMouseEvent*)), this, SLOT(mouseDoubleClickEvent(QMouseEvent*)));
    connect(customPlot, SIGNAL(mouseMove(QMouseEvent*)), this, SLOT(mouseMoveEvent(QMouseEvent*)));

Note my customPlot is implemented as a subclass of QCustomPlot (for the time being nothing special yet).

class myQCustomPlot : public QCustomPlot
{
    Q_OBJECT

public:
    explicit myQCustomPlot(QWidget *parent = 0);
    ~myQCustomPlot();

protected:
    void mouseWheelEvent(QWheelEvent *mouse_event);
    void mousePressEvent(QMouseEvent *event);

signals:
    void sendMouseMovement(int&);
    void sendDropEvent(QDropEvent* event);

};
