Issue connecting member function to signal

[mortbopet]

I'm having a problem with connecting a custom button class, which inherits from QPushButton.

I want to connect the clicked() signal, (which should be emitted on click, since the parent is QPushButton) to a member function of the class. I've had success with implementing the mousePressEvent function, inside the class.

#include "looperbutton.h"
#include <QtGui>
#include <QApplication>

LooperButton::LooperButton(QWidget *parent)
    : QPushButton(parent)
{
    this->state = 0;
    connect(this, SIGNAL(clicked()), this, SLOT(clickedButton()));
    setFixedSize(100,100);
}

void LooperButton::clickedButton()
{
    QApplication::beep();
    setText("clicked");
}

void LooperButton::mousePressEvent(QMouseEvent *e)
{
    //This works
}

for completion, here is the header:

#ifndef LOOPERBUTTON_H
#define LOOPERBUTTON_H

#include <QPushButton>

class LooperButton : public QPushButton
{
    Q_OBJECT
protected:
    void enterEvent(QEvent *event);
    void leaveEvent(QEvent *event);
    void mousePressEvent(QMouseEvent *event);
    void mouseReleaseEvent(QMouseEvent *event);


private slots:
    void clickedButton();

private:
    int state;

public:
    LooperButton(QWidget *parent = 0);
    ~LooperButton();
};

#endif // LOOPERBUTTON_H

Any suggestions?

Are you completely overriding mousePressEvent()? You probably have to include

QPushButton::mousePressEvent(event);

in your mousePressEvent to get the standard QPushButton behavior (e.g., emitting the clicked() signal).

Perfect, that did the trick.
Thank you very much.
