Qt counting error

[premroxx]

I have 2 push button, one for increment & the other for decrement & a label to display result. I use this setup in 2 different places. But in some odd cases, the counter seems to be increasing at the rate of 16(0,16,32..etc). I'm not sure why this is happening. What am i doing wrong here. Is there an easier/simple way of doing this?

int count2; (declared in a .h file, as a public variable)
 
    connect(this->ui->pb_inc, SIGNAL(clicked()), this, SLOT(inc()));
    connect(this->ui->pb_dec, SIGNAL(clicked()), this, SLOT(dec()));
 
void MainWindow::inc()
{
    count2=count2+1;
    this->ui->label_count->setText(QString("%1").arg(count2));
}
 
void MainWindow::dec()
{
    count2=count2-1;
    if(count2<=0) count2=0;
    this->ui->label_count->setText(QString("%1").arg(count2));
}

int count2; (declared in a .h file, as a public variable)

    connect(this->ui->pb_inc, SIGNAL(clicked()), this, SLOT(inc()));
    connect(this->ui->pb_dec, SIGNAL(clicked()), this, SLOT(dec()));

void MainWindow::inc()
{
    count2=count2+1;
    this->ui->label_count->setText(QString("%1").arg(count2));
}

void MainWindow::dec()
{
    count2=count2-1;
    if(count2<=0) count2=0;
    this->ui->label_count->setText(QString("%1").arg(count2));
}

Does this help?

connect(this->ui->pb_inc, SIGNAL(clicked()), this, SLOT(inc()),Qt::UniqueConnection);
connect(this->ui->pb_dec, SIGNAL(clicked()), this, SLOT(dec()),Qt::UniqueConnection);

connect(this->ui->pb_inc, SIGNAL(clicked()), this, SLOT(inc()),Qt::UniqueConnection);
connect(this->ui->pb_dec, SIGNAL(clicked()), this, SLOT(dec()),Qt::UniqueConnection);
