Can we connect QPushButton to change values of QSlider?

I have two push buttons labeled with + and - probably, I need to increase and decrease the values of the slider using these push buttons, Please help me to code this function.

Solution

  • First create slots plus() and minus():

    public slots:
    void plus();
    void minus();

    Then connect the clicked signal with the respective slot:

    connect({your minus QPushButton}, SIGNAL(clicked()) , this, SLOT(minus()));
connect({your plus QPushButton}, SIGNAL(clicked()) , this, SLOT(plus()));

    In each slot implement the increase or decrease tasks.

    void {your widget}::plus()
{
    {your slider}->setValue({your slider}->value()+1);
}

void {your widget}::minus()
{
    {your slider}->setValue({your slider}->value()-1);
}
