How can i set buttonbox 3 second pressing? For example i try to change label. But i need 3second pressing the button.

You have to implement your own onMousePressEvent() and onMouseReleaseEvent() with starting QTimer.

My code:

in header:

private:
    Ui::MainWindow *ui;
    QTimer *counter;

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QTimer>



MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{    
    ui->setupUi(this);
    QTimer *counter = new QTimer(this);
    connect(counter,SIGNAL(timeout()),this,SLOT(update());
}

MainWindow::~MainWindow()
{

    delete ui;
}

void MainWindow::on_pushButton_pressed()
{
    counter->start(1000);
}

void MainWindow::on_pushButton_released()
{
    counter->stop();
    if(counter>=3000){
        ui->label->setText("ggwp");
    }
}

I guess counter is not used like that. How can i use ?

You're welcome.

#ifndef CBUTTON_H
#define CBUTTON_H

#include <QPushButton>
#include <QTimer>

class cButton : public QPushButton
{
    Q_OBJECT
public:
    explicit cButton(QWidget * parent = 0) :  QPushButton(parent){
    cTimer.setSingleShot(true);
    connect(&cTimer, &QTimer::timeout, this, &cButton:longPressed);
}
    void setTimeout(int mSec){mSeconds =mSec;}
signals:
    void longPressed();

protected:
    virtual void mousePressEvent(QMouseEvent *e)Q_DECL_OVERRIDE{
        QPushButton::mousePressEvent(e);
        cTimer.start(mSeconds);
    }

    virtual void mouseReleaseEvent(QMouseEvent *e)Q_DECL_OVERRIDE{
        QPushButton::mouseReleaseEvent(e);
        cTimer.stop();
    }

private:
    QTimer cTimer;
    int mSeconds = 3000; 
}
#endif // CBUTTON_H

If you make code in your style...

in header:

#include <QTimer>
[...]
private:
    Ui::MainWindow *ui;
    QTimer counter;
[...]

in cpp:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{    
    ui->setupUi(this);

    counter.setSingleShot(true);
    connect(&counter, &QTimer::timeout, [=]{
        ui->label->setText("ggwp");
    });

}

void MainWindow::on_pushButton_pressed()
{
    ui->label->setText("");
    if (counter.isActive())
        counter.stop();
    counter.start(3000);
}

void MainWindow::on_pushButton_released()
{
    if (counter.isActive()) {
        counter.stop();
        ui->label->setText("Opps!");
    }
}

        counter.stop();
        ui->label->setText("Opps!");
    }
}

It works. I think my style is very easy for understanding. I try to make somethings but i can't find any resources. So i use here. Thank you.

Welcome~
I agree with you. However, I think the method proposed by @J-Hilk is better depending on the concept of code reusability and OOP.
