Click and longClick in the same button

[ivanicy]

Hello! I have a QPushButton which has three slots, clicked, pressed and released. This is my code:

void MainWindow::on_button_clicked()
{
    qDebug() << "Click pressed";
}

void MainWindow::on_button_pressed()
{
    m_pTimer->start(2000);
}

void MainWindow::on_button_released()
{
    m_pTimer->stop();
}

void MainWindow::longClick() {
    qDebug() << "Long click pressed";
}

Well, I want that, when the timer has a timeout (longClick()), ignore de click event. How can I do it? Thank you very much!

@ivanicy Hello,

Here is a possible solution:

//widget.h
quint64 m_pressedTime = 0;

//widget.cpp
Widget::Widget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Widget)
{
    ui->setupUi(this);

    connect(ui->pushButton, &QPushButton::pressed, [&]{ m_pressedTime = QDateTime::currentMSecsSinceEpoch(); });
    connect(ui->pushButton, &QPushButton::released, this, &Widget::released);
}

void Widget::released()
{
    quint64 now = QDateTime::currentMSecsSinceEpoch();
    if(now - m_pressedTime > 2000){
        qDebug() << "long clicked";
    } else {
        qDebug() << "clicked";
    }
    m_pressedTime = 0;
}

@Gojir4 That works fine but, I need a small improve. I need that when this two seconds pass, do the action, not on the release event.

Thank you for your time!

@ivanicy I knew I should have kept the timer...

Updated using timer

//widget.h
    QTimer m_longClickTimer;

//widget.cpp
Widget::Widget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Widget)
{
    ui->setupUi(this);

    m_longClickTimer.setSingleShot(true);
    connect(ui->pushButton, &QPushButton::pressed, [&]{ m_longClickTimer.start(2000); });
    connect(ui->pushButton, &QPushButton::released, this, &Widget::released);
    connect(&m_longClickTimer, &QTimer::timeout, this, &Widget::longClickTimeout);
}
void Widget::released()
{
    if(m_longClickTimer.isActive()){
        qDebug() << "clicked";
        m_longClickTimer.stop();
    }
}

void Widget::longClickTimeout()
{
    qDebug() << "long clicked";
}

@ivanicy

Start a single shot timer with a 2 sec timeout, every time the button was pressed. If timer fires at 2s and button still pressed, start your action, else reset the time (on release also reset your time).
