Handling longpress.

Hi
I want to create longpress of a painted shape, how it should done?
Waiting for your reply.

What is a painted shape, I mean what is the Qt type used for it

If your painted shape if of type QWidget then, it can be this way

Code:

---

void MyWidget::mousePressEvent(QMouseEvent* event)
{
    long_press_timer = startTimer(4000); // 4 second Longpress
}
 
void MyWidget::mouseReleaseEvent(QMouseEvent* event)
{
    long_press_timer = 0;
}
 
void MyWidget::timerEvent(QTimerEvent* event)
{
    if(long_press_timer  == event->timerId())
    {
        // processes long press
    }
    long_press_timer  = 0;
    killTimer(vent->timerId());
}

If your shape is of type QGraphicsObject, it is similar, implement these

Code:

---

void MyGraphicsObject::mousePressEvent(QGraphicsSceneMouseEvent* event);
void MyGraphicsObject::mouseReleaseEvent(QGraphicsSceneMouseEvent* event);
void MyGraphicsObject::timerEvent(QTimerEvent* event);
