Can I set the time when toolTip appears on QGraphicsItem?

Good afternoon. The toolTip on QGraphicsItem appears after about one second. Can this value be changed? If so, how?

Probably you can give a try using

void QToolTip::showText(const QPoint &pos, const QString &text, QWidget *w, const QRect &rect, int msecDisplayTime)

You need to handle the QEvent::ToolTip in your event handling code. I lifted that piece of code from documentation. And below it is. (Note: I did not test this.)

//CREATE AN EMPTY RECT
QRect rect();

//HANDLE THE QEvent::ToolTip
if (event->type() == QEvent::ToolTip) {
        QHelpEvent *helpEvent = static_cast<QHelpEvent *>(event);
        int index = itemAt(helpEvent->pos());
        if (index != -1) {

        //HERE YOU CAN CONTROL TIME.
            QToolTip::showText(helpEvent->globalPos(), shapeItems[index].toolTip(), nullptr,rect,<<TIME YOU WANT TO SET>>);
        } else {
            QToolTip::hideText();
            event->ignore();
        }

        return true;
    }
    return QWidget::event(event);
}
