QGraphicsLineItem + setAcceptHoverEvents

[NoRulez]

Hey @all,

i'm trying to get the hover effect working for my QGraphicsLineItem object.
I have subclassed the QGraphicsLineItem class, and in the constructor i wrote:

setAcceptHoverEvents(true);

setAcceptHoverEvents(true);

To copy to clipboard, switch view to plain text mode 

I implemented the protected functions like below:

void Arrow::hoverEnterEvent(QGraphicsSceneHoverEvent * event) {
    //QGraphicsLineItem::hoverEnterEvent(event);
    qDebug() << "void Arrow::hoverEnterEvent(QGraphicsSceneHoverEvent * event)";
    pen().setColor(QColor(204, 0, 255, 76));
}
 
void Arrow::hoverLeaveEvent(QGraphicsSceneHoverEvent * event) {
    qDebug() << "void Arrow::hoverLeaveEvent(QGraphicsSceneHoverEvent * event)";
    pen().setColor(myColor);
}

void Arrow::hoverEnterEvent(QGraphicsSceneHoverEvent * event) {
    //QGraphicsLineItem::hoverEnterEvent(event);
    qDebug() << "void Arrow::hoverEnterEvent(QGraphicsSceneHoverEvent * event)";
    pen().setColor(QColor(204, 0, 255, 76));
}

void Arrow::hoverLeaveEvent(QGraphicsSceneHoverEvent * event) {
    qDebug() << "void Arrow::hoverLeaveEvent(QGraphicsSceneHoverEvent * event)";
    pen().setColor(myColor);
}

To copy to clipboard, switch view to plain text mode 

But when i come over the line with my mouse pointer the functions doesn't be executed?

What i'am doing wrong? Can anybody help me.
