Using QTimer and mouseMoveEvent

[ChrisW67]

Your highlight routine is called once every 500 ms and will do something if the last mouse move event over this widget recorded a position that precisely matches the position of one of your cardIconPlayer objects (whatever they are). That's a precise match on a single pixel position not an area: unlikely to occur, I think you'll agree.

What type are the cardIconPlayer objects?

cardIconPlayer is a QLabel and this is how I set up the icons using pixmap.

void Canvas::setUpPlayerIcons(string *pString)
{
    QPixmap qpx;
    QSize iconSize;
    string str;
 
    for (int i = 0; i < MAXCARDS; i++)
    {
        shadow = new QGraphicsDropShadowEffect(this);
        shadow->setBlurRadius(10);
 
        cardIconPlayer[i] = new QLabel(cardTable);
        str = pString[i];
        qpx = QPixmap(str.c_str());
        iconSize = qpx.size();
        iconSize.scale(190, 276, Qt::KeepAspectRatio);
        QPixmap scaledImage = qpx.scaled(iconSize, Qt::KeepAspectRatio, Qt::SmoothTransformation);
        cardIconPlayer[i]->setPixmap(scaledImage);
        cardIconPlayer[i]->move(20 + 60 * i, 350);
        cardIconPlayer[i]->setGraphicsEffect(shadow);
 
        //playerPixmaps.push_back(scaledImage);
    }
 
}

void Canvas::setUpPlayerIcons(string *pString)
{
    QPixmap qpx;
    QSize iconSize;
    string str;

    for (int i = 0; i < MAXCARDS; i++)
    {
        shadow = new QGraphicsDropShadowEffect(this);
        shadow->setBlurRadius(10);

        cardIconPlayer[i] = new QLabel(cardTable);
        str = pString[i];
        qpx = QPixmap(str.c_str());
        iconSize = qpx.size();
        iconSize.scale(190, 276, Qt::KeepAspectRatio);
        QPixmap scaledImage = qpx.scaled(iconSize, Qt::KeepAspectRatio, Qt::SmoothTransformation);
        cardIconPlayer[i]->setPixmap(scaledImage);
        cardIconPlayer[i]->move(20 + 60 * i, 350);
        cardIconPlayer[i]->setGraphicsEffect(shadow);

        //playerPixmaps.push_back(scaledImage);
    }

}

Just to get this straight. Are you saying I should use QRect instead of QPoint.

I would be inclined to make the QLabels look after their own highlighting when the mouse is over them.

Thank you very much, this was more than thankful. Sorry for the late reply
