How to get the QGraphicsLayoutItem clicked in a QGraphicsWidget with QGraphicsLinearLayout

Question

I have QGraphicsLayoutItem placed inside a QGraphicsLinearLayout. This is added to my QGraphicsWidget.

void MyCustomQGraphicsWidget::mousePressEvent(QGraphicsSceneMouseEvent * mouseEvent)
{
    if (mouseEvent->button() == Qt::LeftButton) {
        qDebug() << "clicked inventory";
    }
}

I am having trouble finding a way to get e.g. the index of the item clicked in the layout.

There is no direct way to do it. But you could calculate and index and use the itemAt() method, suppose the mouse y coordinate is mouseY and item height is H. You can write:

int index = mouseY / H; // could be minus some margin
QGraphicsLayoutItem *item = layout.itemAt(index);
