Getting a string from QGraphicsSimpleTextItem from QGraphicsItem foreach loop?

I am making an image annotation system Using qrect and Simple text items.

I am trying to store the string values from the QGraphicssimpletext items into a JSON file to save and load the annotation boxes. The rectangles work fine but I cannot understand how to get a string value. This is the foreach I am trying to loop through for each item, and as the text items are children of the rectangles the position does not matter.

foreach(QGraphicsItem* item, items())
{
    arrayPosX.push_back(item->x());
    arrayHeight.push_back(item->boundingRect().height());
    arrayWidth.push_back(item->boundingRect().width());
    arrayPosY.push_back(item->y());
    arrayAnnotation.push_back(item->?);
}

Both the simple text and rect items are added to the scene using 

itemToDraw = new QGraphicsRectItem;
this->addItem(itemToDraw);
simpleTextToDraw = new QGraphicsSimpleTextItem;
this->addItem(simpleTextToDraw);

I would simply like to know how I could get the string values from the simple text item as to allow saving and loading of both strings and boxes, not just boxes which the current system can do.

You have to cast and verify that the pointer is not null:

// ...
arrayPosY.push_back(item->y());
if(QGraphicsSimpleTextItem* text_item = qgraphicsitem_cast<QGraphicsSimpleTextItem *>(item)){
    arrayAnnotation.push_back(text_item->text());
}
