Getting textItem from a the QGraphicsView.

[jkwok678]

The behaviour i want is when a user clicks on the screen if there isn't already a QGraphicsTextItem there, the user will add one there, but if there already is, allow for it to be edited.

if (!drawnLayout->checkTextExists(finalX,finalY)) {
                    QString readableBit = "Enter text: ";
                    std::shared_ptr<Text> text(new Text(*canvasChosen, finalX, finalY, readableBit));
                    drawnLayout->addText(text);
                }
                else
                {
                    foreach(QGraphicsItem *item, items())
                    {
                        if (item->x() == finalX)
                        {
                            if (item->y()==finalY){
                                item->setTextInteractionFlags(Qt::TextEditorInteraction);
                                item ->setFlags(QGraphicsItem::ItemIsSelectable | QGraphicsItem::ItemIsFocusable | QGraphicsItem::ItemIsMovable);
                                item->setFocus();
                            }
                        }
                    }
                }

The logic at the if statement is right I think, but I'm stuck on how to do the part in else, because the 'item' needs to be a QGraphicsTextItem to be able for me to edit and save.

QGraphicsTextItem textItem = qobject_cast<QGraphicsTextItem*>(item);
if (textItem) {
    // textItem is a QGraphicsTextItem
}

Hi
Is qgraphicsitem_cast not to be used if one uses the user type ID ? / custom class.
