Did you search at all before posting this? I actually tried editing your title to correct it, when it said that a question with the exact same title exists: http://stackoverflow.com/questions/3624733/how-to-make-a-qgraphicstextitem-clickable — Mitch, Jul 04 '14 at 14:37

So if you add `text->setTextInteractionFlags(Qt::TextBrowserInteraction);`, it doesn't work? — Mitch, Jul 04 '14 at 15:15

Not quite sure whether you needed your text item to be "editable" - see Mitch's comment...

It seems that you need your item to be "clickable" - then all you need are some flags:

text->setFlags(QGraphicsItem::ItemIsSelectable | QGraphicsItem::ItemIsFocusable);
