Did you check the bug report system ?

If there's nothing there, please prepare a minimal compilable example (which sometimes allows you to also find errors in your code) that reproduces the problem. Once it's done you should open a new bug report with it.

@#include <QApplication>
#include <QGraphicsScene>
#include <QGraphicsTextItem>
#include <QGraphicsView>
#include <QLayout>
#include <QMainWindow>

int main(int argc, char argv[])
{
QApplication a(argc, argv);
QMainWindow window = new QMainWindow();
window->setFixedSize(200, 200);

QGraphicsScene* scene = new QGraphicsScene(window->rect(), window);
QGraphicsTextItem* ti = new QGraphicsTextItem("text");

ti->setTextInteractionFlags(Qt::TextEditorInteraction);
ti->setCacheMode(QGraphicsObject::ItemCoordinateCache);
ti->setPos(100, 100);

QGraphicsView* view = new QGraphicsView(window);
view->setScene(scene);
scene->addItem(ti);

window->layout()->addWidget(view);
view->resize(window->size());

window->show();

return a.exec&#40;&#41;;

You mean like this:
@QGraphicsTextItem* ti = new QGraphicsTextItem("text1\ntest2\ntest3");@

This does work, or do I not understand your question
