    The QGraphicsScene is destroyed when falling out of scope if you create it on the stack.

    Not sure about KMainWindow, but in a normal QMainWindow subclass you could do something like:

    Qt Code:
    1. MainWindow::MainWindow(QWidget *parent)
    2. : QMainWindow(parent)
    3. {
    4. QGraphicsScene *scene = new QGraphicsScene(0, 0, 1366, 768, this);
    5. scene->addText("Hello, world!");
    6. view->setScene(scene);
    7. setCentralWidget(view);
    8. }
    To copy to clipboard, switch view to plain text mode

    QGraphicsView *view=new QGraphicsView(this);
    QGraphicsScene *scene=new QGraphicsScene(0, 0, 1366, 768);

    worked
