QGraphicsScene segmentation fault

[maxpower]

I have the following code


#include <QGraphicsScene>
#include <QMessageBox>
#include "proFootballOnline.h"
//
ProFootballOnline::ProFootballOnline( QWidget * parent, Qt::WFlags f)
: QMainWindow(parent, f)
{
setupUi(this);
}

void ProFootballOnline::Init ()
{

}
void ProFootballOnline::on_initPB_clicked()
{
QGraphicsScene scene;
scene.addText("Bob");
//scene.setItemIndexMethod(QGraphicsScene::NoIndex);
//fieldGV->setBackgroundBrush(Qt::green);
fieldGV->setScene(&scene);
fieldGV->update();
}


When the program runs and the initPB is clicked, the program closes a does a core dump. I ran it through a debugger and, depending on what I try to do with the scene, faults on various things (setBackground, setItemIndexMode). The fieldGV is a QGraphicsView I have on my main window. Any ideas on what is causing the crash? If I place a QMessageBox at the end of the slot, i can see the contents of fieldGV update properly but closing the box sets off the core dump.

Your problem is that scene is allocated on the stack, e.g. you do not write ... *scene = new... This means that scene is automatically deleted as soon as you leave the slot.
