GraphicsView doesn't display Pixmap

[grizz]

Hi, I wrote program which has to display an image. I used Pixmap, GraphicsScene and GraphicsView, but it doesn't work... Could you tell me, what's wrong?
QtCreator 2.4.0

@
#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
QPixmap *obraz = new QPixmap("C:\chrome.png");
QGraphicsScene *scena = new QGraphicsScene(this);
scena->addPixmap(*obraz);
QGraphicsView *widok = new QGraphicsView(this);
widok->setScene(scena);
widok->setGeometry(50,50,270,270);
}

MainWindow::~MainWindow()
{
delete ui;
}

Do you even display your widgets in MainWindow?

If you placed it graphically, try calling it from namespace ui.

P.S.: Are you maybe from Slovenia?

This is my main.cpp:

@
#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();

return a.exec();

}
@

When I add text to scene, GraphicsView displays it.

No, I'm not from Slovenia. Greetings from Poland,

You've forgotten to set your QGraphicsView as the central widget.
@
MainWindow::MainWindow(QWidget *parent) : ...
{
...
setCentralWidget(widok);
}

It doesnt't help. Of course I included <QGraphicsView>.

[Jake007]

Declare your QGraphicsView in your class header file.
Like this:

@class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

QGraphicsView *view;
QGraphicsScene *scene;

private:
Ui::MainWindow *ui;
};@

And your .cpp

@MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow)
{
ui->setupUi(this);

view = new QGraphicsView;
scene = new QGraphicsScene;

view->setScene(scene);

this->setCentralWidget(view);
}@

Similar words.
Easily replaced ;).

Still doesn't work :/.

Your image path is also incorrect.
If you are using backslash, you should put \, or you can also put one slash:
"C:/chrome.png"

@ ui->setupUi(this);

view = new QGraphicsView;
scene = new QGraphicsScene;
QPixmap *pix = new QPixmap("C:/pix.png");
scene->addPixmap(*pix);
view->setScene(scene);

this->setCentralWidget(view);
