Displaying an image

[seltra]

i want to display a car photo.
after loading, user can move the car by pressing keys on keyboard.
when he press "up arrow", car will move upwards.
which methos should i use to show the photo. Qlabel.setpixmap??
The code below shows the image on a new widget, but i want to show it on my mainwindow page.
What should i do?
Thank you

void MainWindow::showIt()
{
    QLabel *image = new QLabel();
    image->setPixmap( QPixmap( "car.jpg" ) );
    image->show();
    update();
}

void MainWindow::showIt()
{
    QLabel *image = new QLabel();
    image->setPixmap( QPixmap( "car.jpg" ) );
    image->show();
    update();
}

To copy to clipboard, switch view to plain text mode 

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

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

Now i can change pixmap of Label with the code below

ui->label->setPixmap( QPixmap( "car.jpg" ) );

ui->label->setPixmap( QPixmap( "car.jpg" ) );

but for this code i need to create a QLabel in forms window.
So i can manipulate it's Pixmap property.

But how can i create a Label in centralwidget after the run of the program?
thank you.

QLabel *label = new QLabel( "Push me" );
    ui->[name of layout You want to place QLabel]->addWidget( label );

QLabel *label = new QLabel( "Push me" );
    ui->[name of layout You want to place QLabel]->addWidget( label );
