Put an item on the QGraphicsView

[browser90]

Hi,

I've created via the designer a form with a qgraphicsview in it. Now in my constructor of the mainwindow I would like to place a image in the view, but nothing works. I thought I could do it with ui->nameofview->addPixmapItem but I can't?

It's the first time it do this via the designer so what is wrong with?

In my previous project I did it without the creator with this code:

@
item = new QGraphicsPixmapItem( QPixmap::fromImage(worldImage));
this->addItem(item);
@

but this doens't work :s

Kind regards,

Is the image linked well? I've seen a lot of threads where the filepaths aren't formed well.

Hi,
You need to add a scene to your graphics view and then add the QGraphicsPixmapItem to the scene
e.g

@scene = new QGraphicsScene(this);
ui->graphicsView->setScene(scene);

QImage worldImage("your image path");
item = scene->addPixmap(QPixmap::fromImage(worldImage));@

Where item is QGraphicsPixmapItem and scene is QGraphicsScene.

Try If this works.
