2. Why I have scollbars in my GraphicsView window ? How to remove them?

QGraphicsView [doc.qt.nokia.com] inherits QAbstractScrollArea [doc.qt.nokia.com] so you can permanently disable the scrollbars by calling the following methods (please note the arguments):

If you want just to set a background color it would be easier to use:

You can add a wiki howto article about this issue here at Qt Developer network :)

You can also reimplement QGraphicsScene::drawBackground [doc.qt.nokia.com]

or take a look also at backgroundBrush [doc.qt.nokia.com]

When I used backgroundBrush (image via QBrush class) image was repeating on all axis. :)…

yes :)
you can reimplement drawbackground like this:

QGV inherits QAbstractScrollArea and the docs there tell you all about the distinction between the viewport and the scroll area. Always a good idea to read the docs for the class(es) that the class of interest publically inherits too.
