    No, that doesnt affect the ScrollBars...

    I thought of sth like connecting the scrollbars to sceneRectangle which is actually impossible..

    You should be able to install an event filter on the dragged object or better yet subclass the item and reimplement its itemChange() method. In there you can get the new item position and adjust the view accordingly.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
