    Default Trivial graphics view framework coordination problem

    I'm confused with the graphics view framework coordinate system. There is so much information about all kinds of conversions, relations, mappings etc. that I haven't been able to find out solution for my trivial problem.

    The problem is: I want to draw my item so that it fills the view completely. How can I do this after I've scrolled the view? I don't want to use QGraphicsView::fitInView(), I just need to tell in my item's paint function that draw yourself and fill the whole view while doing it.

    you should operate in scene context, because it is not a widget itself, but the content of graphics view. So whatever you do with graphics view (scroll, change it size) the scene remains unchanged. So just make your item fill whole scene (it's bounding rect = 0, 0, scene.width, scene.height). And of course if you want to fill whole graphics view, the scene should cover at least graphics view viewport area.
    I would like to be a "Guru"

    Useful hints (try them before asking):
    1. Use Qt Assistant
    2. Search the forum

    If you haven't found solution yet then create new topic with smart question.
