Hi there, I am trying to implement an "oversight" view, that is a small view that always display the full scene (plus a little margin) and draw a red rectangle that correspond to the scene rect that is displayed on the screen by the "main" view, my feeling is that I have to use the viewport of the qgraphicsview, but I can't find out how to achieve this. I tried naively to use mainview->sceneRect() but it return the scene rect that is accessible within the view (including parts that will be displayed when moving the scroll bars).
As usual, as I'm writing this email and at the same time keep reading the doc and testing stuff, I think I found it!;) QTransformt=mMainView->viewportTransform(); QRectF r = mMainView->viewport()->rect(); r = t.transposed().mapRect(r); It seems to do the job, not sure it's pixel perfect, but it seems good enough for me. If anyone has comment or advice on doing this kind of things, I'm still interesting! My next step will be to forbid scene interaction within the "oversight" view, but still allowed the user to resize the main view area (the red rectangle) within the oversight view.
