Hi all,
I've been writing an app which displays sequences of images, and allows for the selection of regions of interest in them. Display/playback works like a charm, basically I use a QGraphicsScene/View setup with a QGraphicsPixmapItem in the scene, which is then updated upon receiving the timeout signal of a timer. Pretty basic stuff. Now for selection: one approach would be to subclass either the QGraphicsView or the QGraphicsPixmapItem, overload the mouse events, get the selection coordinates from that for further use and put a QGraphicsRectItem on the scene on top of the selection. Now, I noticed that QGraphicsView already has rubberband selection implemented: when I set the View's DragMode to QGraphicsView.RubberBandDrag, I get a nice rubberband rectangle when I drag the mouse across the View. My problem here is that I can't seem to figure out how to access the selection coordinates of that rectangle. Is there some way of accessing this data? There doesn't seem to be any getDragSelection( ) or some such function, but then how does this work? Do I need to get it from the underlying QGraphicsScene object? Help would be appreciated. Thanks, -- Alex Borghgraef
