That was going to be my suggestion as well, and I was working on something last week that needed a transparent overlay to draw across widgets too, so I had this discussion bookmarked that might be helpful? https://stackoverflow.com/questions/19199863/draw-rectangular-overlay-on-qwidget-at-click Sean This message has been scanned for malware by Forcepoint. www.forcepoint.com ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Maybe you can make a window that has no title bar, no borders and is transparent. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
[Interest] Possible to draw between QWindows
Possibly strange question that I have googled a bit for but I may not be using the proper terminology to get the answers that I am looking for. I have a QWidget (say a button) in QWindow "A" and I want to perform a drag action from that QWidget onto another QWidget in another QWindow "B" (So far easy stuff). What I would like to also do while I am dragging is continuously draw a nice stylized line from the current location of the mouse back to the QWidget where the drag started. Is this even possible? I can't seem to figure out if the line would ONLY be drawn inside the QWindows and NOT outside? And if that is the case I would assume that I then need to rely on "native" code for each platform to perform the drawing? If anybody has a working example of this kind of interaction that would also be much appreciated.
