Qt and overlays

  • I want some user input/output functionality of my application to be displayed as overlay over other applications. Pretty much like they do it in Fraps or Steam I guess. This overlay must also be drawn over applications using DirectX. If it's possible I'd like to do it without hooking other application's functions. Does Qt provide any classes for such task? If not, what would be the best way to achieve this that is compatible with my qt application based on widgets?
