C++ Question

C++/Qt Global Hotkeys

I'm working on an application, which I need to run in the background and run a function when a certain combination of buttons is pressed. I kind of understand that this requires a platform-specific API call (WIN32, X11, etc.), but I don't really know how to start. Also, is there a multi-platform way to achieve this? I really need this to work on Windows, Linux, and OSX.

Answer

To summarize:

  1. The Qt Event System may be an option (with some help on system/desktop manager level)
  2. Qxt Library (not longer maintained)
  3. Or this project UGlobalHotkey

. 2. seems the best option so far. Though it is not longer maintained it currently works with Qt5.
