Well, of course we have!

The easiest way is using QThreadPool with a custom QRunnable implementation.

Your QRunnable's run() method would check the necessary values and refresh the UI.

The main UI window should have a QTimer and on a predefined interval (on the QTimer's timeout signal), it would create a new instance of your own QRunnable and make the thread pool execute it.

Note that the thread pool has a static "global instance", so you don't have to create an instance of it, just access the global instance and make that do things for you.
