title: How to data-bind a label text to an underlying object's property?
body: <p>We're building a Qt4.8/C++ application (no QML) that will run on an embedded ARM device. This device constantly receives values of a lot of datapoints that need to be held in an object. Now I want to bind UI elements to specific properties of this model object in order to automatically always show the current and up-to-date values in the UI.</p>
  
  <p>Is there a mechanism in Qt that I can use? Or do I have to keep track of any changes and manually update the UI? It would be great if someone could give me a very basic example on how to, for example, data-bind a label text to a double value property of an object. Thanks in advance!</p>
