Trait QDataBinder

Trait QDataBinder The QDataBinder trait encapsulates the functionality of data binding for multiple controls that would like to make use of it. Data binding lets you only recall data during draw time, thus saving space, because the data is not saved with the formstate. Controls that use this will have to be sure to unload the data after drawing as needed.

There are a couple of modes of this. A legacy mode use strings to record the function names. The more modern way uses an array as a callable.
