## Description

Every object property of every GladeWidget in every GladeProject has a GladeProperty to interface with, GladeProperty provides a means to handle properties in the runtime environment.

A GladeProperty can be seen as an instance of a GladePropertyClass, the GladePropertyClass describes how a GladeProperty will function.
