UIGeometry Class Reference

Generated geometry class. All widgets have one. This class separates the geometry creation into several steps, making it possible to perform actions selectively depending on what has changed. For example, the widget doesn't need to be rebuilt unless something actually changes, so its geometry can be cached. Likewise, the widget's transformed coordinates only change if the widget's transform moves relative to the panel, so that can be cached as well. In the end, using this class means using more memory, but at the same time it allows for significant performance gains, especially when using widgets that spit out a lot of vertices, such as UILabels.
