Containers have special attributes for accessing UI functionality called Panel Values. Panel Values can be made visible by using a Panel CHOP to observe how the panel component behaves. Each container has its own Panel Values. For instance, if a parent and a child component are both looking for the cursor UV coordinates – the container that the cursor is contained within will be the panel values like insideu and insidev that are updating. Panel values can be used in a variety of ways to create interaction mechanics of UI elements.
