| As one can see, access to all objects which comprise GUI possible at all times. We, of course, have the UI component, we can access the implementation component, and we can access the extension/technology component. Theoretically, we could also swap them at runtime, but in [[https://sourceforge.net/projects/jvx/|JVx]], this is limited to the construction of the object to greatly reduce the error potential and complexity of the framework code. | As one can see, access to all objects which comprise GUI possible at all times.

| - | We are setting a new UIResource (an ''%%UIPanel%%'') in the constructor (at line #5) which is to be used by the ''%%UIComponent%%''. In this case it is not an Implementation, but another UI component, but that doesn’t matter because the UIResource only must implement the expected interface.
