About Interactors and Accelerators

IlvZoomOutAccelerator is a custom accelerator, that is, a subclass of IlvAccelerator. An accelerator is a class that listens to a specific key event in the manager. All input events are handled by means of interactors or accelerators. For information about how to treat events in a manager, see Handling Events. The following code examples show how to handle user events:

• global view interactor example
• local object interactor example
