摘要

An image forming apparatus includes an application on a framework that is separated into a core logic portion handling basic processing and a user interface frame portion handling rendering processing and operates; and a controller that executes the application and the framework. The core logic portion is implemented with an application programming interface defined by the framework. The application programming interface includes an after-the-fact notification indicative of that a window displayed by the application is changed to a non-display state as a result that another window is displayed.
