interwidget

Interwidget refers to the concept and mechanisms by which different software widgets or components can communicate and interact with each other. Widgets are typically small, self-contained applications that perform a specific function and are often embedded within a larger system, such as a web page, a desktop environment, or a mobile application. The ability for these widgets to exchange data, trigger actions in one another, or share state is what constitutes interwidget communication.

This interaction can be achieved through various methods depending on the context. In web development, for instance, interwidget communication might involve using JavaScript event listeners, message queues, or shared data models. For desktop widgets, operating system-provided APIs or inter-process communication (IPC) mechanisms are often employed. Mobile applications utilize similar IPC techniques or platform-specific event buses to enable communication between different UI elements or background services that function as widgets.

The purpose of interwidget communication is to create more dynamic, integrated, and user-friendly experiences. It allows for complex functionalities to be built by combining simpler, reusable components. For example, a weather widget on a dashboard might update a calendar widget to indicate potential weather-related event disruptions, or a stock ticker widget could trigger a notification widget when a specific stock price threshold is met. Effective interwidget communication is crucial for building modular and extensible software systems.
