Which event is used to manage the lifecycle of a screen or widget?

The correct choice addresses the lifecycle management of a screen or widget within the OutSystems framework. The "Destroy" event is fundamental because it occurs when the screen or widget is being disposed of, allowing developers to handle any necessary cleanup processes. This can include freeing up resources, stopping ongoing processes, or performing any last-minute operations that should occur before the screen or widget is removed from memory.

Understanding the Destroy event is crucial for maintaining optimal performance and ensuring that there are no memory leaks in the application. For instance, if a widget holds onto resources like timers or event listeners, it is essential to properly manage those when the widget is no longer needed. The Destroy event provides a dedicated point in the lifecycle to implement this cleanup logic.

While the other events play significant roles in the screen’s lifecycle (like initializing actions in the Ready event or rendering in the Render event), they do not serve the same purpose of managing the finalization and disposal that the Destroy event does. This specificity to resource management and lifecycle completion is what makes the Destroy event the correct choice in this context.
