Your program uses class CL_GUI_ALV_GRID to generate a classic ALV Grid Control. What is needed to react to a user double-clicking a row in the ALV Grid?

To enable the program to respond to a user double-clicking a row in the ALV Grid, it is essential to establish a connection between the event that generates the double-click and the handler that will process this event. The selection of a handler class is vital in this context.

In this scenario, the handler class contains methods that are designed to manage various events emitted by the ALV Grid, including the double-click event. The handler class encapsulates the logic needed to process user interactions, making it a necessary component for effectively managing user actions within the grid.

In addition to the handler class, proper registration with the ALV Grid is required to ensure that the double-click event is linked to the appropriate handling method. This would involve using a specific statement to set up the connection between the event and the handler. Thus, the handler class serves as the foundation for encapsulating the necessary logic, ensuring that when the user interacts with the grid, the corresponding method is executed appropriately.
