Detailed Description

A complex component combining a grid and form view with CRUD capabilities.

The GridView supports both inline editing and form-based editing of grid rows, switching between a grid display and a detailed form view. It also provides buttons for adding, editing, deleting, saving, and canceling changes. Listeners can be registered to react to CRUD events.

Implements ActionListener to handle button actions and RowDoubleClickListener to handle double-click events on grid rows.
