And on the focus passing between components (like fields in the same form) for example after writing a code in a field, pressing <Enter> or when the data inside the field has been automatically validated, will it be possible with an event to trigger, right ?
Components transfer focus on Tab key press. To support your use case, you could attach a key listener to the parent container and call transferFocus() on the currently focused component when the Enter key is pressed.
And the same for example also writing data in a Table ... where <Enter> for example goes to the next cell or row in the table (after optional validation of cell contents).
You can write a custom cell editor that will do this.
