| 15 |  |  |  |  |  |  |  | 
| 16 |  |  |  |  |  |  | This module provides some helper functions for the container UI elements of | 
| 17 |  |  |  |  |  |  | the minimal fallback UI. |

| 19 |  |  |  |  |  |  | =head1 DESCRIPTION | 
| 20 |  |  |  |  |  |  |  | 
| 21 |  |  |  |  |  |  | The documentation of this module is only intended for developers of the | 
| 22 |  |  |  |  |  |  | package itself. | 
| 23 |  |  |  |  |  |  |  | 
| 24 |  |  |  |  |  |  | All functions of the module will be included as second "base class" (in | 
| 25 |  |  |  |  |  |  | C<@ISA>) like (and instead of) C>. |

| 33 |  |  |  |  |  |  | Container elements may contain a reference to an array containing only the | 
| 34 |  |  |  |  |  |  | references to the active UI elements (those that are accessible, basically | 
| 35 |  |  |  |  |  |  | everything not just a simple text output). |
