45 | * The gui filter facility gives the user an easy to use | |
46 | * basic interface to construct and modify at will a filter | |
47 | * expression. User may either decide to write it himself in | |
48 | * expression text entry or add simple expressions using the | |
49 | * many choices boxes. | |

7e7af7f2 | 52 | * my desktop misses some function of the newer |
da2e1bfb | 53 | * gtk+ api. For the time being, I'll use the older api |
7e7af7f2 | 54 | * to keep compatibility with most systems. |
