| """ | |
| Changes added by ricardj: | |
| -Import now done with tk prefix instead of using the wildcard import. | |
| -Down movement starts at zero. | |
| -Now up and down movement is cyclic. | |
| -Added return function in order to use the autocomplete-listbox as a tag selector. With out leaving the keyboard the user is going to be able to write with autocomplete and select some tags fast. | |
| -List height reimplemented to make it adapt to the number of matching words. It would be great to define a max listbox length and not to fix the listbox length from the begining. | |
