| 2 * | |
| 3 * This is the demo program for the animated menu. We will use to test the MBAF API. | |
| 4 * We need to have group item1-item9 in the SVG file. Initially, we will show | |
| 5 * item1-item8 only. When a up/down key is pressed, we will draw the next item in item9 and | |
| 6 * add two words to move item1-item9 smoothly. The first word move items to the 3/4 position | |
| 7 * fastly. The second will move it from 3/4 to the final position slowly to make retard effect. | |
| 8 * | |
| 9 * If we press another key before the second words finish, we will delete the word and replace | |
| 10 * it with a word to move it fastly to the final position and then we will repeat the procedure | |
| 11 * to add another two words to move it to the next position. | |
