JumpToWidget is a Java applet that combines a text input box with a list box so that a user can make a selection from a large list quickly by typing in a substring into the text input box. On each keypress, the List box updates to show only the options that contain the entered substrings. Substrings are separated by spaces in the text input box. Only options which contain every substring are matched, and the comparison is case insensitive by default. This widget attempts to mimic the behaviour of the "Jump To File" feature in Winamp. |

The applet inserts a separator bar in the page, which changes colour continuously. You can specify the initial colour and the speed of the change via parameters. The various parameters of the applet also allow you to specify a lower and upper bound for the colour values and to specify a seed for the random number generator. By giving the same seed (and start colour) to two or more bars, you can ensure that they remain synchronized. The two lower bars on this page are synchronized. |
