| current version: 1.4 |
| |
| version history: |
| 0.99 (2004-10-26) |
| initial version |
| |
| 1.0 (2005-09-15) |
| allow undefined values in callback function for selectionlists that need not react on changes (suggestion by Bruce Rindahl) |
| allow selectionlist to be placed in a transformed group |
| now also works in MozillaSVG (due to changes in mapApp.js) |
| |
| 1.1 (2005-09-28) |
| removed "string" option in functionToCall (not important any more). function and object should be good enough |
| timer object from http://www.codingforums.com/showthread.php?s=&threadid=10531 is now used; attention: you need to link this script as well! |
| due to the new timer object we can now also mouse down and scroll more than one entry until we mouseup again, previously one had to click for forwarding each individual element |
| |
| 1.2 (2005-10-24) |
| removed style attributes and replaced them with individual XML attributes |
| initial tests on Opera 9 TP1, it seems to work except for the scrolling - due to a mouse-move event bug |
| |
| 1.2.1 (2005-02-07) |
| upgraded the documentation and fixed documentation errors |
| |
| 1.2.2 (2006-02-16) |
| added option to open selectionList to the top of the original box, this is useful for layouts where the selectionList is at the bottom of a page |
| added option to always put the selectionList on the top of it's parent group after activation in order to force the geometry to be on the top of all other geometry within the same group |
| improved background rectangle: these are now two rectangles: one on the bottom for the fill, one on the top for stroking |
| tested with Opera 9 TP2, works now fine, except keyboard input |
| |
| 1.2.3 (2006-02-21) |
| removed dependency on replaceSpecialChars (in file helper_functions.js) as this is not really needed in a true utf8 environment. |
| improved key event handling. People can now enter more than one key (within one second for each consequent key) and the list will jump to entries that match the keys; key events now also work in opera 9+ - however they sometimes collide with keyboard shortcuts. |
| |
| 1.3 (2006-03-11) |
| changed parameters of constructor (styling system): now an array of literals containing presentation attributes. Not hardcoded in selectionList.js anymore. Added check for number of arguments. |
| |
| 1.4 (2006-07-18) |
| added additional constructor parameter "parentNode", changed groupId to id, added methods .resize(width) and .moveTo(x,y) |
| improved scrolling (now also possible outside of the scrollbar, once the mouse is down) |
