Better than using css since: - theme.event.track.height & theme.event.tape.height need to work with each other. - It is easier and clearer to set both in the same place (the theme), rather than - one in the theme and one in the css. This is a breaking change if you were - setting the height in the css. People were having problems with this in the - mailing list. - - Further note about this change since it is undoing someone's work: The tape height - on the screen was defined purely by css. But the tape height from the theme was - still being used (to some extent) in the sw. In particular, the Theme's tape height - is returned by function _paintEventTape in file original-painter. It doesn't make - sense for the theme's tape height to be returned by the function when the - actual height of the tape was being controlled in the css file. - -- LarryK rev 1623 -* Un-commented-out - div.style.background = color; - from Timeline.OriginalEventPainter.prototype._createHighlightDiv function - to re-enable event highlighting - See http://groups.google.com/group/simile-widgets/browse_thread/thread/acbffeaa662722f8 - -- Hunt Culver and LarryK rev 1628 -* Bullet-proofing: Fix for issue 34. The Monet example had a latestStart date - after the event's earliestEnd. This caused the tape width to be negative. This - caused an exception when setting the width value, but only on IE. Fix: changed - sources.js to sanity check dates and append error messages to event title if - a problem is detected. Updated test example to have events with bad dates. - Thank you to Tim Dimsdale for noting that the example didn't run in Monet. - -- LarryK rev 1629 -* Tape color for overview painter now set. Uses following precedence: event's color attribute, - theme.event.duration.color or css color for class timeline-small-event-tape - See issue 16 -- LarryK rev 1630 -* Update to send css class to computeSize.

Will be - automatically used after it is released. - -- LarryK rev 1638 -* Added and revised autoWidth. AutoWidth automatically calculates and sets the 'width' for - the Timeline's bands and for the overall Timeline. The 'width,' for horizontal - Timelines, is actually the 'height' style of the various divs. - - The event painters do not calculate the tracks of all the events when they are loaded, - the event tracks are only calculated when they are viewed or are about to be viewed. - In the same way, the needed width is re-calculated whenever a new set of events - are viewed or are about to be viewed. If the new needed width is greater than the - current width, the increase is animated. See the example. - - To use autoWidth: - 1) You will be modifying the classic theme's settings in your html file. - 2) Set the theme's autoWidth to true - 3) Optionally update the theme's autoWidthAnimationTime setting. - 4) Optionally update the autoWidthMargin settings in the Theme. The margin, per - band, is used to set how close the bottom of the lowest track is to the - edge of the band's div. The units are total track width. There are two settings, - one for overview bands, the second for others. - 5) After you have loaded your events, call tl.finishedEventLoading() where tl is the - Timeline object returned from Timeline.create. - Demo: examples/test_example2/test_example2.html - -- LarryK rev 1630, 1643 -* Updated License to refer to JQuery -- LarryK rev 1643 -* Added License file to zip files -- LarryK rev 1643 -* Changed example files to refer to Google Simile directory. -- LarryK rev 1643 -* Fixed: autoWidth wasn't working on Safari/Windows. -- LarryK rev 1644 -* Fixed issue 33: added event attribute durationEvent. - Values of isDuration and durationEvent must be true or false for JSON and - "true" or "false" for XML and SPARCL. Otherwise results are indeterminate. - This can be a breaking change for event sources that were using values - other than the above. -- LarryK rev 1654 -* Added event attribute trackNum for developers to specify a track number. - See issue 26. -- LarryK rev 1654 -* Improve autoWidth for overview bands: calculation should include overviewTrack.offset - -- LarryK rev 1655 -* Add English day names to en locale -- LarryK rev 1656 -* Rebuilt bundle files with new ver of Ajax lib. -- LarryK rev 1658 -* Split band.js out of timeline.js. Assign event IDs sequentially rather than using - random number generator. Add formated ids to event tapes, labels, icons to - enable a single listener to retrieve state from the id. Added support functions - event-utils.js. -- LarryK rev 1659 -* Highlighting testing using Religions example. Restored event highlight colors to theme - to fix. -- LarryK rev 1659 -* New feature: When highlighting events on a Timeline, default is to highlight the event's - icon or tape. If theme.event.highlightLabelBackground is true, the label's background - will also be changed to the highlight color. See the Jewish timeline example. - -- LarryK rev 1659 -* Fixed issue 31, added event's classname attribute to div for icons too. - -- LarryK rev 1659 -* event's tape and highlight div's need index num in id since there can be more - than one tape div per event. -- And id must be unique. -- LarryK rev 1661 -* Added EventPaintListener hook to original-painter. Enables clients to hook into - painting life cycle. See original-painter.js. -- LarryK rev 1661 -* Changed calculation of labelTop for paintImpreciseInstantEvent to be same - calculation as in paintPreciseDurationEvent in original-painter. - Problem was that label was too close to tape (and would sometimes overlap) - for Imprecise Instant Events. Test example 2, imprecise instant event at - year 4400 (with thick tape) looks much better with the change. - -- LarryK rev 1661 -* Added track.offset setting to original-painter. Enables specific - control over top margin of band event painting. Very useful when a - Timeline has multiple event bands or a pseudo event band that is just - used for labeling above an event band. -- LarryK rev 1661 -* Added instant.impreciseIconMargin to original-painter. Enables specific - control over top margin of icon (margin between bottom of tape and - top of icon). Only used if the event has a tape and an icon. - -- LarryK rev 1661 -* Added band arg to eventPaintListener listeners -- LarryK rev 1662 -* Reworked autoWidth to stop recursive call to painter -- LarryK rev 1663 -* Further autoWidth work to have Timeline monitor scroll of bands rather - than having bands call up into Timeline. Eliminated sleep for - smoother scrolling with autoWidth -- LarryK rev 1664 -* Use new maxHeight param from SimileAjax for setting maxHeight of - bubbles. Added theme.bubble.maxHeight with default of 0 (no maximum). - Old theme param of bubble.height is not used within source of - Timeline, so removed it. -- LarryK rev 1667 -* Span decorator improvements: now can have null labels. New param of - inFront. If true, then the span is in front of all layers but the events. - Now uses color attribute if present, else css. -- LarryK rev 1677 -* Span point decorator: Now uses color attribute if present, else css. - -- LarryK rev 1677 -* Timeline start and end feature: Optionally add theme.timeline_start, - theme.timeline_stop to disable movement of the Timeline beyond the - start and/or stop. The setting affects the entire Timeline and must - be set in the theme of the first band. Depending on the relative - resolutions of the bands, different amounts of the various bands - will be seen when at a start or stop edge, depending on which band - was being moved and by how much. In addition to setting the timeline_start - and _stop, you may want to add span decorators to cover up the - unused parts of the Timeline. See example2. Note that the Timeline - will not be movable past a start/stop edge but it can be initially - loaded beyond the edges by using the date parameter of the Band Info. - -- LarryK rev 1677 - -* When you run run.bat, we now serve - http://localhost:9999/ajax/api - from src/webapp/ajax/api/ - http://localhost:9999/timeline - from src/webapp/site/ - http://localhost:9999/timeline/api - from src/webapp/timeline/api/ - -- David H rev 1705 - -* PointHighlightDecorator now uses the width parameter, not CSS. - Issue is that the Point Highlight Decorator is centered on the point in time - being decorated. So the JS needs to calculate based on the width--therefore - don't use CSS for width. Thanks to Christian Thiemann. -* Revised all examples to use new directory layout. - -- LarryK rev 1729 -* Added CompactPainter, which allows for large images and can render - image stacks. See the new compact-painter example. - -- David H rev 1759 -* Added Timeline.version string in timeline.js. Issue 60. - Added Timeline.writeVersion -- a helper that writes out the - current version. Updated examples to use it. - Updated build.xml to include Ajax new styles directory. - Fixed overview painter to use event's classname attribute if present. - Add a test for this to test-example. - -- LarryK rev 1813 -* Fixed build.xml to not include .bak files. - Moved contents of /site up one level into /webapp -- per David H. - Fixed library references in all examples to match new dir layout. - -- LarryK rev 1814 -* Added src/misc/fix_svn_props.txt -- used to correctly set props on - example files. Enables them to be run in browser from svn repo. - Changed timeline-api to use MIT Simile Ajax v 2.2.0. - Changed version to 2.3.0 in anticipation of the release. - -- LarryK rev 1821 -* Also need to set mime type to be text/xml for xml src files. - -- LarryK rev 1822 -* Bug fix: misspelled className as classname -- LarryK rev 1823 -* Fixed IE-only bug. Chokes on . Changed to and all is well. - Another IE only bug: double class name selectors don't work on - IE. Eg
should be selected with css selector .foo.bar (or .bar.foo) - Works everywhere but ie. So added label-, icon-, tape- to className plus className by - itself in original_painter. Additional prefixes: highlight- for event-highlight, - small- for overview painter. Problem was caught by test-example. - -- LarryK rev 1824 -* Updated jetty config file to serve - http://localhost:9999/timeline - from src/webapp/ - Revised Release Notes for release. - -- LarryK rev 1825 -* Changed copyright link to be http://code.google.com/p/simile-widgets/ - -- LarryK rev 1826 -* Rev 1826 is release 2.3.0 -* Added local_example and timeline_local_example.zip. -- LarryK rev 1833 -* Revised local_example zip file to be versioned.

Removed install.sh - -- LarryK rev 1579 -* Event attribute classname is added to the classnames for the event's label - and tape divs. Eg classname of 'hot_event' will result in div classes of - 'timeline-event-label hot_event' and 'timeline-event-tape hot_event' for - the event's Timeline label and tape, respectively. Change is that classname - is now added to the tape's div. -- LarryK rev 1576 -* Re-worked function Timeline.DefaultEventSource.Event in sources.js to use - named arguments (via a hash/anon object) rather than positional arguments. - 19 positional arguments are too many! Now much easier and cleaner to add - additional event attributes. - Note: this is a breaking change for anyone who calls Event directly. But since - the wiki page about dynamic events recommends calling loadXML, etc, I - hoping that this won't cause anyone much pain. And the new format is - MUCH easier to use as a developer. -- LarryK rev 1576 -* New event attribute eventID is a 'cookie' attribute that is stored, not used - by the Timeline library. If you write a custom labeller or event bubble - filler, the attribute can be obtained using the getEventID() method on the - event object. -- LarryK rev 1576 -* New event attribute caption superceedes hoverText. hoverText is deprecated. - For now, it will live on for backwards compatibility. -- LarryK rev 1576 -* Event attributes barImage and barRepeat renamed to tapeImage and tapeRepeat. - No backwards compatibility. (Breaking change from previous checkin) - -- LarryK rev 1576 -* Fix: Event color attribute now properly sets the background color of the bar. - Note that events (where isDuration = true) have opacity applied. See - http://code.google.com/p/simile-widgets/wiki/Timeline_EventSources (LarryK) rev 1569 -* New event attribute barImage sets the event's bar div background-image. - New event attribute barRepeat sets the background-repeat. Default is 'repeat' - Cubism example updated to demonstrate color, textColor, barImage, barRepeat and - hoverText attributes. For a handy stripe generator, see - http://www.stripegenerator.com (LarryK) rev 1569 -* Fix: Event attribute hoverText was not properly processed by JSON or SPARCL sources - (LarryK) rev 1569 -* Build process now creates timeline_source.zip which has source, examples and the - jetty web server. Enables easy access with for folks without svn. (LarryK) rev 1569 -* Added copy of JFK timeline in examples with Dutch locale set. - (LarryK) rev 1560 -* Added forceLocale parameter to timeline-api.js to force a locale for testing - (LarryK) rev 1560 -* Added Dutch localization (Marko) rev 1560 -* Added mouse-wheel scroll. Mouse-wheel acts as left and right arrow keys. Theme - controls whether the mouse-wheel scrolls, zooms or moves the page (if the page - has a scroll-bar). Docs: see webapp/docs/create-timelines.html - (LarryK) rev 1553 -* Additional support in timeline-api for using your own server for Timeline - libraries (LarryK) rev 1553 -* Separation of javascript and css (gm.marko) rev 1326 -* Added mouse-wheel zoom functionality. It operates on a per-band basis, keeping - the date under the mouse cursor static while the timeline around it scales. - Zoom is specified as user-defined steps.

Note: Depending on the relative resolutions of the bands, different - amounts of the various bands will be seen when at a start or stop edge, depending - on which band was being moved and by how much. In addition to setting the timeline_start - and _stop, you may want to add span decorators to cover up the - unused parts of the Timeline. See example2. A Timeline will not be movable - past a start/stop edge but it can be initially loaded beyond the edges by using - the date parameter of the Band Info. - - * Added CompactPainter, which allows for large images and can render - image stacks. See the new compact-painter example. - - * Highlighting event labels: When highlighting events on a Timeline, default is to - highlight the event's icon or tape. If theme.event.highlightLabelBackground is true, - the label's background will also be changed to the highlight color. - See the Jewish timeline example: type a highlight match term in a highlight box. - - * Use new maxHeight param from SimileAjax for setting maxHeight of - bubbles. Added theme.bubble.maxHeight with default of 0 (no maximum). - - - Developer features and changes - * Upgraded to jQuery 1.2.6 minimized file - * Changed timeline-api to use MIT Simile Ajax v 2.2.0. by default. - * New feature tests and demonstrations of features added to test_examples. - See the examples directory. - * Per event css classnames. Double class name selectors don't work on - IE so now add context specific prefixes to css classname supplied with an - event's definition. Eg if an event has classname attribute 'hot' then - original-painter label divs will have class="hot label-hot timeline-event-label" - icon element will have icon-hot and hot, tapes will have tape-hot and hot. - Additional prefixes: highlight- for event-highlight, - small- for overview painter. - * Added tags/latest, a copy of the latest tagged release. Will be used for - referring to examples and other source files from the wiki. - * Event tape heights now use theme.event.tape.height. - * Bullet-proofing: Fix for issue 34. If an event's dates don't make sense then - the library will replace the event's label with an error message. Eg - latestStart date after the event's earliestEnd. Or End before Start, etc. - * Issue (RFE) 26: Added event attribute trackNum for developers to specify - a track number instead of using automatic layout. - * Add English day names to en locale - * Add formated ids to event tapes, labels, icons to - enable a single listener to retrieve state from the id. Added support functions - event-utils.js. - * Added EventPaintListener hook to original-painter. Enables clients to hook into - painting life cycle. See original-painter.js. - * Added track.offset setting to original-painter. Enables specific - control over top margin of band event painting. Very useful when a - Timeline has multiple event bands or a pseudo event band that is just - used for labeling above an event band. -- LarryK rev 1661 - * Added instant.impreciseIconMargin to original-painter. Enables specific - control over top margin of icon (margin between bottom of tape and - top of icon). Only used if the event has a tape and an icon. - * Span decorator improvements: now can have null labels. New param of - inFront. If true, then the span is in front of all layers but the events. - Now uses color attribute if present, else css. -- LarryK rev 1677 - * Span point decorator: Now uses color attribute if present, else css. - * When you run run.bat, we now serve - http://localhost:9999/ajax/api - from src/webapp/ajax/api/ - http://localhost:9999/timeline - from src/webapp/ - http://localhost:9999/timeline/api - from src/webapp/timeline/api/ - * PointHighlightDecorator now uses the width parameter, not CSS. - * Issue (RFE) 60: Added Timeline.version string in timeline.js. - Added Timeline.writeVersion -- a helper that writes out the - current version. Updated examples to use it. - * Fixed overview painter to use event's classname attribute if present. - - - Bug fixes - * Issue 13: Event labels wrap on FF 3 on Mac. - * Issue 16: Tape color for overview painter now set correctly. Uses event's color - attribute, theme.event.duration.color or css color for class timeline-small-event-tape. - * Issue 20: Fixed issues caused when events don't have title attribute. - * Issue 30: Event labels wrap when 'classname' attribute is added and text is bold. - * Issue 31: added event's classname attribute to div for icons too. - * Issue 33: added event attribute durationEvent. - * Event highlighting now working again. - - See the CHANGES.txt file for additional details - - -Version 2.2.0 -- September 23, 2008 - - Known Issues - Firefox 3.x on Macintosh -- width of event labels on the Timeline - are not calculated correctly, causes some labels to wrap. - Issue # 13 on the issues tracker - http://code.google.com/p/simile-widgets/issues - - Developer changes - * Re-built to pick up new simile-ajax that includes jquery 1.2.6 - (eob) - - See the CHANGES.txt file for additional details - - -Version 2.1.0 -- September 19, 2008 - - Known Issues - Firefox 3.x on Macintosh -- width of event labels on the Timeline - are not calculated correctly, causes some labels to wrap. - Issue # 13 on the issues tracker - http://code.google.com/p/simile-widgets/issues - - New features - * mouse-wheel scrolling of timelines. (LarryK) This is the default. - * mouse-wheel zooming of timelines, an alternative to hot zones. - (halcyon1981) - Documentation - http://code.google.com/p/simile-widgets/wiki/MouseWheelScrollingAndZooming - * Improved separation of javascript and css (gm.marko) - - New attributes for events - * tapeImage and tapeRepeat Sets the background image and repeat style for - the event's tape. (LarryK) - * caption - additional event information shown when mouse is hovered over - the Timeline tape or label. (LarryK and Vincent.Vazzo) - * classname - added to the HTML classnames for the event's label and tape - divs. - * eventID - a cookie attribute that is later available for developers via - event_object.GetEventID() (LarryK) - - Documentation revised - http://code.google.com/p/simile-widgets/wiki/Timeline_EventSources - - Attributes deprecated - * hoverText - replaced by caption - - Dutch localization added. (Marko) - - New release files - * timeline_source.zip -- complete source including examples and the - Jetty web server - * timeline_libraries.zip -- minimum Javascript, css and image files needed - - Developer changes - * Timeline.DefaultEventSource.Event in sources.js changed to use - named arguments (via a hash/anon object) rather than positional - arguments.

Also known as aliasing, this feature has been deprecated in the Closure Compiler since its + * initial release, where it is unavailable from the CLI. The Closure Compiler allows one to log and + * influence this process. In contrast, this implementation does not introduce + * any variable declarations in global code and derives String values from + * identifier names used as property accessors.

+ *

Consolidating literals may worsen the data compression ratio when an encoding + * transformation is applied. For instance, jQuery 1.7.1 takes 248235 bytes. + * Building it with + * UglifyJS v1.2.5 results in 93647 bytes (37.73% of the original) which are + * then compressed to 33154 bytes (13.36% of the original) using gzip(1). Building it with the same + * version of UglifyJS 1.2.5 patched with the implementation of consolidation + * results in 80784 bytes (a decrease of 12863 bytes, i.e. 13.74%, in comparison + * to the aforementioned 93647 bytes) which are then compressed to 34013 bytes + * (an increase of 859 bytes, i.e. 2.59%, in comparison to the aforementioned + * 33154 bytes).

+ *

Written in the strict variant + * of ECMA-262 5.1 Edition. Encoded in UTF-8. Follows Revision 2.28 of the Google JavaScript Style Guide (except for the + * discouraged use of the {@code function} tag and the {@code namespace} tag). + * 100% typed for the Closure Compiler Version 1741.
