TIMELINE: Ability to remove events from the Timeline

[GoogleCodeExporter]

The Timeline doesn't allow you to remove specific events from the TL, but
rather only filter or remove all (aka clear).  It seems straightforward
enough, so I extended via prototype, but this seems to remove from only the
main band.  The other 2 bands (which are syncing) and include only tick
marks don't seem to repaint themselves.  The doc says that clients should
not explicitly call repaint.

Timeline.DefaultEventSource.prototype.remove = function(id) {
    this._events.remove(id);
};
SimileAjax.EventIndex.prototype.remove = function(id) {
    var evt = this._idToEvent[id];
    this._events.remove(evt);
    delete this._idToEvent[id];
};

Thanks.

this is an enhancement NOT a defect, but there was no option to select that.

Are these things I read about adding and removing events at runtime in the 
version in
the svn ?

I'm using the downloaded zip version, but all these snippets don't seem to work.

@litobyte -- the code snippet in this issue report is a proposal for an 
enhancement
to Timeline. As of v2.3, you can not remove events. But you can filter events 
so that
they will not show on the Timeline. See the filtering function.

Hi All !

I'll vote for this request! I have something about 500-2000 events in memory 
and each
time I recieve a update, I'll remove the oldest [for performance/memory 
reasons].
Together with this enhancement I see the following:
- getNewestEvent, together with delete - or - deleteNewestEvent
- getOldestEvent, together with delete - or - deleteOldestEvent
Even if there would be the possibility to remove an event, you must find it! 
Having a
huge number of events, an enumeration operation would be too timeconsuming. So
deleting the oldest would be the best for me [but other may have other needs!].

Thanks a lot!

You should call tl.layout() after deleting an event and the timeline will be 
updated.
