The JSON loader already gives you access to your original JSON event
object. For example, in
Timeline.DefaultEventSource.prototype.loadJSON, look at:
var evt = new Timeline.DefaultEventSource.Event(
...
);
evt._obj = evnt;
evt.getProperty = function(name) {
return this._obj[name];
}
Now you've got a copy of all your original JSON data tacked onto the
Event object. This is much easier than adding additional arguments to
the Event constructor.
Then in your painter code, you can just access whatever attributes
were on your original JSON object:
{"events" : [
{"start" : "2001", "end" : "2003", "title" : "Blah blah",
"flavor" : "Cherry"},
....
]}
You can access the "flavor" attribute in your painter code:
labelDiv.innerHTML = text;
labelDiv.title = evt.getProperty("flavor");
Or in the fillInfoBubble code:
e.g. var title = this.getProperty("myCustomTitleField");
This makes it possible to (with customizations) do just about
anything, displaying all kinds of custom data, creative new painters,
advanced layouts, etc.
