Excel.TimelineStyleCollection class

Package:

excel

Represents a collection of timeline styles.

Extends

OfficeExtension.ClientObject

Remarks

[ API set: ExcelApi 1.10 ]

Properties

context	The request context associated with the object. This connects the add-in's process to the Office host application's process.
items	Gets the loaded child items in this collection.

Methods

add(name, makeUniqueName)	Creates a blank TimelineStyle with the specified name.
getCount()	Gets the number of timeline styles in the collection.
getDefault()	Gets the default timeline style for the parent object's scope.
getItem(name)	Gets a TimelineStyle by name.
getItemOrNullObject(name)	Gets a TimelineStyle by name. If the timeline style doesn't exist, then this method returns an object with its isNullObject property set to true. For further information, see *OrNullObject methods and properties.
load(options)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
setDefault(newDefaultStyle)	Sets the default timeline style for use in the parent object's scope.
toJSON()	Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that is passed to it.) Whereas the original Excel.TimelineStyleCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.TimelineStyleCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
