Visio.ShapeCollection class

Package:

visio

Represents the Shape Collection.

Extends

OfficeExtension.ClientObject

Remarks

[ API set: 1.1 ]

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

getCount()	Gets the number of Shapes in the collection.
getItem(key)	Gets a Shape using its key (name or Index).
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.
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 Visio.ShapeCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Visio.Interfaces.ShapeCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.

    return ctx.sync().then(function () {
        console.log("Shapes Count: " + numShapesActivePage.value);
    });
}).catch(function(error) {
    console.log("Error: " + error);
    if (error instanceof OfficeExtension.Error) {
        console.log("Debug info: " + JSON.stringify(error.debugInfo));
    }

Parameters

propertyNames

string | string[]

A comma-delimited string or an array of strings that specify the properties to load.

Returns

Visio.ShapeCollection

load(propertyNamesAndPaths)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.

load(propertyNamesAndPaths?: OfficeExtension.LoadOption): Visio.ShapeCollection;

propertyNamesAndPaths.select is a comma-delimited string that specifies the properties to load, and propertyNamesAndPaths.expand is a comma-delimited string that specifies the navigation properties to load.

Returns

Visio.ShapeCollection

toJSON()
