Prototype object for all GraphicalWindow objects each ECMAScript object that implements GraphicalWindow will have that prototype object in its prototype chain.Idaho Department of Lands (IDL) is committed to conducting open and transparent government business. Properties and the operations as data properties whose value is a built-in function object on a In ECMAScript, the attributes on the IDL interfaces will be exposed as accessor Will expose these attributes and operations in a manner appropriate to the Objects that implement the GraphicalWindow interface

One writable attribute, and two operations defined on it. The GraphicalWindow interface has two read only attributes, Undefined drawText( double x, double y, DOMString text) Undefined drawRectangle( double x, double y, double width, double height) The following is an example of an IDL fragment. ĮxtendedAttributeList Definition DefinitionsĬallbackOrInterfaceOrMixin Namespace Partial Dictionary Enum Typedef IncludesStatement While those specific to the ECMAScript language binding are discussed The extended attributes defined by this specification that are language bindingĪgnostic are discussed in § 2.14 Extended attributes, Which can control how the definition will be handled in language bindings. These are all defined in the following sections.Ĭan be preceded by a list of extended attributes (matching ExtendedAttributeList),

The different kinds of definitions that can appear in an IDL fragment are: interfaces, partial interface definitions, interface mixins, partial mixin definitions, callback functions, callback interfaces, namespaces, partial namespace definitions, dictionaries, partial dictionary definitions, typedefs and includes statements. See IDL grammar for the complete grammar and an explanation of the notation used. A specification that defines Web APIsĬan include one or more IDL fragments thatĭescribe the interfaces (the state and behavior that objects can exhibit)įor the APIs defined by that specification.Ī sequence of definitions that matches the Definitions grammar symbol.Īn implementation supports is not ordered. This section describes a language, Web IDL, which can be used to define Their interfaces using Web IDL, and then use prose to specify API-specific details. Iteration behavior, remain uniform across web platform specifications: such specifications describe ThisĮnsures common tasks, such as installing global properties, processing numeric inputs, or exposing

Well as ECMAScript bindings that detail how those APIs manifest as ECMAScript constructs. How interfaces described with Web IDL correspond to constructs withinĮCMAScript execution environments is also detailed here.Ĭoncretely, Web IDL provides a syntax for specifying the surface APIs of web platform objects, as Number of features that allow the behavior of common script objects in the web platform to be Interfaces that are intended to be implemented in web browsers.
