If a touch contact or pen stylus is lifted beyond the range of the digitizer, then it is no longer considered active. For example, the physical size of the contact cannot be surmised due to varying pixel densities of devices (which are not always reported by the user agent). Some sensing devices can detect the close proximity of the input device, and the state is … panning or zooming) are out of scope for this specification. Fonctionnalité expérimentale. If the pointerId provided as the method's argument does not match any of the active pointers, then the user agent must throw a DOMException with the name InvalidPointerId. L'utilisation de pointer-events peut empêcher que des événements soient directement déclenchés sur l'élément avec les pointeurs. A user agent must also fire a pointerout event after firing the pointercancel event. Une action explicite de l'utilisateur est nécessaire pour activer cette fonctionnalité. moving a mouse cursor without any buttons pressed). In the case of devices with multiple ditigizers (e.g. Most commonly, the sensing device is a touch-enabled screen that can sense input from an input device such as a pen, stylus, or finger. W3C Membership. If you'd like … Implementations that use ECMAScript to expose the APIs defined in this specification must implement them in a manner consistent with This pointer is the one that will produce compatibility mouse events. Device types other than mouse must not have a pointerId of 1. For input devices that do not support hover, a user agent must also fire a pointerover event proceeding the pointerdown event. Instead, chorded button presses can be detected by inspecting changes to the button and buttons properties. This document was published by the Microsoft Corporation as a Member Submission. The pointer represents a primary touch input. Si l'un des éléments descendants possède une valeur explicite de pointer-eventsqui lui permet de recevoir des événements de pointeur, les événements qui parcourent les ancêtres pourront déclencher les gestionnaires d'événements as… The click event is defined in [DOM-LEVEL-3-EVENTS] and is not considered a compatibility mouse event as it is typically tied to user interface activation. Spécifications. This value is typically determined by using the hardware's high-resolution performance counter. Submissions of section 3.3 of the W3C Patent Policy. Recommendation: Version non-stable. The events for handling generic pointer input look a lot like those for mouse: pointerdown, pointermove, pointerup, pointerover, pointerout, etc. the ECMAScript Bindings defined in the Web IDL specification [WEBIDL]. It is also useful when single-pointer interaction is desired by an author. Please consult the requirements associated with Member To better abstract this hardware difference and simplify cross-device input authoring, Pointer Events do not fire overlapping pointerdown and pointerup events for chorded button presses (depressing an additional button while another button on the pointer device is already depressed). The compatibility table on this page is generated from structured data. The user inputs a greater number of simultaneous pointers than is supported by the device. Masquer l’inscription à la lettre d’information, Demander de l'aide pour le développement web, Aidez-nous à traduire cet article depuis l’anglais, https://github.com/mdn/browser-compat-data. The following describes the algorithm for how a user agent must map generic pointer input to mouse events for compatibility with this content. If the device producing the event is a mouse, then the pointerId must be 1. For devices that do not report tilt, the value must be 0. As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, have made a formal Submission request to W3C for discussion. Sets pointer capture for the pointer identified by the argument pointerId to the element on which this method is invoked. in addition to new properties for other forms of input: pressure, contact geometry, tilt, etc. The primary goal is to provide a single set of events and interfaces that allow for easy authoring for cross-device pointer input while still allowing for device-specific handling when necessary.
