|
|
* When a dynamic result is shown in the urlbar view, its type's view template
|

* is used to construct the part of the view that represents the result.
|
|
*
|
|
* The specified view template will be available to the urlbars in all current
|
|
* and future browser windows until it is unregistered. A given dynamic
|
|
* result type has at most one view template. If this method is called for a
|
|
* dynamic result type more than once, the view template in the last call
|
|
* overrides those in previous calls.
|
|
*
|
|
* @param {string} name
|
|
* The view template will be registered for the dynamic result type with
|
|
* this name.
|
|
* @param {object} viewTemplate
|
|
* This object describes the DOM subtree for the given dynamic result type.
|
|
* It should be a tree-like nested structure with each object in the nesting
|
|
* representing a DOM element to be created. This tree-like structure is
|
|
* achieved using the `children` property described below. Each object in
|
|
* the structure may include the following properties:
|
|
*
|
|
* {string} name
|
|
* The name of the object. It is required for all objects in the
|
|
* structure except the root object and serves two important functions:
|
|
* (1) The element created for the object will automatically have a class
|
|
* named `urlbarView-dynamic-${dynamicType}-${name}`, where
|
|
* `dynamicType` is the name of the dynamic result type. The element
|
|
* will also automatically have an attribute "name" whose value is
|
|
* this name. The class and attribute allow the element to be styled
|
|
* in CSS.
|
|
* (2) The name is used when updating the view. See
|
|
* UrlbarProvider.getViewUpdate().
|
|
* Names must be unique within a view template, but they don't need to be
|
|
* globally unique. i.e., two different view templates can use the same
|
|
* names, and other DOM elements can use the same names in their IDs and
|
|
* classes. The name also suffixes the dynamic element's ID: an element
|
|
* with name `data` will get the ID `urlbarView-row-{unique number}-data`.
|
|
* If there is no name provided for the root element, the root element
|
|
* will not get an ID.
|
|
* {string} tag
|
|
* The tag name of the object. It is required for all objects in the
|
|
* structure except the root object and declares the kind of element that
|
|
* will be created for the object: span, div, img, etc.
|
|
* {object} [attributes]
|
|
* An optional mapping from attribute names to values. For each
|
|
* name-value pair, an attribute is added to the element created for the
|
|
* object. The `id` attribute is reserved and cannot be set by the
|
|
* provider. Element IDs are passed back to the provider in getViewUpdate
|
|
* if they are needed.
|
|
* {array} [children]
|
|
* An optional list of children. Each item in the array must be an object
|
|
* as described here. For each item, a child element as described by the
|
|
* item is created and added to the element created for the parent object.
|
|
* {array} [classList]
|
|
* An optional list of classes. Each class will be added to the element
|
|
* created for the object by calling element.classList.add().
|
|
* {boolean} [overflowable]
|
|
* If true, the element's overflow status will be tracked in order to
|
|
* fade it out when needed.
|
|
* {string} [stylesheet]
|
|
* An optional stylesheet URL. This property is valid only on the root
|
|
* object in the structure. The stylesheet will be loaded in all browser
|
|
* windows so that the dynamic result type view may be styled.

|
|
// menu buttons. Clicking these buttons should not have any side effects in
|
|
// the view or input beyond their primary purpose. For example, the block
|
|
// button should remove the row but it should not change the input value or
|
|
// page proxy state, and ideally it shouldn't change the input's selection
|
|
// or caret either. It probably also shouldn't change the view's selection
|
|
// (if the removed row isn't selected), but that may be more debatable.
|
|
//
|
|
// It may be possible to select buttons on mousedown and then clear the
|
|
// selection on mouseup as usual while meeting these requirements. However,
|
|
// it's not simple because clearing the selection has surprising side
|
|
// effects in the input like the ones mentioned above.
|
|
//
|
|
// (2) Most buttons don't have URLs, so there's nothing to speculatively
|
|
// connect to. If a button does have a URL, it's typically different from
|
|
// the primary URL of its related result, so it's not critical to open a
