CreateView
Creates a new view using the specified view_token. Caller should pass the other end of
the token to [fuchsia.ui.gfx/ViewHolderArgs] to attach the new view to a view tree.
See the description of [CreateContextParams.service_directory] for additional services
that must be present when using this method.
CreateViewWithViewRef
Creates a new view using the specified view_token. Caller should pass the other end of
the token to [fuchsia.ui.gfx/ViewHolderArgs] to attach the new view to a view tree.
view_ref can be cloned before passing it to this method, which will allow clients to
track the view.
view_ref_control must not have the ZX_RIGHT_DUPLICATE set, or view creation will fail
and view_token will be closed.
See the description of [CreateContextParams.service_directory] for additional services
that must be present when using this method.
CreateView2
Creates a new Flatland view using the specified view_creation_token defined under args.
Caller should pass the other end of the token to
[fuchsia.ui.composition/Flatland.CreateViewport] to attach the new Flatland view to its
graph.
EnableHeadlessRendering
Enables headless rendering of the Frame.
This is used when content depends on layout and/or animation events firing normally.
May only be used on a Context created with [ContextFeatureFlags.HEADLESS].
Fields
control_handle: FrameControlHandleDisableHeadlessRendering
Stops headless rendering of the Frame.
May only be used on a Context created with [ContextFeatureFlags.HEADLESS].
Fields
control_handle: FrameControlHandleGetMediaPlayer
Returns a [fuchsia.media.sessions2/Player] interface through which media (i.e.
video/audio) playback in the frame may be observed, and/or controlled. Only one
[fuchsia.media.sessions2/Player] may be active at a time, for each [Frame].
Returns an interface through which the [Frame] may be navigated to a desired URL,
reloaded, etc.
controller: An asynchronous interface request for the [Frame]’s [NavigationController].
ExecuteJavaScript
Executes a UTF-8 encoded script in the [Frame] if the [Frame]’s URL has an origin
which matches entries in origins.
At least one origins entry must be specified. If a wildcard "*" is specified in
origins, then the script will be evaluated unconditionally.
Returns the result of executing script, as a JSON-encoded string.
Note that scripts share the same execution context as the document, meaning that document may modify variables, classes, or objects set by the script in arbitrary or unpredictable ways.
If an error occurred, the FrameError will be set to one of these values:
BUFFER_NOT_UTF8:scriptis not UTF-8 encoded.INVALID_ORIGIN: The [Frame]’s current URL does not match any of the values inoriginsororiginsis an empty vector.
ExecuteJavaScriptNoResult
Variant of [Frame.ExecuteJavaScript] which executes the supplied script without returning
a result.
AddBeforeLoadJavaScript
Executes a UTF-8 encoded script for every subsequent page load where the [Frame]’s URL
has an origin reflected in origins. The script is executed early, prior to the execution
of the document’s scripts.
Scripts are identified by a client-managed identifier id. Any script previously injected
using the same id will be replaced.
The order in which multiple bindings are executed is the same as the order in which the
bindings were added. If a script is added which clobbers an existing script of the same
id, the previous script’s precedence in the injection order will be preserved.
At least one origins entry must be specified. If a wildcard "*" is specified in
origins, then the script will be evaluated unconditionally.
If an error occurred, the FrameError will be set to one of these values:
BUFFER_NOT_UTF8:scriptis not UTF-8 encoded.INVALID_ORIGIN:originsis an empty vector.
RemoveBeforeLoadJavaScript
Removes a previously added JavaScript snippet identified by id. This is a no-op if there
is no JavaScript snippet identified by id.
PostMessage
Posts a message to the frame’s onMessage handler.
target_origin restricts message delivery to the specified origin. If target_origin is
"*", then the message will be sent to the document regardless of its origin.
See the
HTML spec
section 9.4.3 for more details on how the target origin policy is applied.
If an error occurred, the FrameError will be set to one of these values:
INTERNAL_ERROR: The WebEngine failed to create a message pipe.BUFFER_NOT_UTF8: The script inmessage’sdataproperty is not UTF-8 encoded.INVALID_ORIGIN:originsis an empty vector.NO_DATA_IN_MESSAGE: Thedataproperty is missing inmessage.
Sets the listener for handling page navigation events.
listener: The observer to use. Unregisters any existing listener if null.
Sets the listener for handling page navigation events. The listener will receive the current navigation state immediately. After that, it’s notified whenever the state changes.
listener: The observer to use. Unregisters any existing listener if null.flags: Flags for optional features that should be enabled for the listener.
SetJavaScriptLogLevel
If set to a value other than [ConsoleLogLevel.NONE], allows web content to log messages
to the [fuchsia.logger/LogSink] configured for this [Frame], via the
console object (e.g. using debug(), log(), info(), warn() and
error()).
The default value is [ConsoleLogLevel.NONE].
As the system log may be persisted, it is recommended that [ConsoleLogLevel.NONE] be used
in Incognito and other private browsing modes.
Log lines are written to the [fuchsia.logger/LogsSink] configured
for this [fuchsia.web/Frame], with severities mapped as follows:
debug(),log()andinfo()are logged at [fuchsia.logger/LogLevelFilter.INFO] severity.warn()is logged at [fuchsia.logger/LogLevelFilter.WARN] severity.error()is logged at [fuchsia.logger/LogLevelFilter.ERROR] severity.
SetConsoleLogSink
Specifies where to emit console log output to. By default log output will be routed to a
[fuchsia.logger/LogSink] obtained via the [fuchsia.web/Context]’s service directory.
sink: The [fuchsia.logger/LogSink] to use to emit logs. Passing anullhandle resets logging to use the default [fuchsia.logger/LogSink].
ConfigureInputTypes
Enables or disables the processing of the specified types of user inputs.
allow specifies whether to enable or disable the specified types.
All input types are enabled by default.
SetPopupFrameCreationListener
Sets the listener for handling popup frame opened by web content. If no listener is present, then any new popup frame will be blocked.
listener: The listener to use. Unregisters any existing listener if null.
Fields
listener: Option<ClientEnd<PopupFrameCreationListenerMarker>>control_handle: FrameControlHandleSetUrlRequestRewriteRules
Supplies a set of UrlRequestRewriteRule to apply on every subsequent URL request.
rulesare cumulative and applied in order.rulesare only applied on the first URL request in a redirect chain.ruleswill be validated before being applied. Ifrulesare invalid, the [Frame] will be closed withERR_INVALID_ARGS.- [
Frame.SetUrlRequestRewriteRules] must not be called again until its acknowledgement callback has been processed. If this happens, the [Frame] will be closed withERR_BAD_STATE.
SetMediaSettings
Sets [fuchsia.media/FrameMediaSettings] for the frame. The specified parameters are
applied to audio streams that started after this message is processed. Should be called
before the Frame is navigated to content in order to ensure that the settings applied to
all media streams. Due to request pipelining, this means doing so before calling
[Frame.GetNavigationController()] and [NavigationController.LoadUrl()].
ForceContentDimensions
Overrides the dimensions reported to web content. The devicePixelRatio reported to
web content will be adjusted in response to changes in the pixel size of the View,
rather than changing the size reported to the content. Call with null web_dips to
remove any prior forced content dimensions.
SetPermissionState
Sets the permission state for the specified permission and web_origin. By default, all
permissions are denied.
SetBlockMediaLoading
Sets whether to block all HTMLMediaElements in the frame from fetching and loading media resources.
May be used, for example, to prevent loading media in frames that are not visible.
While media loading is blocked, elements with autoplay set to true will not start
playback. The promises returned by calls to play() will remain unresolved until loading is
unblocked by a call to this method.
When media loading is unblocked, elements will begin fetching, resource, loading, and playing as appropriate.
Any elements that have begun fetching or loading media resources for the current source
before media loading was blocked will continue to fetch, load, and start playback as
appropriate. This includes calls to play() even after media loading is blocked.
GetPrivateMemorySize
Returns the amount of private (non-shared) physical memory used by the Frame’s main document. The returned size might not reflect the memory usage of embedded iframes.
Fields
responder: FrameGetPrivateMemorySizeResponderSets the navigation policy provider for the [Frame]. When set, the [Frame] sends
[NavigationPolicyProvider.EvaluateRequestedNavigation] when processing navigation
requests. params defines when the message is sent. After sending the
EvaluateRequestedNavigation message, the [Frame] blocks the corresponding navigation
until it receives a response.
Should be called before GetNavigationController to ensure that it is applied to all
navigations including the first [NavigationController.LoadURL] request.
SetContentAreaSettings
Sets various settings for how web content should be run in the Frame. May be called at any time, including after the URL has loaded. Each call changes only the specified fields, overwriting any prior value.
This method will fail with ZX_ERR_NOT_SUPPORTED if any value in ContentAreaSettings
is not supported by the Frame.
ResetContentAreaSettings
Reset the Frame’s ContentAreaSettings to default values.
Fields
control_handle: FrameControlHandleClose
Request graceful or immediate teardown of the Frame content and notification of completion via Frame epitaph.
Graceful teardown allows unload and cleanup tasks in the implementation and web content
(e.g., unload event handlers) to run for up to the specified period of time. Immediate
teardown only runs the minimum cleanup tasks in the implementation and does not allow web
content to run event handlers.
-
If
timeoutis zero, an immediate teardown is initiated. The channel will close withZX_OK. This is equivalent to the caller closing the Frame channel. -
If
timeoutis non-zero, a graceful teardown is initiated. The channel will close withZX_OKif the Frame closes within the specifiedtimeoutand withZX_ERR_TIMED_OUTotherwise. -
If
timeoutis not specified, a reasonable implementation-specific timeout is applied.
Subsequent calls to Close() will override any previously specified Close() timeout.
