Exported types

newtype UserContentManager

Memory-managed wrapper type.

Constructors

UserContentManager (ManagedPtr UserContentManager)

Instances

GObject UserContentManager

Methods

gobjectType :: UserContentManager -> IO GType

IsObject UserContentManager

IsUserContentManager UserContentManager

class GObject o => IsUserContentManager o

Type class for types which can be safely cast to UserContentManager, for instance with toUserContentManager.

Instances

(GObject a, (UnknownAncestorError UserContentManager a :: Constraint)) => IsUserContentManager a

IsUserContentManager UserContentManager

toUserContentManager :: (MonadIO m, IsUserContentManager o) => o -> m UserContentManager

Cast to UserContentManager, for types for which this is known to be safe. For general casts, use castTo.

noUserContentManager :: Maybe UserContentManager

A convenience alias for Nothing :: Maybe UserContentManager.

Methods

addScript

userContentManagerAddScript

Arguments

:: (HasCallStack, MonadIO m, IsUserContentManager a)

=> a

manager: A UserContentManager

-> UserScript

script: A UserScript

-> m ()

Adds a UserScript to the given UserContentManager. The same UserScript can be reused with multiple UserContentManager instances.

Since: 2.6

addStyleSheet

userContentManagerAddStyleSheet

Arguments

:: (HasCallStack, MonadIO m, IsUserContentManager a)

=> a

manager: A UserContentManager

-> UserStyleSheet

stylesheet: A UserStyleSheet

-> m ()

Adds a UserStyleSheet to the given UserContentManager. The same UserStyleSheet can be reused with multiple UserContentManager instances.

Since: 2.6

new

userContentManagerNew

Arguments

:: (HasCallStack, MonadIO m)

=> m UserContentManager

Returns: A UserContentManager

Creates a new user content manager.

Since: 2.6

registerScriptMessageHandler

userContentManagerRegisterScriptMessageHandler

Arguments

:: (HasCallStack, MonadIO m, IsUserContentManager a)

=> a

manager: A UserContentManager

-> Text

name: Name of the script message channel

-> m Bool

Returns: True if message handler was registered successfully, or False otherwise.

Registers a new user script message handler. After it is registered, scripts can use window.webkit.messageHandlers.<name>.postMessage(value) to send messages. Those messages are received by connecting handlers to the UserContentManager::script-message-received signal. The handler name is used as the detail of the signal. To avoid race conditions between registering the handler name, and starting to receive the signals, it is recommended to connect to the signal *before* registering the handler name:

<informalexample><programlisting> WebKitWebView *view = webkit_web_view_new (); WebKitUserContentManager *manager = webkit_web_view_get_user_content_manager (); g_signal_connect (manager, "script-message-received::foobar", G_CALLBACK (handle_script_message), NULL); webkit_user_content_manager_register_script_message_handler (manager, "foobar"); </programlisting></informalexample>

Registering a script message handler will fail if the requested name has been already registered before.

Since: 2.8

removeAllScripts

userContentManagerRemoveAllScripts

Arguments

:: (HasCallStack, MonadIO m, IsUserContentManager a)

=> a

manager: A UserContentManager

-> m ()

Removes all user scripts from the given UserContentManager

Since: 2.6

removeAllStyleSheets

userContentManagerRemoveAllStyleSheets

Arguments

:: (HasCallStack, MonadIO m, IsUserContentManager a)

=> a

manager: A UserContentManager

-> m ()

Removes all user style sheets from the given UserContentManager.

Since: 2.6

unregisterScriptMessageHandler

userContentManagerUnregisterScriptMessageHandler

Arguments

:: (HasCallStack, MonadIO m, IsUserContentManager a)

=> a

manager: A UserContentManager

-> Text

name: Name of the script message channel

-> m ()

Unregisters a previously registered message handler.

Note that this does *not* disconnect handlers for the UserContentManager::script-message-received signal, they will be kept connected, but the signal will not be emitted unless the handler name is registered again.

Signals

scriptMessageReceived

type C_UserContentManagerScriptMessageReceivedCallback = Ptr () -> Ptr JavascriptResult -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type UserContentManagerScriptMessageReceivedCallback

Arguments

 = JavascriptResult

jsResult: the JavascriptResult holding the value received from the JavaScript world.

-> IO ()

This signal is emitted when JavaScript in a web view calls <code>window.webkit.messageHandlers.&lt;name&gt;.postMessage()</code>, after registering <code>&lt;name&gt;</code> using userContentManagerRegisterScriptMessageHandler

Since: 2.8

afterUserContentManagerScriptMessageReceived :: (IsUserContentManager a, MonadIO m) => a -> UserContentManagerScriptMessageReceivedCallback -> m SignalHandlerId

Connect a signal handler for the “script-message-received” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after userContentManager #scriptMessageReceived callback

genClosure_UserContentManagerScriptMessageReceived :: UserContentManagerScriptMessageReceivedCallback -> IO Closure

Wrap the callback into a Closure.

mk_UserContentManagerScriptMessageReceivedCallback :: C_UserContentManagerScriptMessageReceivedCallback -> IO (FunPtr C_UserContentManagerScriptMessageReceivedCallback)

Generate a function pointer callable from C code, from a C_UserContentManagerScriptMessageReceivedCallback.

noUserContentManagerScriptMessageReceivedCallback :: Maybe UserContentManagerScriptMessageReceivedCallback

A convenience synonym for Nothing :: Maybe UserContentManagerScriptMessageReceivedCallback.

onUserContentManagerScriptMessageReceived :: (IsUserContentManager a, MonadIO m) => a -> UserContentManagerScriptMessageReceivedCallback -> m SignalHandlerId

Connect a signal handler for the “script-message-received” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on userContentManager #scriptMessageReceived callback

wrap_UserContentManagerScriptMessageReceivedCallback :: UserContentManagerScriptMessageReceivedCallback -> C_UserContentManagerScriptMessageReceivedCallback

Wrap a UserContentManagerScriptMessageReceivedCallback into a C_UserContentManagerScriptMessageReceivedCallback.
