UserContentManager.registerScriptMessageHandlerWithReply

bool registerScriptMessageHandlerWithReply(string name, string worldName = null)

Registers a new user script message handler in script world with name world_name.

Different from [webkit.user_content_manager.UserContentManager.registerScriptMessageHandler], when using this function to register the handler, the connected signal is script-message-with-reply-received, and a reply provided by the user is expected. Otherwise, the user will receive a default undefined value.

If null is passed as the world_name, the default world will be used. See [webkit.user_content_manager.UserContentManager.registerScriptMessageHandler] for full description.

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

The registered handler can be unregistered by using [webkit.user_content_manager.UserContentManager.unregisterScriptMessageHandler].

Parameters

nameName of the script message channel
worldNamethe name of a #WebKitScriptWorld

Returns

true if message handler was registered successfully, or false otherwise.
