register_script_message_handler_with_reply

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

Different from register_script_message_handler, 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 register_script_message_handler 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 unregister_script_message_handler.

Parameters:

this	A UserContentManager
name	Name of the script message channel world_name (nullable): the name of a WebKitScriptWorld

Returns:

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