    • run

      boolean run(@Nullable PermissionStateQuery query)

      This signal allows the User-Agent to respond to permission requests for powerful features, as specified by the Permissions W3C Specification. You can reply to the query using webkit_permission_state_query_finish().

      You can handle the query asynchronously by calling webkit_permission_state_query_ref() on query and returning true. If the last reference of query is removed and the query has not been handled, the query result will be set to WEBKIT_QUERY_PERMISSION_PROMPT.
