C++ FrameLoader::frameHasLoaded方法代码示例

/**
 * webkit_web_data_source_get_request:
 * @data_source: a #WebKitWebDataSource
 *
 * Returns a #WebKitNetworkRequest that was used to create this
 * #WebKitWebDataSource. The #WebKitNetworkRequest returned by this method is
 * the request that was "committed", and hence, different from the request you
 * get from the webkit_web_data_source_get_initial_request method.
 *
 * Return value: (transfer none): the #WebKitNetworkRequest that
 * created the @data_source or %NULL if the @data_source is not
 * attached to the frame or the frame hasn't been loaded.
 *
 * Since: 1.1.14
