 * SECTION: WebKitFormSubmissionRequest
 * @Short_description: Represents a form submission request
 * @Title: WebKitFormSubmissionRequest
 * When a form is about to be submitted in a #WebKitWebView, the
 * #WebKitWebView::submit-form signal is emitted. Its request argument
 * contains information about the text fields of the form, that are
 * typically used to store login information, returned as lists by
 * webkit_form_submission_request_list_text_fields(). You can submit the
 * form with webkit_form_submission_request_submit().

 * Get a #GHashTable with the values of the text fields contained in the form

 * contains multiple text input elements with the same name, so this
 * function does not reliably return all text fields.
 * Returns: (allow-none) (transfer none): a #GHashTable with the form
 *    text fields, or %NULL if the form doesn't contain text fields.
 * Deprecated: 2.20. Use webkit_form_submission_request_list_text_fields() instead.
