37 * When a form is about to be submitted in a #WebKitWebView, the

39 * contains information about the text fields of the form, that are
40 * typically used to store login information, returned in a
41 * #GHashTable by the webkit_form_submission_request_get_text_fields()
42 * method, and you can finally submit the form with
43 * webkit_form_submission_request_submit().
