- * @brief Set a callback function on the given window to allow navigations.
- * Must return false if navigation is not allowed, true, otherwise.
- *
- * A 'NULL' navigation handler will remove the current navigation_handler.
- *
- * NB. This currently works only for GtkWebKit WebView implementations.
- * Because GtkWebKit allways navigates, i.e. doesnt react to
- * webui_bind(_webui_win, "", webui_event_handler) which is supposed to
- * catch navigation requests.
- *
- * Also, although bind(win, "", evt_handler) does not work for GtkWebKit,
- * this implementation will always fire an event on navigation, unless
- * mayNavigate() returns true (which is the default, when the callback is not set).
+ * @brief Set a callback to catch the navigation event of the WebView window.
+ * Must return `false` to prevent the navigation event, `true` otherwise.
  *
  * @example
- * bool mayNavigate(size_t window)
- * {
- *  if (_just_called_show_with_url) { return true; }
- *  else { return false; } // expect a navigation event to be handled
+ * bool myNavigationEvent(size_t window) {
+ *    // Prevent WebView window navigation event
+ *    return false;
  * }
+ * webui_set_navigation_handler_wv(myWindow, myNavigationEvent);
