NAME

Mozilla::DOM::WebNavigation

Mozilla::DOM::WebNavigation is a wrapper around an instance of Mozilla's nsIWebNavigation interface. This class inherits from Supports.

Note: the nsIWebNavigation interface isn't marked FROZEN in Gecko, so it can change.

You can get this object by QueryInterfacing WebBrowser:

  $iid = Mozilla::DOM::WebNavigation->GetIID;
  $navigation = $browser->QueryInterface($iid);

XXX: The following methods are unfortunately not wrapped yet: LoadURI, GetSessionHistory, SetSessionHistory. I'd especially like to have LoadURI, but I don't know how to do nsIInputStream for its last two arguments.

The following constants are available. You can export them all with use Mozilla::DOM::WebNavigation qw(:flags) or export them individually.

LOAD_FLAGS_MASK => 65535
LOAD_FLAGS_NONE => 0
  * Normal load flag.
LOAD_FLAGS_IS_REFRESH => 16
  * Meta-refresh flag.  The cache is bypassed.  This type of load is
  *                     usually the result of a meta-refresh tag, or a HTTP
  *                     'refresh' header.
  * Link-click flag. 
LOAD_FLAGS_BYPASS_HISTORY => 64
  * Bypass history flag.
LOAD_FLAGS_REPLACE_HISTORY => 128
  * Replace history entry flag.
LOAD_FLAGS_BYPASS_CACHE => 256
LOAD_FLAGS_BYPASS_PROXY => 512
LOAD_FLAGS_CHARSET_CHANGE => 1024
STOP_NETWORK => 1
  * Stop all network activity.  This includes both active network loads and
  * pending meta-refreshes.
STOP_CONTENT => 2
  * Stop all content activity.  This includes animated images, plugins and
  * pending Javascript timeouts.
STOP_ALL => 3
  * Stop all activity.

CLASS METHODS

$iid = Mozilla::DOM::WebNavigation->GetIID()

Pass this to QueryInterface.

METHODS

$bool = $webnavigation->GetCanGoBack()

      * Indicates if the object can go back.  If true this indicates that
      * there is back session history available for navigation.

    Note: this method is available in Gtk2::MozEmbed:

      $embed->can_go_back

$bool = $webnavigation->GetCanGoForward()

      * Indicates if the object can go forward.  If true this indicates that
      * there is forward session history available for navigation

    Note: this method is available in Gtk2::MozEmbed:

      $embed->can_go_forward

$currenturi = $webnavigation->GetCurrentURI()

      * The currently loaded URI or null.

    Note: I think this is the same as

      $embed->get_location

    in Gtk2::MozEmbed.

$document = $webnavigation->GetDocument()

      * Retrieves the current DOM document for the frame, or lazily creates a
      * blank document if there is none. This attribute never returns null except
      * for unexpected error situations.

    Note: this document is also available by doing

        my $browser = $embed->get_nsIWebBrowser;
        my $window = $browser->GetContentDOMWindow;
        my $doc = $window->GetDocument;

$referringuri = $webnavigation->GetReferringURI()

      * The referring URI.

$webnavigation->GoBack()

      * Tells the object to navigate to the previous session history item.  When
      * a page is loaded from session history, all content is loaded from the
      * cache (if available) and page state (such as form values, scroll position)
      * is restored.
      *
      * @return NS_OK               - Backward navigation was successful.
      *         NS_ERROR_UNEXPECTED - This call was unexpected at this time.  Most
      *                               likely you can't go back right now.

    Note: this method is available in Gtk2::MozEmbed:

      $embed->go_back()

$webnavigation->GoForward()

      * Tells the object to navigate to the next Forward session history item.
      * When a page is loaded from session history, all content is loaded from
      * the cache (if available) and page state (such as form values, scroll
      * position) is restored.
      *
      * @return NS_OK               - Forward was successful.
      *         NS_ERROR_UNEXPECTED - This call was unexpected at this time.  Most
      *                               likely you can't go forward right now.

    Note: this method is available in Gtk2::MozEmbed:

      $embed->go_forward()

$webnavigation->GotoIndex($index)

    • $index (integer (long))

      * Tells the object to navigate to the session history item at index.
      *
      * @return NS_OK -               GotoIndex was successful.
      *         NS_ERROR_UNEXPECTED - This call was unexpected at this time.  Most
      *                               likely you can't goto that index

$webnavigation->Reload($reloadflags)

    • $reloadFlags (integer (long))

      * Tells the Object to reload the current page.
      *
      * @param reloadFlags - Flags modifying reload behaviour. Generally you will
      *                      pass LOAD_FLAGS_NONE for this parameter.

    Note: this method is available in Gtk2::MozEmbed:

      $embed->reload($flags)

    (See also the section "flags Gtk2::MozEmbed::Reload" in `perldoc Gtk2::MozEmbed::main`.)

$webnavigation->Stop($stopflags)

    • $stopFlags (integer (long))

      * Stops a load of a URI.
      *
      * @param stopFlags - Flags indicating the stop behavior.

    Note: this method is available in Gtk2::MozEmbed:

      $embed->stop_load();
