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.
- LOAD_FLAGS_IS_LINK => 32
-
* 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();
