Introduction of Tabbrowser Extensions (Japanese)

This is an archive of the document introducing this extension, for the XUL contest in the Mozilla.Party.jp 4.0. There are some technical information of the implementation.

Extra Methods and Properties (2004-08-10)

Here is a list of some extra methods and properties provided by Tabbrowser Extensions for tab and tabbrowser widget. You can use these properties by your original XUL applications and they will power your apps. Or, if you use customizable extensions about mouse gesures, buttons, etc., you can call TBE features with following methods.

You can use different implementation for with-tabextensions or without, like following:

// ex. A feature to download set of tabs
//    with tabextensions    : Download current tab-group
//    without tabextensions : Download all tabs

var tabs = ('TabbrowserService' in window) ? gBrowser.selectedTab.ownerGroup : [] ;
if (!tabs.length) tabs = gBrowser.mTabContainer.childNodes;

for (var i = 0; i < tabs.length; i++) {
	saveDocument(gBrowser.getBrowserForTab(tabs[i]).contentDocument);
}
		

And, you can call those methods from mouse gestures provided by other extensions, like:

gBrowser.undoRemoveTab();

Extra Events (2004-08-28)

"tabbrowser" elements dispatch following special events if TBE is installed. You can use them to use your custom features about the tabbed browsing.

You can use those events for your implementation like:

// ex. A feature to close new tabs automatically if I open them for movies.

function onTabLoad(aEvent) {
   if (aEvent.tabURI.match(/\.(rm|ram|avi|mov|wmv|asf)$/i)) {
      var tabbrowser = aEvent.target;
      var tab        = tabbrowser.getTabByTabId(aEvent.tabId);
      tabbrowser.removeTab(tab);
   }
}

window.addEventListener('XULTabbrowserTabLoad', onTabLoad, true);
