This documentation relates to Opera's now deprecated .oex Extension API framework for Opera versions <= 12.15 and also provided by our OEX2NEX shim library.
For the latest Opera Extensions API documentation for Opera versions > 12.15 please consult the latest Opera Extensions API documentation online.
The create()
method provides a way to create a new browser tab group, either globally or within the context window. When the create()
method is invoked, the following happens:
tabs
: The tabs to add to the new tab group.properties
: The properties of the new tab group, such as whether it's collapsed.before
: The tab or tab group that the new tab group should be inserted before, usually to the left.BrowserTabGroup create (Array[] tabs, optional BrowserTabGroupProperties properties, optional BrowserTabGroup before)
BrowserTabGroup create (Array[] tabs, optional BrowserTabGroupProperties properties, optional BrowserTab before)
The following example creates a button on the browser toolbar. When the button is clicked, a tab group is created containing two tabs with the specified URLs.
//
// The background process (e.g. index.html)
//
// Specify the properties of the button before creating it.
var UIItemProperties = {
disabled: false,
title: "Example extension",
icon: "images/icon_18.png",
onclick: function() {
// Create two tabs with specified URLs
var tab1 = opera.extension.tabs.create({url: 'http://www.reddit.com/'});
var tab2 = opera.extension.tabs.create({url: 'http://www.digg.com/'});
// Create a tab group containing the above two tabs
var tabGroup = opera.extension.tabGroups.create([tab1, tab2]);
}
};
// Create the button and add it to the toolbar.
var button = opera.contexts.toolbar.createItem( UIItemProperties );
opera.contexts.toolbar.addItem(button);
