opera.extension.tabGroups.create()

By Opera Software

Description:

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:

1. If this is the global tab group manager, a tab group is created using tabs, properties and before as the arguments, if provided.
2. If this is a window tab group manager, a tab group is created within the context window using tabs, properties and before as the arguments, if provided.

Parameters:

• 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.

Syntax:

BrowserTabGroup create (Array[] tabs, optional BrowserTabGroupProperties properties, optional BrowserTabGroup before)

BrowserTabGroup create (Array[] tabs, optional BrowserTabGroupProperties properties, optional BrowserTab before)

Example:

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);
