BrowserTab.focus()
From Opera 15 onward, Opera 11 & 12’s extension format is no longer supported, and instead, we’ve switched to Chromium’s extension model. Check out our new documentation for developing extensions for Opera 15 and higher and start building your own extensions.
Description:
The focus()
method provides a way to focus a browser tab.
Parameters:
None

Example:
The following example creates a button on the browser toolbar. When the button is clicked, a tab is created with the specified URL and is given focus.

var UIItemProperties = {
disabled: false,
title: "Example extension",

onclick: function() {
// Create a tab with the specified URL
var tab = opera.extension.tabs.create({url: 'http://dev.opera.com/'});
// Give focus to the new tab
tab.focus();
}
};
// Create the button and add it to the toolbar.
