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 icon
attribute is a relative URL pointing to an internal image, or an absolute URL pointing to an external image. The allowed image formats are bmp, gif (not animated), ico, jpg, png and webp. For best results, the icon should be square and small — 16 pixels x 16 pixels is ideal.
DOMString contexts
The following example creates an item with an icon in the context menu to open links in private tabs. In other words, the item will appear only when a link is right-/Ctrl-clicked.
<!--
The configuration file ('config.xml').

<?xml version='1.0' encoding='utf-8'?>

// The background process (e.g. index.html)
//
if (opera.contexts.menu) {
var menu = opera.contexts.menu;
// Create a menu item properties object
var itemProps = {
title: 'Open link in private tab',
contexts: ['link'],
icon: 'images/private.png',
onclick: function(event) {
// Create a tab properties object
var tabProps = {
url: event.linkURL,
private: true
};
// Create a tab with the specified properties
var tab = opera.extension.tabs.create(tabProps);
}
}
// Create a menu item with the specified properties
var item = menu.createItem(itemProps);
// Add the menu item to the context menu
menu.addItem(item);
}
