The close()
method provides a way to close a browser tab group along with all browser tabs within the associated tab collection.
None
void close ()
The following example creates a button on the browser toolbar. When the button is clicked, the collapsed state of all tab groups is checked and any collapsed groups are closed.
//
// 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() {
try {
// Get all the tab groups
var groups = opera.extension.tabGroups.getAll();
// Loop through the groups
for (var i = 0, len = groups.length; i < len; i++) {
// If a group is collapsed, close it
if (groups[i].collapsed === true) {
groups[i].close();
}
}
} catch(e) {}
}
};
// Create the button and add it to the toolbar.
var button = opera.contexts.toolbar.createItem( UIItemProperties );
opera.contexts.toolbar.addItem(button);
