BrowserWindow.focus()

By Opera Software

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 window.

Parameters:

None

Syntax:

void focus ()

Example:

The following example creates a button in the browser toolbar. When the button is clicked, a new, empty browser window is created and then given focus.

//
// The background process (e.g. index.html) 
//

// Specify the properties of the button before creating it.
var UIItemProperties = {
  disabled: false,
  title: "Window creation test",
  icon: "images/icon_18.png",
  onclick: function() {
    // Open a new browser window
    var win = opera.extension.windows.create();
    
    // Give the new window focus
    win.focus();
  }
};

// Create the button and add it to the toolbar.
var button = opera.contexts.toolbar.createItem( UIItemProperties );  
opera.contexts.toolbar.addItem(button);
