windows

Interact with browser windows. You can use this API to get information about open windows, to open modify, and close windows. You can also listen for window open, close, and activate events.

Types

windows.WindowType

The type of browser window this is. Under some circumstances a Window may not be assigned type property, for example when querying closed windows from the sessions API.

windows.WindowState

The state of this browser window. Under some circumstances a Window may not be assigned state property, for example when querying closed windows from the sessions API.

windows.Window

This is an actual browser window.

windows.CreateType

Specifies what type of browser window to create. The 'panel' and 'detached_panel' types create a popup unless the '--enable-panels' flag is set.

Properties

windows.WINDOW_ID_NONE

The windowId value that represents the absence of a browser window.

windows.WINDOW_ID_CURRENT

The windowId value that represents the current window.

Functions

windows.get()

Gets details about a window.

windows.getCurrent()

Gets the current window.

windows.getLastFocused()

Gets the window that was most recently focused — typically the window 'on top'.

windows.getAll()

Gets all windows.

windows.create()

Creates (opens) a new browser with any optional sizing, position or default URL provided.

windows.update()

Updates the properties of a window. Specify only the properties that you want to change; unspecified properties will be left unchanged.

windows.remove()

Removes (closes) a window, and all the tabs inside it.

Events

windows.onCreated

Fired when a window is created.

windows.onRemoved

Fired when a window is removed (closed).

windows.onFocusChanged

Fired when the currently focused window changes. Will be windows.WINDOW_ID_NONE if all browser windows have lost focus. Note: On some Linux window managers, WINDOW_ID_NONE will always be sent immediately preceding a switch from one browser window to another.

Browser compatibility

Chrome incompatibilities
