  window.onkeydown = window.onkeyup = function(e) { if (e.keyCode == 27 /* ESC *\/) { e.preventDefault(); } };

Properties

• alwaysOnTop

  boolean optional

  If true, the window will stay above most other windows. If there are multiple windows of this kind, the currently focused window will be in the foreground. Requires the alwaysOnTopWindows permission. Defaults to false.

  Call setAlwaysOnTop() on the window to change this property after creation.

• bounds

  ContentBounds optional

  Deprecated

  Use innerBounds or outerBounds.

  Size and position of the content in the window (excluding the titlebar). If an id is also specified and a window with a matching id has been shown before, the remembered bounds of the window will be used instead.

• focused

  boolean optional

  If true, the window will be focused when created. Defaults to true.

• frame

  string | FrameOptions optional

  Frame type: none or chrome (defaults to chrome). For none, the -webkit-app-region CSS property can be used to apply draggability to the app's window. -webkit-app-region: drag can be used to mark regions draggable. no-drag can be used to disable this style on nested elements.

  Use of FrameOptions is new in M36.

• hidden

  boolean optional

  If true, the window will be created in a hidden state. Call show() on the window to show it once it has been created. Defaults to false.

  URL of the window icon. A window can have its own icon when showInShelf is set to true. The URL should be a global or an extension local URL.

• id

  string optional

  Id to identify the window. This will be used to remember the size and position of the window and restore that geometry when a window with the same id is later opened. If a window with a given id is created while another window with the same id already exists, the currently opened window will be focused instead of creating a new window.

• innerBounds

  BoundsSpecification optional

  Used to specify the initial position, initial size and constraints of the window's content (excluding window decorations). If an id is also specified and a window with a matching id has been shown before, the remembered bounds will be used instead.

  Note that the padding between the inner and outer bounds is determined by the OS. Therefore setting the same bounds property for both the innerBounds and outerBounds will result in an error.

  This property is new in Chrome 36.

• maxHeight

  Deprecated

  Use innerBounds or outerBounds.

  Maximum height of the window.

• maxWidth

  number optional

  Deprecated

  Note that the padding between the inner and outer bounds is determined by the OS. Therefore setting the same bounds property for both the innerBounds and outerBounds will result in an error.

  This property is new in Chrome 36.

• resizable

  boolean optional

  If true, the window will be resizable by the user. Defaults to true.

• showInShelf

  boolean optional

  Chrome 54+

• singleton

  boolean optional

  Deprecated

  Multiple windows with the same id is no longer supported.

  By default if you specify an id for the window, the window will only be created if another window with the same id doesn't already exist. If a window with the same id already exists that window is activated instead. If you do want to create multiple windows with the same id, you can set this property to false.

• state

  State optional

  The initial state of the window, allowing it to be created already fullscreen, maximized, or minimized. Defaults to 'normal'.
