Default is to center the window.
*`y` Integer (optional) - (**required** if x is used) Window's top offset from screen.
Default is to center the window.
*`useContentSize` boolean (optional) - The `width` and `height` would be used as web
page's size, which means the actual window's size will include window
frame's size and be slightly larger. Default is `false`.
*`center` boolean (optional) - Show window in the center of the screen. Default is `false`.
*`minWidth` Integer (optional) - Window's minimum width. Default is `0`.
*`minHeight` Integer (optional) - Window's minimum height. Default is `0`.
*`maxWidth` Integer (optional) - Window's maximum width. Default is no limit.
*`maxHeight` Integer (optional) - Window's maximum height. Default is no limit.
*`resizable` boolean (optional) - Whether window is resizable. Default is `true`.
*`movable` boolean (optional) _macOS__Windows_ - Whether window is
movable. This is not implemented on Linux. Default is `true`.
*`minimizable` boolean (optional) _macOS__Windows_ - Whether window is
minimizable. This is not implemented on Linux. Default is `true`.

closable. This is not implemented on Linux. Default is `true`.
*`focusable` boolean (optional) - Whether the window can be focused. Default is
`true`. On Windows setting `focusable: false` also implies setting
`skipTaskbar: true`. On Linux setting `focusable: false` makes the window
stop interacting with wm, so the window will always stay on top in all
workspaces.
*`alwaysOnTop` boolean (optional) - Whether the window should always stay on top of
other windows. Default is `false`.

*`icon` ([NativeImage](../native-image.md) | string) (optional) - The window icon. On Windows it is
recommended to use `ICO` icons to get best visual effects, you can also
leave it undefined so the executable's icon will be used.
*`show` boolean (optional) - Whether window should be shown when created. Default is
`true`.
*`frame` boolean (optional) - Specify `false` to create a
[frameless window](../../tutorial/window-customization.md#create-frameless-windows). Default is `true`.

*`modal` boolean (optional) - Whether this is a modal window. This only works when the
window is a child window. Default is `false`.
*`acceptFirstMouse` boolean (optional) _macOS_ - Whether clicking an
inactive window will also click through to the web contents. Default is
`false` on macOS. This option is not configurable on other platforms.
*`disableAutoHideCursor` boolean (optional) - Whether to hide cursor when typing.
Default is `false`.
*`autoHideMenuBar` boolean (optional) - Auto hide the menu bar unless the `Alt`
key is pressed. Default is `false`.
*`enableLargerThanScreen` boolean (optional) _macOS_ - Enable the window to

allow larger-than-screen windows by default. Default is `false`.
*`backgroundColor` string (optional) - The window's background color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. Alpha in #AARRGGBB format is supported if `transparent` is set to `true`. Default is `#FFF` (white). See [win.setBackgroundColor](../browser-window.md#winsetbackgroundcolorbackgroundcolor) for more information.
*`hasShadow` boolean (optional) - Whether window should have a shadow. Default is `true`.
*`opacity` number (optional) _macOS__Windows_ - Set the initial opacity of
the window, between 0.0 (fully transparent) and 1.0 (fully opaque). This
is only implemented on Windows and macOS.
*`darkTheme` boolean (optional) - Forces using dark theme for the window, only works on
some GTK+3 desktop environments. Default is `false`.
*`transparent` boolean (optional) - Makes the window [transparent](../../tutorial/window-customization.md#create-transparent-windows).
Default is `false`. On Windows, does not work unless the window is frameless.
*`type` string (optional) - The type of window, default is normal window. See more about
this below.
*`visualEffectState` string (optional) _macOS_ - Specify how the material
appearance should reflect window activity state on macOS. Must be used
with the `vibrancy` property. Possible values are:
*`followWindow` - The backdrop should automatically appear active when the window is active, and inactive when it is not. This is the default.
*`active` - The backdrop should always appear active.
*`inactive` - The backdrop should always appear inactive.
*`hidden` - Results in a hidden title bar and a full size content window. On macOS, the window still has the standard window controls (“traffic lights”) in the top left. On Windows and Linux, when combined with `titleBarOverlay: true` it will activate the Window Controls Overlay (see `titleBarOverlay` for more information), otherwise no window controls will be shown.
*`hiddenInset`_macOS_ - Results in a hidden title bar
`tooltip`, `content`, `under-window`, or `under-page`.
*`backgroundMaterial` string (optional) _Windows_ - Set the window's
system-drawn background material, including behind the non-client area.
Can be `auto`, `none`, `mica`, `acrylic` or `tabbed`. See [win.setBackgroundMaterial](../browser-window.md#winsetbackgroundmaterialmaterial-windows) for more information.
*`zoomToPageWidth` boolean (optional) _macOS_ - Controls the behavior on
macOS when option-clicking the green stoplight button on the toolbar or by
clicking the Window > Zoom menu item. If `true`, the window will grow to
the preferred width of the web page when zoomed, `false` will cause it to
zoom to the width of the screen. This will also affect the behavior when
calling `maximize()` directly. Default is `false`.
*`tabbingIdentifier` string (optional) _macOS_ - Tab group name, allows
opening the window as a native tab. Windows with the same
tabbing identifier will be grouped together. This also adds a native new
tab button to your window's tab bar and allows your `app` and window to
receive the `new-window-for-tab` event.
When setting minimum or maximum window size with `minWidth`/`maxWidth`/
`minHeight`/`maxHeight`, it only constrains the users. It won't prevent you from
passing a size that does not follow size constraints to `setBounds`/`setSize` or
to the constructor of `BrowserWindow`.
The possible values and behaviors of the `type` option are platform dependent.
Possible values are:
* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
`notification`.
* The `desktop` type places the window at the desktop background window level
(kCGDesktopWindowLevel - 1). However, note that a desktop window will not
receive focus, keyboard, or mouse events. You can still use globalShortcut to
receive input sparingly.
* The `dock` type creates a dock-like window behavior.
* The `toolbar` type creates a window with a toolbar appearance.
* The `splash` type behaves in a specific way. It is not
draggable, even if the CSS styling of the window's body contains
-webkit-app-region: drag. This type is commonly used for splash screens.
* The `notification` type creates a window that behaves like a system notification.
* On macOS, possible types are `desktop`, `textured`, `panel`.
* The `textured` type adds metal gradient appearance
(`NSWindowStyleMaskTexturedBackground`).
* The `desktop` type places the window at the desktop background window level
(`kCGDesktopWindowLevel - 1`). Note that desktop window will not receive
focus, keyboard or mouse events, but you can use `globalShortcut` to receive
input sparingly.
* The `panel` type enables the window to float on top of full-screened apps
by adding the `NSWindowStyleMaskNonactivatingPanel` style mask,normally
reserved for NSPanel, at runtime. Also, the window will appear on all
