Ende.BrowserWindowOptions

title

title?: string

width

width?: number

Default: 800

height

height?: number

Default: 600

x

x?: number

y

y?: number

resizable

resizable?: boolean

Default: true

alwaysOnTop

alwaysOnTop?: boolean

Default: false

opacity

opacity?: number

Overall window opacity as a uniform factor in the range 0–1, where 1 is fully opaque (the default) and 0 is fully transparent. Fades the entire window — web content and native chrome alike — like CSS opacity. This is distinct from transparent, which makes the background transparent while honoring the page's own per-pixel alpha. Out-of-range values are clamped. Can also be changed at runtime with BrowserWindow.setOpacity.

Default: 1

frameless

frameless?: boolean

Remove the title bar and standard window chrome (border, traffic light / caption buttons). Set at creation time only.

Default: false

noActivate

noActivate?: boolean

Create the window as a floating, non-activating utility "panel": it floats above normal windows and does not activate the app or steal key focus from the foreground app when shown. Combined with frameless and Tray.getBounds, this is the configuration used for tray / menu-bar popovers. Set at creation time only.

Default: false

transparentTitlebar

transparentTitlebar?: boolean

transparent

transparent?: boolean

Give the window a transparent background so the web content's own alpha composites against whatever is behind the window. Any region the page leaves transparent (e.g. a transparent root background) shows the desktop through it. Often combined with frameless. Distinct from opacity, which uniformly fades the whole window. Set at creation time only.

Supported on macOS and Linux with the system WebView; ignored on Windows and with the CEF backend, which paint an opaque window background.

Default: false
