Custom Window Styles

Frameless windows​

Frameless Window

A frameless window removes all chrome applied by the OS, including window controls.

To create a frameless window, set the BaseWindowContructorOptions frame param in the BrowserWindow constructor to false.

docs/fiddles/features/window-customization/custom-window-styles/frameless-windows (33.3.1)Open in Fiddle
const { app, BrowserWindow } = require('electron')

function createWindow () {
  const win = new BrowserWindow({
    width: 300,
    height: 200,
    frame: false
  })
  win.loadURL('https://example.com')
}

app.whenReady().then(() => {
  createWindow()
})

Transparent windows​

Transparent Window Transparent Window in macOS Mission Control

To create a fully transparent window, set the BaseWindowContructorOptions transparent param in the BrowserWindow constructor to true.

The following fiddle takes advantage of a tranparent window and CSS styling to create the illusion of a circular window.

docs/fiddles/features/window-customization/custom-window-styles/transparent-windows (33.3.1)Open in Fiddle
const { app, BrowserWindow } = require('electron')

function createWindow () {
  const win = new BrowserWindow({
    width: 100,
    height: 100,
    resizable: false,
    frame: false,
    transparent: true
  })
  win.loadFile('index.html')
}

app.whenReady().then(() => {
  createWindow()
})

局限性​

  • 你不能点击穿透透明区域。 See #1335 for details.
  • 透明窗口不可调整大小。 Setting resizable to true may make a transparent window stop working on some platforms.
  • The CSS blur() filter only applies to the window's web contents, so there is no way to apply blur effect to the content below the window (i.e. other applications open on the user's system).
  • 当打开开发者工具时，窗口将不透明。
  • On Windows:
    • 当DWM禁用时，透明窗口将失效。
    • Transparent windows can not be maximized using the Windows system menu or by double clicking the title bar. The reasoning behind this can be seen on PR #28207.
  • On macOS:
    • 在 Mac 上, 原生窗口阴影不会显示在透明窗口中。
