自定义窗口样式
无边框窗口
无边框窗口移除了所有操作系统的窗口外框，包括窗口控件。
要创建无边框窗口，设置 BrowserWindow 构造函数里的 BaseWindowContructorOptions frame 参数为 false。
docs/fiddles/features/window-customization/custom-window-styles/frameless-windows (41.0.0)Open in Fiddle
- main.js
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()
})
透明窗口
要创建完全透明的窗口，设置 BrowserWindow 构造函数里的 BaseWindowContructorOptions transparent 参数为 true。
下列 Fiddle 利用了透明窗口和 CSS 样式营造出了圆形窗口的视觉效果。
docs/fiddles/features/window-customization/custom-window-styles/transparent-windows (41.0.0)Open in Fiddle
- main.js
- index.html
- styles.css
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()
})
