This method returns true
if DWM composition (Aero Glass) is
enabled, and false
otherwise.
An example of using it to determine if you should create a transparent window or not (transparent windows won't work correctly when DWM composition is disabled):
const {BrowserWindow, systemPreferences} = require('electron')
let browserOptions = {width: 1000, height: 800}
// Make the window transparent only if the platform supports it.
if (process.platform !== 'win32' || systemPreferences.isAeroGlassEnabled()) {
browserOptions.transparent = true
browserOptions.frame = false
}
// Create the window.
let win = new BrowserWindow(browserOptions)
// Navigate.
if (browserOptions.transparent) {
win.loadURL(`file://${__dirname}/index.html`)
} else {
// No transparency, so we load a fallback that uses basic styles.
win.loadURL(`file://${__dirname}/fallback.html`)
}
