Electron 独自window #Electron

ChromiumのUIを使わず、自分でwindowのUIをつくりたいとき
閉じる、最大化、最小化ボタンくらいはつくる。

main.js

const el = require('electron'), {app} = el;
const Bw = electron.BrowserWindow, ipc = electron.ipcMain;

let win = null;
app.on('window-all-closed', () => {
    if (process.platform !== 'darwin') app.quit();
});
app.on('activate', () => {
    if (win === null) createMainWindow();
});
app.on('ready', createMainWindow);

function createMainWindow(){
    win = new Bw({
        title: '',
        width: 1280,
        height: 720,
        minWidth: 150,
        minHeight: 100,
        frame: false,
        darkTheme: true,
        'standard-window': false,      // これと
        titleBarStyle: 'hidden-inset', // これが
        'overlay-scrollbars': true,
        resizable: true,
        transparent: true,
        webPreferences: {},
        fullscreenable: true,
    }),
    win.loadURL(`file://${__dirname}/index.html`),
    win.on('closed', () => {win = null;});
};

ipc.on('minimize', (e, arg) => {
    win.minimize();
});
ipc.on('maximize', (e, arg) => {
    win.isMaximized() ? win.unmaximize() : win.maximize();
});
