Touch-Unterstützung

Die Beta-Version 1.6.3 enthält erste Unterstützung für die macOS Touch Bar.

---

The new Touch Bar API allows you to add buttons, labels, popovers, color pickers, sliders, and spacers. These elements can be dynamically updated and also emit events when they are interacted with.

This is the first release of this API so it will be evolving over the next few Electron releases. Please check out the release notes for further updates and open issues for any problems or missing functionality.

You can install this version via npm install electron@beta and learn more about it in the TouchBar and BrowserWindow Electron docs.

Big thanks to @MarshallOfSound for contributing this to Electron. 🎉

Touch Bar Example

Below is an example of creating a simple slot machine game in the touch bar. It demonstrates how to create a touch bar, style the items, associate it with a window, handle button click events, and update the labels dynamically.

const { app, BrowserWindow, TouchBar } = require('electron');

const { TouchBarButton, TouchBarLabel, TouchBarSpacer } = TouchBar;

let spinning = false;

// Reel labels
const reel1 = new TouchBarLabel();
const reel2 = new TouchBarLabel();
const reel3 = new TouchBarLabel();

// Spin result label
const result = new TouchBarLabel();

// Spin button
const spin = new TouchBarButton({
  label: '🎰 Spin',
  backgroundColor: '#7851A9',
  click: () => {
    // Ignore clicks if already spinning
    if (spinning) {
      return;
    }

    spinning = true;
    result.label = '';

    let timeout = 10;
    const spinLength = 4 * 1000; // 4 seconds
    const startTime = Date.now();

    const spinReels = () => {
      updateReels();

      if (Date.now() - startTime >= spinLength) {
        finishSpin();
      } else {
        // Slow down a bit on each spin
        timeout *= 1.1;
        setTimeout(spinReels, timeout);
      }
    };

    spinReels();
  },
});

const getRandomValue = () => {
  const values = ['🍒', '💎', '7️⃣', '🍊', '🔔', '⭐', '🍇', '🍀'];
  return values[Math.floor(Math.random() * values.length)];
};

const updateReels = () => {
  reel1.label = getRandomValue();
  reel2.label = getRandomValue();
  reel3.label = getRandomValue();
};

const finishSpin = () => {
  const uniqueValues = new Set([reel1.label, reel2.label, reel3.label]).size;
  if (uniqueValues === 1) {
    // All 3 values are the same
    result.label = '💰 Jackpot!';
    result.textColor = '#FDFF00';
  } else if (uniqueValues === 2) {
    // 2 values are the same
    result.label = '😍 Winner!';
    result.textColor = '#FDFF00';
  } else {
    // No values are the same
    result.label = '🙁 Spin Again';
    result.textColor = null;
  }
  spinning = false;
};

const touchBar = new TouchBar([
  spin,
  new TouchBarSpacer({ size: 'large' }),
  reel1,
  new TouchBarSpacer({ size: 'small' }),
  reel2,
  new TouchBarSpacer({ size: 'small' }),
  reel3,
  new TouchBarSpacer({ size: 'large' }),
  result,
]);

let window;

app.once('ready', () => {
  window = new BrowserWindow({
    frame: false,
    titleBarStyle: 'hidden-inset',
    width: 200,
    height: 200,
    backgroundColor: '#000',
  });
  window.loadURL('about:blank');
  window.setTouchBar(touchBar);
});
