global-shortcut

The global-shortcut module can register/unregister a global keyboard shortcut with the operating system so that you can customize the operations for various shortcuts.

Note: The shortcut is global; it will work even if the app does not have the keyboard focus. You should not use this module until the ready event of the app module is emitted.

const electron = require('electron');
const app = electron.app;
const globalShortcut = electron.globalShortcut;

app.on('ready', function() {
  // Register a 'ctrl+x' shortcut listener.
  var ret = globalShortcut.register('ctrl+x', function() {
    console.log('ctrl+x is pressed');
  });

  if (!ret) {
    console.log('registration failed');
  }

  // Check whether a shortcut is registered.
  console.log(globalShortcut.isRegistered('ctrl+x'));
});

app.on('will-quit', function() {
  // Unregister a shortcut.
  globalShortcut.unregister('ctrl+x');

  // Unregister all shortcuts.
  globalShortcut.unregisterAll();
});

Methods

The global-shortcut module has the following methods:

globalShortcut.register(accelerator, callback)

• accelerator Accelerator
• callback Function

Registers a global shortcut of accelerator. The callback is called when the registered shortcut is pressed by the user. Returns true if the shortcut accelerator was registered, false otherwise. For example, the specified accelerator has already been registered by another caller or other native applications.

globalShortcut.isRegistered(accelerator)

• accelerator Accelerator

Returns true or false depending on whether the shortcut accelerator is registered.

globalShortcut.unregister(accelerator)

• accelerator Accelerator

Unregisters the global shortcut of accelerator.

globalShortcut.unregisterAll()

Unregisters all of the global shortcuts.
