# globalShortcut
|
|
|
|
Detect keyboard events when the application does not have keyboard focus.
|
|
|
|
The `globalShortcut` 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.
|
|
|
|
```javascript
|
|
const electron = require('electron');
|
|
const app = electron.app;
|
|
const globalShortcut = electron.globalShortcut;
|
|
|
|
app.on('ready', function() {
|
|
// Register a 'CommandOrControl+X' shortcut listener.
|
|
var ret = globalShortcut.register('CommandOrControl+X', function() {
|
|
console.log('CommandOrControl+X is pressed');
|
|
});
|
|
|
|
if (!ret) {
|
|
console.log('registration failed');
|
|
}
|
|
|
|
// Check whether a shortcut is registered.
|
|
console.log(globalShortcut.isRegistered('CommandOrControl+X'));
|
|
});
|
|
|
|
app.on('will-quit', function() {
|
|
// Unregister a shortcut.
|
|
globalShortcut.unregister('CommandOrControl+X');
|
|
|
|
// Unregister all shortcuts.
|
|
globalShortcut.unregisterAll();
|
|
});
|
|
```
|
|
|
|
## Methods
|
|
|
|
The `globalShortcut` module has the following methods:
|
|
|
|
### `globalShortcut.register(accelerator, callback)`
|
|
|
|
* `accelerator` [Accelerator](accelerator.md)
|
|
* `callback` Function
|
|
|
|
Registers a global shortcut of `accelerator`. The `callback` is called when
|
|
the registered shortcut is pressed by the user.
|
|
|
|
When the accelerator is already taken by other applications, this call will
|
|
silently fail. This behavior is intended by operating systems, since they don't
|
|
want applications to fight for global shortcuts.
|
|
|
|
### `globalShortcut.isRegistered(accelerator)`
|
|
|
|
* `accelerator` [Accelerator](accelerator.md)
|
|
|
|
Returns whether this application has registered `accelerator`.
|
|
|
|
When the accelerator is already taken by other applications, this call will
|
|
still return `false`. This behavior is intended by operating systems, since they
|
|
don't want applications to fight for global shortcuts.
|
|
|
|
### `globalShortcut.unregister(accelerator)`
|
|
|
|
* `accelerator` [Accelerator](accelerator.md)
|
|
|
|
Unregisters the global shortcut of `accelerator`.
|
|
|
|
### `globalShortcut.unregisterAll()`
|
|
|
|
Unregisters all of the global shortcuts.
