# global-shortcut
|
||
|
|
|
||
|
|
`global-shortcut` 模块可以便捷的为您设置(注册/注销)各种自定义操作的快捷键.
|
||
|
|
|
||
|
|
**Note**: 使用此模块注册的快捷键是系统全局的(QQ截图那种), 不要在应用模块(app module)响应 `ready`
|
||
|
|
消息前使用此模块(注册快捷键).
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var app = require('app');
|
||
|
|
var globalShortcut = require('global-shortcut');
|
||
|
|
|
||
|
|
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();
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
