electron-webcontents-shortcut
Overview
This project is inspired by another project, electron-localshortcut, with a similar implementation principle but enhanced functionality. In comparison to electron-localshortcut
, this project offers greater flexibility, allowing users to freely bind shortcuts in the multi-process environment of Electron applications, including BrowserWindow
, BrowserView
, and Webview
.
Background
In electron-localshortcut
, shortcuts can only be bound to a BrowserWindow
, limiting its use in Electron applications with multiple processes that may involve the use of BrowserView
or Webview
. To address this limitation, this project relaxes the constraints imposed by electron-localshortcut
, enabling users to bind shortcuts to any source of WebContents
, thus better accommodating the needs of multi-process applications.
Features
- Flexibility: Shortcuts can be bound to sources from any
WebContents
, includingBrowserWindow
,BrowserView
,Webview
, and more.
Installation
Install via npm:
npm install electron-webcontents-shortcut
Usage
Import this module into your Electron project:
const shortcutManager = require('electron-webcontents-shortcut');
Then, use the following methods to bind shortcuts:
const { register } = shortcutManager;
app.whenReady().then(() => {
const win = new BrowserWindow({
width: 600,
height: 400,
});
win.loadURL('https://www.electronjs.org//');
register(win.webContents, 'Ctrl+Shift+O', () => {
console.log('Ctrl+Shift+O');
win.webContents.openDevTools({ mode: 'detach' });
});
});
API
1. isAccelerator(input: string): boolean
Checks whether a given string is a valid representation of a keyboard accelerator. A valid accelerator should consist of any number of modifier keys followed by a regular key. For example, Shift+Alt+P
.
2. unregisterAll(webContents: WebContents): void
Unregisters all keyboard shortcuts associated with the specified webContents
.
3. register(webContents: WebContents, accelerator: string | string[], callback: () => void): void
Registers a keyboard shortcut on the specified webContents
. The accelerator
parameter can be a string or an array of strings representing the keyboard shortcut(s), and the callback
function will be invoked when the shortcut is triggered.
4. unregister(webContents: WebContents, accelerator: string | string[]): void
Unregisters the specified keyboard shortcut(s) associated with the given webContents
.
5. isRegistered(webContents: WebContents, accelerator: string): boolean
Checks whether a specific keyboard shortcut is registered on the specified webContents
.
Example Usage
const {
isAccelerator,
register,
unregister,
unregisterAll,
isRegistered,
} = require('electron-webcontents-shortcut');
// Check if a string is a valid accelerator
if (isAccelerator('Ctrl+A')) {
const webContents = // ... obtain WebContents instance
// Register a keyboard shortcut
register(webContents, 'Ctrl+A', () => {
// Handle the shortcut
});
// Check if a shortcut is registered
if (isRegistered(webContents, 'Ctrl+A')) {
// Do something
}
// Unregister a shortcut
unregister(webContents, 'Ctrl+A');
// Unregister all shortcuts
unregisterAll(webContents);
}
