electron 注册系统快捷键

1、引入
    	主线程:const {globalShortcut} = require('electron');
    	渲染进程:const {globalShortcut} = require('electron').remote;
    
    2、注册热键
    	CommandOrControl:Command为linux下的常用,Control为windows下的快捷键常用
    
    	 globalShortcut.register("CommandOrControl+键名+...",()=>{
    	      回调
    	  });
    
    3、监听热键是否注册成功
    	globalShortcut.isRegistered('热键内容');  返回布尔值
    
    4、关闭页面、程序时解除热键,避免性能浪费
    	解除单个:lobalShortcut.unregister("热键内容");
    	解除多个:lobalShortcut.unregisterAll();

代码示例:

// Modules to control application life and create native browser window
    const { app, BrowserWindow,BrowserView,globalShortcut} = require('electron')
    const path = require('path')
    
    function createWindow () { 
      // Create the browser window.
      const mainWindow = new BrowserWindow({ 
        width: 800,
        height: 600,
        //弹出的窗口有无边框,默认为有
        // frame:false,
        show:false,
        backgroundColor:'#586148',
        webPreferences: { 
          preload: path.join(__dirname, 'preload.js'),
          nodeIntegration:true,
          webviewTag:true
        },
      })
    
      // and load the index.html of the app.
      mainWindow.loadFile('index.html')
      mainWindow.webContents.on("did-finish-load",()=>{ 
          
      })
      mainWindow.webContents.on('dom-ready',()=>{ 
       
      })
      mainWindow.once('ready-to-show',function(){ 
        mainWindow.show();
      })
      
    
    
      // Open the DevTools.
      // mainWindow.webContents.openDevTools()
    }
    
    // This method will be called when Electron has finished
    // initialization and is ready to create browser windows.
    // Some APIs can only be used after this event occurs.
    // app.whenReady().then(createWindow)
    app.on('ready',()=>{ 
    
      createWindow();
      globalShortcut.register("CommandOrControl+a+b",()=>{ 
          console.log('wallll');
      });
    
      let bool=globalShortcut.isRegistered("CommandOrControl+a+b");
      console.log(bool);
    
    });
    
    // Quit when all windows are closed.
    //关闭客户端解除事件
    app.on('window-all-closed', function () { 
      // On macOS it is common for applications and their menu bar
      // to stay active until the user quits explicitly with Cmd + Q
    
      globalShortcut.unregisterAll();
      if (process.platform !== 'darwin') app.quit()
    })
    
    app.on('activate', function () { 
      // On macOS it's common to re-create a window in the app when the
      // dock icon is clicked and there are no other windows open.
      if (BrowserWindow.getAllWindows().length === 0) createWindow()
    })
    
    // In this file you can include the rest of your app's specific main process
    // code. You can also put them in separate files and require them here.
