最近使用了electron框架，发现如果自定义拖动是比较实用的;特别是定制化比较高的项目，如果单纯的使用-webkit-app-region: drag;会让鼠标事件无法触发;
过程中发现问题：
1.windows缩放不是100%后设置偏移界面会缩放，感觉像吹起的气球;
2.单纯的添加css;-webkit-app-region: drag; 会让鼠标事件无法触发;
封装核心方法
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 | import { screen } from 'electron'/* 自定义窗口移动 */export class AzCustomWindowMove { // 是否开启 isOpen: boolean; // 传入要处理的窗口 win: any; // 窗口偏移 winStartPosition: { x: number, y: number, width: number, height: number, } // 现在鼠标所在位置 startPosition: { x: number, y: number, } constructor() { this.isOpen = false; this.win = null; this.winStartPosition = { x: 0, y: 0, width: 0, height: 0, } this.startPosition = { x: 0, y: 0, } } init(win: any) { this.win = win; } start() { this.isOpen = true; // 获取当前窗口偏移[x, y] const winPosition = this.win.getPosition(); // 获取当前缩放[width, height] const winSize = this.win.getSize(); this.winStartPosition.x = winPosition[0]; this.winStartPosition.y = winPosition[1]; this.winStartPosition.width = winSize[0]; this.winStartPosition.height = winSize[1]; // 获取鼠标绝对位置 const mouseStartPosition = screen.getCursorScreenPoint(); this.startPosition.x = mouseStartPosition.x; this.startPosition.y = mouseStartPosition.y; // 开启刷新 this.move(); } move() { if (!this.isOpen) { return; }; console.log('this.win.isDestroyed()', this.win.isDestroyed(), this.win.isFocused()); // 如果窗口已销毁 if (this.win.isDestroyed()) { this.end(); return; } // 判断窗口是否聚焦 if (!this.win.isFocused()) { this.end(); return; } const cursorPosition = screen.getCursorScreenPoint(); const x = this.winStartPosition.x + cursorPosition.x - this.startPosition.x; const y = this.winStartPosition.y + cursorPosition.y - this.startPosition.y; // this.win.setPosition(120, 120, false); // this.win.setBounds({x: 120, y: 120}) // 更新位置的同时设置窗口原大小， windows上设置=>显示设置=>文本缩放 不是100%时，窗口会拖拽放大 this.win.setBounds({ x: x, y: y, width: this.winStartPosition.width, height: this.winStartPosition.height, }) setTimeout(() => { this.move(); }, 20) } end() { this.isOpen = false; }} |
在main.js中引入
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | import { AzCustomWindowMove } from './util';/* new 自定义窗口移动 */const CustomWindowMove = new AzCustomWindowMove();// 创建一个窗口const mainWindow = new BrowserWindow({ frame: false, webPreferences: { preload: join(__dirname, '../preload/index.js'), sandbox: false }})// 将窗口传进去CustomWindowMove.init(mainWindow)// 通信监听ipcMain.on("Main_Window_Operate", (event, info) => { const operateEvent = info.event || ''; switch(operateEvent) { // 拖拽窗口-开始 case 'homeDragWindowStart': { /* 如果别的窗口也想复用这个自定义拖拽方法可以这么用; const webContents = event.sender; const win = BrowserWindow.fromWebContents(webContents); CustomWindowMove.init(win); CustomWindowMove.start(); */ CustomWindowMove.start(); } break; // 拖拽窗口-结束 case 'homeDragWindowEnd': { CustomWindowMove.end(); } break; default: break; } }) |
preload.ts 预加载脚本
1 2 3 4 5 6 7 8 9 10 11 12 13 | import { contextBridge, ipcRenderer } from 'electron'import { electronAPI } from '@electron-toolkit/preload'... contextBridge.exposeInMainWorld('customAPI', { /** * 发布main窗口操作消息 * @param info {type: 操作类型, data: 参数} */ publishMainWindowOperateMessage: (info: {event: string, data: {}}) => { ipcRenderer.send("Main_Window_Operate", info); } })... |
React绑定事件
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | const handleMouseDown = (e) => { (window as any).customAPI.publishMainWindowOperateMessage({event: 'homeDragWindowStart'});}const handleMouseUp = (e) => { (window as any).customAPI.publishMainWindowOperateMessage({event: 'homeDragWindowEnd'});}/*第二个思路, 当按下后监听document的事件*/const handleMouseDown = (e) => { // 通知开始 (window as any).customAPI.publishMainWindowOperateMessage({event: 'homeDragWindowStart'}); // 鼠标抬起 document.onmouseup = function () { document.onmousemove = null; document.onmouseup = null; document.onselectstart = null; // 通知结束 (window as any).customAPI.publishMainWindowOperateMessage({event: 'homeDragWindowEnd'}); }}<div>自定义窗口移动</div> |
