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

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

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

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

 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
    onMouseDown={handleMouseDown} onMouseUp={handleMouseUp} 
>自定义窗口移动</div>
