electron笔记无边框窗口、DLL调用、DLL函数返回指针

无边框

const win = new BrowserWindow({width: 1290,height: 736,minHeight: 736,minWidth: 1040,maxHeight: 736,maxWidth: 1290,frame: false, // 无边框webPreferences: {// preload: process.env.WEBPACK_DEV_SERVER_URL ? __dirname + '/preload.js' : 'app://./preload.js',// devTools: true,// Use pluginOptions.nodeIntegration, leave this alone// See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more infonodeIntegration: true,contextIsolation: false}})

窗口鼠标拖拽移动

ipcMain.handle("window-move-open", (event, canMoving) => {let winStartPosition = { x: 0, y: 0 };let mouseStartPosition = { x: 0, y: 0 };const currentWindow = BrowserWindow.getFocusedWindow();const currentWindowSize = currentWindow.getSize();if (currentWindow) {if (canMoving) {const winPosition = currentWindow.getPosition();winStartPosition = { x: winPosition[0], y: winPosition[1] };mouseStartPosition = screen.getCursorScreenPoint();if (movingInterval) {clearInterval(movingInterval);}movingInterval = setInterval(() => {if (!currentWindow.isDestroyed()) {if (!currentWindow.isFocused()) {clearInterval(movingInterval);movingInterval = null;}const cursorPosition = screen.getCursorScreenPoint();const x =winStartPosition.x + cursorPosition.x - mouseStartPosition.x;const y =winStartPosition.y + cursorPosition.y - mouseStartPosition.y;currentWindow.setBounds({x: x,y: y,width: currentWindowSize[0],height: currentWindowSize[1],});}}, 10);} else {clearInterval(movingInterval);movingInterval = null;}}});

调用dll
nodejs调用dll依赖ffi模块，如何安装ffi依赖？

需要注意的问题：
1.首先要判断dll是32位还是64位？

桌面左下角搜索，输入vs，选择vs开发者命令行工具，输入dumpbin /headers XXX.dll，
如果是x86 32 bit，则为32位，反之是64

2.根据dll是32位还是64位，选择对应的nodejs版本以及electron。

3.安装windows-build-tools出现卡住的问题？

如何调用dll

const dllPath = process.cwd()+'\\5.6.0.8_64.dll';
let strPtr = refArray('uchar',16)
const library = ffi.Library(dllPath,{DyInit: ['int',[]],DyGetPushStreamUrl:[ref.refType(strPtr),[]],DyUnInit: ['int',[]],DyGetVersion: [ref.refType(strPtr),[]],
})let res =  library.DyGetVersion()console.log(res.toString())
