javascript - 我无法使用变量设置 Electron 窗口的大小

Question

我正在尝试从config.ini文件中读取高度和宽度数据，以将它们设置为BrowserWindow。但是，即使我检查变量是否正确，我的 Electron 窗口也将其设置为800x600。这是我的代码:

app.on("ready", () => {
    //Reading the config.ini file
    //config.ini file uses in main process, preferences.json uses in renderer process
    function readConfig(callback) {
        fs.readFile('./config.ini', 'utf-8', function(err, data) {
            if (err) data = undefined;
            callback(data);
        });
    }

    //I use callback because I wanted to be sure file be readen before initilazing the window.
    readConfig(function(data) {
        if (data !== undefined && data !== null) {
            let config = ini.parse(data);
            windowH = config.height;
            windowW = config.width;
        }
        startApp(windowW, windowH);
    });
});

startApp()函数:

function startApp(w,h) {
    //Electron Window
    mainWindow = new BrowserWindow({
        frame: false,
        width: w,
        height: h,
        minWidth: 800,
        minHeight: 600,
        backgroundColor: '#1f2646',
        icon: __dirname + '/icon.ico',
        webPreferences: {
            nodeIntegration: true,
            devTools: process.env.NODE_ENV === "development",
            enableRemoteModule: true
        }
    });

    console.log(mainWindow.getSize()); //Prints [800, 600]
    console.log("Width:"+w.toString()); //1800
    console.log("Height:"+h.toString()); //1200
}

我立即想通了，我从config.ini中读取的数据是一个字符串。我不敢相信我如何错过那部分。
