电子-如何知道渲染器窗口何时准备就绪 [英] Electron - How to know when renderer window is ready

问题描述

在我的主要过程中，我创建了一个渲染器窗口：

In my main process I create a renderer window:

var mainWindow = new BrowserWindow({
    height: 600,
    width: 800,
    x: 0,
    y: 0,
    frame: false,
    resizable: true
});
mainWindow.openDevTools();
mainWindow.loadURL('file://' + __dirname + '/renderer/index.html');

然后我想通过某种方式与之进行交流：

Then I want to communicate with it in some way:

mainWindow.webContents.send('message', 'hello world');

但是，主窗口没有收到此消息，因为在窗口未完全完成创建我试图发送它。

However the main window doesn't receive this message because it isn't fully done being created at the time I attempt to send it.

我已经通过将后面的代码包装在setTimeout（）中暂时解决了这个问题，但这绝对不是解决比赛的正确方法条件。

I have temporarily solved this by wrapping the latter code in a setTimeout() but that is most definitely not the right way to resolve a race condition.

主窗口准备就绪时是否存在回调？我尝试了文档中提到的准备展示事件，但没有成功。

Is there a callback for when the main window is ready? I tried the 'ready-to-show' event mentioned in the docs but it did not work.

推荐答案

mainWindow对我不起作用。我改用了 mainWindow.webContents。

A listener on "mainWindow" doesn't worked for me. I used instead "mainWindow.webContents".

mainWindow.webContents.once('dom-ready', () => {});
