Problem is that, when i open a new window in electron app and close it using menu bar close button and again try to open it, then it throws "Object has been destroyed Exception". How do i retain BrowserWindow object even though close button clicked???

推荐答案

应该关闭BrowserWindow对象.重新打开时，您需要实例化一个新对象，而不是尝试重用该引用.

The BrowserWindow object is supposed to be destroyed when closed. You'll need to instantiate a new one when reopening instead of trying to reuse the reference.

如何实例化它取决于您是在主进程(即"Main.js")还是在渲染器进程中进行操作.

How you instantiate it depends on if you're doing it from the main process (i.e. "Main.js") or the renderer process.

在主过程中，它看起来像:

From the main process, it would look like:

var electron = require("electron");
var url = require("url");
var path = require("path");
var newWindow = new electron.BrowserWindow({
    width: 700,
    height: 500
});

newWindow.loadURL(url.format({
    pathname: path.join(__dirname, '/SomeStuff.html'),
    protocol: 'file:',
    slashes: true
}));

如果从渲染器进程实例化，则需要使用远程"对象来访问主进程.这样就可以了:

If instantiating from the renderer process, you need to use the "remote" object to access the main process. So it'd be like:

var newWindow = new electron.remote.BrowserWindow({
    width: 700,
    height: 500
});
