问题描述

我一直在寻找当 应用程序 显示或隐藏时的 Electron app 事件.我在文档中看到有 'browser-window-blur' 和 'browser-window-focus' 但是那些不做我想做的事.

I have been looking for Electron app events for when the application is shown or hidden. I see in the docs that there is 'browser-window-blur' and 'browser-window-focus' but those do not do what I want.

我想知道用户何时切换到另一个应用程序或切换回我的应用程序.如果用户在浏览器窗口(包括开发者工具"窗口)之间切换，则会触发上述事件.

I would like to know when the user has switched to another application or switched back to my app. The above events get triggered if the user switches between browser windows –including the "developer's tools" window.

main.js中的代码

app.on('browser-window-focus', () => {
    if (mainWindow) {
        console.log('browser-window-focus');

        mainWindow.webContents.send('projectMsg', { "event": "focus" });
    }
});

app.on('browser-window-blur', () => {
    console.log('browser-window-blur');
    if (mainWindow) {
        mainWindow.webContents.send('projectMsg', { "event": "blur" });
    }
});

推荐答案

在我看来和你描述的完全一样，所以可能要求不同.

It seems to me that it works exactly as you described, so maybe the requirements are different.

此代码

const {app, BrowserWindow} = require('electron')

app.on('browser-window-focus', (event, win) => {
  console.log('browser-window-focus', win.webContents.id)
})
app.on('browser-window-blur', (event, win) => {
  if (win.webContents.isDevToolsFocused()) {
    console.log('Ignore this case')
  } else {
    console.log('browser-window-blur', win.webContents.id)
  }
})
app.once('ready', () => {
  new BrowserWindow()
  new BrowserWindow().webContents.openDevTools({detach: true})
})

考虑到最初没有重点关注，以下列方式工作(在 3.0.3 中):

works the following way (in 3.0.3) given that nothing is focused initially:

• 点击窗口 1 打印 browser-window-focus 1
• 点击窗口 2 打印 browser-window-blur 1 browser-window-focus 2
• 点击devtools窗口打印browser-window-blur 2 忽略这种情况

• Clicking on window 1 prints browser-window-focus 1
• Clicking on window 2 prints browser-window-blur 1 browser-window-focus 2
• Clicking on devtools window prints browser-window-blur 2 Ignore this case

据我所知，这些事件中不包含 devtool，对于任何其他聚焦的窗口(包括 devtool)，窗口会变得模糊

So as far as I see devtool is not included in these events, windows are getting blurred for any other window focused (including devtool)
