Welcome to this comprehensive guide on hiding a frameless Electron window on blur. If you’re reading this, chances are you’re trying to create a sleek and modern desktop application using Electron, but you’re struggling to hide the window when it loses focus. Fear not, dear reader, for we’ve got you covered!
What is a Frameless Electron Window?
A frameless Electron window is a type of window that doesn’t have a title bar or any window decorations. It’s often used to create a more immersive and native-like experience for users. However, this comes with a cost – losing the ability to use the standard window controls, like minimizing or closing the window. But don’t worry, we’ll show you how to work around this limitation.
Why Hide the Window on Blur?
Hiding the window on blur is essential for creating a seamless user experience. Imagine having a floating window that remains visible even when the user interacts with another application. It’s distracting and can be annoying. By hiding the window on blur, you can ensure that your application doesn’t interfere with the user’s workflow.
Prerequisites
Before we dive into the tutorial, make sure you have the following installed:
- Node.js (version 14 or higher)
- Electron (version 13 or higher)
- A code editor or IDE of your choice
The Solution
Now that we’ve covered the basics, let’s get to the good stuff! To hide a frameless Electron window on blur, we’ll use a combination of Electron’s built-in events and some clever code.
Step 1: Create a New Electron Project
Start by creating a new Electron project using the following command:
npx electron-cli init my-electron-appThis will generate a basic Electron project structure.
Step 2: Update the `main.js` File
In the `main.js` file, add the following code:
const { app, BrowserWindow } = require('electron');
let win;
function createWindow() {
win = new BrowserWindow({
width: 800,
height: 600,
frame: false, // Create a frameless window
show: false // Don't show the window immediately
});
win.loadURL(`file://${__dirname}/index.html`);
win.on('ready-to-show', () => {
win.show();
});
win.on('blur', () => {
// Hide the window when it loses focus
win.hide();
});
}
app.on('ready', createWindow);
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
if (win === null) {
createWindow();
}
});In this code, we create a new `BrowserWindow` instance with the `frame` option set to `false`, which creates a frameless window. We also add an event listener for the `blur` event, which hides the window when it loses focus.
Step 3: Update the `index.html` File
In the `index.html` file, add the following code:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>My Electron App</title>
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>This code creates a basic HTML page with a heading that says “Hello, World!”.
How it Works
So, how does this code work? When the `blur` event is triggered, the `win.hide()` method is called, which hides the window. This is possible because we set the `show` option to `false` when creating the `BrowserWindow` instance.
When the window is hidden, the user can interact with other applications without being distracted by your floating window. When the user refocuses on your application, the window will reappear.
Troubleshooting
If you’re experiencing issues with the window not hiding or showing correctly, try the following:
- Check that you’re using the latest version of Electron
- Verify that you’ve set the `frame` option to `false` when creating the `BrowserWindow` instance
- Make sure you’ve added the `win.on(‘blur’, () => { win.hide(); });` code in the `createWindow` function
Conclusion
And that’s it! You’ve successfully learned how to hide a frameless Electron window on blur. With this knowledge, you can create sleek and modern desktop applications that provide a seamless user experience.
Remember to experiment with different Electron APIs and events to create even more complex and interactive applications. Happy coding!

FAQs
Got questions? We’ve got answers!
-
Q: What if I want to show the window again?
A: You can use the `win.show()` method to show the window again. For example, you can add an event listener for the `focus` event and call `win.show()` when the window gains focus.
-
Q: Can I use this technique with other Electron APIs?
A: Yes, you can use this technique with other Electron APIs, such as the `ipcMain` module. Just make sure to adapt the code to your specific use case.
-
Q: What if I’m using a different type of window?
A: This technique should work with other types of windows, such as modal windows or popup windows. Just make sure to adjust the code accordingly.

Frequently Asked Question
Get the answers to your most pressing questions on how to hide a frameless Electron window on blur!
What is a frameless Electron window, and why do I need to hide it on blur?
A frameless Electron window is a window without a title bar, which is often used to create a more seamless user experience. However, when the window loses focus (or blurs), it can be distracting to have it still visible. Hiding the window on blur ensures a more polished and professional-looking application.
How do I detect when my Electron window loses focus?
You can use the `browserWindow.blur` event to detect when your Electron window loses focus. This event is emitted when the window loses focus, and you can use it to trigger the hiding of your window.
What is the best way to hide a frameless Electron window on blur?
One approach is to use the `browserWindow.hide()` method to hide the window when it loses focus. Alternatively, you can use CSS to set the window’s `visibility` property to `hidden` or `opacity` to `0`. Both methods will achieve the desired effect of hiding the window.
How can I ensure that my window is restored to its original state when it regains focus?
To restore your window to its original state, you can use the `browserWindow.show()` method or reset the `visibility` and `opacity` properties when the window regains focus. You can also use the `browserWindow.focus` event to detect when the window regains focus and trigger the restoration of the original state.
Are there any potential issues I should be aware of when hiding a frameless Electron window on blur?
Yes, be mindful of potential issues such as unintended hiding of the window when it’s minimized or closed, or conflicts with other event listeners. Make sure to test your implementation thoroughly to ensure a seamless user experience.
