# Custom Title Bar
|
||
|
||
## Basic tutorial
|
||
|
||
Application windows have a default [chrome][] applied by the OS. Not to be confused
|
||
with the Google Chrome browser, window _chrome_ refers to the parts of the window (e.g.
|
||
title bar, toolbars, controls) that are not a part of the main web content. While the
|
||
default title bar provided by the OS chrome is sufficent for simple use cases, many
|
||
applications opt to remove it. Implementing a custom title bar can help your application
|
||
feel more modern and consistent across platforms.
|
||
|
||
You can follow along with this tutorial by opening Fiddle with the following starter code.
|
||
|
||
```fiddle docs/fiddles/features/window-customization/custom-title-bar/starter-code
|
||
|
||
```
|
||
|
||
### Remove the default title bar
|
||
|
||
Let’s start by configuring a window with native window controls and a hidden title bar.
|
||
To remove the default title bar, set the [`BaseWindowContructorOptions`][] `titleBarStyle`
|
||
param in the `BrowserWindow` constructor to `'hidden'`.
|
||
|
||
```fiddle docs/fiddles/features/window-customization/custom-title-bar/remove-title-bar
|
||
|
||
```
|
||
|
||
### Add native window controls _Windows_ _Linux_
|
||
|
||
On macOS, setting `titleBarStyle: 'hidden'` removes the title bar while keeping the window’s
|
||
traffic light controls available in the upper left hand corner. However on Windows and Linux,
|
||
you’ll need to add window controls back into your `BrowserWindow` by setting the
|
||
[`BaseWindowContructorOptions`][] `titleBarOverlay` param in the `BrowserWindow` constructor.
|
||
|
||
```fiddle docs/fiddles/features/window-customization/custom-title-bar/native-window-controls
|
||
|
||
```
|
||
|
||
Setting `titleBarOverlay: true` is the simplest way to expose window controls back into
|
||
your `BrowserWindow`. If you’re interested in customizing the window controls further,
|
||
check out the sections [Custom traffic lights][] and [Custom window controls][] that cover
|
||
this in more detail.
|
||
|
||
### Create a custom title bar
|
||
|
||
Now, let’s implement a simple custom title bar in the `webContents` of our `BrowserWindow`.
|
||
There’s nothing fancy here, just HTML and CSS!
|
||
|
||
```fiddle docs/fiddles/features/window-customization/custom-title-bar/custom-title-bar
|
||
|
||
```
|
||
|
||
Currently our application window can’t be moved. Since we’ve removed the default title bar,
|
||
the application needs to tell Electron which regions are draggable. We’ll do this by adding
|
||
the CSS style `app-region: drag` to the custom title bar. Now we can drag the custom title
|
||
bar to reposition our app window!
|
||
|
||
```fiddle docs/fiddles/features/window-customization/custom-title-bar/custom-drag-region
|
||
|
||
```
|
||
|
||
For more information around how to manage drag regions defined by your electron application,
|
||
see the [Custom draggable regions][] section below.
|
||
|
||
Congratulations, you've just implemented a basic custom title bar!
|
||
|
||
## Advanced window customization
|
||
|
||
### Custom traffic lights _macOS_
|
||
|
||
#### Customize the look of your traffic lights _macOS_
|
||
|
||
The `customButtonsOnHover` title bar style will hide the traffic lights until you hover
|
||
over them. This is useful if you want to create custom traffic lights in your HTML but still
|
||
use the native UI to control the window.
|
||
|
||
```js
|
||
const { BrowserWindow } = require('electron')
|
||
const win = new BrowserWindow({ titleBarStyle: 'customButtonsOnHover' })
|
||
```
|
||
|
||
#### Customize the traffic light position _macOS_
|
||
|
||
To modify the position of the traffic light window controls, there are two configuration
|
||
options available.
|
||
|
||
Applying `hiddenInset` title bar style will shift the vertical inset of the traffic lights
|
||
by a fixed amount.
|
||
|
||
```js title='main.js'
|
||
const { BrowserWindow } = require('electron')
|
||
const win = new BrowserWindow({ titleBarStyle: 'hiddenInset' })
|
||
```
|
||
|
||
If you need more granular control over the positioning of the traffic lights, you can pass
|
||
a set of coordinates to the `trafficLightPosition` option in the `BrowserWindow`
|
||
constructor.
|
||
|
||
```js title='main.js'
|
||
const { BrowserWindow } = require('electron')
|
||
const win = new BrowserWindow({
|
||
titleBarStyle: 'hidden',
|
||
trafficLightPosition: { x: 10, y: 10 }
|
||
})
|
||
```
|
||
|
||
#### Show and hide the traffic lights programmatically _macOS_
|
||
|
||
You can also show and hide the traffic lights programmatically from the main process.
|
||
The `win.setWindowButtonVisibility` forces traffic lights to be show or hidden depending
|
||
on the value of its boolean parameter.
|
||
|
||
```js title='main.js'
|
||
const { BrowserWindow } = require('electron')
|
||
const win = new BrowserWindow()
|
||
// hides the traffic lights
|
||
win.setWindowButtonVisibility(false)
|
||
```
|
||
|
||
:::note
|
||
Given the number of APIs available, there are many ways of achieving this. For instance,
|
||
combining `frame: false` with `win.setWindowButtonVisibility(true)` will yield the same
|
||
layout outcome as setting `titleBarStyle: 'hidden'`.
|
||
:::
|
||
|
||
#### Custom window controls
|
||
|
||
The [Window Controls Overlay API][] is a web standard that gives web apps the ability to
|
||
customize their title bar region when installed on desktop. Electron exposes this API
|
||
through the `titleBarOverlay` option in the `BrowserWindow` constructor. When `titleBarOverlay`
|
||
is enabled, the window controls become exposed in their default position, and DOM elements
|
||
cannot use the area underneath this region.
|
||
|
||
:::note
|
||
`titleBarOverlay` requires the `titleBarStyle` param in the `BrowserWindow` constructor
|
||
to have a value other than `default`.
|
||
:::
|
||
|
||
The custom title bar tutorial covers a [basic example][Add native window controls] of exposing
|
||
window controls by setting `titleBarOverlay: true`. The height, color (_Windows_ _Linux_), and
|
||
symbol colors (_Windows_) of the window controls can be customized further by setting
|
||
`titleBarOverlay` to an object.
|
||
|
||
The value passed to the `height` property must be an integer. The `color` and `symbolColor`
|
||
properties accept `rgba()`, `hsla()`, and `#RRGGBBAA` color formats and support transparency.
|
||
If a color option is not specified, the color will default to its system color for the window
|
||
control buttons. Similarly, if the height option is not specified, the window controls will
|
||
default to the standard system height:
|
||
|
||
```js title='main.js'
|
||
const { BrowserWindow } = require('electron')
|
||
const win = new BrowserWindow({
|
||
titleBarStyle: 'hidden',
|
||
titleBarOverlay: {
|
||
color: '#2f3241',
|
||
symbolColor: '#74b1be',
|
||
height: 60
|
||
}
|
||
})
|
||
```
|
||
|
||
:::note
|
||
Once your title bar overlay is enabled from the main process, you can access the overlay's
|
||
color and dimension values from a renderer using a set of readonly
|
||
[JavaScript APIs][overlay-javascript-apis] and [CSS Environment Variables][overlay-css-env-vars].
