Custom Electron Titlebar

This project is a typescript library for electron that allows you to configure a fully customizable title bar.

IMPORTANT

This project has been archived and is now read-only. I thank all the people who supported the project with issues, pull request, ideas, etc.
Because I do not have the time to continue with the development of it I have decided to close this project, but, you can always rely on the code to develop something better 😉

It is a library for electron, it cannot be used on a basic website.

Install

npm i custom-electron-titlebar

or use example folder to init basic electron project with this titlebar.

Usage

Step 1

In your renderer file or in an HTML script tag add:

const customTitlebar = require('custom-electron-titlebar');

new customTitlebar.Titlebar({
	backgroundColor: customTitlebar.Color.fromHex('#444')
});

if you are using typescript

import { Titlebar, Color } from 'custom-electron-titlebar'

new Titlebar({
	backgroundColor: Color.fromHex('#ECECEC')
});

The parameter backgroundColor: Color is required, this should be Color type. (View Update Background for more details).
