ScrollBar - Documentation | www.HtmlElements.com

Overview

A scroll bar is a numeric control used to select a numeric value from a range of values by moving a thumb along a track or by clicking on the track itself. It is typically used in conjucntion with the listbox and dropdown elements to allow scrolling through the items. The user can change the value by clicking in the tank area if it is set as an input element.

Getting Started with ScrollBar Web Component

Smart UI for Web Components is distributed as smart-webcomponents NPM package. You can also get the full download from our website with all demos from the Download page.

Setup the ScrollBar

Smart UI for Web Components is distributed as smart-webcomponents NPM package

Download and install the package.
```
npm install smart-webcomponents
```

Once installed, import the ScrollBar module in your application.

<script type="module" src="node_modules/smart-webcomponents/source/modules/smart.scrollbar.js"></script>

Adding CSS reference

The smart.default.css CSS file should be referenced using following code.

<link rel="stylesheet" type="text/css" href="node_modules/smart-webcomponents/source/styles/smart.default.css" />

Add the ScrollBar tag to your Web Page

<smart-scroll-bar id="scrollbar"></smart-scroll-bar>

Create the ScrollBar Component

	<script type="module">
		Smart('#scrollbar', class {
			get properties() {
				return {value: 50}
			}
		});
	</script>

Another option is to create the ScrollBar is by using the traditional Javascript way:

	const scrollbar = document.createElement('smart-scroll-bar');

	scrollbar.disabled = true;
	document.body.appendChild(scrollbar);

Smart framework provides a way to dynamically create a web component on demand from a DIV tag which is used as a host. The following imports the web component's module and creates it on demand, when the document is ready. The #scrollbar is the ID of a DIV tag.

	import "../../source/modules/smart.scrollbar.js";

	document.readyState === 'complete' ? init() : window.onload = init;

	function init() { 
		const scrollbar = new Smart.ScrollBar('#scrollbar', {value: 50});
	}

Open the page in your web server.

Appearance

The scroll bar can be horizontal or vertical. This could be set via orientation property.

 <smart-scroll-bar orientation="vertical"></smart-scroll-bar>

Demo

Behavior

Scrollbar's range is defined by min and max properties.

When scrollbar's button is pressed, the value is increased/decreased by value, defined in step property.

If the user press the left mouse button in the area between a scrollbar button and thumb the value is increased/decreased by the value of largeStep property.

 <smart-scroll-bar min="0" max="100" step="10" large-step="20"></smart-scroll-bar>

Demo

Styling

Smart.ScrollBar uses the following CSS variables for styling:

--smart-scroll-button-size: used to set the size of the scroll buttons. Default value is 16px.

Create, Append, Remove, Get/Set Property, Invoke Method, Bind to Event

Create a new element:

	const scrollbar = document.createElement('smart-scroll-bar');

Append it to the DOM:

	document.body.appendChild(scrollbar);

Remove it from the DOM:

	scrollbar.parentNode.removeChild(scrollbar);

Set a property:

	scrollbar.propertyName = propertyValue;

Get a property value:

	const propertyValue = scrollbar.propertyName;

Invoke a method:

	scrollbar.methodName(argument1, argument2);

Add Event Listener:

	const eventHandler = (event) => {
	   // your code here.
	};

	scrollbar.addEventListener(eventName, eventHandler);

Remove Event Listener:

	scrollbar.removeEventListener(eventName, eventHandler, true);

Using with Typescript

Smart Web Components package includes TypeScript definitions which enables strongly-typed access to the Smart UI Components and their configuration.

Inside the download package, the typescript directory contains .d.ts file for each web component and a smart.elements.d.ts typescript definitions file for all web components. Copy the typescript definitions file to your project and in your TypeScript file add a reference to smart.elements.d.ts

Getting Started with Angular ScrollBar Component

Setup Angular Environment

Angular provides the easiest way to set angular CLI projects using Angular CLI tool.

Install the CLI application globally to your machine.

npm install -g @angular/cli

Create a new Application

ng new smart-angular-scrollbar

Navigate to the created project folder

cd smart-angular-scrollbar

Setup the ScrollBar

Smart UI for Angular is distributed as smart-webcomponents-angular NPM package

Download and install the package.
```
npm install smart-webcomponents-angular
```
Adding CSS reference

The following CSS file is available in ../node_modules/smart-webcomponents-angular/ package folder. This can be referenced in [src/styles.css] using following code.
```
@import 'smart-webcomponents-angular/source/styles/smart.default.css';
```
Another way to achieve the same is to edit the angular.json file and in the styles add the style.
```
"styles": [
		"node_modules/smart-webcomponents-angular/source/styles/smart.default.css"
	]
```
If you want to use Bootstrap, Fluent or other themes available in the package, you need to add them after 'smart.default.css'.

Getting Started with React ScrollBar Component

Setup React Environment

The easiest way to start with React is to use NextJS Next.js is a full-stack React framework. It’s versatile and lets you create React apps of any size—from a mostly static blog to a complex dynamic application.

npx create-next-app my-app
cd my-app
npm run dev

yarn create next-app my-app
cd my-app
yarn run dev

Preparation

Setup the ScrollBar

Smart UI for React is distributed as smart-webcomponents-react package

Download and install the package.

In your React Next.js project, run one of the following commands to install Smart UI ScrollBar for React
With NPM:
```
npm install smart-webcomponents-react
```
With Yarn:
```
yarn add smart-webcomponents-react
```

Once installed, import the React ScrollBar Component and CSS files in your application and render it. app.js

import 'smart-webcomponents-react/source/styles/smart.default.css';
import React from "react";
import ReactDOM from 'react-dom/client';
import { ScrollBar } from 'smart-webcomponents-react/scrollbar';

		this.scrollbar5 = React.createRef();
		this.lowbatteryalert = React.createRef();
		this.powersaver = React.createRef();
	}

	setIcon(sliderName, event) {
		const that = this;

Getting Started with Vue ScrollBar Component

Setup Vue with Vite

In this section we will introduce how to scaffold a Vue Single Page Application on your local machine. The created project will be using a build setup based on Vite and allow us to use Vue Single-File Components (SFCs). Run the following command in your command line

npm create vue@latest

This command will install and execute create-vue, the official Vue project scaffolding tool. You will be presented with prompts for several optional features such as TypeScript and testing support:

✔ Project name: … 
✔ Add TypeScript? … No / Yes
✔ Add JSX Support? … No / Yes
✔ Add Vue Router for Single Page Application development? … No / Yes
✔ Add Pinia for state management? … No / Yes
✔ Add Vitest for Unit testing? … No / Yes
✔ Add an End-to-End Testing Solution? … No / Cypress / Playwright
✔ Add ESLint for code quality? … No / Yes
✔ Add Prettier for code formatting? … No / Yes

Scaffolding project in ./...
Done.

If you are unsure about an option, simply choose No by hitting enter for now. Once the project is created, follow the instructions to install dependencies and start the dev server:

cd 
npm install
npm install smart-webcomponents
npm run dev

Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.

Open vite.config.js in your favorite text editor and change its contents to the following:

vite.config.js

import { fileURLToPath, URL } from 'node:url'

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue({
      template: {
        compilerOptions: {
          isCustomElement: tag => tag.startsWith('smart-')
        }
      }
    })
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  }
})

Open src/App.vue in your favorite text editor and change its contents to the following:

App.vue

We can now use the smart-scroll-bar with Vue 3. Data binding and event handlers will just work right out of the box.

Running the Vue application
