Angular RepeatButton - Setup
Smart UI for Angular supports both standalone components (bootstrapApplication) and NgModule-based apps (bootstrapModule(AppModule)). Steps 1-5 show the standalone path; the section below shows the NgModule path with the same package and styles.
Demo source (Smart UI repo): angular/src/repeatbutton/overview
1 NPM Install
Install the smart-webcomponents-angular package:
npm install smart-webcomponents-angular
2 Register styles
Add the default Smart UI stylesheet to angular.json -> projects -> <your-project> -> architect -> build -> options -> styles (merge with existing entries):
"styles": [ "node_modules/smart-webcomponents-angular/source/styles/smart.default.css" ]
Add optional theme CSS from the same package after smart.default.css if you use Bootstrap, Fluent, or other bundled themes.
3 Import the Angular module
Import RepeatButtonModule from smart-webcomponents-angular/repeatbutton: use @Component.imports for standalone, or add it to your AppModule (or feature module) imports array for NgModule apps.
import { RepeatButtonModule } from 'smart-webcomponents-angular/repeatbutton';
4 Root component (standalone)
Add RepeatButtonModule to your root standalone component (src/app/app.ts). Snippet from Smart UI demos (paths normalized to app.html / App where applicable):
import { Component, ViewChild, OnInit, AfterViewInit } from '@angular/core';
import { ProgressBarComponent, CircularProgressBarComponent } from 'smart-webcomponents-angular/progressbar';
import { ProgressBarModule } from 'smart-webcomponents-angular/progressbar';
import { ButtonModule } from 'smart-webcomponents-angular/button';
@Component({
selector: 'app-root',
standalone: true,
imports: [ ProgressBarModule, ButtonModule ],
templateUrl: './app.html',
styleUrl: './app.css'
})
export class App implements AfterViewInit, OnInit {
@ViewChild('progressbar', { read: ProgressBarComponent, static: false }) progressBar!: ProgressBarComponent;
@ViewChild('progressBarCircularControl', { read: CircularProgressBarComponent, static: false }) progressBarCircularControl!: CircularProgressBarComponent;
@ViewChild('progressBarCircular', { read: CircularProgressBarComponent, static: false }) progressBarCircular!: CircularProgressBarComponent;
ngOnInit(): void {
// onInit code.
}
ngAfterViewInit(): void {
// afterViewInit code.
this.init();
}
init(): void {
// init code.
document.getElementById('progressUp')?.addEventListener('click', () => {
this.progressBar.value = Math.min(this.progressBar.max, this.progressBar.value + 1);
this.progressBarCircular.value = Math.min(this.progressBarCircular.max, this.progressBarCircular.value + 1);
});
document.getElementById('progressDown')?.addEventListener('click', () => {
this.progressBar.value = Math.max(this.progressBar.min, this.progressBar.value - 1);
this.progressBarCircular.value = Math.max(this.progressBarCircular.min, this.progressBarCircular.value - 1);
});
document.getElementById('incrementButton')?.addEventListener('click', () => {
this.progressBarCircularControl.value = Math.min(this.progressBarCircularControl.max, this.progressBarCircularControl.value + 1);
});
document.getElementById('decrementButton')?.addEventListener('click', () => {
this.progressBarCircularControl.value = Math.max(this.progressBarCircularControl.min, this.progressBarCircularControl.value - 1);
});
}
}
Boot the app with bootstrapApplication from src/main.ts and an ApplicationConfig in src/app/app.config.ts as generated by the CLI.
5 Template (standalone)
Use your markup in src/app/app.html (or inline template). Bind properties and events on smart-repeat-button as needed:
<div class="smart-demo-container">
<div class="module">
<p>Repeat buttons are normal buttons that repeat a single action until release.</p>
<p>The repeat button can simply trigger an action multiple times depending
on the time interval applied.</p>
</div>
<div class="module">
<div class="repeat-buttons-container">
<smart-repeat-button><i class="material-icons">keyboard_arrow_left</i>
</smart-repeat-button>
<smart-repeat-button><i class="material-icons">keyboard_arrow_right</i>
</smart-repeat-button>
<smart-repeat-button><i class="material-icons">keyboard_arrow_up</i>
</smart-repeat-button>
<smart-repeat-button><i class="material-icons">keyboard_arrow_down</i>
</smart-repeat-button>
</div>
<p>Repeat buttons can be used for navigation.</p>
</div>
<section>
<div class="module">
<div class="repeat-buttons-container">
<smart-repeat-button><i class="material-icons">replay_10</i>
</smart-repeat-button>
<smart-repeat-button><i class="material-icons">forward_10</i>
</smart-repeat-button>
</div>
<p>A repeat button can also be used to configure a range control.</p>
</div>
</section>
<section id="repeat-button-demo">
<div class="module">
<h2>Demo usage</h2>
<br />
<p>Repeating actions can be performed using Repeat buttons.</p>
</div>
<div class="module">
<div class="repeat-buttons-container">
<smart-repeat-button id="progressUp"><i class="material-icons">arrow_upward</i>
</smart-repeat-button>
<smart-repeat-button id="progressDown"><i class="material-icons">arrow_downward</i>
</smart-repeat-button>
</div>
<p>Repeat buttons that control the fill of the progress bar.</p>
</div>
<div class="module">
<div class="progress-bar-container">
<smart-progress-bar #progressbar id="progressBar" orientation="vertical"
[inverted]="true" show-progress-value [value]="5"></smart-progress-bar>
<smart-circular-progress-bar #progressBarCircular id="progressBarCircular"
show-progress-value [value]="5"></smart-circular-progress-bar>
</div>
<p>Progress bars : vertical and circular.</p>
</div>
<div class="module">
<p>Repeat button nested inside a Circular progress bar.</p>
</div>
<div class="module">
<div class="progress-bar-container">
<smart-circular-progress-bar #progressBarCircularControl id="progressBarCircularControl" [value]="25">
<smart-repeat-button id="incrementButton"><i class="material-icons">arrow_upward</i>
</smart-repeat-button>
<smart-repeat-button id="decrementButton"><i class="material-icons">arrow_downward</i>
</smart-repeat-button>
</smart-circular-progress-bar>
</div>
</div>
</section>
</div>
6 NgModule bootstrap (also supported)
Same npm package and angular.json styles as steps 1-2. Put RepeatButtonModule on your NgModule.imports instead of @Component.imports, and bootstrap with bootstrapModule(AppModule).
The demo sources bundled for this widget use standalone only (there is no app.module.ts in that folder). NgModule is fully supported: put RepeatButtonModule from smart-webcomponents-angular/repeatbutton on NgModule.imports, make your root component non-standalone (remove standalone: true and move widget modules from @Component.imports to the module), and bootstrap with platformBrowserDynamic().bootstrapModule(AppModule).
Minimal main.ts + app.module.ts pairing (adjust paths to match your CLI layout):
src/main.ts
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
platformBrowserDynamic().bootstrapModule(AppModule).catch((err) => console.error(err));
src/app/app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { RepeatButtonModule } from 'smart-webcomponents-angular/repeatbutton';
@NgModule({
declarations: [ AppComponent ],
imports: [ BrowserModule, RepeatButtonModule ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
Reuse the template and class logic from steps 4-5 in AppComponent, configured for declarations + NgModule.imports instead of a standalone @Component.
Run
ng serve or npm start - then open http://localhost:4200/.
Smart UI for Angular - full documentation
Accessibility
The RepeatButton component follows WAI-ARIA best practices:
- Keyboard navigation - Tab, Arrow keys, Enter, and Escape are supported
- ARIA roles - Appropriate roles and labels are applied automatically
- Focus management - Visible focus indicators for keyboard users
- Screen readers - State changes are announced to assistive technology
- High contrast - Supports Windows High Contrast Mode and forced colors
For custom labeling, set aria-label or aria-labelledby attributes on the component.
Supported stacks: Smart UI targets Angular 17+, React 18+, Vue 3+, Node 18 LTS, and evergreen browsers; pin exact package versions to your org policy.
