Angular Window - 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/window/basic

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 WindowModule from smart-webcomponents-angular/window: use @Component.imports for standalone, or add it to your AppModule (or feature module) imports array for NgModule apps.

import { WindowModule } from 'smart-webcomponents-angular/window';

4 Root component (standalone)

Add WindowModule 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, ViewEncapsulation } from '@angular/core';
import { ButtonComponent } from 'smart-webcomponents-angular/button';
import { WindowComponent } from 'smart-webcomponents-angular/window';

import { ButtonModule } from 'smart-webcomponents-angular/button';

import { WindowModule } from 'smart-webcomponents-angular/window';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [ ButtonModule, WindowModule ],
  templateUrl: './app.html',
  styleUrl: './app.css'
})

export class App implements AfterViewInit, OnInit {	
	@ViewChild('button', { read: ButtonComponent, static: false }) button!: ButtonComponent;
	@ViewChild('window', { read: WindowComponent, static: false }) smartWindow!: WindowComponent;
	
	onButtonClick(event:any): void {
		const smartWindow = this.smartWindow;

		smartWindow.opened ? smartWindow.close() : smartWindow.open();
	}

	ngOnInit(): void {
		// onInit code.
	}

	ngAfterViewInit(): void {
		// afterViewInit code.
		this.init();
    }
		
	init(): void {
		// init code.

	}	
}

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-window as needed:

 <smart-button #button (onClick)="onButtonClick($event)" id="openButton">Open/Close</smart-button>
<smart-window #window [opened]="true" [label]="'Window 1'">
    <div id="article">
        <section>
             <h3>What is Lorem Ipsum?</h3>
            <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.
                Lorem Ipsum has been the industry's standard dummy text ever since the
                1500s, when an unknown printer took a galley of type and scrambled it to
                make a type specimen book. It has survived not only five centuries, but
                also the leap into electronic typesetting, remaining essentially unchanged.
                It was popularised in the 1960s with the release of Letraset sheets containing
                Lorem Ipsum passages, and more recently with desktop publishing software
                like Aldus PageMaker including versions of Lorem Ipsum.</p>
        </section>
        <section>
             <h3>Where does it come from?</h3>
            <p>Contrary to popular belief, Lorem Ipsum is not simply random text. It
                has roots in a piece of classical Latin literature from 45 BC, making it
                over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney
                College in Virginia, looked up one of the more obscure Latin words, consectetur,
                from a Lorem Ipsum passage, and going through the cites of the word in
                classical literature, discovered the undoubtable source. Lorem Ipsum comes
                from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The
                Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a
                treatise on the theory of ethics, very popular during the Renaissance.
                The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from
                a line in section 1.10.32. The standard chunk of Lorem Ipsum used since
                the 1500s is reproduced below for those interested. Sections 1.10.32 and
                1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced
                in their exact original form, accompanied by English versions from the
                1914 translation by H. Rackham.</p>
        </section>
    </div>
</smart-window>

6 NgModule bootstrap (also supported)

Same npm package and angular.json styles as steps 1-2. Put WindowModule 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 WindowModule from smart-webcomponents-angular/window 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 { WindowModule } from 'smart-webcomponents-angular/window';

@NgModule({
	declarations: [ AppComponent ],
	imports: [ BrowserModule, WindowModule ],
	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/.

Common Use Cases

  • Open modal dialog

    Show window as a modal overlay

    window.modal = true;
    window.open();
  • Handle close event

    Execute code when window closes

    smartWindow.addEventListener('close', () => {
      console.log('Window closed');
    });

Troubleshooting

How do I center the window?
Use windowParent = 'body' and set centered = true, or calculate position manually using viewport dimensions.
How do I prevent the window from being closed?
Handle the closing event and call e.preventDefault() to cancel the close action.

Accessibility

The Window 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.

Live demos

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.
