The <mat-progress-spinner>, an Angular Directive, is used to show a progress spinner with material styling.
In this chapter, we will showcase the configuration required to draw a deterministic as well as indeterministic progress spinner using Angular Material.
Follow the following steps to update the Angular application we created in Angular 6 - Project Setup chapter −
Step | Description |
---|---|
1 | Create a project with a name materialApp as explained in the Angular 6 - Project Setup chapter. |
2 | Modify app.module.ts, app.component.ts, app.component.css and app.component.html as explained below. Keep rest of the files unchanged. |
3 | Compile and run the application to verify the result of the implemented logic. |
Following is the content of the modified module descriptor app.module.ts.
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import {BrowserAnimationsModule} from '@angular/platform-browser/animations'; import {MatProgressSpinnerModule, MatRadioModule, MatSliderModule} from '@angular/material' import {FormsModule, ReactiveFormsModule} from '@angular/forms'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, BrowserAnimationsModule, MatProgressSpinnerModule, MatRadioModule, MatSliderModule, FormsModule, ReactiveFormsModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
Following is the content of the modified ts file app.component.css.
.tp-section { display: flex; align-content: center; align-items: center; height: 60px; } .tp-margin { margin: 0 10px; }
Following is the content of the modified HTML host file app.component.html.
<section class = "tp-section"> <label class = "tp-margin">Color:</label> <mat-radio-group [(ngModel)] = "color"> <mat-radio-button class = "tp-margin" value = "primary"> Primary </mat-radio-button> <mat-radio-button class = "tp-margin" value = "accent"> Accent </mat-radio-button> <mat-radio-button class = "tp-margin" value = "warn"> Warn </mat-radio-button> </mat-radio-group> </section> <section class = "tp-section"> <label class = "tp-margin">Mode:</label> <mat-radio-group [(ngModel)] = "mode"> <mat-radio-button class = "tp-margin" value = "determinate"> Determinate </mat-radio-button> <mat-radio-button class = "tp-margin" value = "indeterminate"> Indeterminate </mat-radio-button> </mat-radio-group> </section> <section class = "tp-section" *ngIf = "mode === 'determinate'"> <label class = "tp-margin">Progress:</label> <mat-slider class = "tp-margin" [(ngModel)] = "value"></mat-slider> </section> <section class = "tp-section"> <label class = "tp-margin">Mode: {{mode}}</label> <mat-progress-spinner class = "tp-margin" [color] = "color" [mode] = "mode" [value] = "value"> </mat-progress-spinner> </section>
Following is the content of the modified ts file app.component.ts.
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'materialApp'; color = 'primary'; mode = 'determinate'; value = 50; }
Verify the result.
