NgxMaterialToolsDemo

Updated to Angular 14

This is a set of custom directives lib for Angular Materials.

For now it contains only matInputCommified directive to be used with standard material matInput.

How to use

Install package

npm i ngx-material-tools

Import module

...
import {NgxMaterialToolsModule} from 'ngx-material-tools';

@NgModule({
...
  imports: [
...
    NgxMaterialToolsModule
  ],
...
})
export class AppModule { }

matInputCommified directive

Use matInputCommified directive together with matInput in Angular Reactive Forms

  <form [formGroup]="myForm" style="margin-top: 20px">
  <mat-form-field appearance="outline">
    <mat-label>Deposit Amount</mat-label>
    <input matInput
           matInputCommified
           formControlName="deposit"
           type="text"/>
  </mat-form-field>
</form>
>

scrollWatch directive

It allows to monitor if scroll appear on specific element (and change other elements layout respectively if needed). In particular: sometimes if scroll appears some elements alignment may need change (for examples labels above the container may be shifted to compensate scrollBar width)

<code class="code">
  Scroll status: {{scrollable.data | json}}
</code>
<section class="content" >
  <div class="header" [style.margin-right.px]="scrollable?.data?.verticalScrollBarWidth">
    Right aligned label
  </div>
  <div class="scrollable" scrollWatch #scrollable="scrollDetails" >
    <div class="some-long-text" *ngIf="showHideLongContent">
      Lorem ipsum dolor sit amet, consectetur adipisicing elit. Aliquid, amet aperiam asperiores, harum illo in iure nam non odit pariatur perferendis placeat quia quis reiciendis, rem saepe sequi temporibus unde?
      Lorem ipsum dolor sit amet, consectetur adipisicing elit. Aliquid, amet aperiam asperiores, harum illo in iure nam non odit pariatur perferendis placeat quia quis reiciendis, rem saepe sequi temporibus unde?
      Lorem ipsum dolor sit amet, consectetur adipisicing elit. Aliquid, amet aperiam asperiores, harum illo in iure nam non odit pariatur perferendis placeat quia quis reiciendis, rem saepe sequi temporibus unde?

    </div>
  </div>
</section>

1. Put attribute directive scrollWatch directive on specific html element
2. assign directive instance axported as scrollDetails to any ref variable (#scrollable="scrollDetails")
3. Use that variable in scope of template (for example to correct margin of element above)

scrollWatch directive demo

Provided data interface

export interface ContainsScrollEvent {
  hasHorizontalScroll: boolean;
  hasVerticalScroll: boolean;
  verticalScrollBarWidth: number;
  horizontalScrollBarWidth: number;
};

containsScroll pipe

You can also control specific container scrollBar visibility to a containsScroll pipe. It returns Observable which emit scrollBar data, so use Angular async to read them.

But I recommend to use scrollWatch directive since each time you use pipe in template - new instance of MutationObserver is created.

<section class="content" >

  Scroll status: {{(scrollable | containsScroll | async) | json}}

  <div class="header" [style.margin-right.px]="(scrollable | containsScroll | async)?.verticalScrollBarWidth || 0">
    Right aligned label
  </div>
  <div class="scrollable" #scrollable >
    <div class="some-long-text" *ngIf="showLongContent">
      Lorem ipsum dolor sit amet, consectetur adipisicing elit. Aliquid, amet aperiam asperiores, harum illo in iure nam non odit pariatur perferendis placeat quia quis reiciendis, rem saepe sequi temporibus unde?
      Lorem ipsum dolor sit amet, consectetur adipisicing elit. Aliquid, amet aperiam asperiores, harum illo in iure nam non odit pariatur perferendis placeat quia quis reiciendis, rem saepe sequi temporibus unde?
      Lorem ipsum dolor sit amet, consectetur adipisicing elit. Aliquid, amet aperiam asperiores, harum illo in iure nam non odit pariatur perferendis placeat quia quis reiciendis, rem saepe sequi temporibus unde?
