Mark a class as an Angular component through the @Component decorator:

The full list of @Component decorator properties is available on: Angular @Component Decorator API

Every jQWidgets Angular component has an [auto-create] attribute which determines whether the component is automatically created or is created on demand by API method call.
By default, the [auto-create] attribute value is true.


Create the AppComponent class.

The AppComponent class is used to instantiate the app. In some of the examples, we use @ViewChild and ngAfterViewInit.

Every component has a method setOptions which accepts a JSON object as an argument. This object contains component settings and you can use it to set a single or multiple properties dynamically.

Events

The itemClick event is triggered when a tag element is clicked.

Methods

To invoke methods, you can use the TagCloud reference.
 ( showItem(index) to show an item of the widget )  - this.myTagCloud.showItem(index).
