bind( bindProperties ) → MultiBindChain
See source
Binds observable properties to other objects implementing the Observable interface.

Read more in the dedicated guide covering the topic of property bindings with some additional examples.

Consider two objects: a button and an associated command (both Observable).

A simple property binding could be as follows:
```
button.bind( 'isEnabled' ).to( command, 'isEnabled' );
```
or even shorter:
```
button.bind( 'isEnabled' ).to( command );
```
which works in the following way:
- button.isEnabled instantly equals command.isEnabled,
- whenever command.isEnabled changes, button.isEnabled will immediately reflect its value.
Note: To release the binding, use unbind.

You can also "rename" the property in the binding by specifying the new name in the to() chain:
```
button.bind( 'isEnabled' ).to( command, 'isWorking' );
```
It is possible to bind more than one property at a time to shorten the code:
```
button.bind( 'isEnabled', 'value' ).to( command );
```
which corresponds to:
```
button.bind( 'isEnabled' ).to( command );
button.bind( 'value' ).to( command );
```
The binding can include more than one observable, combining multiple data sources in a custom callback:
```
button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible',
	( isCommandEnabled, isUIVisible ) => isCommandEnabled && isUIVisible );
```
Using a custom callback allows processing the value before passing it to the target property:
```
button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );
```
It is also possible to bind to the same property in an array of observables. To bind a button to multiple commands (also Observables) so that each and every one of them must be enabled for the button to become enabled, use the following code:
```
button.bind( 'isEnabled' ).toMany( [ commandA, commandB, commandC ], 'isEnabled',
	( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled && isBEnabled && isCEnabled );
```
Parameters

bindProperties : Array<'name' | 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'element' | 'template' | 'isRendered' | 'locale' | 't' | 'viewUid' | 'bindTemplate' | 'createCollection' | 'registerChild' | 'deregisterChild' | 'setTemplate' | 'extendTemplate' | 'render' | 'destroy' | 'isFocused' | 'hasExternalElement'>

`createCollection( [ views ] ) → ViewCollection<T>`

See source

Creates a new collection of views, which can be used as children of this view.

class SampleView extends View {
	constructor( locale ) {
		super( locale );

		const child = new ChildView( locale );
		this.items = this.createCollection( [ child ] );
 *
		this.setTemplate( {
			tag: 'p',

			// `items` collection will render here.
			children: this.items
		} );
	}
}

const view = new SampleView( locale );
view.render();

// It will append <p><child#element></p> to the <body>.
document.body.appendChild( view.element );

Type parameters

T : extends [object Object] = default

Parameters

[ views ] : Iterable<T>: Initial views of the collection.

Returns

ViewCollection<T>: A new collection of view instances.

inherited
decorate( methodName ) → void
See source
Turns the given methods of this object into event-based ones. This means that the new method will fire an event (named after the method) and the original action will be plugged as a listener to that event.

Read more in the dedicated guide covering the topic of decorating methods with some additional examples.

Decorating the method does not change its behavior (it only adds an event), but it allows to modify it later on by listening to the method's event.

For example, to cancel the method execution the event can be stopped:
```
class Foo extends ObservableMixin() {
	constructor() {
		super();
		this.decorate( 'method' );
	}

	method() {
		console.log( 'called!' );
	}
}

const foo = new Foo();
foo.on( 'method', ( evt ) => {
	evt.stop();
}, { priority: 'high' } );

foo.method(); // Nothing is logged.
```
Note: The high priority listener has been used to execute this particular callback before the one which calls the original method (which uses the "normal" priority).

It is also possible to change the returned value:
```
foo.on( 'method', ( evt ) => {
	evt.return = 'Foo!';
} );

foo.method(); // -> 'Foo'
```
Finally, it is possible to access and modify the arguments the method is called with:
```
method( a, b ) {
	console.log( `${ a }, ${ b }`  );
}

// ...

foo.on( 'method', ( evt, args ) => {
	args[ 0 ] = 3;

	console.log( args[ 1 ] ); // -> 2
}, { priority: 'high' } );

foo.method( 1, 2 ); // -> '3, 2'
```
Parameters

methodName : 'name' | 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'element' | 'template' | 'isRendered' | 'locale' | 't' | 'viewUid' | 'bindTemplate' | 'createCollection' | 'registerChild' | 'deregisterChild' | 'setTemplate' | 'extendTemplate' | 'render' | 'destroy' | 'isFocused' | 'hasExternalElement'

Name of the method to decorate.

Returns

delegate( events ) → EmitterMixinDelegateChain
See source
Delegates selected events to another Emitter. For instance:
```
emitterA.delegate( 'eventX' ).to( emitterB );
emitterA.delegate( 'eventX', 'eventY' ).to( emitterC );
```
then eventX is delegated (fired by) emitterB and emitterC along with data:
```
emitterA.fire( 'eventX', data );
```
and eventY is delegated (fired by) emitterC along with data:
```
emitterA.fire( 'eventY', data );
```
Parameters

events : Array<string>

Event names that will be delegated to another emitter.

Returns

EmitterMixinDelegateChain
inherited
deregisterChild( children ) → void
See source

Parameters

children : View<HTMLElement> | Iterable<View<HTMLElement>>

Child views to be removed.

Returns

void

Related:
- EditableUIView#registerChild
destroy() → void
See source
Recursively destroys the view instance and child views added by registerChild and residing in collections created by the createCollection.

Destruction disables all event listeners:
- created on the view, e.g. view.on( 'event', () => {} ),
- defined in the template for DOM events.
Returns

void
inherited
extendTemplate( definition ) → void
See source
Extends the template of the view with with given definition.

A shorthand for:

Definition which extends the template.

Returns

void
inherited
fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]

inherited
listenTo( emitter, event, callback, [ options ] ) → void
See source
Registers a callback function to be executed when an event is fired in a specific (emitter) object.

Events can be grouped in namespaces using :. When namespaced event is fired, it additionally fires all callbacks for that namespace.
```
// myEmitter.on( ... ) is a shorthand for myEmitter.listenTo( myEmitter, ... ).
myEmitter.on( 'myGroup', genericCallback );
myEmitter.on( 'myGroup:myEvent', specificCallback );

// genericCallback is fired.
myEmitter.fire( 'myGroup' );
// both genericCallback and specificCallback are fired.
myEmitter.fire( 'myGroup:myEvent' );
// genericCallback is fired even though there are no callbacks for "foo".
myEmitter.fire( 'myGroup:foo' );
```
An event callback can stop the event and set the return value of the fire method.

Type parameters

TEvent : extends BaseEvent

The type describing the event. See BaseEvent.

Parameters

emitter : Emitter

The object that fires the event.

event : TEvent[ 'name' ]

Registers a new child view under the view instance. Once registered, a child view is managed by its parent, including rendering and destruction.

To revert this, use deregisterChild.

class SampleView extends View {
	constructor( locale ) {
		super( locale );

		this.childA = new SomeChildView( locale );
		this.childB = new SomeChildView( locale );

		this.setTemplate( { tag: 'p' } );

		this.registerChild( [ this.childA, this.childB ] );
	}

	render() {
		super.render();

		this.element.appendChild( this.childA.element );
		this.element.appendChild( this.childB.element );
	}
}

const view = new SampleView( locale );

view.render();

// Will append <p><childA#element><b></b><childB#element></p>.
document.body.appendChild( view.element );

Note: There's no need to add child views if they're already referenced in the template:

class SampleView extends View {
	constructor( locale ) {
		super( locale );

		this.childA = new SomeChildView( locale );
		this.childB = new SomeChildView( locale );

		this.setTemplate( {
			tag: 'p',

 * 			// These children will be added automatically. There's no

Renders the view by either applying the template to the existing _editableElement or assigning element as _editableElement.

Returns

void
inherited
set( values ) → void
See source
Creates and sets the value of an observable properties of this object. Such a property becomes a part of the state and is observable.

It accepts a single object literal containing key/value pairs with properties to be set.

This method throws the observable-set-cannot-override error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means that foo.set( 'bar', 1 ) may be slightly slower than foo.bar = 1.

In TypeScript, those properties should be declared in class using declare keyword. In example:
```
public declare myProp1: number;
public declare myProp2: string;

constructor() {
	this.set( {
		'myProp1: 2,
		'myProp2: 'foo'
	} );
}
```
Parameters

values : object

An object with name=>value pairs.

Returns

void

Fired when a property value is going to be set but is not set yet (before the change event is fired).

You can control the final value of the property by using the event's return property.
```
observable.set( 'prop', 1 );

observable.on<ObservableSetEvent<number>>( 'set:prop', ( evt, propertyName, newValue, oldValue ) => {
	console.log( `Value is going to be changed from ${ oldValue } to ${ newValue }` );
	console.log( `Current property value is ${ observable[ propertyName ] }` );

	// Let's override the value.
	evt.return = 3;
} );

observable.on<ObservableChangeEvent<number>>( 'change:prop', ( evt, propertyName, newValue, oldValue ) => {
	console.log( `Value has changed from ${ oldValue } to ${ newValue }` );
} );

observable.prop = 2; // -> 'Value is going to be changed from 1 to 2'
                     // -> 'Current property value is 1'
                     // -> 'Value has changed from 1 to 3'
```
Note: The event is fired even when the new value is the same as the old value.

Parameters

eventInfo : EventInfo

An object containing information about the fired event.

name : string

The property name.

value : TValue

The new property value.

oldValue : TValue

The previous property value.
