bind( bindProperties ) → MultiBindChain
module:ui/colorgrid/colortileview~ColorTileView#bind:MANY_BIND
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 associatedcommand
(bothObservable
).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 equalscommand.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 (alsoObservables
) 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<'type' | 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'element' | 'label' | 'template' | 'focus' | 'ariaLabel' | 'role' | 'children' | 'isRendered' | 'locale' | 't' | 'viewUid' | 'bindTemplate' | 'createCollection' | 'registerChild' | 'deregisterChild' | 'setTemplate' | 'extendTemplate' | 'render' | 'destroy' | 'class' | 'color' | 'isVisible' | 'tooltip' | 'tooltipPosition' | '_ariaPressed' | 'labelView' | 'iconView' | 'keystrokeView' | 'labelStyle' | 'icon' | 'isEnabled' | 'isOn' | 'isToggleable' | 'keystroke' | 'tabindex' | 'withText' | 'withKeystroke' | 'ariaLabelledBy' | '_ariaChecked' | '_tooltipString' | 'hasBorder'>

createCollection( [ views ] ) → ViewCollection<T>
module:ui/colorgrid/colortileview~ColorTileView#createCollection
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.
-
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 : 'type' | 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'element' | 'label' | 'template' | 'focus' | 'ariaLabel' | 'role' | 'children' | 'isRendered' | 'locale' | 't' | 'viewUid' | 'bindTemplate' | 'createCollection' | 'registerChild' | 'deregisterChild' | 'setTemplate' | 'extendTemplate' | 'render' | 'destroy' | 'class' | 'color' | 'isVisible' | 'tooltip' | 'tooltipPosition' | '_ariaPressed' | 'labelView' | 'iconView' | 'keystrokeView' | 'labelStyle' | 'icon' | 'isEnabled' | 'isOn' | 'isToggleable' | 'keystroke' | 'tabindex' | 'withText' | 'withKeystroke' | 'ariaLabelledBy' | '_ariaChecked' | '_tooltipString' | 'hasBorder'

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' } ); // Register the children. 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 * // need to call
registerChild
for any of them. children: [ this.childA, this.childB ] } ); } // ... }Parameters
Returns
void
-
render() → void
module:ui/colorgrid/colortileview~ColorTileView#render
Recursively renders the view.
Once the view is rendered:
- the
element
becomes an HTML element out oftemplate
, - the
isRendered
flag is settrue
.
Note: The children of the view:
- defined directly in the
template
- residing in collections created by the
createCollection
method, - and added by
registerChild
are also rendered in the process.
In general,
render()
method is the right place to keep the code which refers to theelement
and should be executed at the very beginning of the view's life cycle.It is possible to
extend
thetemplate
before the view is rendered. To allow an early customization of the view (e.g. by its parent), such references should be done inrender()
.class SampleView extends View { constructor() { this.setTemplate( { // ... } ); }, render() { // View#element becomes available. super.render(); // The "scroll" listener depends on #element. this.listenTo( window, 'scroll', () => { // A reference to #element would render the #template and make it non-extendable. if ( window.scrollY > 0 ) { this.element.scrollLeft = 100; } else { this.element.scrollLeft = 0; } } ); } } const view = new SampleView(); // Let's customize the view before it gets rendered. view.extendTemplate( { attributes: { class: [ 'additional-class' ] } } ); // Late rendering allows customization of the view. view.render();
Returns
void
- the
-
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 thatfoo.set( 'bar', 1 )
may be slightly slower thanfoo.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.

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 thatfoo.set( 'bar', 1 )
may be slightly slower thanfoo.bar = 1
.In TypeScript, those properties should be declared in class using
declare
keyword. In example:public declare myProp: number; constructor() { this.set( 'myProp', 2 ); }
Type parameters

name : K
The property's name.
value : ColorTileView[ K ]

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.
