WidgetTypeAround (widget/widgettypearound)

@ckeditor/ckeditor5-widget/src/widgettypearound/widgettypearound

class

A plugin that allows users to type around widgets where normally it is impossible to place the caret due to limitations of web browsers. These "tight spots" occur, for instance, before (or after) a widget being the first (or last) child of its parent or between two block widgets.

This plugin extends the Widget plugin and injects the user interface with two buttons into each widget instance in the editor. Each of the buttons can be clicked by the user if the widget is next to the "tight spot". Once clicked, a paragraph is created with the selection anchored in it so that users can type (or insert content, paste, etc.) straight away.

Properties

readonly inherited
editor : Editor
See source
The editor instance.

Note that most editors implement the ui property. However, editors with an external UI (i.e. Bootstrap-based) or a headless editor may not have this property or throw an error when accessing it.

Because of above, to make plugins more universal, it is recommended to split features into:
- The "editing" part that uses the Editor class without ui property.
- The "UI" part that uses the Editor class and accesses ui property.
inherited observable
isEnabled : boolean
See source
Flag indicating whether a plugin is enabled or disabled. A disabled plugin will not transform text.

Plugin can be simply disabled like that:
```
// Disable the plugin so that no toolbars are visible.
editor.plugins.get( 'TextTransformation' ).isEnabled = false;
```
You can also use forceDisabled method.
private
_currentFakeCaretModelElement : null | Element

See source
A reference to the model widget element that has the fake caret active on either side of it. It is later used to remove CSS classes associated with the fake caret when the widget no longer needs it.

bind( bindProperty ) → SingleBindChain<K, WidgetTypeAround[ K ]>
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 );
```

clearForceDisabled( id ) → void

See source
Clears forced disable previously set through forceDisabled. See forceDisabled.

Parameters

id : string

Unique identifier, equal to the one passed in forceDisabled call.

Returns

void
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 : 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'destroy' | 'init' | 'isEnabled' | 'editor' | 'forceDisabled' | 'clearForceDisabled'

Name of the method to decorate.

Returns

void
inherited
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
destroy() → void

See source
Destroys the plugin.

Note: This method is optional. A plugin instance does not need to have it defined.

Returns

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

See source
Fires an event, executing all callbacks registered for it.

The first parameter passed to callbacks is an EventInfo object, followed by the optional args provided in the fire() method call.

Type parameters

TEvent : extends BaseEvent

The type describing the event. See BaseEvent.

Parameters

eventOrInfo : GetNameOrEventInfo<TEvent>

The name of the event or EventInfo object if event is delegated.

args : TEvent[ 'args' ]

Additional arguments to be passed to the callbacks.

Returns

GetEventInfo<TEvent>[ 'return' ]

By default the method returns undefined. However, the return value can be changed by listeners through modification of the evt.return's property (the event info is the first param of every callback).
inherited
forceDisabled( id ) → void
See source
Disables the plugin.

Plugin may be disabled by multiple features or algorithms (at once). When disabling a plugin, unique id should be passed (e.g. feature name). The same identifier should be used when enabling back the plugin. The plugin becomes enabled only after all features enabled it back.

Disabling and enabling a plugin:
```
plugin.isEnabled; // -> true
plugin.forceDisabled( 'MyFeature' );
plugin.isEnabled; // -> false
plugin.clearForceDisabled( 'MyFeature' );
plugin.isEnabled; // -> true
```
Plugin disabled by multiple features:
```
plugin.forceDisabled( 'MyFeature' );
plugin.forceDisabled( 'OtherFeature' );
plugin.clearForceDisabled( 'MyFeature' );
plugin.isEnabled; // -> false
plugin.clearForceDisabled( 'OtherFeature' );
plugin.isEnabled; // -> true
```
Multiple disabling with the same identifier is redundant:
```
plugin.forceDisabled( 'MyFeature' );
plugin.forceDisabled( 'MyFeature' );
plugin.clearForceDisabled( 'MyFeature' );
plugin.isEnabled; // -> true
```
Note: some plugins or algorithms may have more complex logic when it comes to enabling or disabling certain plugins, so the plugin might be still disabled after clearForceDisabled was used.

Parameters

id : string

Unique identifier for disabling. Use the same id when enabling back the plugin.

Returns

void
init() → void

See source

Returns

void
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' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
off( event, callback ) → void

See source
Stops executing the callback on the given event. Shorthand for this.stopListening( this, event, callback ).

Parameters

event : string

The name of the event.

callback : Function

The function to stop being called.

Returns

void
inherited
on( event, callback, [ options ] ) → void

See source
Registers a callback function to be executed when an event is fired.

Shorthand for this.listenTo( this, event, callback, options ) (it makes the emitter listen on itself).

Type parameters

TEvent : extends BaseEvent

The type descibing the event. See BaseEvent.

Parameters

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
once( event, callback, [ options ] ) → void

See source
Registers a callback function to be executed on the next time the event is fired only. This is similar to calling on followed by off in the callback.

Type parameters

TEvent : extends BaseEvent

The type descibing the event. See BaseEvent.

Parameters

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

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

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 myProp: number;

constructor() {
	this.set( 'myProp', 2 );
}
```
Type parameters

K

Parameters

name : K

The property's name.

value : WidgetTypeAround[ K ]

The property's value.

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
inherited
stopDelegating( [ event ], [ emitter ] ) → void
See source
Stops delegating events. It can be used at different levels:
- To stop delegating all events.
- To stop delegating a specific event to all emitters.
- To stop delegating a specific event to a specific emitter.
Parameters

[ event ] : string

The name of the event to stop delegating. If omitted, stops it all delegations.

[ emitter ] : Emitter

(requires event) The object to stop delegating a particular event to. If omitted, stops delegation of event to all emitters.

Returns

void
inherited
stopListening( [ emitter ], [ event ], [ callback ] ) → void

- To stop listening to all events fired by a specific object.
- To stop listening to all events fired by all objects.
Parameters

[ emitter ] : Emitter

The object to stop listening to. If omitted, stops it for all objects.

[ event ] : string

(Requires the emitter) The name of the event to stop listening to. If omitted, stops it for all events from emitter.

[ callback ] : Function

(Requires the event) The function to be removed from the call list for the given event.

Returns

void
inherited
unbind( unbindProperties ) → void
See source
Removes the binding created with bind.
```
// Removes the binding for the 'a' property.
A.unbind( 'a' );

// Removes bindings for all properties.

Observable properties to be unbound. All the bindings will be released if no properties are provided.

Returns

void
private
_enableDeleteContentIntegration() → void

See source
Attaches the event-deleteContent event listener to block the event when the fake caret is active.

This is required for cases that trigger model.deleteContent() before calling model.insertContent() like, for instance, plain text pasting.

Returns

void
private
_enableDeleteIntegration() → void

See source
It creates a "delete" event listener on the view document to handle cases when the Delete or Backspace is pressed and the fake caret is currently active.

The fake caret should create an illusion of a real browser caret so that when it appears before or after a widget, pressing Delete or Backspace should remove a widget or delete the content before or after a widget (depending on the content surrounding the widget).

Returns

void
private
_enableInsertContentIntegration() → void

See source
Attaches the event-insertContent event listener that, for instance, allows the user to paste content near a widget when the fake caret is first activated using the arrow keys.

The content is inserted according to the widget-type-around selection attribute (see _handleArrowKeyPress).

Returns

void
private
_enableInsertObjectIntegration() → void

See source
Attaches the event-insertObject event listener that modifies the options.findOptimalPositionparameter to position of fake caret in relation to selected element to reflect user's intent of desired insertion position.

The object is inserted according to the widget-type-around selection attribute (see _handleArrowKeyPress).

Returns

void
private
_enableInsertingParagraphsOnButtonClick() → void

See source
Registers a mousedown listener for the view document which intercepts events coming from the widget type around UI, which happens when a user clicks one of the buttons that insert a paragraph next to a widget.

Returns

void
private
_enableInsertingParagraphsOnEnterKeypress() → void
See source
Creates the Enter key listener on the view document that allows the user to insert a paragraph near the widget when either:
- The fake caret was first activated using the arrow keys,
- The entire widget is selected in the model.
In the first case, the new paragraph is inserted according to the widget-type-around selection attribute (see _handleArrowKeyPress).

In the second case, the new paragraph is inserted based on whether a soft (Shift+Enter) keystroke was pressed or not.

Returns

void
private
_enableInsertingParagraphsOnTypingKeystroke() → void

See source
Similar to the _enableInsertingParagraphsOnEnterKeypress, it allows the user to insert a paragraph next to a widget when the fake caret was activated using arrow keys but it responds to typing instead of Enter.

Listener enabled by this method will insert a new paragraph according to the widget-type-around model selection attribute as the user simply starts typing, which creates the impression that the fake caret behaves like a real one rendered by the browser (AKA your text appears where the caret was).

Note: At the moment this listener creates 2 undo steps: one for the insertParagraph command and another one for actual typing. It is not a disaster but this may need to be fixed sooner or later.

Returns

void
private
_enableTypeAroundFakeCaretActivationUsingKeyboardArrows() → void
See source
Brings support for the fake caret that appears when either:
- the selection moves to a widget from a position next to it using arrow keys,
- the arrow key is pressed when the widget is already selected.
The fake caret lets the user know that they can start typing or just press Enter to insert a paragraph at the position next to a widget as suggested by the fake caret.

The fake caret disappears when the user changes the selection or the editor gets blurred.

The whole idea is as follows:
1. A user does one of the 2 scenarios described at the beginning.
2. The "keydown" listener is executed and the decision is made whether to show or hide the fake caret.
3. If it should show up, the widget-type-around model selection attribute is set indicating on which side of the widget it should appear.
4. The selection dispatcher reacts to the selection attribute and sets CSS classes responsible for the fake caret on the view widget.
5. If the fake caret should disappear, the selection attribute is removed and the dispatcher does the CSS class clean-up in the view.
6. Additionally, change:range and FocusTracker#isFocused listeners also remove the selection attribute (the former also removes widget CSS classes).
Returns

void
private
_enableTypeAroundUIInjection() → void

See source
Creates a listener in the editing conversion pipeline that injects the widget type around UI into every single widget instance created in the editor.

The UI is delivered as a UIElement wrapper which renders DOM buttons that users can use to insert paragraphs.

Returns

void
private
_handleArrowKeyPress( evt, domEventData ) → void

See source
A listener executed on each "keydown" in the view document, a part of _enableTypeAroundFakeCaretActivationUsingKeyboardArrows.

It decides whether the arrow keypress should activate the fake caret or not (also whether it should be deactivated).

The fake caret activation is done by setting the widget-type-around model selection attribute in this listener, and stopping and preventing the event that would normally be handled by the widget plugin that is responsible for the regular keyboard navigation near/across all widgets (that includes inline widgets, which are ignored by the widget type around plugin).

Parameters

evt : BubblingEventInfo<'arrowKey', unknown>

domEventData : object

Returns

void
private
_handleArrowKeyPressOnSelectedWidget( isForward ) → boolean

See source
Handles the keyboard navigation on "keydown" when a widget is currently selected and activates or deactivates the fake caret for that widget, depending on the current value of the widget-type-around model selection attribute and the direction of the pressed arrow key.

Parameters

isForward : boolean

true when the pressed arrow key was responsible for the forward model selection movement as in isForwardArrowKeyCode.

Returns

boolean

Returns true when the keypress was handled and no other keydown listener of the editor should process the event any further. Returns false otherwise.
private
_handleArrowKeyPressWhenNonCollapsedSelection( isForward ) → boolean

See source
Handles the keyboard navigation on "keydown" when a widget is currently selected (together with some other content) and the widget is the first or last element in the selection. It activates or deactivates the fake caret for that widget.

Parameters

isForward : boolean

true when the pressed arrow key was responsible for the forward model selection movement as in isForwardArrowKeyCode.

Returns

boolean

Returns true when the keypress was handled and no other keydown listener of the editor should process the event any further. Returns false otherwise.
private
_handleArrowKeyPressWhenSelectionNextToAWidget( isForward ) → boolean

See source
Handles the keyboard navigation on "keydown" when no widget is selected but the selection is directly next to one and upon the fake caret should become active for this widget upon arrow keypress (AKA entering/selecting the widget).

Note: This code mirrors the implementation from the widget plugin but also adds the selection attribute. Unfortunately, there is no safe way to let the widget plugin do the selection part first and then just set the selection attribute here in the widget type around plugin. This is why this code must duplicate some from the widget plugin.

Parameters

isForward : boolean

true when the pressed arrow key was responsible for the forward model selection movement as in isForwardArrowKeyCode.

Returns

boolean

Returns true when the keypress was handled and no other keydown listener of the editor should process the event any further. Returns false otherwise.
private
_insertParagraph( widgetModelElement, position ) → void

See source
Inserts a new paragraph next to a widget element with the selection anchored in it.

Note: This method is heavily user-oriented and will both focus the editing view and scroll the viewport to the selection in the inserted paragraph.

Parameters

widgetModelElement : Element

The model widget element next to which a paragraph is inserted.

position : 'before' | 'after'

The position where the paragraph is inserted. Either 'before' or 'after' the widget.

Returns

void
private
_insertParagraphAccordingToFakeCaretPosition() → boolean

See source
Similar to _insertParagraph, this method inserts a paragraph except that it does not expect a position. Instead, it performs the insertion next to a selected widget according to the widget-type-around model selection attribute value (fake caret position).

Because this method requires the widget-type-around attribute to be set, the insertion can only happen when the widget's fake caret is active (e.g. activated using the keyboard).

Returns

boolean

Returns true when the paragraph was inserted (the attribute was present) and false otherwise.
private
_listenToIfEnabled( emitter, event, callback, [ options ] ) → void

See source
A wrapper for the listenTo method that executes the callbacks only when the plugin is enabled.

Type parameters

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

Parameters

eventInfo : EventInfo

An object containing information about the fired event.

name : string

Name of the changed property (isEnabled).

value : boolean

New value of the isEnabled property with given key or null, if operation should remove property.

oldValue : boolean

inherited
set:{property}( eventInfo, name, value, oldValue )
See source
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.
