@ckeditor/ckeditor5-table/src/tablecellproperties/commands/tablecellborderstylecommand

class
See source

The table cell border style command.

The command is registered by the TableCellPropertiesEditing as the 'tableCellBorderStyle' editor command.

To change the border style of selected cells, execute the command:

editor.execute( 'tableCellBorderStyle', {
  value: 'dashed'
} );

Properties

  • inherited

    affectsData : boolean

    See source

    A flag indicating whether a command execution changes the editor data or not.

    Commands with affectsData set to false will not be automatically disabled in the read-only mode and other editor modes with restricted user write permissions.

    Note: You do not have to set it for your every command. It is true by default.

    Parameters

    affectsData : boolean

  • readonly inherited

    attributeName : string

    See source

    The attribute that will be set by the command.

  • readonly inherited

    editor : Editor

    See source

    The editor on which this command will be used.

  • inherited observable

    isEnabled : boolean

    See source

    Flag indicating whether a command is enabled or disabled. A disabled command will do nothing when executed.

    A given command class should control this value by overriding the refresh() method.

    It is possible to disable a command "from outside" using forceDisabled method.

  • inherited observable

    value : unknown

    See source

    The value of the command. A given command class should define what it represents for it.

    For example, the 'bold' command's value indicates whether the selection starts in a bolded text. And the value of the 'link' command may be an object with link details.

    It is possible for a command to have no value (e.g. for stateless actions such as 'uploadImage').

    A given command class should control this value by overriding the refresh() method.

  • protected readonly inherited

    _defaultValue : string

    See source

    The default value for the attribute.

  • protected inherited

    _isEnabledBasedOnSelection : boolean

    See source

    A flag indicating whether a command's isEnabled state should be changed depending on where the document selection is placed.

    By default, it is set to true. If the document selection is placed in a non-editable place (such as non-editable root), the command becomes disabled.

    The flag should be changed to false in a concrete command's constructor if the command should not change its isEnabled accordingly to the document selection.

Methods

  • constructor( editor, defaultValue )

    See source

    Creates a new TableCellBorderStyleCommand instance.

    Parameters

    editor : Editor

    An editor in which this command will be used.

    defaultValue : string

    The default value of the attribute.

  • inherited

    bind( bindProperty1, bindProperty2 ) → DualBindChain<K1, TableCellBorderStyleCommand[ K1 ], K2, TableCellBorderStyleCommand[ K2 ]>

    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 );

    Type parameters

    K1
    K2

    Parameters

    bindProperty1 : K1

    Observable property that will be bound to other observable(s).

    bindProperty2 : K2

    Observable property that will be bound to other observable(s).

    Returns

    DualBindChain<K1, TableCellBorderStyleCommand[ K1 ], K2, TableCellBorderStyleCommand[ K2 ]>

    The bind chain with the to() and toMany() methods.

  • inherited

    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' | 'value' | 'execute' | 'isEnabled' | 'affectsData' | 'attributeName' | 'refresh' | '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

  • inherited

    destroy() → void

    See source

    Destroys the command.

    Returns

    void

  • inherited

    execute( options = { [options.batch], [options.value] } ) → void

    See source

    Executes the command.

    Parameters

    options : object
    Properties
    [ options.batch ] : Batch

    Pass the model batch instance to the command to aggregate changes, for example to allow a single undo step for multiple executions.

    [ options.value ] : string | number

    If set, the command will set the attribute on selected table cells. If it is not set, the command will remove the attribute from the selected table cells.

    Defaults to {}

    Returns

    void

    Fires

  • 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 command.

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

    Disabling and enabling a command:

    command.isEnabled; // -> true
command.forceDisabled( 'MyFeature' );
command.isEnabled; // -> false
command.clearForceDisabled( 'MyFeature' );
command.isEnabled; // -> true

    Command disabled by multiple features:

    command.forceDisabled( 'MyFeature' );
command.forceDisabled( 'OtherFeature' );
command.clearForceDisabled( 'MyFeature' );
command.isEnabled; // -> false
command.clearForceDisabled( 'OtherFeature' );
command.isEnabled; // -> true

    Multiple disabling with the same identifier is redundant:

    command.forceDisabled( 'MyFeature' );
command.forceDisabled( 'MyFeature' );
command.clearForceDisabled( 'MyFeature' );
command.isEnabled; // -> true

    Note: some commands or algorithms may have more complex logic when it comes to enabling or disabling certain commands, so the command might be still disabled after clearForceDisabled was used.

    Parameters

    id : string

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

    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.

    Additional options.

    Returns

    void

  • inherited

    off( event, callback ) → void

    See source

    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>

  • 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.

  • inherited

    refresh() → void

    See source

    Refreshes the command. The command should update its isEnabled and value properties in this method.

    This method is automatically called when any changes are applied to the document.

    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

    set( name, value ) → void

    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.
