Displays a calendar month view that allows the selection of a date. The header displays the current month and year name, along with buttons to change the currently displayed month and year. The buttons in the header may be hidden, if desired.

The following example creates a date picker, sets the selected date, and listens for when the selection changes:

var datePicker = new DatePicker();
datePicker.selectedDate = new Date(2020, 1, 6);
datePicker.addEventListener(Event.CHANGE, (event:Event) -> {
	var datePicker = cast(event.currentTarget, DatePicker);
	trace("DatePicker changed: " + datePicker.selectedDate);
});
this.addChild(datePicker);

Events:

openfl.events.Event.CHANGE

Dispatched when DatePicker.selectedDate changes.

feathers.events.DatePickerEvent.ITEM_TRIGGER

Dispatched when the user taps or clicks an item renderer in the date picker. The pointer must remain within the bounds of the item renderer on release, or the gesture will be ignored.

read onlystyleContext:Class<IStyleObject>

The class used as the context for styling the component. If a subclass of a component should have different styles than its superclass, it should override the get_styleContext getter. However, if a subclass should continue using the same styles as its superclass, it happens automatically.

Available since

1.0.0

.

styleProvider:IStyleProvider

Typically used by the theme to provide styles to each component, but a custom style provider may be provided that will take precedence over the theme's style provider.

When a component initializes, its style provider sets properties that affect the component's visual appearance. If the style provider dispatches StyleProviderEvent.STYLES_CHANGE after the component has initialized, the original properties set by the style provider will be reset to their default values and before applying the new property values.

Setting the style provider or replacing an existing style provider before a component initializes will queue up the style changes until after initialization. Once a component initializes, the style provider may be changed, but the changes will be applied immediately. Similarly to when a style provider dispatcches StyleProviderEvent.STYLES_CHANGE, any properties that were set by the previous style provider will be reset to their default values before applying the new style provider.

If the themeEnabled property is false, the current theme's style provider will be ignored. However, if a custom style provider was provided from outside of the theme, it will still be used.

Inherited Methods

Defined by FeathersControl

private@:dox(show)initialize():Void

Called the first time that the UI control is added to the stage, and you should override this function to customize the initialization process. Do things like create children and set up event listeners. After this function is called, `FeathersEvent.INITIALIZE is dispatched.

The following example overrides initialization:

override private function initialize():Void {

Defined by ValidatingSprite

isInvalid(?flag:InvalidationFlag):Bool

Indicates whether the control is pending validation or not. By default, returns true if any invalidation flag has been set. If you pass in a specific flag, returns true only if that flag has been set (others may be set too, but it checks the specific flag only. If all flags have been marked as invalid, always returns true.

The following example invalidates a component:

component.setInvalid();
trace(component.isInvalid()); // true
Available since

1.0.0

.

runWithInvalidationFlagsOnly(callback:() ‑> Void):Void

Calls a function that temporarily limits setInvalid() calls to setting invalidation flags only, and the control will not be added to the validation queue. In other words, setInvalid() calls will work similarly to setInvalidationFlag() instead.

Typically, this method should be called only during validation. If called outside of update(), the component's validation may be delayed until a future call to setInvalid().

Available since

1.2.0

.

runWithoutInvalidation(callback:() ‑> Void):Void

Calls a function that temporarily disables invalidation. In other words, calls to setInvalid() will be ignored until the function returns.

Available since

1.0.0

.

setInvalid(?flag:InvalidationFlag):Void

Call this function to tell the UI control that a redraw is pending. The redraw will happen immediately before OpenFL renders the UI control to the screen. The validation system exists to ensure that multiple properties can be set together without redrawing multiple times in between each property change.

If you cannot wait until later for the validation to happen, you can call validate() to redraw immediately. As an example, you might want to validate immediately if you need to access the correct width or height values of the UI control, since these values are calculated during validation.

The following example invalidates a component:

component.setInvalid();
trace(component.isInvalid()); // true
Available since

1.0.0

.

private@:dox(show)setInvalidationFlag(flag:InvalidationFlag):Void

Sets an invalidation flag. This will not add the component to the validation queue. It only sets the flag. A subclass might use this function during draw() to manipulate the flags that its superclass sees.

Available since

1.0.0

.

See also:

private@:dox(show)update():Void

Override to customize layout and to adjust properties of children. Called when the component validates, if any flags have been marked to indicate that validation is pending.

	super.update();

}
