A container that supports navigation between views using a PageIndicator.

The following example creates a page navigator and adds some items:

var navigator = new PageNavigator();
navigator.dataProvider = new ArrayCollection([
	PageItem.withClass(WizardView1),
	PageItem.withClass(WizardView1),
	PageItem.withClass(WizardView3)
]);
addChild(this.navigator);

See also:

read onlytransitionActive:Bool

Indicates whether the navigator is currently transitioning between views or not.

Defined by FeathersControl

read onlycreated:Bool

Determines if the component has been initialized and validated for the first time.

In the following example, we check if the component is created or not, and we listen for an event if it isn't:

if(!control.created)
{
	control.addEventListener(FeathersEventType.CREATION_COMPLETE, creationCompleteHandler);
}

@:value(null)@:styledisabledAlpha:Null<Float> = null

When disabledAlpha is not null, sets the alpha property to this value when the the enabled property is set to false.

@stylefocusRectSkin:DisplayObject

An optional skin to display when an IFocusObject component receives focus.

read onlyinitialized:Bool

Determines if the component has been initialized yet. The initialize() function is called one time only, when the Feathers UI control is added to the display list for the first time.

In the following example, we check if the component is initialized or not, and we listen for an event if it isn't initialized:

if(!control.initialized)
{
	control.addEventListener(FeathersEvent.INITIALIZE, initializeHandler);
}

See also:

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

When a component initializes, a style provider may be used to set properties that affect the component's visual appearance.

You can set or replace an existing style provider at any time before a component initializes without immediately affecting the component's visual appearance. After the component initializes, the style provider may still be changed, and any properties that were set by the previous style provider will be reset to their default values before applying the new style provider.

variant:String

May be used to provide multiple different variations of the same UI component, each with a different appearance.

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, Event.INIT is dispatched.

The following example overrides initialization:

override private function initialize():Void {
	super.initialize();

}

Saves the calculated dimensions for the component, replacing any values that haven't been set explicitly. Returns true if the reported values have changed and Event.RESIZE was dispatched.

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

.

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.

The following example overrides updating after invalidation:

override private function update():Void {
	super.update();

}
