A simple toggle button control with selection, pointer states, but no content, that is useful for purposes like skinning. For a more full-featured toggle button, with a label and icon, see feathers.controls.ToggleButton instead.

Variables

@:value(null)@:stylebackgroundSkin:DisplayObject = null

The default background skin for the toggle button, which is used when no other skin is defined for the current state with setSkinForState().

The following example passes a bitmap for the button to use as a background skin:

button.backgroundSkin = new Bitmap(bitmapData);

See:

@:value(UP(false))read onlycurrentState:ToggleButtonState = UP(false)

The current state of the toggle button.

.

See:

@:value(false)@:stylekeepDownStateOnRollOut:Bool = false

Determines if a pressed button should remain in the down state if the pointer moves outside of the button's bounds. Useful for controls like HSlider, VSlider, or ToggleSwitch to keep a thumb in the down state while it is being dragged around by the pointer.

The following example ensures that the button's down state remains active on roll out.

button.keepDownStateOnRollOut = true;

.

@:value(false)@:isVarselected:Bool = false

Indicates if the button is selected or not. The button may be selected programmatically, even if toggleable is false, but generally, toggleable should be set to true to allow the user to select and deselect it by triggering the button with a click or tap. If focus management is enabled, and the button has focus, a button may also be triggered with the spacebar.

The following example selects the button:

button.selected = true;

Warning: Do not listen for FeathersEvent.TRIGGERED to be notified when the selected property changes. You must listen for Event.CHANGE, which is dispatched after FeathersEvent.TRIGGERED.

See:

@:value(null)@:styleselectedBackgroundSkin:DisplayObject = null

The default background skin for the toggle button when the selected property is true. Takes precendence over backgroundSkin, but will defer to another skin that is defined for the current state with setSkinForState().

The following example gives the toggle button a default selected skin:

button.selectedBackgroundSkin = new Bitmap(bitmapData);

.

See:

@:value(true)toggleable:Bool = true

Determines if the button may be selected or deselected as a result of user interaction. If true, the value of the selected property will be toggled when the button is triggered.

The following example disables the ability to toggle on click or tap:

button.toggleable = false;

Methods

getSkinForState (state:ToggleButtonState):DisplayObject

Gets the skin to be used by the toggle button when its currentState property matches the specified state value.

If a skin is not defined for a specific state, returns null.

Available since

1.0.0

.

See:

@stylesetSkinForState (state:ToggleButtonState, skin:DisplayObject):Void

Set the skin to be used by the toggle button when its currentState property matches the specified state value.

If a skin is not defined for a specific state, the value of the backgroundSkin property will be used instead.

Inherited Variables

Defined by FeathersControl

@:value(false)read onlycreated:Bool = false

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);
}

See:

@:value(true)@:isVarenabled:Bool = true

@:value(false)read onlyinitialized:Bool = false

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:

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.

.

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.

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, Event.INIT is dispatched.

The following example overrides initialization:

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

}

private@:dox(show)setStyle (styleName:String, ?state:EnumValue):Bool

Determines if a style may be changed, and restricts the style from being changed in the future, if necessary.

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

@:value({ flag : null })isInvalid (?flag:String):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

.

@:value({ flag : null })setInvalid (?flag:String):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

private@:dox(show)setInvalidationFlag (flag:String):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

.

See:

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();

}
