In the following example, a set of radios are created, along with a
ToggleGroup to group them together:
var group = new ToggleGroup();
group.addEventListener(Event.CHANGE, group_changeHandler);
var radio1 = new Radio();
radio1.text = "One";
radio1.toggleGroup = group;
this.addChild(radio1);
var radio2 = new Radio();
radio2.text = "Two";
radio2.toggleGroup = group;
this.addChild(radio2);
var radio3 = new Radio();
radio3.text = "Three";
radio3.toggleGroup = group;

@:style@:flash.propertydisabledIcon:DisplayObject
The icon to display when the button is disabled, and no higher
priority icon was passed to setIconForState() for the button's current
state.
In the following example, the button's disabled icon is changed:
button.enabled = false;
button.disabledIcon = new Bitmap(bitmapData);The next example sets a disabled icon, but also provides an icon for
the ToggleButtonState.DISABLED(true) state that will be used instead
of the disabled icon:
button.disabledIcon = new Bitmap(bitmapData);
button.setIconForState(ToggleButtonState.DISABLED(true), new Bitmap(bitmapData2));Note: If the current state is ToggleButtonState.DISABLED(true), and
both the disabledIcon and selectedIcon are set, the disabledIcon
takes precedence over the selectedIcon.

@:style@:flash.propertydisabledTextFormat:AbstractTextFormat
The font styles used to render the button's text when the button is disabled.
In the following example, the button's disabled text formatting is customized:
button.enabled = false;
button.disabledTextFormat = new TextFormat("Helvetica", 20, 0xee0000);The next example sets a disabled text format, but also provides a text
format for the ToggleButtonState.DISABLED(true) state that will be
used instead of the disabled text format:
button.disabledTextFormat = new TextFormat("Helvetica", 20, 0xee0000);
button.setTextFormatForState(ToggleButtonState.DISABLED(true), new TextFormat("Helvetica", 20, 0xff0000));Note: If the current state is ToggleButtonState.DISABLED(true), and
both the disabledTextFormat and selectedTextFormat are set, the
disabledTextFormat takes precedence over the selectedTextFormat.

@:style@:flash.propertyembedFonts:Bool
Determines if an embedded font is used or not.
In the following example, the button uses embedded fonts:
button.embedFonts = true;1.0.0
.See also:
@:style@:flash.propertygap:Float
The space, measured in pixels, between the button's icon and its text.
Applies to either horizontal or vertical spacing, depending on the value
of iconPosition.
If the gap is set to Math.POSITIVE_INFINITY, the icon and the text
will be positioned as far apart as possible. In other words, they will
be positioned at the edges of the button (adjusted for padding).
The following example creates a gap of 20 pixels between the icon and the text:
button.text = "Click Me";
button.icon = new Bitmap(bitmapData);
button.gap = 20.0;1.0.0
.See also:
@:style@:flash.propertyhorizontalAlign:HorizontalAlign
How the content is positioned horizontally (along the x-axis) within the button.
The following example aligns the button's content to the left:
button.verticalAlign = LEFT;Note: The HorizontalAlign.JUSTIFY constant is not supported by this
component.
See also:
htmlText:String
Text displayed by the button that is parsed as a simple form of HTML.
The following example sets the button's HTML text:
button.htmlText = "<b>Hello</b> <i>World</i>";1.0.0
.See also:
@:style@:flash.propertyicon:DisplayObject
The display object to use as the button's icon.
To render a different icon depending on the button's current state,
pass additional icons to setIconForState().
The following example gives the button an icon:
button.icon = new Bitmap(bitmapData);To change the position of the icon relative to the button's text, see
iconPosition and gap.
button.icon = new Bitmap(bitmapData);
button.iconPosition = RIGHT;
button.gap = 20.0;1.0.0
.See also:
@:style@:flash.propertyiconOffsetX:Float
Offsets the x position of the icon by a certain number of pixels. This does not affect the measurement of the button. The button's width will not get smaller or larger when the icon is offset from its default x position.
The following example offsets the x position of the button's icon by 20 pixels:
button.iconOffsetX = 20.0;1.0.0
.See also:
@:style@:flash.propertyiconOffsetY:Float
Offsets the y position of the icon by a certain number of pixels. This does not affect the measurement of the button. The button's height will not get smaller or larger when the icon is offset from its default y position.
The following example offsets the y position of the button's icon by 20 pixels:
button.iconOffsetY = 20.0;1.0.0
.See also:
@:style@:flash.propertyiconPosition:RelativePosition
The location of the button's icon, relative to its text.
The following example positions the icon to the right of the text:
button.text = "Click Me";
button.icon = new Bitmap(texture);
button.iconPosition = RIGHT;1.0.0
.See also:
@:style@:flash.propertyminGap:Float
If the value of the gap property is Math.POSITIVE_INFINITY, meaning
that the gap will fill as much space as possible and position the icon
and text on the edges of the button, the final calculated value of the
gap will not be smaller than the value of the minGap property.
The following example ensures that the gap is never smaller than 20 pixels:
button.gap = Math.POSITIVE_INFINITY;
button.minGap = 20.0;1.0.0
.See also:
@:style@:flash.propertypaddingBottom:Float
The minimum space, in pixels, between the button's bottom edge and the button's content.
In the following example, the button's bottom padding is set to 20 pixels:
button.paddingBottom = 20.0;1.0.0
.@:style@:flash.propertypaddingLeft:Float
The minimum space, in pixels, between the button's left edge and the button's content.
In the following example, the button's left padding is set to 20 pixels:
button.paddingLeft = 20.0;1.0.0
.@:style@:flash.propertypaddingRight:Float
The minimum space, in pixels, between the button's right edge and the button's content.

the ToggleButtonState.DOWN(true) state that will be used instead of
the selected icon:
button.selectedIcon = new Bitmap(bitmapData);
button.setIconForState(ToggleButtonState.DOWN(true), new Bitmap(bitmapData2));Note: If the current state is ToggleButtonState.DISABLED(true), and

button.backgroundSkin = new Bitmap(bitmapData);1.0.0
.See also:
read onlycurrentState:ToggleButtonState
The current state of the toggle button.
When the value of the currentState property changes, the button will
dispatch an event of type FeathersEvent.STATE_CHANGE.
1.0.0
.See also:
@:style@:flash.propertykeepDownStateOnRollOut:Bool
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;1.0.0
.selected:Bool
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.
When the value of the selected property changes, the button will
dispatch an event of type Event.CHANGE.
The following example selects the button:
button.selected = true;The following example listens for changes to the selected property:
button.addEventListener(Event.CHANGE, (event:Event) -> {
trace("selected changed: " + button.selected)
});Warning: Do not listen for TriggerEvent.TRIGGER to be notified
when the selected property changes. You must listen for
Event.CHANGE, which is dispatched after TriggerEvent.TRIGGER.

@:style@:flash.propertyselectedBackgroundSkin:DisplayObject
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);1.0.0
.See also:
toggleable:Bool
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;1.0.0

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.
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.

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()); // true1.0.0
.runWithoutInvalidation(callback:() ‑> Void):Void
Calls a function that temporarily disables invalidation. In other words,
calls to setInvalid() will be ignored until the function returns.
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()); // true1.0.0
.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.

.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.
