Starting with Flex 4.0, Adobe recommends that you use the spark.components.Button class as an alternative to this class.

The Button control is a commonly used rectangular button. Button controls look like they can be pressed. They can have a text label, an icon, or both on their face.

Buttons typically use event listeners to perform an action when the user selects the control. When a user clicks the mouse on a Button control, and the Button control is enabled, it dispatches a click event and a buttonDown event. A button always dispatches events such as the mouseMove, mouseOver, mouseOut, rollOver, rollOut, mouseDown, and mouseUp events whether enabled or disabled.

You can customize the look of a Button control and change its functionality from a push button to a toggle button. You can change the button appearance by using a skin for each of the button's states.

The label of a Button control uses a bold typeface. If you embed a font that you want to use for the label of the Button control, you must embed the bold typeface; for example:

  <fx:style>
    @font-face {
      src:url("../MyFont-Bold.ttf");        
      fontFamily: myFont;
      fontWeight: bold;
    }
   .myBoldStyle {
      fontFamily: myFont;
      fontWeight: bold;
    } 
  </fx:style>
  ...
  <mx:Button ... styleName="myBoldStyle"/>
  

The Button control has the following default characteristics:

CharacteristicDescription
Default sizeA size large enough to hold the label text, and any icon
Minimum size0 pixels
Maximum sizeNo limit

Property Detail

autoRepeat

property
autoRepeat:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Specifies whether to dispatch repeated buttonDown events if the user holds down the mouse button.

The default value is false.



Implementation
    public function get autoRepeat():Boolean
    public function set autoRepeat(value:Boolean):void

data

property 
data:Object

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The data property lets you pass a value to the component when you use it as an item renderer or item editor. You typically use data binding to bind a field of the data property to a property of this component.

When you use the control as a drop-in item renderer or drop-in item editor, Flex automatically writes the current value of the item to the selected property of this control.

You do not set this property in MXML.

The default value is null.

This property can be used as the source for data binding. When this property is modified, it dispatches the dataChange event.



Implementation
    public function get data():Object
    public function set data(value:Object):void

emphasized

property 
emphasized:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Draws a thick border around the Button control when the control is in its up state if emphasized is set to true.

The default value is false.



Implementation
    public function get emphasized():Boolean
    public function set emphasized(value:Boolean):void

fontContext

property 
fontContext:IFlexModuleFactory

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The module factory that provides the font context for this component.



Implementation
    public function get fontContext():IFlexModuleFactory
    public function set fontContext(value:IFlexModuleFactory):void

icons

property 
protected var icons:Array

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The icons array contains references to all icons that have been created. Since each icon is a child Sprite of this button, we need this array to keep track of which children are icons. Each icon has a name property indicating which icon it is; for example, the instance of the class specified by the falseUpIcon style has the name "falseUpIcon" and can be found using getChildByName(). Note that there is no falseUpIcon property of Button containing a reference to this icon instance. New icons are created and added to this array in viewIcon().

label

property 
label:String

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Text to appear on the Button control.

If the label is wider than the Button control, the label is truncated and terminated by an ellipsis (...). The full label displays as a tooltip when the user moves the mouse over the Button control. If you have also set a tooltip by using the tooltip property, the tooltip is displayed rather than the label text.

The default value is "".

This property can be used as the source for data binding. When this property is modified, it dispatches the labelChanged event.



Implementation
    public function get label():String
    public function set label(value:String):void

labelPlacement

property 
labelPlacement:String

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Orientation of the label in relation to a specified icon. Valid MXML values are right, left, bottom, and top.

In ActionScript, you can use the following constants to set this property: ButtonLabelPlacement.RIGHT, ButtonLabelPlacement.LEFT, ButtonLabelPlacement.BOTTOM, and ButtonLabelPlacement.TOP.

The default value is ButtonLabelPlacement.RIGHT.

This property can be used as the source for data binding. When this property is modified, it dispatches the labelPlacementChanged event.



Implementation
    public function get labelPlacement():String
    public function set labelPlacement(value:String):void

listData

property 
listData:BaseListData

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

When a component is used as a drop-in item renderer or drop-in item editor, Flex initializes the listData property of the component with the appropriate data from the list control. The component can then use the listData property to initialize the data property of the drop-in item renderer or drop-in item editor.

You do not set this property in MXML or ActionScript; Flex sets it when the component is used as a drop-in item renderer or drop-in item editor.

The default value is null.

This property can be used as the source for data binding. When this property is modified, it dispatches the dataChange event.



Implementation
    public function get listData():BaseListData
    public function set listData(value:BaseListData):void

selected

property 
selected:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Indicates whether a toggle button is toggled on (true) or off (false). This property can be set only if the toggle property is set to true.

For a CheckBox control, indicates whether the box is displaying a check mark. For a RadioButton control, indicates whether the control is selected.

The user can change this property by clicking the control, but you can also set the property programmatically.

In previous versions, If the toggle property was set to true, changing this property also dispatched a change event. Starting in version 3.0, setting this property programmatically only dispatches a valueCommit event.

The default value is false.

This property can be used as the source for data binding. When this property is modified, it dispatches the valueCommit event.



Implementation
    public function get selected():Boolean
    public function set selected(value:Boolean):void

selectedField

property 
public var selectedField:String = "null"

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The name of the field in the data property which specifies the value of the Button control's selected property. You can set this property when you use the Button control in an item renderer. The default value is null, which means that the Button control does not set its selected state based on a property in the data property.

The default value is null.

stickyHighlighting

property 
public var stickyHighlighting:Boolean = false

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

If false, the Button displays its down skin when the user presses it but changes to its over skin when the user drags the mouse off of it. If true, the Button displays its down skin when the user presses it, and continues to display this skin when the user drags the mouse off of it.

Button subclasses, such as the SliderThumb and ScrollThumb classes or the up and down arrows of a ScrollBar, set this property to true.

The default value is false.

textField

property 
protected var textField:mx.core:IUITextField

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The internal UITextField object that renders the label of this Button.

The default value is null.

toggle

property 
toggle:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Controls whether a Button is in a toggle state or not. If true, clicking the button toggles it between a selected and an unselected state. You can get or set this state programmatically by using the selected property. If false, the button does not stay pressed after the user releases it. In this case, its selected property is always false. Buttons like this are used for performing actions. When toggle is set to false, selected is forced to false because only toggle buttons can be selected.

The default value is false.

This property can be used as the source for data binding. When this property is modified, it dispatches the toggleChanged event.



Implementation
    public function get toggle():Boolean
    public function set toggle(value:Boolean):void
