 | Starting with Flex 4.0, Apache recommends that you use the spark.components.Button class as an alternative to this class. |
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:
| Characteristic | Description |
|---|---|
| Default size | A size large enough to hold the label text, and any icon |
| Minimum size | 0 pixels |
| Maximum size | No limit |
Hide MXML SyntaxThe <mx:Button> tag inherits all the tag attributes
of its superclass, and adds the following tag attributes:

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.

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

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

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.

this event is dispatched repeatedly as long as the button stays down.
FlexEvent.BUTTON_DOWN constant defines the value of the
type property of the event object for a buttonDown event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
