Styles
Styles are either common or associated with a specific theme. If the style is common, it can be used with any theme. If a style is associated with a specific theme, it can only be used if your application uses that theme.
Common Styles
| Style | Description | Defined By | ||
|---|---|---|---|---|
alignmentBaseline | Type: String CSS Inheritance: yes Specifies the baseline to which the dominant baseline aligns. For example, if you set dominantBaseline to ASCENT, setting alignmentBaseline to DESCENT aligns the top of the text with the DESCENT baseline, or below the line. The largest element in the line generally determines the baselines.
Legal values are flash.text.engine.TextBaseline.ROMAN, flash.text.engine.TextBaseline.ASCENT, flash.text.engine.TextBaseline.DESCENT, flash.text.engine.TextBaseline.IDEOGRAPHIC_TOP, flash.text.engine.TextBaseline.IDEOGRAPHIC_CENTER, flash.text.engine.TextBaseline.IDEOGRAPHIC_BOTTOM, flash.text.engine.TextBaseline.USE_DOMINANT_BASELINE, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of USE_DOMINANT_BASELINE. | ButtonBase | ||
| Type: String CSS Inheritance: no The vertical distance in pixels from the top edge of the content area to the control's baseline position. | UIComponent | ||
baselineShift | Type: Object CSS Inheritance: yes Amount to shift the baseline from the dominantBaseline value. Units are in pixels, or a percentage of fontSize (in which case, enter a string value, like 140%). Positive values shift the line up for horizontal text (right for vertical) and negative values shift it down for horizontal (left for vertical).
Legal values are flashx.textLayout.formats.BaselineShift.SUPERSCRIPT, flashx.textLayout.formats.BaselineShift.SUBSCRIPT, flashx.textLayout.formats.FormatValue.INHERIT. Legal values as a number are from -1000 to 1000. Legal values as a percent are numbers from -1000 to 1000. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of 0.0. | ButtonBase | ||
| Type: String CSS Inheritance: no The vertical distance, in pixels, from the bottom edge of the component to the bottom edge of its parent container's content area. | UIComponent | ||
cffHinting | Type: String CSS Inheritance: yes The type of CFF hinting used for this text. CFF hinting determines whether the Flash runtime forces strong horizontal stems to fit to a sub pixel grid or not. This property applies only if the renderingMode property is set to RenderingMode.CFF, and the font is embedded (fontLookup property is set to FontLookup.EMBEDDED_CFF). At small screen sizes, hinting produces a clear, legible text for human readers.
Legal values are flash.text.engine.CFFHinting.NONE, flash.text.engine.CFFHinting.HORIZONTAL_STEM, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of HORIZONTAL_STEM. | ButtonBase | ||
color | Type: uint Format: Color CSS Inheritance: yes Color of the text. A hexadecimal number that specifies three 8-bit RGB (red, green, blue) values; for example, 0xFF0000 is red and 0x00FF00 is green. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of 0. | ButtonBase | ||
digitCase | Type: String CSS Inheritance: yes The type of digit case used for this text. Setting the value to DigitCase.OLD_STYLE approximates lowercase letterforms with varying ascenders and descenders. The figures are proportionally spaced. This style is only available in selected typefaces, most commonly in a supplemental or expert font. The DigitCase.LINING setting has all-cap height and is typically monospaced to line up in charts.
Legal values are flash.text.engine.DigitCase.DEFAULT, flash.text.engine.DigitCase.LINING, flash.text.engine.DigitCase.OLD_STYLE, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of DEFAULT. | ButtonBase | ||
digitWidth | Type: String CSS Inheritance: yes Type of digit width used for this text. This can be DigitWidth.PROPORTIONAL, which looks best for individual numbers, or DigitWidth.TABULAR, which works best for numbers in tables, charts, and vertical rows.
Legal values are flash.text.engine.DigitWidth.DEFAULT, flash.text.engine.DigitWidth.PROPORTIONAL, flash.text.engine.DigitWidth.TABULAR, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of DEFAULT. | ButtonBase | ||
direction | Type: String CSS Inheritance: yes Specifies the default bidirectional embedding level of the text in the text block. Left-to-right reading order, as in Latin-style scripts, or right-to-left reading order, as in Arabic or Hebrew. This property also affects column direction when it is applied at the container level. Columns can be either left-to-right or right-to-left, just like text. Below are some examples:
Legal values are flashx.textLayout.formats.Direction.LTR, flashx.textLayout.formats.Direction.RTL, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of LTR. | ButtonBase | ||
dominantBaseline | Type: String CSS Inheritance: yes Specifies which element baseline snaps to the alignmentBaseline to determine the vertical position of the element on the line. A value of TextBaseline.AUTO selects the dominant baseline based on the locale property of the parent paragraph. For Japanese and Chinese, the selected baseline value is TextBaseline.IDEOGRAPHIC_CENTER; for all others it is TextBaseline.ROMAN. These baseline choices are determined by the choice of font and the font size.
Legal values are flashx.textLayout.formats.FormatValue.AUTO, flash.text.engine.TextBaseline.ROMAN, flash.text.engine.TextBaseline.ASCENT, flash.text.engine.TextBaseline.DESCENT, flash.text.engine.TextBaseline.IDEOGRAPHIC_TOP, flash.text.engine.TextBaseline.IDEOGRAPHIC_CENTER, flash.text.engine.TextBaseline.IDEOGRAPHIC_BOTTOM, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of flashx.textLayout.formats.FormatValue.AUTO. | ButtonBase | ||
| Type: Class Name of the skin class to use for this component when a validation error occurs. | SkinnableComponent | ||
| Type: String CSS Inheritance: no Blend mode used by the focus rectangle. | UIComponent | ||
| Type: Class CSS Inheritance: no Skin used to draw the focus rectangle. | UIComponent | ||
| Type: Number Format: Length CSS Inheritance: no Thickness, in pixels, of the focus rectangle outline. | UIComponent | ||
fontFamily | Type: String CSS Inheritance: yes The name of the font to use, or a comma-separated list of font names. The Flash runtime renders the element with the first available font in the list. For example Arial, Helvetica, _sans causes the player to search for Arial, then Helvetica if Arial is not found, then _sans if neither is found. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of Arial. | ButtonBase | ||
fontLookup | Type: String CSS Inheritance: yes Font lookup to use. Specifying FontLookup.DEVICE uses the fonts installed on the system that is running the SWF file. Device fonts result in a smaller movie size, but text is not always rendered the same across different systems and platforms. Specifying FontLookup.EMBEDDED_CFF uses font outlines embedded in the published SWF file. Embedded fonts increase the size of the SWF file (sometimes dramatically), but text is consistently displayed in the chosen font.
Legal values are flash.text.engine.FontLookup.DEVICE, flash.text.engine.FontLookup.EMBEDDED_CFF, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of DEVICE. | ButtonBase | ||
fontSize | Type: Number Format: Length CSS Inheritance: yes The size of the text in pixels. Legal values are numbers from 1 to 720 and flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of 12. | ButtonBase | ||
fontStyle | Type: String CSS Inheritance: yes Style of text. May be FontPosture.NORMAL, for use in plain text, or FontPosture.ITALIC for italic. This property applies only to device fonts (fontLookup property is set to flash.text.engine.FontLookup.DEVICE).
Legal values are flash.text.engine.FontPosture.NORMAL, flash.text.engine.FontPosture.ITALIC, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of NORMAL. | ButtonBase | ||
fontWeight | Type: String CSS Inheritance: yes Weight of text. May be FontWeight.NORMAL for use in plain text, or FontWeight.BOLD. Applies only to device fonts (fontLookup property is set to flash.text.engine.FontLookup.DEVICE).
Legal values are flash.text.engine.FontWeight.NORMAL, flash.text.engine.FontWeight.BOLD, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of NORMAL. | ButtonBase | ||
| Type: String CSS Inheritance: no The horizontal distance in pixels from the center of the component's content area to the center of the component. | UIComponent | ||
justificationRule | Type: String CSS Inheritance: yes Rule used to justify text in a paragraph. Default value is FormatValue.AUTO, which justifies text based on the paragraph's locale property. For all languages except Japanese and Chinese, FormatValue.AUTO becomes JustificationRule.SPACE, which adds extra space to the space characters. For Japanese and Chinese, FormatValue.AUTO becomes JustficationRule.EAST_ASIAN. In part, justification changes the spacing of punctuation. In Roman text the comma and Japanese periods take a full character's width but in East Asian text only half of a character's width. Also, in the East Asian text the spacing between sequential punctuation marks becomes tighter, obeying traditional East Asian typographic conventions. Note, too, in the example below the leading that is applied to the second line of the paragraphs. In the East Asian version, the last two lines push left. In the Roman version, the second and following lines push left.
Legal values are flashx.textLayout.formats.JustificationRule.EAST_ASIAN, flashx.textLayout.formats.JustificationRule.SPACE, flashx.textLayout.formats.FormatValue.AUTO, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of flashx.textLayout.formats.FormatValue.AUTO. | ButtonBase | ||
justificationStyle | Type: String CSS Inheritance: yes The style used for justification of the paragraph. Used only in conjunction with a justificationRule setting of JustificationRule.EAST_ASIAN.
Default value of FormatValue.AUTO is resolved to JustificationStyle.PUSH_IN_KINSOKU for all locales. The constants defined by the JustificationStyle class specify options for handling kinsoku characters, which are Japanese characters that cannot appear at either the beginning or end of a line. If you want looser text, specify JustificationStyle.PUSH-OUT-ONLY. If you want behavior that is like what you get with the justificationRule of JustificationRule.SPACE, use JustificationStyle.PRIORITIZE-LEAST-ADJUSTMENT.
Legal values are flash.text.engine.JustificationStyle.PRIORITIZE_LEAST_ADJUSTMENT, flash.text.engine.JustificationStyle.PUSH_IN_KINSOKU, flash.text.engine.JustificationStyle.PUSH_OUT_ONLY, flashx.textLayout.formats.FormatValue.AUTO, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of flashx.textLayout.formats.FormatValue.AUTO. | ButtonBase | ||
kerning | Type: String CSS Inheritance: yes | ButtonBase | ||
| Type: String CSS Inheritance: no The horizontal distance, in pixels, from the left edge of the component to the left edge of its parent container's content area. | UIComponent | ||
ligatureLevel | Type: String CSS Inheritance: yes Controls which of the ligatures that are defined in the font may be used in the text. The ligatures that appear for each of these settings is dependent on the font. A ligature occurs where two or more letter-forms are joined as a single glyph. Ligatures usually replace consecutive characters sharing common components, such as the letter pairs 'fi', 'fl', or 'ae'. They are used with both Latin and Non-Latin character sets. The ligatures enabled by the values of the LigatureLevel class - MINIMUM, COMMON, UNCOMMON, and EXOTIC - are additive. Each value enables a new set of ligatures, but also includes those of the previous types.Note: When working with Arabic or Syriac fonts,
Legal values are flash.text.engine.LigatureLevel.MINIMUM, flash.text.engine.LigatureLevel.COMMON, flash.text.engine.LigatureLevel.UNCOMMON, flash.text.engine.LigatureLevel.EXOTIC, flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor. If no ancestor has set this property, it will have a value of COMMON. | ButtonBase | ||
lineHeight | Type: Object CSS Inheritance: yes Leading controls for the text. The distance from the baseline of the previous or the next line (based on LeadingModel) to the baseline of the current line is equal to the maximum amount of the leading applied to any character in the line. This is either a number or a percent. If specifying a percent, enter a string value, like 140%.
Legal values as a number are from -720 to 720. Legal values as a percent are numbers from -1000% to 1000%. Legal values include flashx.textLayout.formats.FormatValue.INHERIT. Default value is undefined indicating not set. If undefined during the cascade this property will inherit its value from an ancestor.

Public Constants
Property Detail
autoRepeat | property |
autoRepeat:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
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):voidcontent | property |
content:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The content property lets you pass an arbitrary object
to be used in a custom skin of the button.
When a skin defines the optional part labelDisplay then
a string representation of content will be pushed down to
that part's text property.
The default skin uses this mechanism to render the content
as the button label.
The label property is a String typed
facade of this property. This property is bindable and it shares
the "contentChange" event with the label property.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the contentChange event.
Implementation
public function get content():Object public function set content(value:Object):voidSee also
hovered | property |
hovered:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates whether the mouse pointer is over the button. Used to determine the skin state.
Implementation
protected function get hovered():Boolean protected function set hovered(value:Boolean):voidkeyboardPressed | property |
keyboardPressed:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates whether a keyboard key is pressed while the button is in focus. Used to determine the skin state.

Text to appear on the ButtonBase control.
If the label is wider than the ButtonBase 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 control.
If you have also set a tooltip by using the tooltip
property, the tooltip is displayed rather than the label text.
This is the default ButtonBase property.
This property is a String typed facade to the
content property. This property is bindable and it shares
dispatching the "contentChange" event with the content
property.
The default value is "".
This property can be used as the source for data binding. When this property is modified, it dispatches the contentChange event.

Method Detail
buttonReleased | () | method |
protected function buttonReleased():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
This method is called when handling a MouseEvent.MOUSE_UP event
when the user clicks on the button. It is only called when the button
is the target and when mouseCaptured is true.
It allows subclasses to update the properties of the button right as it is clicked to
avoid the button being in transitional states between the mouse up
and click events.
clickHandler | () | method |
protected function clickHandler(event:MouseEvent):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Override this method in subclasses to handle the click event rather than
adding a separate handler.
This method is not called if the button is disabled.
Parameters
event:MouseEvent — The Event object associated with the event.
|
mouseEventHandler | () | method |
protected function mouseEventHandler(event:Event):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
This method handles the mouse events, calls the clickHandler method
where appropriate and updates the hovered and
mouseCaptured properties.
This method gets called to handle MouseEvent.ROLL_OVER,
MouseEvent.ROLL_OUT, MouseEvent.MOUSE_DOWN,
MouseEvent.MOUSE_UP, and MouseEvent.CLICK events.
Parameters
event:Event — The Event object associated with the event.

mx.events.FlexEvent.BUTTON_DOWN| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Dispatched when the user presses the ButtonBase control.
If the autoRepeat property is true,
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 |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
