text property inherited from TextBase.
The formatting of the text is specified by the element's CSS styles,
such as fontFamily and fontSize.
Label uses of the Flash Text Engine (FTE) in Flash Player to provide high-quality international typography. Because Label is fast and lightweight, it is especially suitable for use cases that involve rendering many small pieces of non-interactive text, such as item renderers and labels in Button skins.
The Spark architecture provides three text "primitives" -- Label, RichText, and RichEditableText -- as part of its pay-only-for-what-you-need philosophy. Label is the fastest and most lightweight, but is limited in its capabilities: no complex formatting, no scrolling, no selection, no editing, and no hyperlinks. RichText and RichEditableText are built on the Text Layout Framework (TLF) library, rather than on FTE. RichText adds the ability to render rich HTML-like text with complex formatting, but is still completely non-interactive. RichEditableText is the slowest and heaviest, but can do it all: it supports scrolling with virtualized TextLines, selection, editing, hyperlinks, and images loaded from URLs. You should use the fastest one that meets your needs.
The Spark Label control is similar to the MX Label control, mx.controls.Label. The most important differences are:
- Spark Label uses FTE, the player's new text engine, while MX Label uses the TextField class.
- Spark Label offers better typography, and better support for international languages, than MX Label.
- Spark Label can display multiple lines, which MX Label cannot.
- MX Label can display a limited subset of HTML, while Spark Label can only display text with uniform formatting.
- MX Label can be made selectable, while Spark Label cannot.
In Spark Label, three character sequences are recognized
as explicit line breaks: CR ("\r"), LF ("\n"),
and CR+LF ("\r\n").
If you don't specify any kind of width for a Label, then the longest line, as determined by these explicit line breaks, determines the width of the Label.
If you do specify some kind of width, then the specified text is
word-wrapped at the right edge of the component's bounds, because the
default value of the lineBreak style is "toFit".
If the text extends below the bottom of the component,
it is clipped.
To disable this automatic wrapping, set the lineBreak
style to "explicit". Then lines are broken only where
the text contains an explicit line break,
and the ends of lines extending past the right edge is clipped.
If you have more text than you have room to display it,
Label can truncate the text for you.
Truncating text means replacing excess text
with a truncation indicator such as "...".
See the inherited properties maxDisplayedLines
and isTruncated.
You can control the line spacing with the lineHeight style.
You can horizontally and vertically align the text within the element's
bounds using the textAlign, textAlignLast,
and verticalAlign styles.
You can inset the text from the element's edges using the
paddingLeft, paddingTop,
paddingRight, and paddingBottom styles.
By default a Label has no background,
but you can draw one using the backgroundColor
and backgroundAlpha styles.
Borders are not supported.
If you need a border, or a more complicated background, use a separate
graphic element, such as a Rect, behind the Label.
Label supports displaying left-to-right (LTR) text such as French,
right-to-left (RTL) text such as Arabic, and bidirectional text
such as a French phrase inside of an Arabic paragraph.
If the predominant text direction is right-to-left,
set the direction style to "rtl".
The textAlign style defaults to "start",
which makes the text left-aligned when direction
is "ltr" and right-aligned when direction
is "rtl".
To get the opposite alignment,
set textAlign to "end".
Label uses the TextBlock class in the Flash Text Engine to create one or more TextLine objects to statically display its text String in the format determined by its CSS styles. For performance, its TextLines do not contain information about individual glyphs; for more info, see flash.text.engine.TextLineValidity.STATIC.
The Label control has the following default characteristics:
| Characteristic | Description |
|---|---|
| Default size | 0 pixels wide by 12 pixels high if it contains no text, and large enough ti display the text if it does |
| Minimum size | 0 pixels |
| Maximum size | 10000 pixels wide and 10000 pixels high |

| 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. | Label | ||
| Type: Number CSS Inheritance: no The alpha level of the color defined by the backgroundColor style. | TextBase | ||
| Type: uint Format: Color CSS Inheritance: no The color of the background of the entire bounding rectangle of this component. | TextBase | ||
| 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. | Label | ||
| 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. | Label | ||
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. | Label | ||
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. | Label | ||
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. | Label | ||
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. | Label | ||
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. | Label | ||
| Type: uint Format: Color CSS Inheritance: yes Color of the component highlight when validation fails. | UIComponent | ||
| 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. | Label | ||
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. | Label | ||
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. | Label | ||
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. | Label | ||
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. | Label | ||
| 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. | Label | ||
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. | Label | ||
