The Spark Group, DataGroup, and RichEditableText components implement the IViewport interface and can be used as the children of the Scroller control, as the following example shows:
<s:Scroller width="100" height="100">
<s:Group>
<mx:Image width="300" height="400"
source="@Embed(source='assets/logo.jpg')"/>
</s:Group>
</s:Scroller>
The size of the Image control is set larger than that of its parent Group container. By default, the child extends past the boundaries of the parent container. Rather than allow the child to extend past the boundaries of the parent container, the Scroller specifies to clip the child to the boundaries and display scroll bars.
Not all Spark containers implement the IViewPort interface. Therefore, those containers, such as the Border and SkinnableContainer containers, cannot be used as the direct child of the Scroller component. However, all Spark containers can have a Scroller component as a child component. For example, to use scroll bars on a child of the Spark Border container, wrap the child in a Scroller component.
To make the entire Border container scrollable, wrap it in a Group container. Then, make the Group container the child of the Scroller component, For skinnable Spark containers that do not implement the IViewport interface, you can also create a custom skin for the container that includes the Scroller component.
The IViewport interface defines a viewport for the components that implement it.
A viewport is a rectangular subset of the area of a container that you want to display,
rather than displaying the entire container.
The scroll bars control the viewport's horizontalScrollPosition and
verticalScrollPosition properties.
scroll bars make it possible to view the area defined by the viewport's
contentWidth and contentHeight properties.
You can combine scroll bars with explicit settings for the container's viewport. The viewport settings determine the initial position of the viewport, and then you can use the scroll bars to move it, as the following example shows:
<s:Scroller width="100" height="100">
<s:Group
horizontalScrollPosition="50" verticalScrollPosition="50">
<mx:Image width="300" height="400"
source="@Embed(source='assets/logo.jpg')"/>
</s:Group>
</s:Scroller>
The scroll bars are displayed according to the vertical and horizontal scroll bar
policy, which can be auto, on, or off.
The auto policy means that the scroll bar will be visible and included
in the layout when the viewport's content is larger than the viewport itself.
The Scroller skin layout cannot be changed. It is unconditionally set to a
private layout implementation that handles the scroll policies. Scroller skins
can only provide replacement scroll bars. To gain more control over the layout
of a viewport and its scroll bars, instead of using Scroller, just add them
to a Group and use the scroll bar viewport property
to link them together.
The Scroller control has the following default characteristics:
| Characteristic | Description |
|---|---|
| Default size | 0 |
| Minimum size | 0 |
| Maximum size | 10000 pixels wide and 10000 pixels high |
| Default skin class | spark.skins.spark.ScrollerSkin |

| 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.

breakOpportunity | Type: String CSS Inheritance: yes Controls where lines are allowed to break when breaking wrapping text into multiple lines. Set to BreakOpportunity.AUTO to break text normally. Set to BreakOpportunity.NONE to not break the text unless the text would overrun the measure and there are no other places to break the line. Set to BreakOpportunity.ANY to allow the line to break anywhere, rather than just between words. Set to BreakOpportunity.ALL to have each typographic cluster put on a separate line (useful for text on a path).
Legal values are flash.text.engine.BreakOpportunity.ALL, flash.text.engine.BreakOpportunity.ANY, flash.text.engine.BreakOpportunity.AUTO, flash.text.engine.BreakOpportunity.NONE, 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 AUTO. | Scroller | ||
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.

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. | Scroller | ||
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.

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.

| Type: Class Name of the skin class to use for this component when a validation error occurs. | SkinnableComponent | ||
firstBaselineOffset | Type: Object CSS Inheritance: yes Specifies the baseline position of the first line in the container. Which baseline this property refers to depends on the container-level locale. For Japanese and Chinese, it is TextBaseline.IDEOGRAPHIC_BOTTOM; for all others it is TextBaseline.ROMAN.
The offset from the top inset (or right inset if blockProgression is RL) of the container to the baseline of the first line can be either BaselineOffset.ASCENT, meaning equal to the ascent of the line, BaselineOffset.LINE_HEIGHT, meaning equal to the height of that first line, or any fixed-value number to specify an absolute distance. BaselineOffset.AUTO aligns the ascent of the line with the container top inset.
Legal values as a string are flashx.textLayout.formats.BaselineOffset.AUTO, flashx.textLayout.formats.BaselineOffset.ASCENT, flashx.textLayout.formats.BaselineOffset.LINE_HEIGHT, flashx.textLayout.formats.FormatValue.INHERIT and numbers from 0 to 1000.

| 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. | Scroller | ||
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. | Scroller | ||
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. | Scroller | ||

inactiveTextSelectionColor | Type: uint Format: Color CSS Inheritance: yes The color of text when the component is disabled. | Scroller | ||
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. | Scroller | ||
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. | Scroller | ||

| Type: String CSS Inheritance: yes Specifies the desired layout direction of a component. | UIComponent | ||
leadingModel | Type: String CSS Inheritance: yes Specifies the leading model, which is a combination of leading basis and leading direction. Leading basis is the baseline to which the lineHeight property refers. Leading direction determines whether the lineHeight property refers to the distance of a line's baseline from that of the line before it or the line after it. The default value of FormatValue.AUTO is resolved based on the paragraph's locale property. For Japanese and Chinese, it is LeadingModel.IDEOGRAPHIC_TOP_DOWN and for all others it is LeadingModel.ROMAN_UP.Leading Basis:
Leading Direction:
Legal values are flashx.textLayout.formats.LeadingModel.ROMAN_UP, flashx.textLayout.formats.LeadingModel.IDEOGRAPHIC_TOP_UP, flashx.textLayout.formats.LeadingModel.IDEOGRAPHIC_CENTER_UP, flashx.textLayout.formats.LeadingModel.IDEOGRAPHIC_TOP_DOWN, flashx.textLayout.formats.LeadingModel.IDEOGRAPHIC_CENTER_DOWN, flashx.textLayout.formats.LeadingModel.APPROXIMATE_TEXT_FIELD, flashx.textLayout.formats.LeadingModel.ASCENT_DESCENT_UP, flashx.textLayout.formats.LeadingModel.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 AUTO. | Scroller | ||
| 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. | Scroller | ||
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. If no ancestor has set this property, it will have a value of 120%. | Scroller | ||
lineThrough | Type: Boolean CSS Inheritance: yes If true, applies strikethrough, a line drawn through the middle of the text.
Legal values are true, false 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 false. | Scroller | ||

Setters can take an array of flashx.textLayout.formats.TabStopFormat, a condensed string representation, undefined, or FormatValue.INHERIT. The condensed string representation is always converted into an array of flashx.textLayout.formats.TabStopFormat. The string-based format is a list of tab stops, where each tab stop is delimited by one or more spaces. A tab stop takes the following form: <alignment type><alignment position>|<alignment token>. The alignment type is a single character, and can be S, E, C, or D (or lower-case equivalents). S or s for start, E or e for end, C or c for center, D or d for decimal. The alignment type is optional, and if its not specified will default to S. The alignment position is a Number, and is specified according to FXG spec for Numbers (decimal or scientific notation). The alignment position is required. The vertical bar is used to separate the alignment position from the alignment token, and should only be present if the alignment token is present.

measuredSizeIncludesScrollBars | property |
measuredSizeIncludesScrollBars:Boolean
If true, the Scroller's measured size includes the space required for
the visible scroll bars, otherwise the Scroller's measured size depends
only on its viewport.
Components like TextArea, which "reflow" their contents to fit the
available width or height may use this property to stabilize their
measured size. By default a TextArea's is defined by its widthInChars
and heightInChars properties and in many applications it's preferable
for the measured size to remain constant, event when scroll bars are displayed
by the TextArea skin's Scroller.
In components where the content does not reflow, like a typical List's items, the default behavior is preferable because it makes it less likely that the component's content will be obscured by a scroll bar.
The default value is true.
Implementation
public function get measuredSizeIncludesScrollBars():Boolean public function set measuredSizeIncludesScrollBars(value:Boolean):voidminViewportInset | property |
minViewportInset:Number
The minimum space between the viewport and the edges of the Scroller.
If neither of the scroll bars is visible, then the viewport is inset by
minViewportInset on all four sides.
If a scroll bar is visible then the viewport is inset by minViewportInset
or by the scroll bar's size, whichever is larger.
ScrollBars are laid out flush with the edges of the Scroller.
The default value is 0.
Implementation
public function get minViewportInset():Number public function set minViewportInset(value:Number):voidnumElements | property |
numElements:int [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns 1 if there is a viewport, 0 otherwise.
Implementation
public function get numElements():intviewport | property |
viewport:IViewport| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The viewport component to be scrolled.
The viewport is added to the Scroller component's skin,
which lays out both the viewport and scroll bars.
When the viewport property is set, the viewport's
clipAndEnableScrolling property is
set to true to enable scrolling.
The Scroller does not support rotating the viewport directly. The viewport's
contents can be transformed arbitrarily, but the viewport itself cannot.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.
