Spark Theme Styles
| Style | Description | Defined By | ||
|---|---|---|---|---|
accentColor | Type: uint Format: Color CSS Inheritance: yes Theme: spark Accent color used by component skins. The default button skin uses this color to tint the background. Slider track highlighting uses this color. The default value is #0099FF. | ScrollControlBase | ||
borderAlpha | Type: Number CSS Inheritance: no Theme: spark Alpha of the border. The default value is 1. | ScrollControlBase | ||
borderColor | Type: uint Format: Color CSS Inheritance: no Theme: halo, spark Color of the border. The default value depends on the component class; if not overridden for the class, the default value is 0xB7BABC
for the Halo theme and 0x696969 for the Spark theme.
| ScrollControlBase | ||
borderVisible | Type: Boolean CSS Inheritance: no Theme: spark Visibility of the border. The default value is true. | ScrollControlBase | ||
chromeColor | Type: uint Format: Color CSS Inheritance: yes Theme: spark The main color for a component. | ScrollControlBase | ||
contentBackgroundAlpha | Type: Number CSS Inheritance: yes Theme: spark The alpha of the content background for this component. | ScrollControlBase | ||

dropShadowVisible | Type: Boolean CSS Inheritance: no Theme: spark Boolean property that specifies whether the component has a visible drop shadow. The default value is false.
Note: For drop shadows to appear on containers, set
| ScrollControlBase | ||
focusColor | Type: uint Format: Color CSS Inheritance: yes Theme: spark Color of focus ring when the component is in focus The default value is 0x70B2EE. | ScrollControlBase | ||
symbolColor | Type: uint Format: Color CSS Inheritance: yes Theme: spark Color of any symbol of a component. Examples include the check mark of a CheckBox or the arrow of a ScrollBar button. The default value is 0x000000. | ScrollControlBase | ||
Halo Theme Styles
| Style | Description | Defined By | ||
|---|---|---|---|---|
backgroundAlpha | Type: Number CSS Inheritance: no Theme: halo Alpha level of the color defined by the backgroundColor
property, of the image or SWF file defined by the backgroundImage
style.
Valid values range from 0.0 to 1.0. For most controls, the default value is 1.0,
but for ToolTip controls, the default value is 0.95 and for Alert controls, the default value is 0.9.
The default value is 1.0. | ScrollControlBase | ||
backgroundColor | Type: uint Format: Color CSS Inheritance: no Theme: halo Background color of a component. You can have both a backgroundColor and a
backgroundImage set.
Some components do not have a background.
The DataGrid control ignores this style.
The default value is undefined, which means it is not set.
If both this style and the backgroundImage style
are undefined, the component has a transparent background.
For the Application container, this style specifies the background color while the application loads, and a background gradient while it is running. Flex calculates the gradient pattern between a color slightly darker than the specified color, and a color slightly lighter than the specified color. The default skins of most Flex controls are partially transparent. As a result, the background color of
a container partially "bleeds through" to controls that are in that container. You can avoid this by setting the
alpha values of the control's
<mx:Container backgroundColor="0x66CC66"/>
<mx:ControlName ... fillAlphas="[1,1]"/>
</mx:Container>
| ScrollControlBase | ||
backgroundDisabledColor | Type: uint Format: Color CSS Inheritance: yes Theme: halo Background color of the component when it is disabled. The global default value is undefined.
The default value for List controls is 0xDDDDDD (light gray).
If a container is disabled, the background is dimmed, and the degree of
dimming is controlled by the disabledOverlayAlpha style.
| ScrollControlBase | ||
backgroundImage | Type: Object Format: File CSS Inheritance: no Theme: halo Background image of a component. This can be an absolute or relative URL or class. You can set either the backgroundColor or the
backgroundImage. The background image is displayed
on top of the background color.
The default value is undefined, meaning "not set".
If this style and the backgroundColor style are undefined,
the component has a transparent background.
The default skins of most Flex controls are partially transparent. As a result, the background image of
a container partially "bleeds through" to controls that are in that container. You can avoid this by setting the
alpha values of the control's
<mx:Container backgroundColor="0x66CC66"/>
<mx:ControlName ... fillAlphas="[1,1]"/>
</mx:Container>
| ScrollControlBase | ||
backgroundSize | Type: String CSS Inheritance: no Theme: halo Scales the image specified by backgroundImage
to different percentage sizes.
A value of "100%" stretches the image
to fit the entire component.
To specify a percentage value, you must include the percent sign (%).
The default for the Application container is 100%.
The default value for all other containers is auto, which maintains
the original size of the image.
| ScrollControlBase | ||
borderColor | Type: uint Format: Color CSS Inheritance: no Theme: halo, spark Color of the border. The default value depends on the component class; if not overridden for the class, the default value is 0xB7BABC
for the Halo theme and 0x696969 for the Spark theme.
| ScrollControlBase | ||
borderSides | Type: String CSS Inheritance: no Theme: halo Bounding box sides. A space-delimited String that specifies the sides of the border to show. The String can contain "left", "top",

The default value is false.
Note: For drop shadows to appear on containers, set
| ScrollControlBase | ||
shadowDirection | Type: String CSS Inheritance: no Theme: halo Direction of the drop shadow. Possible values are "left", "center",
and "right".
The default value is "center". | ScrollControlBase | ||
shadowDistance | Type: Number Format: Length CSS Inheritance: no Theme: halo Distance of the drop shadow. If the property is set to a negative value, the shadow appears above the component. The default value is 2. | ScrollControlBase | ||

Public Constants
Property Detail
border | property |
protected var border:IFlexDisplayObject| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The border object.
borderMetrics | property |
borderMetrics:EdgeMetrics [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Returns an EdgeMetrics object that has four properties:
left, top, right,
and bottom.
The value of each property is equal to the thickness of one side
of the border, expressed in pixels.
Implementation
public function get borderMetrics():EdgeMetricshorizontalScrollBar | property |
protected var horizontalScrollBar:ScrollBar| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The horizontal scroll bar.
This property is null if no horizontal scroll bar
is currently displayed.
In general you do not access this property directly.
Manipulation of the horizontalScrollPolicy
and horizontalScrollPosition
properties should provide sufficient control over the scroll bar.
horizontalScrollPolicy | property |
horizontalScrollPolicy:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A property that indicates whether the horizontal scroll
bar is always on, always off,
or automatically changes based on the parameters passed to the
setScrollBarProperties() method.
Allowed values are ScrollPolicy.ON,
ScrollPolicy.OFF, and ScrollPolicy.AUTO.
MXML values can be "on", "off",
and "auto".
Setting this property to ScrollPolicy.OFF for ListBase
subclasses does not affect the horizontalScrollPosition
property; you can still scroll the contents programmatically.
Note that the policy can affect the measured size of the component
If the policy is ScrollPolicy.AUTO the
scrollbar is not factored in the measured size. This is done to
keep the layout from recalculating when the scrollbar appears. If you
know that you will have enough data for scrollbars you should set
the policy to ScrollPolicy.ON. If you
don't know, you may need to set an explicit width or height on
the component to allow for scrollbars to appear later.
The default value is ScrollPolicy.OFF.
This property can be used as the source for data binding. When this property is modified, it dispatches the horizontalScrollPolicyChanged event.
Implementation
public function get horizontalScrollPolicy():String public function set horizontalScrollPolicy(value:String):voidhorizontalScrollPosition | property |
horizontalScrollPosition:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The offset into the content from the left edge. This can be a pixel offset in some subclasses or some other metric like the number of columns in a DataGrid or number of items in a HorizontalList or TileList.
The default value is 0.
This property can be used as the source for data binding. When this property is modified, it dispatches the viewChanged event.
Implementation
public function get horizontalScrollPosition():Number public function set horizontalScrollPosition(value:Number):voidliveScrolling | property |
public var liveScrolling:Boolean = true| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates whether scrolling is live as the
scrollbar thumb is moved
or the view is not updated until the thumb is released.
The default value is true.
maskShape | property |
protected var maskShape:Shape| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The mask. This property may be undefined if no scroll bars
are currently displayed or in some subclasses which
have a different masking mechanism.
A mask defined the viewable area of a displayable object.
Thus this mask is used to hide the portions of the content
that are not currently viewable.
In general you do not access this property directly.
Manipulation of the horizontalScrollPolicy,
verticalScrollPolicy, horizontalScrollPosition,
and verticalScrollPosition properties
should provide sufficient control over the mask.
maxHorizontalScrollPosition | property |
maxHorizontalScrollPosition:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The maximum value for the horizontalScrollPosition property.
Note that this is not the width of the content because the
maxHorizontalScrollPosition property contains the width
of the content minus the width of the displayable area.
In most components, the value of the
maxHorizontalScrollPosition property is computed from the
data and size of component, and must not be set by
the application code.
This property can be used as the source for data binding. When this property is modified, it dispatches the maxHorizontalScrollPositionChanged event.
Implementation
public function get maxHorizontalScrollPosition():Number public function set maxHorizontalScrollPosition(value:Number):voidmaxVerticalScrollPosition | property |
maxVerticalScrollPosition:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The maximum value for the verticalScrollPosition property.
Note that this is not the height of the content because the
maxVerticalScrollPosition property contains the height
of the content minus the height of the displayable area.
The value of the
maxVerticalScrollPosition property is computed from the
data and size of component, and must not be set by
the application code.
This property can be used as the source for data binding. When this property is modified, it dispatches the maxVerticalScrollPositionChanged event.
Implementation
public function get maxVerticalScrollPosition():Number public function set maxVerticalScrollPosition(value:Number):voidscrollAreaChanged | property |
protected var scrollAreaChanged:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that the scrolling area changed due to the appearance or disappearance of scrollbars. Used by most layout methods to re-adjust the scrolling properties again.
scrollTipFunction | property |
scrollTipFunction:Function| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A function that computes the string to be displayed as the ScrollTip.
This function is called if the showScrollTips property
is set to true and the scroll thumb is being dragged.
The function should return a String that used as a ScrollTip.
The function is passed two parameters.
The first is the direction of the scroll bar.
The second is its scrollPosition, as the following example shows:
function scrollTipFunction(direction:String, position:Number):String
{
if (direction == "vertical") return myToolTips[position];
else return "";
}
This property can be used as the source for data binding. When this property is modified, it dispatches the scrollTipFunctionChanged event.
Implementation
public function get scrollTipFunction():Function public function set scrollTipFunction(value:Function):voidshowScrollTips | property |
public var showScrollTips:Boolean = false| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates whether a tooltip should appear
near the scroll thumb when it is being dragged.
The default value is false to disable the tooltip.
verticalScrollBar | property |
protected var verticalScrollBar:ScrollBar| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The vertical scroll bar.
This property is null if no vertical scroll bar
is currently displayed.
In general you do not access this property directly.
Manipulation of the verticalScrollPolicy
and verticalScrollPosition
properties should provide sufficient control over the scroll bar.
verticalScrollPolicy | property |
verticalScrollPolicy:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A property that indicates whether the vertical scroll bar is always on, always off,
or automatically changes based on the parameters passed to the
setScrollBarProperties() method.
Allowed values are ScrollPolicy.ON,
ScrollPolicy.OFF, and ScrollPolicy.AUTO.
MXML values can be "on", "off",
and "auto".
Setting this property to ScrollPolicy.OFF for ListBase
subclasses does not affect the verticalScrollPosition
property; you can still scroll the contents programmatically.
Note that the policy can affect the measured size of the component
If the policy is ScrollPolicy.AUTO the
scrollbar is not factored in the measured size. This is done to
keep the layout from recalculating when the scrollbar appears. If you
know that you will have enough data for scrollbars you should set
the policy to ScrollPolicy.ON. If you
don't know, you may need to set an explicit width or height on
the component to allow for scrollbars to appear later.
The default value is ScrollPolicy.AUTO.
This property can be used as the source for data binding. When this property is modified, it dispatches the verticalScrollPolicyChanged event.
Implementation

verticalScrollPosition:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The offset into the content from the top edge. This can be a pixel offset in some subclasses or some other metric like number of lines in a List or number of tiles in a TileList.
The default value is 0.
This property can be used as the source for data binding. When this property is modified, it dispatches the viewChanged event.

Constructor.
Method Detail
createBorder | () | method |
protected function createBorder():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Creates the border for this component.
Normally the border is determined by the
borderStyle and borderSkin styles.
It must set the border property to the instance
of the border.
createChildren | () | method |
override protected function createChildren():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Creates objects that are children of this ScrollControlBase,
which in this case are the border and mask.
Flex calls this method when the ScrollControlBase is first created.
If a subclass overrides this method, the subclass should call
the super.createChildren() method so that the logic
in the ScrollControlBase.createChildren() method is executed.
layoutChrome | () | method |
protected function layoutChrome(unscaledWidth:Number, unscaledHeight:Number):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Responds to size changes by setting the positions and sizes of this control's borders.
The ScrollControlBase.layoutChrome() method sets the
position and size of the ScrollControlBase's border.
In every subclass of ScrollControlBase, the subclass's layoutChrome()
method should call the super.layoutChrome() method,
so that the border is positioned properly.
Parameters
unscaledWidth:Number — Specifies the width of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleX property of the component.
| |
unscaledHeight:Number — Specifies the height of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleY property of the component.
|
mouseWheelHandler | () | method |
protected function mouseWheelHandler(event:MouseEvent):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
