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.

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.

 InheritedType: 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.

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.

justificationRule

Legal values are flashx.textLayout.formats.JustificationRule.EAST_ASIAN, flashx.textLayout.formats.JustificationRule.SPACE, flashx.textLayout.formats.FormatValue.AUTO, flashx.textLayout.formats.FormatValue.INHERIT.

maskType

property 
maskType:String

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

The mask type. Possible values are MaskType.CLIP, MaskType.ALPHA or MaskType.LUMINOSITY.

Clip Masking

When masking in clip mode, a clipping masks is reduced to 1-bit. This means that a mask will not affect the opacity of a pixel in the source content; it either leaves the value unmodified, if the corresponding pixel in the mask is has a non-zero alpha value, or makes it fully transparent, if the mask pixel value has an alpha value of zero.

Alpha Masking

In alpha mode, the opacity of each pixel in the source content is multiplied by the opacity of the corresponding region of the mask. i.e., a pixel in the source content with an opacity of 1 that is masked by a region of opacity of .5 will have a resulting opacity of .5. A source pixel with an opacity of .8 masked by a region with opacity of .5 will have a resulting opacity of .4.

Luminosity Masking

A luminosity mask, sometimes called a 'soft mask', works very similarly to an alpha mask except that both the opacity and RGB color value of a pixel in the source content is multiplied by the opacity and RGB color value of the corresponding region in the mask.

Luminosity masking is not native to Flash but is common in Adobe Creative Suite tools like Adobe Illustrator and Adobe Photoshop. In order to accomplish the visual effect of a luminosity mask in Flash-rendered content, a graphic element specifying a luminosity mask actually instantiates a shader filter that mimics the visual look of a luminosity mask as rendered in Adobe Creative Suite tools.

Objects being masked by luminosity masks can set properties to control the RGB color value and clipping of the mask. See the luminosityInvert and luminosityClip attributes.

The default value is MaskType.CLIP.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.

Constructor Detail

GroupBase

()Constructor
public function GroupBase()

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Constructor.

Method Detail

createChildren

()method
override protected function createChildren():void

Create child objects of the component. This is an advanced method that you might override when creating a subclass of UIComponent.

A component that creates other components or objects within it is called a composite component. For example, the Flex ComboBox control is actually made up of a TextInput control to define the text area of the ComboBox, and a Button control to define the ComboBox arrow. Components implement the createChildren() method to create child objects (such as other components) within the component.

From within an override of the createChildren() method, you call the addChild() method to add each child object.

You do not call this method directly. Flex calls the createChildren() method in response to the call to the addChild() method to add the component to its parent.

getElementAt

()method 
public function getElementAt(index:int):IVisualElement

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Returns the visual element at the specified index.

Parameters

index:int — The index of the element to retrieve.

Returns
IVisualElement — The element at the specified index.

getElementIndex

()method 
public function getElementIndex(element:IVisualElement):int

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Returns the index position of a visual element.

Parameters

element:IVisualElement — The visual element.

Returns
int — The index position of the element in the container.

getHorizontalScrollPositionDelta

()method 
public function getHorizontalScrollPositionDelta(navigationUnit:uint):Number

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Returns the change to the horizontal scroll position to handle different scrolling options. These options are defined by the NavigationUnit class: END, HOME, LEFT, PAGE_LEFT, PAGE_RIGHT, and RIGHT.

Parameters

navigationUnit:uint — Takes the following values:
  • END Returns scroll delta that will right justify the scrollRect to the content area.
  • HOME Returns scroll delta that will left justify the scrollRect to the content area.
  • LEFT Returns scroll delta that will left justify the scrollRect with the first element that spans or is to the left of the scrollRect's left edge.
  • PAGE_LEFT Returns scroll delta that will right justify the scrollRect with the first element that spans or is to the left of the scrollRect's left edge.
  • PAGE_RIGHT Returns scroll delta that will left justify the scrollRect with the first element that spans or is to the right of the scrollRect's right edge.
  • RIGHT Returns scroll delta that will right justify the scrollRect with the first element that spans or is to the right of the scrollRect's right edge.
The implementation calls getElementBoundsLeftOfScrollRect() and getElementBoundsRightOfScrollRect() to determine the bounds of the elements. Layout classes usually override those methods instead of getHorizontalScrollPositionDelta().

Returns
Number

getVerticalScrollPositionDelta

()method 
public function getVerticalScrollPositionDelta(navigationUnit:uint):Number

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Returns the change to the horizontal scroll position to handle different scrolling options. These options are defined by the NavigationUnit class: DOWN, END, HOME, PAGE_DOWN, PAGE_UP, and UP.

Parameters

navigationUnit:uint — Takes the following values:
  • DOWN Returns scroll delta that will bottom justify the scrollRect with the first element that spans or is below the scrollRect's bottom edge.
  • END Returns scroll delta that will bottom justify the scrollRect to the content area.
  • HOME Returns scroll delta that will top justify the scrollRect to the content area.
  • PAGE_DOWN Returns scroll delta that will top justify the scrollRect with the first element that spans or is below the scrollRect's bottom edge.
  • PAGE_UP
  • Returns scroll delta that will bottom justify the scrollRect with the first element that spans or is above the scrollRect's top edge.
  • UP Returns scroll delta that will top justify the scrollRect with the first element that spans or is above the scrollRect's top edge.
The implementation calls getElementBoundsAboveScrollRect() and getElementBoundsBelowScrollRect() to determine the bounds of the elements. Layout classes usually override those methods instead of getVerticalScrollPositionDelta().

Returns
Number

getVirtualElementAt

()method 
public function getVirtualElementAt(index:int, eltWidth:Number = NaN, eltHeight:Number = NaN):IVisualElement

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Layouts that honor the useVirtualLayout flag will use this method at updateDisplayList() time to get layout elements that are "in view", i.e. that overlap the Group's scrollRect.

If the element to be returned wasn't already a visible child, i.e. if it was created or recycled, and either eltWidth or eltHeight is specified, then the element's initial size is set with setLayoutBoundsSize() before it's validated. This is important for components, like text, that reflow when the layout is justified to the Group's width or height.

The returned layout element will have been validated.

This method will lazily create or "recycle" and validate layout elements as needed.

This method is not intended to be called directly, layouts that support virutalization will call it.

Parameters

index:int — The index of the element to retrieve.
 
eltWidth:Number (default = NaN) — If specified, the newly created or recycled element's initial width.
 
eltHeight:Number (default = NaN) — If specified, the newly created or recycled element's initial height.

Returns
IVisualElement — The validated element at the specified index.

setContentSize

()method 
public function setContentSize(width:Number, height:Number):void

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Sets the contentWidth and contentHeight properties. This method is intended for layout class developers who should call it from updateDisplayList() methods.

Parameters

width:Number — The new value of contentWidth.
 
height:Number — The new value of contentHeight.
