Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

A base class for defining individual graphic elements. Types of graphic elements include:
  • Shapes
  • Text
  • Raster images

When defining a graphic element, you specify an explicit size for the element; that is, you cannot use percentage sizing as you can when specifying the size of a control.

The TBounds are the boundaries of an object in the object's parent coordinate space. The UBounds are the boundaries of an object in its own coordinate space.

If you set the transform.matrix declaratively in MXML, then it will override the values of any transform properties (rotation, scaleX, scaleY, x, and y). If you set the transform.matrix or the transform properties in ActionScript, then the last value set will be used.

  • A value of DisplayObjectSharingMode.OWNS_SHARED_OBJECT indicates taht the IGraphicElement owns the DisplayObject corresponding to its displayObject property but other IGraphicElements are using/drawing to that display object as well. Depending on the specific implementation, the IGraphicElement may perform certain management of the display object. For example the base class GraphicElement clears the transform of the display object, reset its visibility, alpha, etc. properties to their default values and additionally clear the graphics on every validateDisplayList() call.
  • A value of DisplayObjectSharingMode.USES_SHARED_OBJECT indicates that the IGraphicElement draws into the DisplayObject corresponding to its displayObject property.

maskType

proprietà 
maskType:String

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Defines how the mask is applied to the GraphicElement.

The possible values are MaskType.CLIP, MaskType.ALPHA, and 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.

When clip masking is used, only the actual path and shape vectors and fills defined by the mask are used to determine the effect on the source content. strokes and bitmap filters defined on the mask are ignored. Any filled region in the mask is considered filled, and renders the source content. The type and parameters of the fill is irrelevant; a solid color fill, gradient fill, or bitmap fill in a mask will all render the underlying source content, regardless of the alpha values of the mask fill.

BitmapGraphics are treated as bitmap filled rectangles when used in a clipping mask. As a result, the alpha channel of the source bitmap is irrelevant when part of a mask -- the bitmap affects the mask in the same manner as solid filled rectangle of equivalent dimensions.

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.

Conceptually, alpha masking is equivalent to rendering the transformed mask and source content into separate RGBA surfaces, and multiplying the alpha channel of the mask content into the alpha channel of the source content. All of the mask content is rendered into its surface before compositing into the source content's surface. As a result, all FXG features, such as strokes, bitmap filters, and fill opacity will affect the final composited content.

When in alpha mode, the alpha channel of any bitmap data is composited normally into the mask alpha channel, and will affect the final rendered content. This holds true for both BitmapGraphics and bitmap filled shapes and paths.

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.

Conceptually, luminosity masking is equivalent to rendering the transformed mask and source content into separate RGBA surfaces, and multiplying the alpha channel and the RGB color value of the mask content into the alpha channel and RGB color value of the source content. All of the mask content is rendered into its surface before compositing into the source content's surface. As a result, all FXG features, such as strokes, bitmap filters, and fill opacity will affect the final composited content.

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.

Il valore predefinito è MaskType.CLIP.

The maximum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value of this property is set by the component developer.

The component developer uses this property to set an upper limit on the height of the component.

If the application developer overrides the default value of maxHeight, the new value is stored in explicitMaxHeight. The default value of maxHeight does not change. As a result, at layout time, if maxHeight was explicitly set by the application developer, then the value of explicitMaxHeight is used for the component's maximum recommended height. If maxHeight is not set explicitly by the user, then the default value is used.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true maxHeight with respect to its parent is affected by the scaleY property. Some components have no theoretical limit to their height. In those cases their maxHeight is set to UIComponent.DEFAULT_MAX_HEIGHT.

The maximum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value of this property is set by the component developer.

The component developer uses this property to set an upper limit on the width of the component.

If the application developer overrides the default value of maxWidth, the new value is stored in explicitMaxWidth. The default value of maxWidth does not change. As a result, at layout time, if maxWidth was explicitly set by the application developer, then the value of explicitMaxWidth is used for the component's maximum recommended width.

minHeight

proprietà 
minHeight:Number

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

The minimum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value depends on the component's implementation.

If the application developer sets the value of minHeight, the new value is stored in explicitMinHeight. The default value of minHeight does not change. As a result, at layout time, if minHeight was explicitly set by the application developer, then the value of explicitMinHeight is used for the component's minimum recommended height. If minHeight is not set explicitly by the application developer, then the value of measuredMinHeight is used.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true minHeight with respect to its parent is affected by the scaleY property.

The minimum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value depends on the component's implementation.

If the application developer sets the value of minWidth, the new value is stored in explicitMinWidth. The default value of minWidth does not change. As a result, at layout time, if minWidth was explicitly set by the application developer, then the value of explicitMinWidth is used for the component's minimum recommended width. If minWidth is not set explicitly by the application developer, then the value of measuredMinWidth is used.

Versioni runtime: Flash Player 10, AIR 1.5

True if the element requires an exclusive DisplayObject. Developers don't usually call this method directly, but override it in their subclasses to indicate that an exclusive DisplayObject is needed. Usually a subclass needs a DisplayObject when it has to set its properties. Some examples of such DisplayObject properties are filters, blendMode, mask, rotation, alpha.

owner

proprietà 
owner:DisplayObjectContainer

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

The owner of this IVisualElement object. By default, it is the parent of this IVisualElement object. However, if this IVisualElement object is a child component that is popped up by its parent, such as the drop-down list of a ComboBox control, the owner is the component that popped up this IVisualElement object.

This property is not managed by Flex, but by each component. Therefore, if you use the PopUpManger.createPopUp() or PopUpManger.addPopUp() method to pop up a child component, you should set the owner property of the child component to the component that popped it up.

The default value is the value of the parent property.

percentHeight

proprietà 
percentHeight:Number

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Specifies the height of a component as a percentage of its parent's size. Allowed values are 0-100. Setting the height or explicitHeight properties resets this property to NaN.

This property returns a numeric value only if the property was previously set; it does not reflect the exact size of the component in percent.

percentWidth

proprietà 
percentWidth:Number

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Specifies the width of a component as a percentage of its parent's size. Allowed values are 0-100. The default value is NaN. Setting the width or explicitWidth properties resets this property to NaN.

This property returns a numeric value only if the property was previously set; it does not reflect the exact size of the component in percent.

This property is always set to NaN for the UITextField control.

When used with Spark layouts, this property is used to calculate the width of the component's bounds after scaling and rotation. For example if the component is rotated at 90 degrees, then specifying percentWidth will affect the component's height.

transform

proprietà 
transform:flash.geom:Transform

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Un oggetto con proprietà relative alla matrice, alla trasformazione del colore e ai limiti di pixel di un oggetto di visualizzazione. Le proprietà specifiche matrix, colorTransform e tre proprietà di sola lettura (concatenatedMatrix, concatenatedColorTransform e pixelBounds) sono descritte nella voce relativa alla classe Transform.

Ognuna delle proprietà dell'oggetto di trasformazione è, essa stessa, un oggetto. Questo concetto è importante, poiché il solo modo per impostare nuovi valori per gli oggetti matrix o colorTransform consiste nel creare un nuovo oggetto e copiarlo nella proprietà transform.matrix o transform.colorTransform.

Ad esempio, per aumentare il valore tx della matrice di un oggetto di visualizzazione, dovete creare una copia dell'intero oggetto matrice, quindi copiare il nuovo oggetto nella proprietà matrix dell'oggetto di trasformazione:


    var myMatrix:Matrix = myDisplayObject.transform.matrix;  
    myMatrix.tx += 10; 
    myDisplayObject.transform.matrix = myMatrix;  
    

Non è possibile impostare direttamente la proprietà tx. Il codice seguente non ha effetto su myDisplayObject:


    myDisplayObject.transform.matrix.tx += 10;
    

Potete inoltre copiare un intero oggetto di trasformazione e assegnarlo alla proprietà di trasformazione di un altro oggetto di visualizzazione. Ad esempio, il codice seguente copia l'intero oggetto di trasformazione da myOldDisplayObj a myNewDisplayObj:

myNewDisplayObj.transform = myOldDisplayObj.transform;

L'oggetto di visualizzazione ottenuto, myNewDisplayObj, presenta ora gli stessi valori dell'oggetto di visualizzazione precedente (myOldDisplayObj) per la matrice, la trasformazione del colore e i limiti dei pixel.

Nota: i dispositivi AIR per TV utilizzano l'accelerazione hardware, se disponibile, per le trasformazioni di colore.

The vertical distance in pixels from the center of the component to the center of the anchor target's content area.

The default anchor target is the container itself.

In layouts with advanced constraints, the anchor target can be a constraint row. Then the content area is the space between the preceding row (or container side) and the target row.

Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Returns true if this IGraphicElement is compatible and can share display objects with the next IGraphicElement in the sequence.

Parametri

element:IGraphicElement — The element that comes after this element in the sequence.

Restituisce
Boolean — Returns true when this element is compatible with the previous element in the sequence.

canShareWithPrevious

()metodo 
public function canShareWithPrevious(element:IGraphicElement):Boolean

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Returns true if this IGraphicElement is compatible and can share display objects with the previous IGraphicElement in the sequence.

In certain cases the element might be passed to the IGraphicElementContainer in a call to the setSharedDisplayObject() method. In those cases, this method is not called.

Parametri

element:IGraphicElement — The element that comes before this element in the sequence.

Restituisce
Boolean — Returns true when this element is compatible with the previous element in the sequence.

canSkipMeasurement

()metodo 
protected function canSkipMeasurement():Boolean

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Determines if the call to the measure() method can be skipped.

Restituisce
Boolean — Returns true when the measureSizes() method can skip the call to the measure() method. For example this is usually true when both the explicitWidth and explicitHeight properties are set. For paths, this is true when the bounds of the path have not changed.

commitProperties

()metodo 
protected function commitProperties():void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Processes the properties set on the element. This is an advanced method that you might override when creating a subclass.

You do not call this method directly. Flex calls the commitProperties() method when you use the addElement() method to add an element to an IGraphicElementContainer container such as Group, or when you call the invalidateProperties() method of the element. Calls to the commitProperties() method occur before calls to the measure() method. This lets you set property values that might be used by the measure() method.

Some elements have properties that interact with each other. It is often best at startup time to process all of these properties at one time to avoid duplicating work.

createDisplayObject

()metodo 
public function createDisplayObject():DisplayObject

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Creates a new DisplayObject where this IGraphicElement is drawn.

Subsequent calls to the getter of the displayObject property must return the same display object.

After the DisplayObject is created, the parent IGraphicElementContainer will pass along the display objects to the rest of the elements in the sequence.

The IGraphicElementContainer ensures that this method is called only when needed.

If the element wants to participate in the DisplayObject sharing, then the new DisplayObject must implement IShareableDisplayObject. This interface is being used by the IGraphicElementContainer to manage invalidation and redrawing of the graphic element sequence and typically is not directly used by the developer.

To reevaluate the shared sequences, call the invalidateGraphicElementSharing() method on the IGraphicElementContainer.

To force the IGraphicElementContainer to remove the element's current DisplayObject from its display list and recalculate the display object sharing, call the discardDisplayObject() method on the IGraphicElementContainer.

Restituisce
DisplayObject — The display object created.

invalidateDisplayList

()metodo 
public function invalidateDisplayList():void

invalidateLayoutDirection

()metodo 
public function invalidateLayoutDirection():void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

An element must call this method when its layoutDirection changes or when its parent's layoutDirection changes. If they differ, this method is responsible for mirroring the element’s contents and for updating the element’s post-layout transform so that descendants inherit a mirrored coordinate system. IVisualElements typically implement mirroring by using postLayoutTransformOffsets to scale the X axis by -1 and to translate the x coordinate of the origin by the element's width. The net effect of this "mirror" transform is to reverse the direction in which the X axis increases without changing the element's location relative to its parent's origin.

invalidateParentSizeAndDisplayList

()metodo 
protected function invalidateParentSizeAndDisplayList():void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Helper method to invalidate parent size and display list if this object affects its layout (includeInLayout is true).

invalidateProperties

Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Calling this method results in a call to the elements's validateSize() method before the display list is rendered.

Subclasses should override and do their measurement in measure(). By default when explicitWidth and explicitHeight are set, measure() will not be called. To override this default behavior subclasses should override skipMeasure().

localToGlobal

()metodo 
public function localToGlobal(point:Point):Point

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Converts the point object from the object's (local) coordinates to the Stage (global) coordinates.

This method allows you to convert any given x and y coordinates from values that are relative to the origin (0,0) of a specific object (local coordinates) to values that are relative to the origin of the Stage (global coordinates).

To use this method, first create an instance of the Point class. The x and y values that you assign represent local coordinates because they relate to the origin of the object.

You then pass the Point instance that you created as the parameter to the localToGlobal() method. The method returns a new Point object with x and y values that relate to the origin of the Stage instead of the origin of the object.

Parametri

point:Point — The name or identifier of a point created with the Point class, specifying the x and y coordinates as properties.

Restituisce
Point — A Point object with coordinates relative to the Stage.

measure

()metodo 
protected function measure():void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Calculates the default size of the element. This is an advanced method that you might override when creating a subclass of GraphicElement.

You do not call this method directly. Flex calls the measure() method when the element is added to an IGraphicElementContainer container such as Group using the addElement() method, and when the element's invalidateSize() method is called.

By default you set both explicit height and explicit width of an element, Flex does not call the measure() method, even if you explicitly call the invalidateSize() method. To override this behavior, override skipMeasure() method.

In your override of this method, you must set the measuredWidth and measuredHeight properties to define the default size. You can optionally set the measuredX and measuredY properties to define the default measured bounds top-left corner relative to the origin of the element.

The conceptual point of measure() is for the element to provide its own natural or intrinsic bounds as a default. Therefore, the measuredWidth and measuredHeight properties should be determined by factors such as:

  • The amount of text the component needs to display.
  • The size of a JPEG image that the component displays.

In some cases, there is no intrinsic way to determine default values. For example, a simple GreenCircle element might simply set measuredWidth = 100 and measuredHeight = 100 in its measure() method to provide a reasonable default size. In other cases, such as a TextArea, an appropriate computation (such as finding the right width and height that would just display all the text and have the aspect ratio of a Golden Rectangle) might be too time-consuming to be worthwhile.

The default implementation of measure() sets the values of the measuredWidth, measuredHeight, measuredX, and measuredY properties to 0.

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Sets the coordinates that the element uses to draw on screen.

Note that calls to the setLayoutBoundSize() method can affect the layout position, so call setLayoutBoundPosition() after calling setLayoutBoundSize().

Parametri

newBoundsX:Number — The x-coordinate of the top-left corner of the bounding box.
 
newBoundsY:Number — The y-coordinate of the top-left corner of the bounding box.
 
postLayoutTransform:Boolean (default = true) — When postLayoutTransform is true, the element is positioned in such a way that the top-left corner of its bounding box is (x, y). The bounding box is in the element's parent coordinate space and is calculated from the element's layout size, layout position and layout transform matrix.

setLayoutBoundsSize

()metodo 
public function setLayoutBoundsSize(width:Number, height:Number, postLayoutTransform:Boolean = true):void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Sets the layout size of the element. This is the size that the element uses to draw on screen.

If the width and/or height parameters are left unspecified (NaN), Flex sets the element's layout size to its preferred width and/or preferred height.

Note that calls to the setLayoutBoundSize() method can affect the layout position, so call setLayoutBoundPosition() after calling setLayoutBoundSize().

Parametri

width:Number — The element's layout width.
 
height:Number — The element's layout height.
 
postLayoutTransform:Boolean (default = true) — When postLayoutTransform is true, the specified sizes are those of the element's bounding box. The bounding box is in the element's parent coordinate space and is calculated from the element's layout size, layout position, and layout transform matrix.

setLayoutMatrix

()metodo 
public function setLayoutMatrix(value:Matrix, invalidateLayout:Boolean):void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Sets the transform Matrix that is used to calculate the component's layout size and position relative to its siblings.

The matrix is typically defined by the component's 2D properties such as x, y, rotation, scaleX, scaleY, transformX, and transformY. Some components may have additional transform properties that are applied on top of the layout matrix to determine the final, computed matrix. For example UIComponent defines the offsets.

Note that layout Matrix is factored in the getPreferredSize(), getMinSize(), getMaxSize(), getLayoutSize() methods when computed in parent coordinates as well as in getLayoutPosition() in both parent and child coordinates. Layouts that calculate the transform matrix explicitly typically call this method and work with sizes in child coordinates. Layouts calling this method pass false to the invalidateLayout() method so that a subsequent layout pass is not triggered.

Parametri

value:Matrix — The matrix.
 
invalidateLayout:Booleantrue to cause the parent container to re-layout its children. You typically pass true to the invalidateLayout() method.

setLayoutMatrix3D

()metodo

This matrix is typically defined by the component's transform properties such as x, y, z, rotationX, rotationY, rotationZ, scaleX, scaleY, scaleZ, transformX, and transformY. Some components may have additional transform properties that are applied on top of the layout matrix to determine the final, computed matrix. For example UIComponent defines the offsets property.

Note that layout Matrix3D is factored in the getPreferredSize(), getMinSize(), getMaxSize(), getLayoutSize() when computed in parent coordinates as well as in getLayoutPosition() in both parent and child coordinates. Layouts that calculate the transform matrix explicitly typically call this method and work with sizes in child coordinates. Layouts calling this method pass false to the invalidateLayout() method so that a subsequent layout pass is not triggered.

Parametri

value:Matrix3D — The matrix.
 
invalidateLayout:Booleantrue to cause the parent container to re-layout its children. You typically pass true to the invalidateLayout() method.

setSharedDisplayObject

()metodo 
public function setSharedDisplayObject(sharedDisplayObject:DisplayObject):Boolean

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Determines whether this element can draw itself to the sharedDisplayObject of the sequence.

Typically implementers return true when this IGraphicElement can cumulatively draw in the shared DisplayObject graphics property. In all cases where this IGraphicElement needs to set properties on the DisplayObjects that don't apply to the rest of the elements in the sequence, this method must return false. Examples for such properties are rotation, scale, transform, mask, alpha, filters, color transform, 3D, and layer.

When this method returns true, subsequent calls to the getter of the displayObject property must return the same display object.

In certain cases, the sharedDisplayObject property might be the IGraphicElementContainer itself. In the rest of the cases, the DisplayObject is created by the first element in the sequence.

When this IGraphicElement needs to rebuild its sequence, it notifies the IGraphicElementContainer by calling its invalidateGraphicElementSharing() method.

Parametri

sharedDisplayObject:DisplayObject — The shared DisplayObject.

Restituisce
Boolean — Returns true when this IGraphicElement can draw itself to the shared DisplayObject of the sequence.

protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Draws the element and/or sizes and positions its content. This is an advanced method that you might override when creating a subclass of GraphicElement.

You do not call this method directly. Flex calls the updateDisplayList() method when the component is added to an IGraphicElementContainer container such as Group using the addElement() method, and when the element's invalidateDisplayList() method is called.

This method is where you would do programmatic drawing using methods on the elements's displayObject such as graphics.drawRect().

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Called by the IGraphicElementContainer to redraw this element in its displayObject property.

If the element is the first in the sequence (displayObjectSharingMode is set to DisplayObjectSharingMode.OWNS_SHARED_OBJECT) then it must clear the displayObject graphics and set it up as necessary for drawing the rest of the elements.

The element must alway redraw even if it itself has not changed since the last time the validateDisplayList() method was called. The parent IGraphicElementContainer will redraw the whole sequence if any of its elements need to be redrawn.

To ensure this method is called, notify the IGraphicElementContainer by calling its invalidateGraphicElementSize() method.

This method might be called even if this element has not notified the IGraphicElementContainer.

validateNow

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Used by layout logic to validate the properties of a component by calling the commitProperties() method. In general, subclasses should override the commitProperties() method and not this method.

validateSize

()metodo 
public function validateSize():void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 4
Versioni runtime: Flash Player 10, AIR 1.5

Called by the IGraphicElementContainer to validate the size of this element.

When the size of the element changes and is going to affect the IGraphicElementContainer layout, the implementer is responsible for invalidating the parent's size and display list.

To ensure that this method is called, notify the IGraphicElementContainer by calling its invalidateGraphicElementSize() method.

This method might be called even if this element has not notified the IGraphicElementContainer.
