The Container class is an abstract base class for components that controls the layout characteristics of child components. You do not create an instance of Container in an application. Instead, you create an instance of one of Container's subclasses, such as Canvas or HBox.

The Container class contains the logic for scrolling, clipping, and dynamic instantiation. It contains methods for adding and removing children. It also contains the getChildAt() method, and the logic for drawing the background and borders of containers.

The default button skin uses this color to tint the background. Slider track highlighting uses this color. Il valore predefinito è `#0099FF`.	Container
backgroundAlpha	Tipo: Number Ereditarietà CSS: No Tema: halo, spark Versione linguaggio: ActionScript 3.0 Versione prodotto: Flex 3 Versioni runtime: Flash9, AIR 1.1 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. Il valore predefinito è `1.0`.	Container
backgroundColor	Tipo: uint Formato: Color Ereditarietà CSS: No Tema: halo, spark Versione linguaggio: ActionScript 3.0 Versione prodotto: Flex 3 Versioni runtime: Flash9, AIR 1.1 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 `fillAlphas` property to 1, as the following example shows: <mx:Container backgroundColor="0x66CC66"/> <mx:ControlName ... fillAlphas="[1,1]"/> </mx:Container>	Container

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 `fillAlphas` property to 1, as the following example shows: <mx:Container backgroundColor="0x66CC66"/> <mx:ControlName ... fillAlphas="[1,1]"/> </mx:Container>	Container

A ProgressBar is filled with a vertical gradient between this color and a brighter color computed from it. This style has no effect on other components, but can be set on a container to control the appearance of all progress bars found within. The default value is `undefined`, which means it is not set. In this case, the `themeColor` style property is used.	Container
borderColor	Tipo: uint Formato: Color Ereditarietà CSS: No Tema: halo, spark Versione linguaggio: ActionScript 3.0 Versione prodotto: Flex 3 Versioni runtime: Flash9, AIR 1.1 Color of the border.

Descrizione delle proprietà

actualCreationPolicy

proprietà

protected var actualCreationPolicy:String

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

The creation policy of this container.

autoLayout

proprietà

autoLayout:Boolean

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

If true, measurement and layout are done when the position or size of a child is changed. If false, measurement and layout are done only once, when children are added to or removed from the container.

When using the Move effect, the layout around the component that is moving does not readjust to fit that the Move effect animates. Setting a container's autoLayout property to true has no effect on this behavior.

The Zoom effect does not work when the autoLayout property is false.

The autoLayout property does not apply to Accordion or ViewStack containers.

Il valore predefinito è true.

Implementazione
public function get autoLayout():Boolean
public function set autoLayout(value:Boolean):void

borderMetrics

proprietà

borderMetrics:EdgeMetrics [sola lettura]

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

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.

Unlike viewMetrics, this property is not overridden by subclasses of Container.

childDescriptors

proprietà

childDescriptors:Array [sola lettura]

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Array of UIComponentDescriptor objects produced by the MXML compiler.

Each UIComponentDescriptor object contains the information specified in one child MXML tag of the container's MXML tag. The order of the UIComponentDescriptor objects in the Array is the same as the order of the child tags. During initialization, the child descriptors are used to create the container's child UIComponent objects and its Repeater objects, and to give them the initial property values, event handlers, effects, and so on, that were specified in MXML.

public function get creationIndex():int
public function set creationIndex(value:int):void

creationPolicy

proprietà

creationPolicy:String

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

The child creation policy for this MX Container. ActionScript values can be ContainerCreationPolicy.AUTO, ContainerCreationPolicy.ALL, or ContainerCreationPolicy.NONE. MXML values can be auto, all, or none.

If no creationPolicy is specified for a container, that container inherits its parent's creationPolicy. If no creationPolicy is specified for the Application, it defaults to ContainerCreationPolicy.AUTO.

A creationPolicy of ContainerCreationPolicy.AUTO means that the container delays creating some or all descendants until they are needed, a process which is known as deferred instantiation. This policy produces the best startup time because fewer UIComponents are created initially. However, this introduces navigation delays when a user navigates to other parts of the application for the first time. Navigator containers such as Accordion, TabNavigator, and ViewStack implement the ContainerCreationPolicy.AUTO policy by creating all their children immediately, but wait to create the deeper descendants of a child until it becomes the selected child of the navigator container.

A creationPolicy of ContainerCreationPolicy.ALL means that the navigator containers immediately create deeper descendants for each child, rather than waiting until that child is selected. For single-view containers such as a VBox container, there is no difference between the ContainerCreationPolicy.AUTO and ContainerCreationPolicy.ALL policies.

A creationPolicy of ContainerCreationPolicy.NONE means that the container creates none of its children. In that case, it is the responsibility of the MXML author to create the children by calling the createComponentsFromDescriptors() method.

Il valore predefinito è ContainerCreationPolicy.AUTO.

Implementazione

rawChildren

proprietà

rawChildren:IChildList [sola lettura]

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

A container typically contains child components, which can be enumerated using the Container.getChildAt() method and Container.numChildren property. In addition, the container may contain style elements and skins, such as the border and background. Flash Player and AIR do not draw any distinction between child components and skins. They are all accessible using the player's getChildAt() method and numChildren property. However, the Container class overrides the getChildAt() method and numChildren property (and several other methods) to create the illusion that the container's children are the only child components.

If you need to access all of the children of the container (both the content children and the skins), then use the methods and properties on the rawChildren property instead of the regular Container methods. For example, use the Container.rawChildren.getChildAt()) method. However, if a container creates a ContentPane Sprite object for its children, the rawChildren property value only counts the ContentPane, not the container's children. It is not always possible to determine when a container will have a ContentPane.

Note:If you call the addChild or addChildAt method of the rawChildren object, set tabFocusEnabled = false on the component that you have added. Doing so prevents users from tabbing to the visual-only component that you have added.

Specifies whether the vertical scroll bar is always present, always absent, or automatically added when needed. Possible values are ScrollPolicy.ON, ScrollPolicy.OFF, and ScrollPolicy.AUTO. MXML values can be "on", "off", and "auto".

Setting this property to ScrollPolicy.OFF also prevents the verticalScrollPosition property from having an effect.

Note: This property does not apply to the ControlBar container.

If the verticalScrollPolicy is ScrollPolicy.AUTO, the vertical scroll bar appears when all of the following are true:

One of the container's children extends beyond the top edge or bottom edge of the container.
The clipContent property is true.
The width and height of the container are large enough to reasonably accommodate a scroll bar.

viewMetrics

proprietà

viewMetrics:EdgeMetrics [sola lettura]

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Returns an object that has four properties: left, top, right, and bottom. The value of each property equals the thickness of the chrome (visual elements) around the edge of the container.

The chrome includes the border thickness. If the horizontalScrollPolicy or verticalScrollPolicy property value is ScrollPolicy.ON, the chrome also includes the thickness of the corresponding scroll bar. If a scroll policy is ScrollPolicy.AUTO, the chrome measurement does not include the scroll bar thickness, even if a scroll bar is displayed.

Subclasses of Container should override this method, so that they include other chrome to be taken into account when positioning the Container's children. For example, the viewMetrics property for the Panel class should return an object whose top property includes the thickness of the Panel container's title bar.

Descrizione dei metodi

addChild

()

metodo

override public function addChild(child:DisplayObject):DisplayObject

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Adds a child DisplayObject to this Container. The child is added after other existing children, so that the first child added has index 0, the next has index 1, an so on.

Note: While the child argument to the method is specified as of type DisplayObject, the argument must implement the IUIComponent interface to be added as a child of a container. All Flex components implement this interface.

Children are layered from back to front. In other words, if children overlap, the one with index 0 is farthest to the back, and the one with index numChildren - 1 is frontmost. This means the newly added children are layered in front of existing children.

Parametri

child:DisplayObject — The DisplayObject to add as a child of this Container. It must implement the IUIComponent interface.

Restituisce

DisplayObject — The added child as an object of type DisplayObject. You typically cast the return value to UIComponent, or to the type of the added component.

override public function addChildAt(child:DisplayObject, index:int):DisplayObject

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Adds a child DisplayObject to this Container. The child is added at the index specified.

When you add a new child at an index that is already occupied by an old child, it doesn't replace the old child; instead the old child and the ones after it "slide over" and have their index incremented by one. For example, suppose a Container contains the children (A, B, C) and you add D at index 1. Then the container will contain (A, D, B, C). If you want to replace an old child, you must first remove it before adding the new one.

Parametri

	`child:DisplayObject` — The DisplayObject to add as a child of this Container. It must implement the IUIComponent interface.

	`index:int` — The index to add the child at.

Restituisce

DisplayObject — The added child as an object of type DisplayObject. You typically cast the return value to UIComponent, or to the type of the added component.

createComponentFromDescriptor

()

metodo

public function createComponentFromDescriptor(descriptor:ComponentDescriptor, recurse:Boolean):IFlexDisplayObject

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Given a single UIComponentDescriptor, create the corresponding component and add the component as a child of this Container.

This method instantiates the new object but does not add it to the display list, so the object does not appear on the screen by default. To add the new object to the display list, call the validateNow() method on the container after calling the createComponentFromDescriptor() method, as the following example shows:

      myVBox.createComponentFromDescriptor(myVBox.childDescriptors[0],false);
      myVBox.validateNow();

Alternatively, you can call the createComponentsFromDescriptors() method on the container to create all components at one time. You are not required to call the validateNow() method after calling the createComponentsFromDescriptors() method.

Parametri

	`descriptor:ComponentDescriptor` — The UIComponentDescriptor for the component to be created. This argument is either a UIComponentDescriptor object or the index of one of the container's children (an integer between 0 and n-1, where n is the total number of children of this container).

	`recurse:Boolean` — If `false`, create this component but none of its children. If `true`, after creating the component, Flex calls the `createComponentsFromDescriptors()` method to create all or some of its children, based on the value of the component's `creationPolicy` property.

Restituisce

IFlexDisplayObject — The created component.

()

metodo

public function createComponentsFromDescriptors(recurse:Boolean = true):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Iterate through the Array of childDescriptors, and call the createComponentFromDescriptor() method for each one.

If the value of the container's creationPolicy property is ContainerCreationPolicy.ALL, then this method is called automatically during the initialization sequence.

If the value of the container's creationPolicy is ContainerCreationPolicy.AUTO, then this method is called automatically when the container's children are about to become visible.

If the value of the container's creationPolicy property is ContainerCreationPolicy.NONE, then you should call this function when you want to create this container's children.

executeBindings

()

metodo

override public function executeBindings(recurse:Boolean = false):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Executes all the data bindings on this Container. Flex calls this method automatically once a Container has been created to cause any data bindings that have destinations inside of it to execute. Workaround for MXML container/bindings problem (177074): override Container.executeBindings() to prefer descriptor.document over parentDocument in the call to BindingManager.executeBindings(). This should always provide the correct behavior for instances created by descriptor, and will provide the original behavior for procedurally-created instances. (The bug may or may not appear in the latter case.) A more complete fix, guaranteeing correct behavior in both non-DI and reparented-component scenarios, is anticipated for updater 1.

Parametri

recurse:Boolean (default = false) — If false, then only execute the bindings on this Container. If true, then also execute the bindings on this container's children, grandchildren, great-grandchildren, and so on.

Gets the nth child component object.

The children returned from this method include children that are declared in MXML and children that are added using the addChild() or addChildAt() method.

Parametri

index:int — Number from 0 to (numChildren - 1).

getChildIndex

()

metodo

override public function getChildIndex(child:DisplayObject):int

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Gets the zero-based index of a specific child.

The first child of the container (i.e.: the first child tag that appears in the MXML declaration) has an index of 0, the second child has an index of 1, and so on. The indexes of a container's children determine the order in which they get laid out. For example, in a VBox the child with index 0 is at the top, the child with index 1 is below it, etc.

If you add a child by calling the addChild() method, the new child's index is equal to the largest index among existing children plus one. You can insert a child at a specified index by using the addChildAt() method; in that case the indices of the child previously at that index, and the children at higher indices, all have their index increased by 1 so that all indices fall in the range from 0 to (numChildren - 1).

If you remove a child by calling removeChild() or removeChildAt() method, then the indices of the remaining children are adjusted so that all indices fall in the range from 0 to (numChildren - 1).

If myView.getChildIndex(myChild) returns 5, then myView.getChildAt(5) returns myChild.

The index of a child may be changed by calling the setChildIndex() method.

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Respond to size changes by setting the positions and sizes of this container's borders. This is an advanced method that you might override when creating a subclass of Container.

Flex calls the layoutChrome() method when the container is added to a parent container using the addChild() method, and when the container's invalidateDisplayList() method is called.

The Container.layoutChrome() method is called regardless of the value of the autoLayout property.

The Container.layoutChrome() method sets the position and size of the Container container's border. In every subclass of Container, the subclass's layoutChrome() method should call the super.layoutChrome() method, so that the border is positioned properly.

Parametri

	`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.

childAdd

Evento

Tipo di oggetto evento: mx.events.ChildExistenceChangedEvent
proprietà ChildExistenceChangedEvent.type = mx.events.ChildExistenceChangedEvent.CHILD_ADD

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Dispatched after a child has been added to a container.

The childAdd event is dispatched when the addChild() or addChildAt() method is called. When a container is first created, the addChild() method is automatically called for each child component declared in the MXML file. The addChildAt() method is automatically called whenever a Repeater object adds or removes child objects. The application developer may also manually call these methods to add new children.

At the time when this event is sent, the child object has been initialized, but its width and height have not yet been calculated, and the child has not been drawn on the screen. If you want to be notified when the child has been fully initialized and rendered, then register as a listener for the child's creationComplete event.

The ChildExistenceChangedEvent.CHILD_ADD constant defines the value of the type property of the event object for a childAdd event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`relatedObject`	Contains a reference to the child object that was created.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.

Versioni runtime:

Flash Player 9, AIR 1.1

Dispatched after the index (among the container children) of a container child changes. This event is only dispatched for the child specified as the argument to the setChildIndex() method; it is not dispatched for any other child whose index changes as a side effect of the call to the setChildIndex() method.

The child's index is changed when the setChildIndex() method is called.

The IndexChangedEvent.CHILD_INDEX_CHANGE constant defines the value of the type property of the event object for a childIndexChange event, which indicates that a component's index among a container's children has changed.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`inputType`	Indicates whether this event was caused by a mouse or keyboard interaction.
`newIndex`	The zero-based index of the child after the change.
`oldIndex`	The zero-based index of the child before the change.
`relatedObject`	Contains a reference to the child object whose index changed.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
`TriggerEvent`	null
`Type`	IndexChangedEvent.CHILD_INDEX_CHANGE

This event is delivered when any of the following methods is called: removeChild(), removeChildAt(), or removeAllChildren().

The ChildExistenceChangedEvent.CHILD_REMOVE constant defines the value of the type property of the event object for a childRemove event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`relatedObject`	Contains a reference to the child object that is about to be removed.

proprietà ScrollEvent.type = mx.events.ScrollEvent.SCROLL

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Dispatched when the user manually scrolls the container.

The event is dispatched when the scroll position is changed using either the mouse (e.g. clicking on the scrollbar's "down" button) or the keyboard (e.g., clicking on the down-arrow key). However, this event is not dispatched if the scroll position is changed programatically (e.g., setting the value of the horizontalScrollPosition property). The viewChanged event is delivered whenever the scroll position is changed, either manually or programatically.

At the time when this event is dispatched, the scrollbar has been updated to the new position, but the container's child objects have not been shifted to reflect the new scroll position.

The ScrollEvent.SCROLL constant defines the value of the type property of the event object for a scroll event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`delta`	Contains the change in scroll position, expressed in pixels. A positive value indicates the scroll was down or to the right. A negative value indicates the scroll was up or to the left.
`direction`	Contains the scroll direction, either `ScrollEventDirection.HORIZONTAL` or `ScrollEventDirection.VERTICAL`.
`position`	Contains the new scroll position.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
