	使用 Flex 4.0 開始，Adobe 建議您使用 spark.components.BorderContainer 類別當作是此類別的替代類別。
	使用 Flex 4.0 開始，Adobe 建議您使用 spark.components.VGroup 類別當作是此類別的替代類別。
	使用 Flex 4.0 開始，Adobe 建議您使用 spark.components.HGroup 類別當作是此類別的替代類別。

A Halo Box container lays out its children in a single vertical column or a single horizontal row. The direction property determines whether to use vertical (default) or horizontal layout.

Note: Adobe recommends that, when possible, you use the Spark containers with HorizontalLayout or VerticalLayout instead of the Halo Box container.

The Box class is the base class for the VBox and HBox classes. You use the <mx:Box>, <mx:VBox>, and <mx:HBox> tags to define Box containers.

A Box container has the following default sizing characteristics:

Characteristic	Description
Default size	Vertical Box The height is large enough to hold all its children at the default or explicit height of the children, plus any vertical gap between the children, plus the top and bottom padding of the container. The width is the default or explicit width of the widest child, plus the left and right padding of the container. Horizontal Box The width is large enough to hold all of its children at the default width of the children, plus any horizontal gap between the children, plus the left and right padding of the container. The height is the default or explicit height of the tallest child, plus the top and bottom padding for the container.
Default padding	0 pixels for the top, bottom, left, and right values.

measure

()

方法

override protected function measure():void

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Calculates the default sizes and minimum and maximum values of the Box container.

If the Box container's direction property is set to BoxDirection.HORIZONTAL, its measuredWidth property is equal to the sum of default widths of all of its children, plus the thickness of the borders, plus the left and right padding, plus the horizontal gap between each child. The value of the measuredHeight property is the maximum of all the children's default heights, plus room for the borders and padding. If the Box container's direction property is set to BoxDirection.VERTICAL, these two values are reversed.

The Box container's minWidth and minHeight properties are calculated similarly, by combining the minimum widths and minimum heights of the children. If the child's width property is a percentage value, the Box container's minimum width is equal to the value of the child's minWidth property. If the child's width is unset or set to a fixed value, the child refuses to grow or shrink, so the Box container's minimum width is equal to the value of the child's explicitWidth property. The child's minimum height is calculated similarly.

The Box container's maxWidth and maxHeight properties are not calculated. The Box container is assumed to have an infinite maximum width and height.

All of the values described previously are the measured widths and heights of the Box container. The user can override the measured values by explicitly supplying a value for the following properties:

width
height
minWidth
minHeight
maxWidth
maxHeight

You should not call the measure() method directly. The Flex LayoutManager calls it at the appropriate time. At application startup, the Flex LayoutManager attempts to measure all components from the children to the parents before setting them to their final sizes.

This is an advanced method for use in subclassing. If you override this method, your implementation must call the super.measure() method, or set the measuredHeight and measuredWidth properties. You may also optionally set the following properties:

measuredMinWidth
measuredMinHeight

These properties correspond to the layout properties listed previously and, therefore, are not separately documented.

pixelsToPercent

()

方法

public function pixelsToPercent(pxl:Number):Number

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Method used to convert number of pixels to a percentage relative to the contents of this container.

The percentage value is relevant only while the container does not change size or layout. After a resize and/or new layout has occurred, the value returned from this method may be stale.

An example of how this method could be used would be to restore a component's size to a specific number of pixels after hiding it.

參數

pxl:Number — The number of pixels for which a percentage value is desired.

傳回值

Number — The percentage value that would be equivalent to pxl under the current layout conditions of this container. A negative value indicates that the container must grow in order to accommodate the requested size.

updateDisplayList

()

方法

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

語言版本:

ActionScript 3.0

產品版本:

Flex 3

執行階段版本:

Flash Player 9, AIR 1.1

Sets the size and position of each child of the Box container.

To understand the layout algorithm for the Box container, assume that the Box container's direction is horizontal.

All of the Box container's children are positioned side-by-side in a single horizontal row, with horizontalGap pixels between each pair of adjacent children. Initially, the widths of children without an explicit width value are set equal to the values of their measuredWidth properties.

If the sum of the values of the measuredWidth properties of the children is greater than or less than the width of the Box container, and if some of the children have a percentage value for the width property, the sizes of those children are grown or shrunk until all children exactly fit in the Box. However, no child is shrunk to less than the value of its minWidth property or increased greater than the value of its maxWidth property. Among the growing (or shrinking) children, extra space is added (or removed) in proportion to the child's percentWidth. For example, a child with a percentWidth of 40 percent will grow twice as much as a child with a percentWidth of 20 percent until all of the available space is filled or the prescribed sizes are reached.

After all flexible children have grown or shrunk, Flex checks to see if the sum of the children's widths match the width of the Box container. If not, the group of children are all shifted according to the value of the Box container's horizontalAlign property, so the children are aligned with the left edge of the Box, aligned with the right edge of the Box, or centered in the middle of the Box.

To determine the height of each child, Flex examines the value of the child's height property. If the height is unset, the child's height is set to its measuredHeight. If the height is set to a pixel value, that value is used. If the height is set to a percentage value, the child's height is grown or shrunk to match the specified percentage of the height of the Box, as long as the child's height is not shrunk to less than the value of its minHeight property or grown to be larger than the value of its maxHeight property.

The vertical position of each child is determined by the Box container's verticalAlign property. Each child is shifted so that it is aligned with the top edge of the box, aligned with the bottom edge of the box, or centered in the Box.

If the Box container's direction is vertical, the same rules apply, except that the widths and heights are swapped. The children are arranged in a single vertical column.

You should not call this method directly. The Flex LayoutManager calls it at the appropriate time. At application startup, the Flex LayoutManager calls the updateDisplayList() method on every component, starting with the Application object and working downward.

This is an advanced method for use in subclassing. If you override this method, your implementation should call the super.updateDisplayList() method and call the move() and setActualSize() methods on each of the children. For the purposes of performing layout, you should get the size of this container from the unscaledWidth and unscaledHeight properties, not the width and height properties. The width and height properties do not take into account the values of the scaleX and scaleY properties for this container.

參數

	`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.
