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. |

direction:String| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
The direction in which this Box container lays out its children.
Possible MXML values are
"horizontal" and "vertical".
Possible values in ActionScript are BoxDirection.HORIZONTAL
and BoxDirection.VERTICAL.
Standardvärdet är BoxDirection.VERTICAL.
Den här egenskapen kan användas som källan för databindning. När den här egenskapen ändras, skickas händelsen directionChanged .

Constructor.
Metoddetaljer
measure | () | metod |
override protected function measure():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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:
widthheightminWidthminHeightmaxWidthmaxHeight
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:
measuredMinWidthmeasuredMinHeight
These properties correspond to the layout properties listed previously and, therefore, are not separately documented.
pixelsToPercent | () | metod |
public function pixelsToPercent(pxl:Number):Number| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
pxl:Number — The number of pixels for which a percentage
value is desired.
|
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 | () | metod |

| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
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.
