Ao iniciar com Flex 4.0, a Adobe recomenda que você use a classe de spark.components.BorderContainer como uma alternativa a esta classe. | |
Ao iniciar com Flex 4.0, a Adobe recomenda que você use a classe de spark.components.HGroup como uma alternativa a esta classe. |
The Halo HBox container lays out its children in a single horizontal row. You use the
<mx:HBox>
tag instead of the
<mx:Box>
tag as a shortcut to avoid having to
set the direction
property to
"horizontal"
.
Note: Adobe recommends that, when possible, you use the Spark containers with HorizontalLayout instead of the Halo HBox container.
An HBox container has the following default sizing characteristics:
Characteristic | Description |
---|---|
Default size | The width is large enough to hold all its children at the default or explicit 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. |
The <mx:HBox>
tag inherits all of the tag
attributes of its superclass, except direction
, and adds
no new tag attributes.
