direction | propriedade |
direction:String| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |
Direction of the FormItem subcomponents.
Possible MXML values are "vertical"
or "horizontal".
The default MXML value is "vertical".
Possible ActionScript values are FormItemDirection.VERTICAL
or FormItemDirection.HORIZONTAL.
When direction is "vertical",
the children of the FormItem are stacked vertically
to the right of the FormItem label.
When direction is "horizontal",
the children are placed in a single row (if they fit),
or in two equally-sized columns.
If you need more control over the layout of FormItem children, you can use a container such as Grid or Tile as the direct child of the FormItem and put the desired controls inside it.
O valor padrão é FormItemDirection.VERTICAL.

| Versões de runtime: | Flash Player 9, AIR 1.1 |
Calculates the preferred, minimum and maximum sizes of the FormItem.
See the UIComponent.measure() method for more information
about the measure() method.
The FormItem.measure() method first determines
the number of columns to use.
If the direction property is
FormItemDirection.HORIZONTAL,
all controls will be placed in a single row if possible.
If the controls cannot fit in a single row, they are split
into two columns. If that does not work, then use
a single column. If direction is
FormItemDirection.VERTICAL, the controls are
placed in a single column (like VBox).
A FormItem contains two areas: the label area and the controls area. The size of the label is the same regardless of the direction of the controls. The size of the control area depends on how many rows and columns are used.
The width of the label area is determined by the
labelWidth style property.
If this property is undefined (which is the default),
the width of the largest label in the parent Form container
is used.
If all children are on a single row, the width of the
control area is the sum of the widths of all the children
plus horizontalGap space between the children.
If the children are on a single column, the width of the control area is the width of the widest child.
If the children are on multiple rows and columns,
the width of the widest child is the column width,
and the width of the control area is the column width
multiplied by the number of columns plus the
horizontalGap space between each column.
measuredWidth is set to the
width of the label area plus the width of the control area
plus the value of the indicatorGap style property.
The values of the paddingLeft and
paddingRight style properties
and the width of the border are also added.
measuredHeight is set to the
sum of the preferred heights of all rows of children,
plus verticalGap space between each child.
The paddingTop and paddingBottom
style properties and the height of the border are also added.
measuredMinWidth is set to the width of the

plus the value of the indicatorGap style property.
The values of the paddingLeft and
paddingRight style properties
and the width of the border are also added.
measuredMinHeight is set to the

plus verticalGap space between each child.

updateDisplayList | () | método |
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |

Responds to size changes by setting the positions and sizes
of this container's children.
See the UIComponent.updateDisplayList() method
for more information about the updateDisplayList() method.
See the FormItem.measure() method for more
information on how the FormItem controls are positioned.
The label is aligned in the label area according to the textAlign style property.
All labels in a form are aligned with each other.
If the required property is true,
a symbol indicating the field is required is placed between
the label and the controls.
The controls are positioned in columns, as described in the
documentation for the measure() method.
The horizontalAlign style property
determines where the controls are placed horizontally.
When the direction property is
"vertical", any child that has no width
specified uses the measuredWidth rounded up
to the nearest 1/4 width of the control area.
This is done to avoid jagged right edges of controls.
This method calls the super.updateDisplayList()
method before doing anything else.
