ConstraintRow

Package | mx.containers.utilityClasses
Class | public class ConstraintRow
Inheritance | ConstraintRow flash.events.EventDispatcher
Implements | IMXMLObject

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

ConstraintRow class partitions an absolutely positioned container in the horizontal plane. ConstraintRow instances have 3 sizing options: fixed, percentage, and content. These options dictate the position of the constraint row, the amount of space the constraint row takes in the container, and how the constraint row deals with a change in the size of the container.

Property Detail

baseline | property

`baseline:Object`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Number that specifies the baseline of the ConstraintRow instance, in pixels, either relative to the top edge of the row or to the max ascent of the elements contained in this row.

The default value is `"maxAscent:0"`.

This property can be used as the source for data binding.

Implementation
`public function get baseline():Object`
`public function set baseline(value:Object):void`

explicitHeight | property |

`explicitHeight:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Number that specifies the explicit height of the ConstraintRow instance, in pixels, in the ConstraintRow instance's coordinates.

This property can be used as the source for data binding.

Implementation
`public function get explicitHeight():Number`
`public function set explicitHeight(value:Number):void`

height | property |

`height:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Number that specifies the height of the ConstraintRow instance, in pixels, in the parent's coordinates.

This property can be used as the source for data binding.

Implementation
`public function get height():Number`
`public function set height(value:Number):void`

id | property |

`id:String`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

ID of the ConstraintRow instance. This value becomes the instance name of the constraint row and should not contain white space or special characters.

Implementation
`public function get id():String`
`public function set id(value:String):void`

maxHeight | property |

`maxHeight:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Number that specifies the maximum height of the ConstraintRow instance, in pixels, in the ConstraintRow instance's coordinates.

This property can be used as the source for data binding.

Implementation
`public function get maxHeight():Number`
`public function set maxHeight(value:Number):void`

minHeight | property |

`minHeight:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Number that specifies the minimum height of the ConstraintRow instance, in pixels, in the ConstraintRow instance's coordinates.

This property can be used as the source for data binding.

Implementation
`public function get minHeight():Number`
`public function set minHeight(value:Number):void`

percentHeight | property |

`percentHeight:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Number that specifies the height of a component as a percentage of its parent's size. Allowed values are 0-100. The default value is NaN. Setting the `width` property resets this property to NaN.

This property can be used as the source for data binding.

Implementation
`public function get percentHeight():Number`
`public function set percentHeight(value:Number):void`

ConstraintRow | () | Constructor

`public function ConstraintRow()`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Constructor.

Method Detail

initialized | () | method

`public function initialized(document:Object, id:String):void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Called automatically by the MXML compiler when the ConstraintRow instance is created using an MXML tag. If you create the constraint row through ActionScript, you must call this method passing in the MXML document and `null` for the `id`.

Parameters

| `document:Object` — The MXML document containing this ConstraintRow.
| `id:String` — Ignored.

setActualHeight | () | method |

`public function setActualHeight(h:Number):void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Sizes the ConstraintRow

Parameters

| `h:Number` — Height of constaint row computed during parent container processing.
