getNextLeaf | () | method |
public function getNextLeaf(limitElement:FlowGroupElement = null):FlowLeafElement
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns the next FlowLeafElement object.
Parameters
limitElement:FlowGroupElement (default = null ) — Specifies FlowGroupElement on whose last leaf to stop looking. A value of null (default)
means search till no more elements.
|
FlowLeafElement — next FlowLeafElement or null if at the end
|
Example ( How to use this example )
This example creates three paragraphs, each with three SpanElement
objects. The example finds the first FlowLeafElement object
and calls
getNextLeaf()
to iterate forward through each leaf
element and trace its text, up to and including paragraph p2.

getPreviousLeaf | () | method |
public function getPreviousLeaf(limitElement:FlowGroupElement = null):FlowLeafElement
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns the previous FlowLeafElement object.

Example ( How to use this example )
This example creates three paragraphs, each with three SpanElement
objects. The example finds the last FlowLeafElement object,
and calls
getPreviousLeaf()
to iterate backward through each
leaf element and trace its text, through the limit element, paragraph p3.
