replaceChildren | () | method |
public function replaceChildren(beginChildIndex:int, endChildIndex:int, ... rest):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Replaces child elements in the group with the specified new elements. Use the beginChildIndex and
endChildIndex parameters to govern the operation as follows:
- To delete elements, do not pass any replacement elements.
- To insert elements, pass the same value for
beginChildIndexandendChildIndex. The new elements is inserted before the specified index. - To append elements, pass
numChildrenforbeginChildIndexandendChildIndex.
Otherwise, this method replaces the specified elements, starting with the element at beginChildIndex
and up to but not including endChildIndex.
Parameters
beginChildIndex:int — The index value for the start position of the replacement range in the children array.
| |
endChildIndex:int — The index value following the end position of the replacement range in the children array.
| |
... rest — The elements to replace the specified range of elements. Can be a sequence containing flow elements or
arrays or vectors thereof.
|
Throws
RangeError — The beginChildIndex or endChildIndex specified is out of range.
|
Example ( How to use this example )
This example replaces the three spans in the second paragraph with two
new ones.

splitAtIndex | () | method |
public function splitAtIndex(childIndex:int):FlowGroupElement| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Splits this object at the position specified by the childIndex parameter. If this group element has
a parent, creates a shallow copy of this object and replaces its children with the elements up to the index. Moves
elements following childIndex into the copy.
Parameters
childIndex:int |
FlowGroupElement — the new FlowGroupElement object.
|
Throws
RangeError — if childIndex is greater than the length of the children.
