Hi all,
The component below gets to instantiate its chid correctly but it
doesn't show up in the displaylist.
any clues??
package foo.conditionals
{
import mx.containers.HBox;
/**
*
* Does not support changing the condition property at runtime yet
*
* @author abucchi
*
*/
public class ConditionalContainer extends HBox
{
private var _condition:Boolean;
public function get condition():Boolean
{
return _condition;
}
public function set condition( value:Boolean ):void
{
_condition = value;
}
override public function createComponentsFromDescriptors(
recurse:Boolean = true ):void
{
if ( childDescriptors.length == 0 )
return; // no children specified
if ( condition ) // condition met, create first child
{
createComponentFromDescriptor(
childDescriptors[0] , recurse );
}
else if ( childDescriptors.length == 2 ) // not met,
create second
child if specified
{
createComponentFromDescriptor(
childDescriptors[1] , recurse );
}
}
}
}
