property to false, some components still respond to mouse interactions such
as mouseOver. As a result, to fully disable UIComponents,
you should also set the value of the mouseEnabled property to false.
If you set the enabled property to false
for a container, Flex dims the color of the container and of all

owner | property |
owner:DisplayObjectContainer| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The owner of this IVisualElement object. By default, it is the parent of this IVisualElement object. However, if this IVisualElement object is a child component that is popped up by its parent, such as the drop-down list of a ComboBox control, the owner is the component that popped up this IVisualElement object.
This property is not managed by Flex, but by each component.
Therefore, if you use the PopUpManger.createPopUp() or
PopUpManger.addPopUp() method to pop up a child component,
you should set the owner property of the child component
to the component that popped it up.
The default value is the value of the parent property.
