The following Flex properties have values that are EdgeMetrics objects:
- The
borderMetricsproperty of the mx.core.Container and mx.skins.Border classes includes only the border in the calculations of the property values of the EdgeMetrics object. - The
viewMetricsproperty of the mx.core.Container class, and of subclasses of the Container class, includes possible scrollbars and non-content elements -- such as a Panel container's header area and the area for a ControlBar component -- in the calculations of the property values of the EdgeMetrics object. - The
viewMetricsAndPaddingproperty of the mx.core.Container class includes the items listed for theviewMetricsproperty, plus the any areas defined by the margins of the container in the calculations of the property values of the EdgeMetrics object.
These three properites all return a reference to the same
EdgeMetrics object that the Container is using for its measurement
and layout; they do not return a copy of this object.
If you need a copy, call the clone() method.
