useNativeproperty 
useNative:Boolean

Determines if the system native web browser control is used or if Adobe AIR's embedded version of the WebKit engine is used.

Note: Although it is not prohibited, with some content, failures can occur when the same process uses both the embedded and the system WebKit, so it is recommended that all StageWebViews in a given application be constructed with the same value for useNative. In addition, as HTMLLoader depends on the embedded WebKit, applications using HTMLLoader should only construct StageWebViews with useNative set to false.


Implementation
    public function get useNative():Boolean
    public function set useNative(value:Boolean):void
Constructor Detail
WebView()Constructor
public function WebView()

Constructor.

Method Detail
autoSizeIfNeeded()method
protected function autoSizeIfNeeded():Boolean

If the component's dimensions have not been set explicitly, it will measure its content and determine an ideal size for itself. If the explicitWidth or explicitHeight member variables are set, those value will be used without additional measurement. If one is set, but not the other, the dimension with the explicit value will not be measured, but the other non-explicit dimension will still need measurement.

Calls saveMeasurements() to set up the actualWidth and actualHeight member variables used for layout.

Meant for internal use, and subclasses may override this function with a custom implementation.

Returns
Boolean
