<mx:Application>
tag, the first tag in an MXML application file.
While you might find it convenient to use the Application container
as the only container in your application, in most cases you explicitly
define at least one more container before you add any controls
to your application.
Applications support a predefined plain style that sets a white background, left alignment, and removes all margins. To use this style, do the following:
<mx:Application styleName="plain" />
This is equivalent to setting the following style attributes:
backgroundColor="0xFFFFFF"
horizontalAlign="left"
paddingLeft="0"
paddingTop="0"
paddingBottom="0"
paddingRight="0"
MXML Syntax
Hide MXML Syntax
The <mx:Application> tag inherits all of the tag
attributes of its superclass and adds the following tag attributes:
