Does

no automatic layout, and requires you to explicitly

define the location of each child component

If the Application component’s layout property is absolute,

each child component must have an x and y coordinate de-

fined; otherwise, the component will be displayed in the (0,0)

position.

The Application container can also be formatted using any of

the several style parameters that are available, including back

groundGradientColors and verticalGap. In Example 4-1, the

Application tag is used to lay out the child controls.

Example 4-1. The Application MXML

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

backgroundGradientColors="[#FFFFFF, #FFDE00]" verticalGap="15"

layout="horizontal">

<mx:Image source="assets/animals03.jpg" />

<mx:Label text="Photographed by Elsie Weil" fontSize="15"

fontWeight="bold" />

</mx:Application>

Figure 4-1 shows the result of this code.
