Create a Constrained Layout

Make the components on the page change with the form. The Layout mode of all containers should be set to absolute mode (absolute ).

Demo:

<? XML version = "1.0" encoding = "UTF-8"?>
<Mx: Application xmlns: MX = "http://www.adobe.com/2006/mxml" layout = "absolute">
<! -- Use X, Y to define the position of the component;
Use width, height to define the size of the component;
Use left, right, top, bottom to define the distance between the component border and
The container border;
-->
<Mx: Label x = "20" Y = "60" text = "email"/>
<Mx: textinput y = "60" Right = "60" Left = "90"/>
<Mx: Label x = "20" Y = "90" text = "Comments"/>
<Mx: textarea left = "90" Right = "60" Top = "90" bottom= "190"/>
<Mx: button label = "send" Right = "60" Bottom = "150"/>

</MX: Application>
