// Using a DockLayout requires the DockLayout module.
// ``` JavaScript

// ### Declaring a DockLayout.
//``` XML
//<Page>
//  <DockLayout stretchLastChild="true" >
//    <Button dock="left" text="left" style="background-color: red; margin: 5;"/ >/ >
//    <Button dock="top" text="top" style="background-color: lightblue; margin: 5;"/ >
//    <Button dock="right" text="right" style="background-color: lightgreen; margin: 5;"/ >
//    <Button dock="bottom" text="bottom" style="background-color: lightpink; margin: 5;"/ >
//    <Button text="fill" style="background-color: wheat; margin: 5;"/ >
//  </DockLayout >
