// # DockLayout
// Using a DockLayout requires the DockLayout module.
// ``` JavaScript
import dockModule = require("ui/layouts/dock-layout");
// ```

// ### 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 >
//</Page>
//```
// </snippet>

// Other frequently used modules when working with a DockLayout include:
// ``` JavaScript
import enums = require("ui/enums");
// ```
