How to use it?

Scaladin 2 is for Vaadin 6 and Scaladin 3 for Vaadin 7. Scaladin 3 requires Scala 2.10. The JAR files and a Maven dependencies for Scaladin can be found from the Vaadin Directory.

The following listing shows what Scaladin 3 code looks like:

package com.example

import vaadin.scala._

class ScaladinExampleUI extends UI {
    content = new Button {
        caption = "Click me!"
        icon = ThemeResource("../runo/icons/16/globe.png")
        clickListeners += Notification.show("Hello World!")
    }
}

The easiest way to test Scaladin 2 is to use Risto's giter8 template that generates a sbt project:

> g8 ripla/vaadin-scala
<answer questions, enter for defaults>
> cd <project dir>
> sbt container:start ~aux-compile

After the above commands you have a working Scaladin application running on http://localhost:8080. You can even edit the generated Application class and changes are affected to the browser. In order to import your project into Eclipse, you have to say:

> sbt eclipse

That generates needed Eclipse configuration files into the project.
