#fxml

JavaFX — платформа на основе Java для создания приложений с насыщенным графическим интерфейсом. Может использоваться как для создания настольных приложений, запускаемых непосредственно из-под операционных систем, так и для интернет-приложений (RIA), работающих в браузерах, и для приложений на мобильных устройствах. JavaFX призвана заменить использовавшуюся ранее библиотеку Swing.

Der Aufruf ist denkbar einfach. Er könnte z.B. wie folgt aussehen:

WPF is the name for a bunch of libraries providing a way to create rich client applications. WPF includes XAML. I've been looking for a Java equivalent to what .NET offers with WPF. For those who are unfamiliar, the idea behind it is that you define your UI in a domain-specific language (DSL) to keep the UI separated from your actual code. This has a ton of benefits including speedier development and easier maintainability. This is not valid syntax but it may look like this:

// UI - XAML or some other DSL <ListBox binding="myListVariable"></ListBox> <Button content="Add Order"></Button>

// Code for the UI List<String> myListVariable = new ArrayList(); myListVariable.add("Printer"); myListVariable.add("Keyboard");

Essentially, the UI will keep the ListBox updated with the contents of the myListVariable variable. If you add something to the myListVariable later on, the UI will automatically update. That is the power of data-binding.

I finally found a good equivalent of WPF for Java called JavaFX. It's been around forever but has not had a good equivalent to XAML until relatively recently which is called FXML. My quick research tells me that FXML came out around 2011. However, it did not get bidirectional data binding until about April of 2012. An example pulled from http://docs.oracle.com/javafx/2/api/javafx/fxml/doc-files/introduction_to_fxml.html#expression_binding looks like this:

<TextField fx:id="textField"/> <Label text="${textField.text}"/>

Oracle today announced the general availability of NetBeans Integrated Development Environment (IDE) 7.3.

NetBeans IDE 7.3 features advanced HTML5, JavaScript and CSS development capabilities, for faster and easier rich Web and mobile application development.

Dois Guias relacionados a construção de interfaces usando o javaFX, sempre lembrando que o javaFX agora na versão 2 se transformou em uma API a parte para a construção de interfaces e animações interagindo perfeitamente com código Java "normal". 

O primeiro guia é o do JavaFX Scene Builder que é uma ferramenta para a construção de interfaces no estilo WYSIWYG ( What you see is what you get).

O segundo guia é sobre o FXML, uma linguagem de marcação tipo XML utilizada no Scence Buider , para cada interface o aplicativo gera um arquivo FXML que é ligado dinamicamente no carregador da interface e dispensa a compilação do código, ou seja você pode alterar a interface sem precisar compilar novamente o código

Guia de uso da ferramenta para construção de Rich Interfaces utilizando javaFX. A ferramenta gera a interface descrita em um arquivo FXML que é uma linguagem baseada em XML, a partir dai o programador conecta as classes de negocio na interface .

Confira o guia do Scence Builder em:

O Guia também pode ser baixado em formato PDF.

Já o guia do FXML você pode encontra no endereço:
