SWING
Java pone a disposición del programador el paquete javax.swing para crear unas interfaces gráficas. En este capítulo veremos para qué la Sun Microsystem ha creado otro paquete y qué diferencias hay con awt.
Para presentar el paquete hablaré del programa que estoy preparando para mi tesina en la Facultad de Informática de la Universidad de Pisa. Para informaciones con respecto a Orespics podéis poneros en contacto conmigo o con las profesoras Laganà y Ricci del Departamento de Informática de Pisa (Corso Italia, 40).
El nombre del programa es Orespics Programming Language y, en práctica, es un ambiente integrado en el que es posible programar agentes paralelos que comunicam entre ellos, intercambiando mensajes. El ambiente permite definir y poner en marcha estos agentes. Se propone como instrumento de soporte didáctico al aprendizaje de las modalidades de programación paralela, programación que puede resultar muy difícil.
Precisamente por ser un instrumento didáctico, tiene una interfaz usuario User Friendly. La interfaz ha sido escrita utilizando el paquete Swing de Java.
Swing ha sido totalmente escrito en Java utilizando el paquete awt, y pone a disposición del usuario muchas clases que están también en awt, pero mucho mejores y más potentes. Además introduce muchas más clases que no están en awt.
Por lo tanto, veamos cuáles son las clases y las interfaces incluidas en el paquete:

AWT
AWT es el acrónimo del X Window Toolkit para Java, donde X puede ser cualquier cosa: Abstract, Alternative, Awkward, Another o Asqueroso; aunque parece que Sun se decanta por Abstracto, seriedad por encima de todo. Se trata de una biblioteca de clases Java para el desarrollo de Interfaces de Usuario Gráficas. La versión del AWT que Sun proporciona con el JDK se desarrolló en sólo dos meses y es la parte más débil de todo lo que representa Java como lenguaje. El entorno que ofrece es demasiado simple, no se han tenido en cuenta las ideas de entornos gráficos novedosos, sino que se ha ahondado en estructuras orientadas a eventos, llenas de callbacks y sin soporte alguno del entorno para la construcción gráfica; veremos que la simple acción de colocar un dibujo sobre un botón se vuelve una tarea harto complicada. Quizá la presión de tener que lanzar algo al mercado haya tenido mucho que ver en la pobreza de AWT.
JavaSoft, asegura que esto sólo era el principio y que AWT será multi-idioma, tendrá herramientas visuales, etc. En fin, al igual que dicen los astrólogos, el futuro nos deparará muchas sorpresas.
La estructura básica del AWT se basa en Componentes y Contenedores. Estos últimos contienen Componentes posicionados a su respecto y son Componentes a su vez, de forma que los eventos pueden tratarse tanto en Contenedores como en Componentes, corriendo por cuenta del programador (todavía no hay herramientas de composición visual) el encaje de todas las piezas, así como la seguridad de tratamiento de los eventos adecuados. Nada trivial.
No obstante y pese a ello, vamos a abordar en este momento la programación con el AWT para tener la base suficiente y poder seguir profundizando en las demás características del lenguaje Java, porque como vamos a ir presentando ejemplos gráficos es imprescindible el conocimiento del AWT. Mientras tanto, esperemos que JavaSoft sea fiel a sus predicciones y lo que ahora veamos nos sirva de base para migrar a un nuevo y maravilloso AWT.
