Simple UI
BeanShell is a small, free, embeddable Java source interpreter with object scripting language features,
written in Java. BeanShell is a natural scripting language for Java.
This requires the library bsh-2.0b4.jar to be in classpath.
The following example shows developing simple UI in beanshell script.
// Open input popup dialog strName = JOptionPane.showInputDialog ( null, " Enter your name : " ) ; //implementing ActionListener interface (this - context reference) actionPerformed ( event ) { print ( event ) ; } //implementing WindowListener interface WindowListener listener = new WindowAdapter () { public void windowClosing ( WindowEvent w ) { System.exit ( 0 ) ; } } ; //Create button and add to frame button = new JButton ( "Click Me" ) ; button.addActionListener ( this ) ; frame = new JFrame ( "Hello " + strName ) ; frame.getContentPane () .add ( button ) ; frame.addWindowListener ( listener ) ; frame.setSize ( 200 , 200 ) ; frame.setVisible ( true ) ;
