// FESI examples - JM Lugrin - 1998
//
// This example demonstrates how you can play with the swing 
// toolkit with the FESI EcmaScript interpreter.

// Requires: JavaAccess, Swing-1.0
//           Adapt swingev.bat to run this example


// First define some shortcuts - note that partially expanded
// package names can be assigned. 

Swing = Packages.javax.swing; // Just change this line if it moves

JFrame = Swing.JFrame;
JButton = Swing.JButton;
JRadioButton = Swing.JRadioButton;
ButtonGroup = Swing.ButtonGroup;
JPanel = Swing.JPanel;
UIManager = Swing.UIManager;
SwingUtilities = Swing.SwingUtilities;

// As there is no exception handling in EcmaScript, there
// will be an error if the look and feel is not on the classpath
cplfClassName = UIManager.getCrossPlatformLookAndFeelClassName();
slfClassName = UIManager.getSystemLookAndFeelClassName();


// Create the panel and its content 
panel = new JPanel();
button = new JButton("Hello, world");
button.setToolTipText("This is a Button with Text");
button.setMnemonic('h'); //for looks only; button does nada

cplfButton = new JRadioButton("Cross Platform");
cplfButton.setMnemonic('c');  // String of length 1 are considered as char 
slfButton = new JRadioButton("System");
slfButton.setMnemonic('s'); 
	
// Group the radio buttons.
group = new ButtonGroup();
group.add(cplfButton);
group.add(slfButton);

panel.add(button);
panel.add(cplfButton);
panel.add(slfButton);


// Now create the frame
frame = new JFrame("Show swing");
frame.getContentPane().add("Center", panel);
frame.pack();
frame.setVisible(true);
frame.onWindowClosing = "frame.dispose();exit();";

cplfButton.onAction = "setLF(cplfClassName);";
slfButton.onAction = "setLF(slfClassName);";

function setLF(lf) {
    UIManager.setLookAndFeel(lf);
	SwingUtilities.updateComponentTreeUI(frame);
	frame.pack();
