public class WindowEvent

extends TypedEvent

A WindowEvent is sent by a Browser when a new window needs to be created or when an existing window needs to be closed. This notification occurs when a javascript command such as window.open or window.close gets executed by a Browser.

The following example shows how WindowEvent's are typically handled.

    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);
        shell.setText("Main Window");
        shell.setLayout(new FillLayout());
        Browser browser = new Browser(shell, SWT.NONE);
        initialize(display, browser);
        shell.open();
        browser.setUrl("http://www.eclipse.org");
        while (!shell.isDisposed()) {
            if (!display.readAndDispatch())
                display.sleep();
        }
        display.dispose();
    }

    static void initialize(final Display display, Browser browser) {
        browser.addOpenWindowListener(new OpenWindowListener() {
            public void open(WindowEvent event) {
                Shell shell = new Shell(display);
                shell.setText("New Window");
                shell.setLayout(new FillLayout());
                Browser browser = new Browser(shell, SWT.NONE);
                initialize(display, browser);
                event.browser = browser;
            }
        });
        browser.addVisibilityWindowListener(new VisibilityWindowListener() {
            public void hide(WindowEvent event) {
                Browser browser = (Browser)event.widget;
                Shell shell = browser.getShell();
                shell.setVisible(false);
            }
            public void show(WindowEvent event) {
                Browser browser = (Browser)event.widget;
                Shell shell = browser.getShell();
                if (event.location != null) shell.setLocation(event.location);
                if (event.size != null) {
                    Point size = event.size;
                    shell.setSize(shell.computeSize(size.x, size.y));
                }
                shell.open();
            }
        });
        browser.addCloseWindowListener(new CloseWindowListener() {
            public void close(WindowEvent event) {
                Browser browser = (Browser)event.widget;
                Shell shell = browser.getShell();
                shell.close();
            }
        });
    }
