[news.eclipse.platform.swt] Re: How to dermine if Shift Key is down?

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

I'm assuming that you mean the user is holding Shift while selecting the
menu item:

public static void main(String[] args) {
    Display display = new Display();
    Shell shell = new Shell (display);
    shell.setBounds(10,10,200,200);
    Menu menu = new Menu(shell, SWT.POP_UP);
    shell.setMenu(menu);
    MenuItem item = new MenuItem(menu, SWT.NONE);
    item.setText("item");
    item.addListener(SWT.Selection, new Listener (){
        public void handleEvent(Event event) {
            System.out.print("item selected with modifiers: ");
            if ((event.stateMask & SWT.SHIFT) != 0) System.out.print("Shift
");
            if ((event.stateMask & SWT.CTRL) != 0) System.out.print("Ctrl
");
            if ((event.stateMask & SWT.ALT) != 0) System.out.print("Alt");
            System.out.println();
        }
    });
    shell.open();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) display.sleep();
    }
    display.dispose();
}
