Focus is always in exactly one place, so if it's in a Text within a Shell
then the Shell is not the focus control.  It's common to say the shell has
focus relative to other shells, but technically it's active, not focused.
The snippet:

public static void main(String[] args) {
    final Display display = new Display();
    final Shell shell = new Shell(display);
    shell.setBounds(10,10,200,200);
    final Text text1 = new Text(shell, SWT.SINGLE);
    text1.setBounds(10,10,100,30);
    final Text text2 = new Text(shell, SWT.SINGLE);
    text2.setBounds(10,50,100,30);
    Listener listener = new Listener() {
        public void handleEvent(Event event) {
            System.out.println("-------");
            System.out.println("text1 isFocusControl: " +
text1.isFocusControl());
            System.out.println("text2 isFocusControl: " +
text2.isFocusControl());
            System.out.println("shell isFocusControl: " +
shell.isFocusControl());
        }
    };
    display.addFilter(SWT.FocusIn, listener);
    shell.open();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) display.sleep();
    }
    display.dispose();
}
