widgetSelected() and different OS platform behaviors

问题

I have this Java code where I implement a selectionListener. While it works great on Windows, surprisingly, it doesn't work on Linux (Debian 9.9, Cinnamon) and when I debug, the println code is never reached. Any idea why it would work on one platform (Win?) but not on another (Linux) ?

        DateTime dt = new DateTime(container, SWT.TIME | SWT.MEDIUM | SWT.BORDER);
        FormToolkit tk =new FormToolkit(parent.getDisplay());
        tk.adapt(dt, true, false);
        dt.addSelectionListener(new SelectionAdapter() {
                    @Override
                    public void widgetSelected(final SelectionEvent e) {
                           System.out.println("Event caught!");
}
