}
在写个main方法测试下就行了
	public static void main(String[] args) {
		Display display = new Display();
		final Shell shell = new Shell(display);
		shell.setLayout(new FillLayout());

		Button open = new Button(shell, SWT.PUSH);
		open.setText(" Open Dialog ");
		open.addSelectionListener(new SelectionAdapter() {
			public void widgetSelected(SelectionEvent e) {
				final TimePicker dialog = new TimePicker();
				
				
				dialog.open();
			}
		});
		shell.pack();
		shell.open();

		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		display.dispose();
