By default components added to a JToolBar will be left aligned. Often we want to shift some item to the right (for example a Help button is often displayed to the right).
The JToolBar uses a BoxLayout to layout it’s components. This allows us to simply add some ‘glue’ to push subsequently added components to the right.
JToolBar toolbar = new JToolBar();
// These buttons will be left aligned by default
toolbar.add(new JButton("Open"));
toolbar.add(new JButton("Save"));
// add some glue so subsequent items are pushed to the right
toolbar.add(Box.createHorizontalGlue());
// This Help button will be right aligned
toolbar.add(new JButton("Help"));
