/**
 * A text field with a find icon in which the user enters text that identifies
 * items to search for.
 * 
 * JXSearchField almost looks and behaves like a native Windows Vista search
 * box, a Mac OS X search field, or a search field like the one used in Mozilla
 * Thunderbird 2.0 - depending on the current look and feel.
 * 
 * JXSearchField is a text field that contains a find button and a cancel
 * button. The find button normally displays a lens icon appropriate for the
 * current look and feel. The cancel button is used to clear the text and
 * therefore only visible when text is present. It normally displays a 'x' like
 * icon. Text can also be cleared, using the 'Esc' key.
 * 
 * The position of the find and cancel buttons can be customized by either
 * changing the search fields (text) margin or button margin, or by changing the
 * {@link LayoutStyle}.
 * 
 * JXSearchField supports two different search modes: {@link SearchMode#INSTANT}
 * and {@link SearchMode#REGULAR}.
 * 
 * A search can be performed by registering an {@link ActionListener}. The
 * {@link ActionEvent}s command property contains the text to search for. The
 * search should be cancelled, when the command text is empty or null.
