/**
* 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.
