37 * A {@code TextField} object is a text component
38 * that allows for the editing of a single line of text.
39 * If input text contains new line character, then
40 * {@code TextField} replaces it by space character.
41 * <p>
42 * For example, the following image depicts a frame with four
43 * text fields of varying widths. Two of these text fields
44 * display the predefined text {@code "Hello"}.
45 * <p>
46 * <img src="doc-files/TextField-1.gif" alt="The preceding text describes this image."
47 * style="float:center; margin: 7px 10px;">
48 * <p>
49 * Here is the code that produces these four text fields:
50 *
51 * <hr><blockquote><pre>
52 * TextField tf1, tf2, tf3, tf4;
53 * // a blank text field
54 * tf1 = new TextField();
55 * // blank field of 20 columns
56 * tf2 = new TextField("", 20);
57 * // predefined text displayed
58 * tf3 = new TextField("Hello!");
59 * // predefined text in 30 columns
60 * tf4 = new TextField("Hello", 30);
61 * </pre></blockquote><hr>
62 * <p>
63 * Every time the user types a key in the text field, one or
64 * more key events are sent to the text field. A {@code KeyEvent}
65 * may be one of three types: keyPressed, keyReleased, or keyTyped.
66 * The properties of a key event indicate which of these types
67 * it is, as well as additional information about the event,
68 * such as what modifiers are applied to the key event and the
69 * time at which the event occurred.
70 * <p>
71 * The key event is passed to every {@code KeyListener}
72 * or {@code KeyAdapter} object which registered to receive such
73 * events using the component's {@code addKeyListener} method.
74 * ({@code KeyAdapter} objects implement the
75 * {@code KeyListener} interface.)
76 * <p>
77 * It is also possible to fire an {@code ActionEvent}.
78 * If action events are enabled for the text field, they may
79 * be fired by pressing the {@code Return} key.
80 * <p>
81 * The {@code TextField} class's {@code processEvent}
82 * method examines the action event and passes it along to
83 * {@code processActionEvent}. The latter method redirects the
84 * event to any {@code ActionListener} objects that have
85 * registered to receive action events generated by this
86 * text field.
