/**

|
|
37 |
* This is the set of things needed by a text component
|
|
|
38 |
* to be a reasonably functioning editor for some <em>type</em>
|
|
|
39 |
* of text document. This implementation provides a default
|
|
|
40 |
* implementation which treats text as plain text and
|
|
|
41 |
* provides a minimal set of actions for a simple editor.
|
|
|
42 |
* <p>
|
|
|
43 |
* <dl>
|
|
|
44 |
* <dt><b><font size=+1>Newlines</font></b>
|
|
|
45 |
* <dd>
|
|
|
46 |
* There are two properties which deal with newlines. The
|
|
|
47 |
* system property, <code>line.separator</code>, is defined to be
|
|
|
48 |
* platform-dependent, either "\n", "\r", or "\r\n". There is also
|
|
|
49 |
* a property defined in <code>DefaultEditorKit</code>, called
|
|
|
50 |
* <a href=#EndOfLineStringProperty><code>EndOfLineStringProperty</code></a>,
|
|
|
51 |
* which is defined automatically when a document is loaded, to be
|
|
|
52 |
* the first occurrence of any of the newline characters.
|
|
|
53 |
* When a document is loaded, <code>EndOfLineStringProperty</code>
|
|
|
54 |
* is set appropriately, and when the document is written back out, the
|
|
|
55 |
* <code>EndOfLineStringProperty</code> is used. But while the document
|
|
|
56 |
* is in memory, the "\n" character is used to define a
|
|
|
57 |
* newline, regardless of how the newline is defined when
|
|
|
58 |
* the document is on disk. Therefore, for searching purposes,
|
|
|
59 |
* "\n" should always be used. When a new document is created,
|
|
|
60 |
* and the <code>EndOfLineStringProperty</code> has not been defined,
|
|
|
61 |
* it will use the System property when writing out the
|
|
|
62 |
* document.
|
|
|
63 |
* <p>Note that <code>EndOfLineStringProperty</code> is set
|
|
|
64 |
* on the <code>Document</code> using the <code>get/putProperty</code>
|
|
|
65 |
* methods. Subclasses may override this behavior.
