| 36 | /** | ||
| 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. | ||
