StyledDocument
수색…
통사론
- doc.insertString (index, text, attributes); // 속성은 AttributeSet가 아니면 안된다.
DefaultStyledDocument 만들기
try {
StyledDocument doc = new DefaultStyledDocument();
doc.insertString(0, "This is the beginning text", null);
doc.insertString(doc.getLength(), "\nInserting new line at end of doc", null);
MutableAttributeSet attrs = new SimpleAttributeSet();
StyleConstants.setBold(attrs, true);
doc.insertString(5, "This is bold text after 'this'", attrs);
} catch (BadLocationException ex) {
//handle error
}
DefaultStyledDocuments는 아마도 가장 많이 사용되는 리소스가 될 것입니다. 그것들은 직접 생성 될 수 있고, StyledDocument
추상 클래스를 서브 클래스화할 수 있습니다.
JTextPane에 StyledDocument 추가하기
try {
JTextPane pane = new JTextPane();
StyledDocument doc = new DefaultStyledDocument();
doc.insertString(0, "Some text", null);
pane.setDocument(doc); //Technically takes any subclass of Document
} catch (BadLocationException ex) {
//handle error
}
그런 다음 JTextPane을 모든 Swing GUI 양식에 추가 할 수 있습니다.
DefaultStyledDocument 복사하기
StyledDocuments
일반적으로 복제를 구현하지 않으므로 필요한 경우 다른 방법으로 복사해야합니다.
try {
//Initialization
DefaultStyledDocument sourceDoc = new DefaultStyledDocument();
DefaultStyledDocument destDoc = new DefaultStyledDocument();
MutableAttributeSet bold = new SimpleAttributeSet();
StyleConstants.setBold(bold, true);
MutableAttributeSet italic = new SimpleAttributeSet();
StyleConstants.setItalic(italic, true);
sourceDoc.insertString(0, "Some bold text. ", bold);
sourceDoc.insertString(sourceDoc.getLength(), "Some italic text", italic);
//This does the actual copying
String text = sourceDoc.getText(0, sourceDoc.getLength()); //This copies text, but loses formatting.
for (int i = 0; i < text.length(); i++) {
Element e = destDoc.getCharacterElement(i); //A Elment describes a particular part of a document, in this case a character
AttributeSet attr = e.getAttributes(); //Gets the attributes for the character
destDoc.insertString(destDoc.getLength(), text.substring(i, i+1), attr); //Gets the single character and sets its attributes from the element
}
} catch (BadLocationException ex) {
//handle error
}
DefaultStyledDocument를 RTF로 직렬화하기
AdvancedRTFEditorKit 라이브러리를 사용하면 DefaultStyledDocument
를 RTF 문자열로 직렬화 할 수 있습니다.
try {
DefaultStyledDocument writeDoc = new DefaultStyledDocument();
writeDoc.insertString(0, "Test string", null);
AdvancedRTFEditorKit kit = new AdvancedRTFEditorKit();
//Other writers, such as a FileWriter, may be used
//OutputStreams are also an option
Writer writer = new StringWriter();
//You can write just a portion of the document by modifying the start
//and end indexes
kit.write(writer, writeDoc, 0, writeDoc.getLength());
//This is the RTF String
String rtfDoc = writer.toString();
//As above this may be a different kind of reader or an InputStream
StringReader reader = new StringReader(rtfDoc);
//AdvancedRTFDocument extends DefaultStyledDocument and can generally
//be used wherever DefaultStyledDocument can be.
//However for reading, AdvancedRTFDocument must be used
DefaultStyledDocument readDoc = new AdvancedRTFDocument();
//You can insert at different values by changing the "0"
kit.read(reader, readDoc, 0);
//readDoc is now the same as writeDoc
} catch (BadLocationException | IOException ex) {
//Handle exception
ex.printStackTrace();
}
