如何从的JTextPane获取样式？ [英] How to get style from JtextPane?

问题描述

我有格式的文本JTextPane中。我需要复制完整的风格和属性
从这个文本传输到其他的JTextPane。有一个例子或code片段
看看它是如何工作的？

I have a JtextPane with formatted text. I need to copy the complete style and attributes from this text to transfer it to another JtextPane. Is there an example or code snippet to see how it works?

好吧，这里是一个code，我发现，我已经改变了一点点：

ok, here is a code I found and I've changed a little bit:

import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;

public class Main  {

private JTextPane textPane1;
private JTextPane textPane2;
private Document doc1;
private Document doc2;
private JFrame frame1;
private JFrame frame2;

private MutableAttributeSet black;    
private MutableAttributeSet red;
private AttributeSet attribute;    

public Main() {
    textPane1 = new JTextPane();

    black = new SimpleAttributeSet();
    red = new SimpleAttributeSet();
    StyleConstants.setForeground(black, Color.black);
    StyleConstants.setForeground(red, Color.red);
    textPane1.setEditorKit(new StyledEditorKit());                    
    doc1 = textPane1.getDocument();       

    append1("This is a Test!\n");

    //set color = red
    attribute = red;
    append1("Hello world! Hello Stackoverflow\n");        

    //set color = black
    attribute = black;
    append1("the text is black again\n");     

    StyledDocument styledDocument = textPane1.getStyledDocument();

    textPane2 = new JTextPane();
    textPane2.setEditorKit(new StyledEditorKit());
    doc2 = textPane2.getDocument();
    String text = textPane1.getText();
    append2(text);

    //transfer format data of text in frame1 to frame2
    int docLength = doc1.getLength();
    Element element;        
    AttributeSet attribSet;
    for(int i=0;i<docLength;i++) {            
        element = styledDocument.getCharacterElement(i);            
        attribSet = element.getAttributes();            
        StyleConstants.setForeground(red, Color.red);
    }

    createFrames();        
}

private void append1(String text){
    try {
        doc1.insertString(doc1.getLength(), text, attribute);
    } catch (BadLocationException ex) {
        ex.printStackTrace();
    }
}

private void append2(String text) {
    try {
        doc2.insertString(doc2.getLength(), text, attribute);
    } catch (BadLocationException ex) {
        ex.printStackTrace();
    }
}

private void createFrames() {
    frame1 = new JFrame("frame 1");     
    frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame1.setSize(400, 300);
    frame1.setLocationRelativeTo(null);
    frame1.getContentPane().add(new JScrollPane(textPane1), BorderLayout.CENTER);
    frame1.setVisible(true);

    frame2 = new JFrame("frame 2");
    frame2.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame2.setSize(400, 300);
    frame2.setLocation(300,0);
    frame2.getContentPane().add(new JScrollPane(textPane2), BorderLayout.CENTER);
    frame2.setVisible(true);
}

public static void main(String args[]) {
    new Main();     
}
}

我也想传输格式样式和属性第二帧。

I also want to transfer format styles and attributes to the second frame.

我已经解决了。

结果
    进口的java.awt。*;

import java.awt.*;

import javax.swing.*;
import javax.swing.text.*;

public class Main  {

private JTextPane textPane1;
private JTextPane textPane2;
private Document doc1;
private Document doc2;
private JFrame frame1;
private JFrame frame2;

private MutableAttributeSet black;    
private MutableAttributeSet red;
private AttributeSet attribute;    

public Main() throws BadLocationException {
    textPane1 = new JTextPane();

    black = new SimpleAttributeSet();
    red = new SimpleAttributeSet();
    StyleConstants.setForeground(black, Color.black);
    StyleConstants.setForeground(red, Color.red);
    textPane1.setEditorKit(new StyledEditorKit());                    
    doc1 = textPane1.getDocument();       

    append1("This is a Test!\n");

    //set color = red
    attribute = red;
    append1("Hello world! Hello Stackoverflow\n");        

    //set color = black
    attribute = black;
    append1("the text is black again\n");     


    //IMPORTANT PART: attribute of each character from the styled text will 
    //be transfered to the second textpanel
    StyledDocument styledDocument = textPane1.getStyledDocument();   
    Element element; 

    textPane2 = new JTextPane();
    textPane2.setEditorKit(new StyledEditorKit());

    doc2 = textPane2.getDocument(); 
    for(int i=0; i<styledDocument.getLength();i++) {
        element = styledDocument.getCharacterElement(i);
        AttributeSet attributeNew = element.getAttributes();   
        System.out.println(i);
        append2(styledDocument.getText(i, 1), attributeNew);    
    }

    createFrames();        
}

private void append1(String text){
    try {
        doc1.insertString(doc1.getLength(), text, attribute);
    } catch (BadLocationException ex) {
        ex.printStackTrace();
    }
}

private void append2(String text, AttributeSet attributeNew) {

    } catch (BadLocationException ex) {

    }
}

    frame1 = new JFrame("frame 1");     
    frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame1.setSize(400, 300);

    frame2.setSize(400, 300);
    frame2.setLocation(300,0);
    frame2.getContentPane().add(new JScrollPane(textPane2), BorderLayout.CENTER);

}

public static void main(String args[]) throws BadLocationException {
