How to extract the word and line wrapping information from JTextArea for text with given font
- by Gábor Lipták
I have to convert styled text to wrapped simple text (for SVG word wrapping). I cannot beleive that the word wrapping information (how many lines are there, where are the line breaks) cannot be extracted from the JTextArea. So I created a small frame program:
package bla;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Font;
import java.awt.Frame;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.util.ArrayList;
import java.util.List;
import javax.swing.JTextArea;
public class Example1 extends WindowAdapter {
private static String content = "01234567890123456789\n" + "0123456 0123456 01234567 01234567";
JTextArea text;
public Example1() {
Frame f = new Frame("TextArea Example");
f.setLayout(new BorderLayout());
Font font = new Font("Serif", Font.ITALIC, 20);
text = new JTextArea();
text.setFont(font);
text.setForeground(Color.blue);
text.setLineWrap(true);
text.setWrapStyleWord(true);
f.add(text, BorderLayout.CENTER);
text.setText(content);
// Listen for the user to click the frame's close box
f.addWindowListener(this);
f.setSize(100, 511);
f.show();
}
public static List<String> getLines( JTextArea text ) {
//WHAT SHOULD I WRITE HERE
return new ArrayList<String>();
}
public void windowClosing(WindowEvent evt) {
List<String> lines = getLines(text);
System.out.println( "Number of lines:" + lines.size());
for (String line : lines) {
System.out.println( line );
}
System.exit(0);
}
public static void main(String[] args) {
Example1 instance = new Example1();
}
}
If you run it you will see this:
And what I expect as output:
Number of lines:6
0123456789
0123456789
0123456
0123456
01234567
01234567
What should I write in place of the comment?
