I want my JTextPane to insert spaces whenever I press Tab. Currently it inserts the tab character (ASCII 9).
Is there anyway to customize the tab policy of JTextPane (o
You can set a javax.swing.text.Document on your JTextPane. The following example will give you an idea of what I mean :)
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JTextPane;
import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.DefaultStyledDocument;
public class Tester {
public static void main(String[] args) {
JTextPane textpane = new JTextPane();
textpane.setDocument(new TabDocument());
JFrame frame = new JFrame();
frame.getContentPane().add(textpane);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(new Dimension(200, 200));
frame.setVisible(true);
}
static class TabDocument extends DefaultStyledDocument {
@Override
public void insertString(int offs, String str, AttributeSet a) throws BadLocationException {
str = str.replaceAll("\t", " ");
super.insertString(offs, str, a);
}
}
}
Define a DefaultStyleDocument to do the work. Then set the Document to your JTextPane.
