JTextArea - Selected Text > Bold, Ital., Underlined

Hello,

I have a word processing program where I want the user's selected text to become bold when the bold button is pressed, but I can't figure out how to set the selected text as something else. JTextArea has a method:

textArea.getSelectedText()

that returns a String, but I can't quite figure out how to replace it with the new text.

Please help.

Thank you!

Use JTextPane instead of JTextArea.Then you can replace the selected text with styled text.Read the tutorial: http://java.sun.com/docs/books/tutorial/uiswing/components/editorpane.html

Thanks, but I'm not quite familiar with JTextPane, and I use textArea.append() a lot in my program; JTextPane doesn't have an append() method.

> a lot in my program; JTextPane doesn't have an append() method. Then write your own. Look at the source code for the JTextArea.append(...) method.

Where do you get the source?

Its in a file src.zip that comes with the JDK. At least thats where is was in JDK1.4.2. Read the documentation of the JDK and I'm sure you will find it.

Quick question: If I'm using Eclipse, where would it be?

public void append(String str) {

Document doc = getDocument();

if (doc != null) {

try {

doc.insertString(doc.getLength(), str, null);

} catch (BadLocationException e) {

}
