alternating font color

[droidus]

i would like to alternate my font color. the code that i have right now changes all of the text. how can i get it so that it will only update one line color at a time, rather than the whole text area font?

private void sendTextActionPerformed(java.awt.event.ActionEvent evt) {
		String temp = input.getText() + "\n";

		if (toggleUser.getSelectedItem().equals("User 1")) {
			update1.setForeground(Color.red);
			update1.append(temp);
		} else if (toggleUser.getSelectedItem().equals("User 2")) {
			update1.setForeground(Color.BLUE);
			update1.append(temp);
		}
	}

A JTextArea can't do that (it uses the 'font color' for all the text). Have a look at the JTextArea class or the JEditorPane class.

kind regards,

See: Text Component Features (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components). It shows how you can use attributes on a JTextPane.
