Can I modify a Java Swing JTextArea so that is doesn't display charaters typed? Can I make it display only '*' chars in the same way that a JPasswordField class does?

推荐答案

恕我直言，解决问题的最佳方法是查看 JPasswordField 如何覆盖 JTextField 并自行推导 JTextArea.

IMHO the best way to solve the problem is to look how JPasswordField overrides JTextField and to make your own derivation of JTextArea.
