- A JPasswordField is much like a JTextField, but it echos an '*' instead of the text the user typed.
- You can change the echo character in the constructor.
- For better security, it has a getPassword() field that returns a character array.
- With the JTextArea, you can use a constructor to specify the number of columns and rows.
- Example: JTextArea txtEssay = new JTextArea(4, 30); will make a JTextArea of 4 rows and 30 columns.
- By default, text that goes beyond the JTextArea component is clipped, or scrolled out of view. You can wrap long lines by using the TextArea method setLineWrap(boolean b);
- Of course, you could give the user this option by having a button that calls this method on the JTextArea object on the button listener's actionPerformed(ActionEvent e) method.
- But, if you want scroll bars, you must add the text area to a JScrollPane object. Do that like so:
- Note that you add the JTextArea object to the JScrollPane, and then the JScrollPane to the container (JPanel or JFrame). You do not add the JTextArea object directly to the JScrollPane object. Or, again, just let Forte' do it all for you.
JTextArea txtEssay = new JTextArea(4, 30)
JScrollPane scrEssay = new JScrollPane(txtEssay);
pnlEntry.add(scrEssay);
