<Swing Dev> Question about bug 4512626

[Sean Chou]

Hi all,

    I'm just working on a similar bug like 4512626, so I wrote a simple
testcase for 4512626.
However, I think 4512626 is not in the state as described in its comment.
   The comment says:

"

    MS Windows indicates the focus of uneditable text component by
displaying a flashing caret. We could make the same thing with
JTextField, JPasswordField, JFormattedTextField and JTextArea.
For Windows LAF we could make this without API changes just by
overriding createCaret() in corresponding UI classes.

"

I tested these 4 components in windows LAF and found they are not
displaying the caret at all.

Is that because it was thought "won't fix" ?

        txtJtextfield.setColumns(10);

        btnWinLf = new JButton(LAF);
        contentPane.add(btnWinLf);

    }
}
