RE: JOptionPane and passwords

[Kevin Snow]

Here is some code that should do what you want:

                    JPasswordField passwordField = new JPasswordField(20);
                            JOptionPane optionPane = new JOptionPane();
                            optionPane.setMessage( new Object[] { "Please
enter a password:", passwordField } );
                            optionPane.setMessageType(
JOptionPane.QUESTION_MESSAGE );
                            optionPane.setOptionType(
JOptionPane.OK_CANCEL_OPTION );
                            JDialog dialog = optionPane.createDialog( this,
"Password" );
                            dialog.show();
                            Integer value = (Integer)optionPane.getValue();
                            if ( value == null || value.intValue() ==
JOptionPane.CANCEL_OPTION
                                || value.intValue() ==
JOptionPane.CLOSED_OPTION )
                            {
                                dialog.dispose();
                                return;
                            }
                        System.out.println("Password = " +
passwordField.getPassword());
                            dialog.dispose();

Hey,

You can pass a JPasswordField as the message parameter.

>From the JavaDoc of JOptionPane :-
the parameter message can take the following types of values -
message
A descriptive message to be placed in the dialog box. In the most common
usage, message is just a String or String constant. However, the type of
this parameter is actually Object. Its interpretation depends on its type:

Object[]
An array of objects is interpreted as a series of messages (one per object)
arranged in a vertical stack. The interpretation is recursive -- each object
in the array is interpreted according to its type.

Component
The Component is displayed in the dialog.

Icon
The Icon is wrapped in a JLabel and displayed in the dialog.

others
The object is converted to a String by calling its toString method. The
result is wrapped in a JLabel and displayed.




Hope this helps
Regards
Sachin
