      Description



      Name: yyT116575 Date: 03/12/2001


      C:\>java -version
      java version "1.3.0"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
      Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

      The cursor for a password field does not seem to be correctly reset for a
      when the field is cleared using setText(""). Please run the following code to
      see this problem.

      /**
      * Simple class to demonstrate a problem (?) with JPasswordField.
      * Problem detected on an NT machine running Java version:
      *
      * C:\>java -version
      * java version "1.3.0"
      * Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
      * Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)
      *
      * The problem: The cursor does not seem to be correctly reset for a
      * JPasswordField when the field is cleared using setText("")
      *
      * To replicate: Run this class. A dialog is shown 3 times. It prompts
      * for a user-id and a password.
      *
      * When appears for the first time, enter any text (say 5 or 6 chars)
      * at BOTH the user-id and password fields. Press the OK button.
      *
      * When the dialog appears for the SECOND time, enter some text at
      * the user-id field and then TAB (ie: do NOT use the mouse) to the
      * password field. Note that the cursor is NOT at the start of the
      * field, but is still at the end of the previously entered text for
      * the field, even through the text is no longer displayed!!
      *
      * The third display of the dialog is just an example of using the
      * Caret of the JPasswordField to force it to display correctly when
      * you TAB to the password field.
      *
      * This problem may (??) be related to bug 4139009
