    Details

    • Type: Bug
    • Status: Open
    • Priority: P4
    • Resolution: Unresolved
    • Affects Version/s: 6u10
    • Fix Version/s: None
    • Component/s: client-libs

      Description

      FULL PRODUCT VERSION :
      java version "1.6.0_10-beta"
      Java(TM) SE Runtime Environment (build 1.6.0_10-beta-b23)
      Java HotSpot(TM) Client VM (build 11.0-b11, mixed mode, sharing)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows XP [version 5.1.2600]

      A DESCRIPTION OF THE PROBLEM :
      The function "getBaseline", used by layout, doesn't work anymore for a button with Html content, in Nimbus LAF.
      It throws an IllegalArgumentException, when the button calls getBaseline on the html content.


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Example :

      public static void main(String[] args)
          {
              try {
                  UIManager.setLookAndFeel(
                  "com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
              }

              catch (Exception e)
              {
                  e.printStackTrace();
              }

              
              JFrame frame = new JFrame();
              JButton button = new JButton("<html><u>test</u>");
              //JButton button = new JButton("test");
              frame.getContentPane().add(button);
              
              frame.setVisible(true);
              
              button.getBaseline(10, 10);

          }

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      A button with underlined text
      ACTUAL -
      Exception in thread "main" java.lang.IllegalArgumentException: Width and height must be >= 0
