      Description



      Name: krT82822 Date: 03/07/2000


      orig synopsis: "one long line in a JTextArea is SuperDuper Slow"

      java version "1.3.0rc1"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0rc1-T)
      Java HotSpot(TM) Client VM (build 1.3.0rc1-S, mixed mode)

      I have a JTextArea with a vertical scroll bar as needed, it word wraps, and has
      a non-default font set. Type in one long line of text without no enter keys.
      Like 4-10K. Now try to type on that line. The speed is horribly slow. If you
      wanted to make Swing appear faster due to this new JDK, this would of been one
      of the things I would have expected to been fixed (sped up). But swing still is
      really slow.

      Also, screen flashing on a JDialog appearing still occurs. I do not mind the
      time it takes to come up, but have it appear on the screen nicely. This would
      be one more thing needed to make swing appear faster. The flicker I am talking
      about even appears on the JFileDialog a little.

      But the two things I wanted fixed to make things look faster, still are not
      fixed in the new JVM.
