      Original user synopsis: "The text in a horizontal progressbar is not placed in the (vertical) middle"

      When using a horizontal JProgressBar with
      setStringPainted(true), the string is not
      painted in the (vertical) midle of the progress
      bar.
      This becomes a visible problem when the height
      of the progressbar is reduced below the
      preferred size.


      Example program:

      import java.awt.*;
      import com.sun.java.swing.*;

      public class pbar {
          public static void main(String[] args) {
              new pbar();
          }

          public pbar() {
              JFrame frame = new JFrame();
              frame.setSize(new Dimension(300, 200));
              JProgressBar bar = new JProgressBar(0, 2);
              bar.setValue(1);
              bar.setStringPainted(true);
              frame.getContentPane().add(bar);
              frame.setVisible(true);
          }
      }



      The comment in the BasicProgressBarUI.java source
      hints that the text should be draw in exact
      middle:

      /**
       * Designate the place where the progress string will be drawn.
       * This implementation places it at the center of the progress
       * bar (in both x and y). Override this if you want to right,
       * left, top, or bottom align the progress string or if you need
       * to nudge it around for any reason.
       */
