Name: rmT116609 Date: 05/13/2004 FULL PRODUCT VERSION : java version "1.4.2" Java(TM) 2 Runtime Envrionment, Standard Edition (build 1.4.2-b28) Java HotSpot (TM) Clinet VM (build 1.4.2-b28, mixed mode) ADDITIONAL OS VERSION INFORMATION : Windows XP Version 2002 SP 1 A DESCRIPTION OF THE PROBLEM : Setting the background color on JProgressBar does not work in XP L&F in JRE 1.4.2. This used to work in 1.4.1. Even in 1.4.2, with other L&F like metal L&F, it works properly and shows the background color set on the component. With XP L&F, it always shows white background. STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : Compile and run the test case. EXPECTED VERSUS ACTUAL BEHAVIOR : EXPECTED - The progress bar should show with red color as background. When the task proceeds, the progress is indicated by the green foreground color. ACTUAL - The progress bar shows up with white background color, which is then filled with green foreground color. REPRODUCIBILITY : This bug can be reproduced always. ---------- BEGIN SOURCE ---------- import java.awt.*; import java.awt.event.*; import javax.swing.*; public class ProgressBar extends JPanel { private JProgressBar progressBar; public ProgressBar() { super(new BorderLayout()); progressBar = new JProgressBar(0, 20); progressBar.setValue(0); progressBar.setStringPainted(true); progressBar.setForeground(Color.green); progressBar.setBackground(Color.red); progressBar.setOpaque(true); JPanel panel = new JPanel(); panel.add(progressBar); add(panel, BorderLayout.PAGE_START); setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20)); } /** * Create the GUI and show it. For thread safety, * this method should be invoked from the * event-dispatching thread. */ private static void createAndShowGUI() { //Make sure we have nice window decorations. JFrame.setDefaultLookAndFeelDecorated(true); //Create and set up the window. JFrame frame = new JFrame("ProgressBarDemo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Create and set up the content pane. JComponent newContentPane = new ProgressBar(); newContentPane.setOpaque(true); //content panes must be opaque frame.setContentPane(newContentPane); //Display the window. frame.pack(); frame.setVisible(true); } public static void main(String[] args) { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (Exception e) { } createAndShowGUI(); } } ---------- END SOURCE ---------- Release Regression From : 1.4.1 The above release value was the last known release where this bug was known to work. Since then there has been a regression. (Incident Review ID: 265350) ======================================================================
