jprogressbar

问题 QUESTION SOLVED!!!!!! Many thanks to trashgod and HoverCraftFullOfEels! I finally got the concept by using the below example and altering it slightly. The alteration allows scaling the progress bar (by default is 100 units). Again, THANK YOU for your patience and willingness to work through this. Means a lot guys, ~Kyte ps - +1's all 'round :) /** @see http://stackoverflow.com/questions/4637215 */ public class Threading_01 extends JFrame { private static final String s = "0.00"; private

问题 I'm trying to change the color of a single JProgressBar in Nimbus LAF (Look And Feel). This solution does work, but it changes the colors of ALL JProgressBars :/ UIDefaults defaults = UIManager.getLookAndFeelDefaults(); defaults.put("nimbusOrange",defaults.get("nimbusBase")); In this thread is another solution to change the color for each JProgressBar individually: progress = new JProgressBar(); UIDefaults defaults = new UIDefaults(); defaults.put("ProgressBar[Enabled].backgroundPainter", new

问题 I know the subject has already been seen on many Questions and has been answered, but still, I can't get trough it. I just want to update a progressBar while extracting some stuff of a large xml file. I thought it was enough to have the time-consuming loop in a different thread but ?.. All I managed to get is the progressBar either not showed at all, or updated at the end, just before it's closed. Instanced somewhere near the launch of the application, I have: public class SomeClass { private

问题 I tried out the function of the JProgressBar in Java. But there is a problem I couldn't solve: When I set the minimum to zero, the maximum value to 100 and the current value to 6 then nothing will be displayed. The progress bar is empty. If I put 7 as current value then it works. It seems to be a problem with any empty border or other space. The problem occurs with Windows 7 and only if the UIManager is set to SystemLookAndFeel. Does anyone knows this problem and has a solution for this?

问题 The following is a simple code for converting an image to byte array (Which is already shown in this forum): File imgPath= new File(textFiled_Path.getText()); BufferedImage originalImage = ImageIO.read(imgPath); ByteArrayOutputStream baos = new ByteArrayOutputStream(); ImageIO.write(originalImage, "png", baos); baos.flush(); byte[] imageInByte = baos.toByteArray(); However, when the image size is big, the program takes too much time to convert. Therefore, I'm thinking of adding a JProgressBar

问题 i'm developing a little GUI application with Java using Netbeans Editor. I've put in a JFrame a simple Progress Bar. I'm developing the project with JDK7 I want to change the background Color from default Orange to a personal one. I've already tried all the properties for the color changing but when i run the program the color still the same. I've already tried using ProgressBar1.setBackground(new java.awt.Color(0, 204, 255)); and UIManager.put("ProgressBar.background", Color.YELLOW);

问题 I have made a very simple code to show it here, i have a button that should show a JDialog to check the progress status, i am using the invoke late to go through EDT and my loop isn't in the run method, so why isn't my bar updating ? here is the code import javax.swing.JButton; import javax.swing.JDialog; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JProgressBar; import javax.swing.JTextField; import javax.swing.SwingUtilities; import

问题 I have a SwingWorker class which loads a text file and slices it to chunks for further processing. This is the SwingWorker class: public class ConverterWorker extends SwingWorker<String, String> { private final File f; private final JLabel label; public ConverterWorker(File f, JLabel label) { this.f = f; this.label = label; } @Override protected String doInBackground() throws Exception { NMTMain.convertableData = getDataSets(f); if(!NMTMain.convertableData.isEmpty()) { return "Done"; } else {

问题 If I really wanted to do something like that, can I put a JProgressBar (or it's equivalent) in a JTabbedPane tab? (I mean, not in the tab itself, How would I do something like that? EDIT I really do want to put the progressbar in the title of the tab, not the tab itself. Here's some ascii art: ---------------------------------------------------- | Tab 1 || Tab 2||Tab-with-progress-bar||Tab 4| ----------- -------------------------------- ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ------------------------
