问题 There are some example for similar question (Progress Bar Java) and (Java uploading percentage progressbar thread) but didn't understand how to make it work for my code. My main has 2 panels one over the other (one of which is a tabbedPane with 2 tabs) public class MainIRH { public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { @Override public void run() { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException |

问题 I'm developing a java application where I save big files using bufferedInputStream. I have put a progressbar inside a JDialog which indicates the percentage of uploaded files and which increases every n seconds. The problem is that the application waits indefinitely for the dialog to close and so it never exits. Anyone can help? here is the main application snippet: JDialog dialog = new JDialog(Main.getMainFrame(), true); ProgressBarJPanel progressBarJPanel = new ProgressBarJPanel(); dialog

问题 I have a JProgressBar on a JPanel as a JList components.The JList components are supposed to update the JProgressBar in every two seconds.But the problem is, I don't know how to pass the value of progress into the JProgressBar. here is my code import java.awt.*; import java.awt.event.*; import javax.swing.*; class download { download(){} } class myPanelListCellRenderer extends DefaultListCellRenderer{ private static final long serialVersionUID = 1L; private JPanel downloadPanel,labelStack;

问题 When I set the min, value, and max of my JProgressBar they do not update unless I close the window and reopen it. Picture: Can anyone give me any insight? I am scratching my head on this one. I tested to make sure that the parsing is done correctly(which is is). I tested to just put numbers in directly. Clearly it works, it just does not show the first time the window is opened(which makes me think that if I update the values it will only show the last values. * EDIT * Ladies and Gentleman...

问题 I'm using nimbus lookAndFill UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel"); and my indeterminate JProgressBar looks like that: http://img15.imageshack.us/img15/9470/uglyprogress.jpg can i make it looks better? 回答1: There's an easier solution. You can just copy the progress bar UI defaults before setting the nimbus look-and-feel and then set them back after. You then get Nimbus look and feel but without its progress bar styling. // copy progress bar defaults

问题 I am writing a program that creates a folder for each file in a specific folder. After that the file is copied in the, just created, folder. Everything works, except the JProgressbar I want to add to the program. I also added a Jtextarea but after a file is copied i want to change the progress bar, and add some text to the JTextarea. while the program runs nothing appears but when the whole task is completed all of the text I want in the JTextArea is shown and the progress bar is 100%. I don

问题 I start my progress bar when the start button is pressed and when my task is completed, I call the function in which I am trying to stop the indeterminate mode of progress bar, but I am still unable to do that (I am using SwingWorker for my application) Here is my code for starting a progress bar; this code is written inside start button: private void StartButtonMouseClicked(java.awt.event.MouseEvent evt) { Main f22 = new Main(); f2.getfile(FileName, 0); f2.execute(); SwingUtilities

问题 I have a JButton ( swing ) in the JPanel , where if it is pressed I am performing a task on the for loop over the list in its EDT thread . While doing so I need to update the JProgressBar . Problem is, when I am pressing the JButton the task is performed in Event Dispatch Thread (EDT). So I can't update the JProgressBar which is triggered either in main or UI thread. Right now the source code is not available at me as I completely changed it and tried to use Eclipse SWT for JProgressBar when

问题 I have tried following tutorials but I keep getting lost somewhere. What I need is a class that creates and displays a progress bar ( JProgressBar ) that I can set the value of as I iterate over data loaded from a file and place into the database memory. My problems come that every example I have found has some kind of counter that fills the progress bar and executes from a "main" function. Every time I alter that tutorial to be a class that I can call at will and display the bar, I do not
