jprogressbar

问题 I was wondering how I could set my JProgressBar to use the two available styles, as NetBeans does. I've noticed in NetBeans, that when debugging or building a program, the progress bar at the bottom-right of the screen first uses the indeterminate style, but with blocks instead of the oscillations and then switches over to the 'standard' style. I'd like my program to use the oscillating style when the server is starting, and then the blocks style when the server is running. How could I

问题 I understand that 'fluid' isn't the best description, but that's how I imagine the green that lays inside a progress bar. I was just wondering if it was possible to just see the green 'fluid' from the progress bar, and not the container that hold the 'fluid'. The purpose of this is to make artwork under the progress bar that would hold the green 'fluid', rather then the system's default UI holding this fluid. EDIT: This is a photo of the current progress bar in question: The JFrame this is on

问题 I have a server call from the UI. It has response time is little high. So I was thinking to display a progress bar during data loading from the server. I have tried the following code using this approach to show the progress bar. Some where I am doing wrong I am not seeing the progress bar when I call the calculateResult() method on button click. I no need to display any percentage on the progress bar. It just needs to show that data is loading. // The following code I have tried. import java

问题 This question already has answers here : Running a JFrame with a JProgressBar (2 answers) Closed 6 years ago . I am working on a Java program, which reads text files does some probability calculations. Reading files and all related calculations are done in a while loop. I had created a GUI using JFrame, where i had added a Progress bar (using JProgressBar) to show the progress since the program takes a while to process the files. The code looks like - while( there are more files to read ) {

问题 How can I update the JProgressBar.setValue(int) from another thread? My secondary goal is do it in the least amount of classes possible. Here is the code I have right now: // Part of the main class.... pp.addActionListener( new ActionListener(){ public void actionPerformed(ActionEvent event){ new Thread(new Task(sd.getValue())).start(); } }); public class Task implements Runnable { int val; public Task(int value){ this.val = value; } @Override public void run() { for (int i = 0; i <= value; i

问题 is there a way to make the dialog from ProgressMonitor modal? EDIT: The ProgressMonitor class in JAVA API will bring a dialog which is on the top but not Modal. User still has access to the background GUI. I am looking for a Modal dialog to show the progress and also allow user to stop the task in the middle. 回答1: As discussed in How to Use Progress Monitors, a number of factors should be considered when Deciding Whether to Use a Progress Bar or a Progress Monitor.
