Swing/AWT/SWT :: Update Progress Of A Process In Progress Bar - Java GUI

Nov 29, 2014

In my Java SWT application, I have few methods, that take longer time to complete. These methods has to be initiate and run as response to button click. There I want to implement progress bar to show the progress/status of long run method. Long run methods are Java Processes, in which it executes some command line functionality. (ex: run ls method in Linux).

Process p = Runtime.getRuntime.exec(command)

In progress bar status is set using setSelection method which takes int as argument. How to indicate the progress of process in progress bar, because I don't have int value to pass into setSelection method of progressbar.

Swing/AWT/SWT :: Progress Bar Not Working?

Feb 14, 2014

I'm trying to get a progress bar to work on my GUI.

This is what I have so far, the parameters are taken from another class that takes in an image in packets from a Raspberry Pi and stores them to a file on PC.

public void ImageInfoReceivedHandler(int sizeOfFile) {
progressBar.setMinimum(0);
progressBar.setMaximum(sizeOfFile);
progressBar.setIndeterminate(false);

[Code] .....

The println are printing out the correct values and they are being implemented in the methods, but nothing is happening in the GUI.

I have a thread setup in the GUI when a button is pressed

getImageButton.setText("Timer Started");
transmit = new transferImage(port);
lblImgProcess.setText("Getting Image, Please Wait");
transferThread = new Thread(transmit);
transferThread.start();

So the thread starts and image is then transmitted, does the progress bar need to be in that event handler?

Getting Progress Of Reading Disk?

Oct 16, 2014

I have this method:

Java Code:

public static void listFiles(String path) {
File[] list = null;
File root = new File( path );
list = root.listFiles();
if (list == null) return;
for (File f : list) {
if (f.isDirectory()) {

[code]....

How would I get the overall progress of reading the directory I give to it, for example, if I give it the root directory of my computer, it would read through ALL my files and folders, and that works fine.But how would I get progress for a progress bar?

Progress Monitor Not Showing

Mar 27, 2014

I thought that simply constructing a progressmonitor would show the dialog, and wrote the following code.

[Code] ....

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.beans.*;
import java.util.Random;

[Code] ....

But apparently i was wrong and all i get is an empty JFrame and no Dialog. I even added my own subclass of SwingWorker in case a SwingWorker had to be created in order for a progress monitor to exist. How can I make it show?

Progress Bars (can't Start And Won't Count Down)

May 5, 2014

I'm trying to get a timer to work to decrease the value of a stats bar (like Hunger Level, Energy Level), but it won't paint the bars in the first place, it won't let me start the timer (the start after t.start() is underlined) and now I'm getting an error that won't let me run it at all without putting public static void main (String [] args), even though adding it anywhere is causing other errors

public void hungerTimer () {
int delay = 300;
int period = 300;
interval = 100;
hungerBar.setValue(100);
hungerBar.repaint();
timer = new Timer();

[Code] .....

Swing/AWT/SWT :: Multiple JFrames - Thread And Progress Bar

Mar 29, 2014

I'm struggling with a small project. I have 2 jFrames. The first frame has a button that...

- Display's the second frame containing a progressbar
- Starts a heavy processing thread

I need to update the progressbar on the second jFrame, from a thread started on the first jFrame.

I have 2 problems:

- How do I update the progressbar?
- When the button is clicked, an empty second frame is displayed with no controls. The controls are only rendered/shown, after the large thread process is finished...

I've attached to this post a small screenshot, showing the main idea ...

Source code:

Button action on the first frame:

private void btnGoActionPerformed(java.awt.event.ActionEvent evt) {
Progress progress = new Progress(); // The second frame
progress.setVisible(true);
clsProcess myProcess = new clsProcess(); // The thread process
myProcess.start();

[Code] ....

Swing/AWT/SWT :: Progress Bar Dialog Sometimes Doesn't Display Components

Mar 7, 2014

I wish to display a progress bar during a lengthy file translation process. When I created a ProgressBar class to do this and tested it with a short test program, it seemed to work fine. But when I add my ProgressBar class to a package containing various other classes, put that package in a jar file, and then execute the class using the progress bar from a menu in my main program, the frame of the progress bar shows up with the appropriate caption but the JLabel, JProgressBar, and JButton are not displayed. I have gone over my code numerous times and checked that the ProgressBar class constructor is getting the proper arguments.

// package gov.nasa.jpl.ephemeris;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
/**
* Progress bar with message text above the bar and a Cancel button below it
*/
public class ProgressBar extends JFrame {
private boolean _cancelled = false;
private JProgressBar _progressBar = null;

[Code] ....

I have also been wondering whether I need a separate instance of the border for each panel, or whether I can just create one instance and use it for all three panels.

I am creating a web application that runs on server X(unix) and it has another unix system mounted on it. I want to generate the file tree structure of this mounted unix file system and show it on to a web application so that users can select a file and move it onto this current unix machine.

I know this sounds stupid and you may want to say why cant we directly copy the file, I am doing a proof of concept and using this as a basis.

Read Text File Into Object Array And Creating Random Access File

Dec 8, 2014

I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...

The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data.

Here is the base Product class that must be used to create the objects for the array.

public class Product
{
public String pName;
public String stringName;
public double price;
public int quanity;

[Code] .....

And then here is the data from the text file that i must extract to use to create product objects.

Dill Seed,938,34
Mustard Seed,100,64
Coriander Powder,924,18
Turmeric,836,80
Cinnamon (Ground Korintje),951,10
Cinnamon (Ground) Xtra Hi Oil (2x),614,31
Cinnamon (Ground) High Oil (1X),682,19

These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....

Read Text File Into Array Ask User To Save File And Print Data

Jul 14, 2014

New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows

(1) The original list of N numbers from the input file,
(2) The original list of N numbers printed in reverse order of how they appear
in the input file.
(3) The sum and average of these numbers,
(4) The minimum of all the numbers,
(5) The maximum of all the numbers.

import java.io.IOException;
import java.io.PrintWriter;
import java.io.Writer;

Read Input File And Create Output With Anagram For Words In File

Sep 24, 2014

Well my code is supposed to ask for an input file and then (ex: input.txt), read the input file and create an output.txt file with the anagram for the words in the file. Also it should be displayed on the screen. However my code doesn't display the anagram on screen or the output file!

Heres is the code:

import java.io.*;
import java.lang.*;
import java.util.*;

/* This program will read a file given by the user, read the words within the file and determine anagrams of the given words. If the file that the user inputs is empty, then the program will output "The input file is empty."
* The program will read the file line by line, counting the total number of words read. If there are more than 50 words, "There are more than 50 words."
* will be printed, and the program will terminate. After each line is read, the words in the line will be separated,punctuation characters will be removed, and upper case characters will be switched to lower case.
* If any word is larger than 12 characters, that word will not be considered in the total amount of words in the file and it will not be sorted.
* After each word is read, the letters will be sorted and stored into an array containing each
* word's 'signature'. After all the words have been read, words will be printed to the output file on the same line based upon their signature.
*/

public class Anagram {
//Creating constants for maximum words in file and maximum chars in word
