I have a datagrid in which i have to display progress bar with the task completed in %.
For example i have two fields in a table source count and completion count.
Where source count in 100000 rows and 50000 rows have been inserted.
In another table and status is displayed in the table.
So I need to display in a progress bar that 50% task has been completed.
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.
i was uploading file to drop-box using java.But the problem is how can i add progress bar to file upload to drop-box.I didn't use java script for it.I didn't get any of this in drop-box API. my code is.

import java.io.*;
import java.util.Locale;
public class Main {
public static void main(String[] args) throws IOException, DbxException {
// Get your app key and secret from the Dropbox developers website.
final String APP_KEY = "INSERT_APP_KEY";

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?
I have this method:
Java Code:
public static void listFiles(String path) {

list = root.listFiles();
if (list == null) return;
for (File f : list) {
if (f.isDirectory()) {

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?
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?
I want a progress bar when checking the sha1 . When getting the sha1 there we see the progress of checking

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();

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();

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

private JProgressBar _progressBar = null;

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.
Since the upgrade to JavaFX 8u20 my ProgressIndicator won't rotate anymore when using Caspian style. Is there any workaround for this?
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ProgressIndicator;
import javafx.stage.Stage;
public class TestApp2 extends Application {
public static void main(String[] args) {
[Code] ....
If I "embed" a ProgressIndicator inside a ListView it has an ugly border and a white background. It looks like there's a TextField below the ProgressIndicator.
Why does it behave like that and how to solve it so that the progress indicator is transparent.
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.scene.Scene;
import javafx.scene.control.ListCell;

Here's what "Why doesn't this work?" question. It concerns a small method which is part of a card game.
I'm trying to check a condition from a section of an array, without a predetermined number of times any given call to this method will require a check. How much of the array I'm checking could vary greatly.
Is it at all possible to nest a for loop yielding a variable number of boolean && conditions inside an if? Am I just missing the right bracketing or is this nesting (if that's the word) even possible in the language?
To clarify, below is broken code. Compiler isn't letting me accomplish this goal as I envision it.
public boolean isFlanking() {
boolean f;
int reach = Math.abs(selectorX - targetX);
if(rival.getDeck()[selectorX].getPile().isEmpty() == true &&

Basically the problem is I've been trying to loop my switch (if this is even possible) until the user enters a correct number between 1 and 4. But for some reason when the user enters a correct number (1,2,3,4) the loop runs again. Even when the user enters a wrong number the switch ignores the default and repeats what is in the do.
Am I just trying to loop something that cannot be looped or have I gone?

Basically, I am trying to write a method that will take a string, a target, and a replacement (a replacement function like string.replace). I want it to replace all instances of target with replacement EXCEPT for instances that occur within single or double quotes.
Example input / output:
this "Wont" be " replaced, be"
call: replace(theString, "replaced", "narf") and replace(theString, "be", "rafn")
output:
this "Wont" rafn " replaced, be"
In some examples I see jsf components inside the tag view, other times dont.
- Is it important to put all jsf components inside "the view" tag?
- What would be the difference not putting them inside this tag?

Write a program that accepts as input three positive integers representing the diameter of the cigarettes to be packed and the dimensions of the pack to be used. The required output is the maximum number of cigarettes that can be packed without damaging/re-sizing the cigarettes or packs
NOTE: the diameter of cigarette is 1 and 2 only.
Example: Diameter is: 1 and dimension1: 2 and dimension2: 4
the output is. Maximum number of cigarettes can be put on the pack is 6.
ex.2 diameter is 2 and dimension is 10 and dimension2 is 17
the output is. The maximum number of cigarettes can be put on pack is 40.
ex.3 diameter is 2 and dimension is 5 and dimension2 is 7
the output is. The maximum number of cigarettes can be put on pack is 6.
I just need the formula to get the number of cigarettes that can be put inside on the pack on its dimension.

View Replies View RelatedAs I couldn't find a way to do the printing of multiple items on one page, I decided to test out my idea. I found that I could have a table in a JTextPane.
However, whenever I got to print, my table will vanish. It doesn't even need to go to the printer. Just bringing up the print dialog will make it vanish like tax money in D.C.
(Also, I'm not really that familiar with JTextPane and it seems harder than JTextArea. Which part is controlling the font of my regular text by the way? I think it might be tableParagraph but it could also be the base font. I can try and fiddle with both and waste paper but where the font is being set.
Setting the font with setFont() will vanish my table. )
Somehow, I'm thinking that the solution might be JTextPane.setContentType() or setEditorKit() or both. (I"m not that familiar with either, but I fear that it's only being set to handle text, hence any graphics are being lost.)
Here is my code:
import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.text.*;
public class AddingTables {
JTextPane textPane;
private Object[][] rows;
private Object[] colNames;

I want to put my table inside a form for retrieval purposes (or Am i doing it wrong?) When the table is not within a form, it works perfectly. It displays information the way i wanted.
However, once I put the table inside a form the table doesn't display needed information. Is the problem the html or the jsp code?
Here's my jsp file:
<form action="deletemovie" method="GET" id="deleteForm">
<table class="table table-striped table-responsive table-hover">
