why JLabel setText method is not setting up the text dynamically even though i am calling repaint() once i set the text? Code snippet is below
Locale currentLocale = new Locale(panel.getCountryLocal(), panel.getCountry());
ResourceBundle messages = ResourceBundle.getBundle(Constants.messageBundle, currentLocale);
messages = Panel.getMessages();
String displayString = messages.getString("101022");

I have been going in circles trying to update a JTable. For now I just need to take input from a textfield after clicking on a JButton and have that text be placed in the JTable. LeftPanel listens, while RightPanel holds the table. Here is what I have so far:

import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.event.ActionEvent;

I am trying to write an application where if you click and hold down on 1 button and move the mouse to another button and release the text on the 2 buttons should be switched around.I have a print line so I can se the text are supposed to get switched around but it is just not happening in the GUI.
I attached all my code in case the flaw was to find somewhere else in the code, but the functionality I am working on is the lines 76 to 121.

Create a dnd (dungeons and dragons) character creator and back ground generator, have it display and run on a gui, to start with i decided to creator the gui as i go so i can see the progress, first i tried eclipse and windows builder, well after 1 day of reinstalling windows builder in about 5 different ways from multiple guides and sometimes getting it to partly work ...
After doing some more research I have figured out how to get the main program to display the gui . Heres what i have:
package com.mrgreaper;
import javax.swing.*;
public class MainWindow {
private JPanel mainWindow;
private JLabel playerlbl;
private JLabel playerNamelbl;
[Code] .....
Now this works fine and the gui displays when the program is run but I can't change the text of any of the jlabels or textfield. If I try to do it in the main class i need to change them from private to public static but then in the form builder it says "cannot bind to static field *name of field*" but if i take static off then i cant change its value!
From what i understand this is because the window is an instance, so how to i change the value in that instance? I could put all my code in the one class, the one that creates the gui, but i really want it seperate, i would like the gui to update as the code runs... So how do i do it, how do i change the contents of jlabels on the fly, read the contents of text boxes on the fly etc....
I tried adding a getter setter
public void setCharFirst(JLabel charFirst) {
this.charFirst = charFirst;
}
in the MainWindow.class
Then i tried to set it from my main function
MainWindow.setCharFirst("test");
but it cant access it as my main function is static and it is not now can i make it static...

I am trying to Make A GUI which has a Jcombo box i also want it to have a jlabel that up dates depending on which option the user selects from the JcomboBox
for exampl if i select lion i want it to say you chose lion on the Jlabel and if i choose ostrich i want it to say ostrich and so on
I want to create 3 JTextFields in a row with all being of equal size.But my first Text field gets so wide than the other two.After adding each component at a time and seeing what causes the problem I realized that if I type a long text for the JLabel that's when this problem occurs.If I reduce the length of the text in the JLabel JTextFields get into the sizes I want. Here's my code
import java.awt.*;
import java.awt.event.*;
import java.lang.Math;
public class Calculator1 extends JFrame {
JTextField value1=new JTextField("0");
JTextField value2=new JTextField("0");

How can I stop the JTextFields changing size when I change the JLabel label1's text length...
I don't get what I missed in the code. I used the example of changing the text of a button by clicking on it, but instead I also added a JLabel and tried to make the button change its text instead, but it didn't work. What did I do wrong?

I have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description
TextArea textArea = new TextArea();
Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT
text.setText(usrNotes.getNote().trim());

I am generating textfields dynamically using JSTL forEach. Here is the code ..
<c:forEach var="underlyingTickers" items="${underlyingTickersList}" >
<tr>
<td ><input name="underlyingTickers" type="text" id = "underlyingTickers" value="<c:out value='${underlyingTickers}' />">
</td>
</tr>
</c:forEach>
If there are 4 values in underlyingTickersList A, B C, D and E ... I am getting those values correctly displayed in each text field.
However if I submit the form with all these value how can I get it in the bean? I guess I need to have dynamic id or name for each text field. How can generate it?
Note** I dont have Struts framework.. I am using request.getParameter to fetch the values and set into the bean variable.
I'm using NetBeans.
I have a JFrame with four JPanels, SensorLL, SensorLC, SensorCR and SensorRR. They are instances of the class SensorUI. Each has a JLabel called Sensor.
The class SensorUI has a method writeSensor that writes to the JLabel "Sensor". I will have four temperature sensors. I have not started the code to read the temperature sensors yet. I will have a timer that will run once a second. When it fires I will read the sensors and display the result in the
JLabel "Sensor" in each jPanel.
I use MyMain to call FrameDemo and create the JFrame and a method
in FrameDemo to add the JPanels using addObject.
I can use SensorLL.writeSensor will write text to JLabel Sensor while in Mymain.
Then I start the timer ReadSensor.
When it times out it calls SampleSensors
For an experiment, while in SampleSensors I try to write to the JLabel in the instance SensorLL with
SensorLL.writeSensor("xx_");
I can't because it says it can't find the symbol variable SensorLL in SampleSensors class.
How can I "get to" that JLabel text when ever I need to?
Java Code:
public class MyMain {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
//SensorUI SensorLL = null;
System.out.println("Start of main");
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
FrameDemo.createAndShowGUI();

The code was,
messageLabel = new JLabel("Top buttons change the panel color and bottom radio buttons change the text color.");
messageLabel.setHorizontalTextPosition(SwingConstants.CENTER);
messageLabel.setVerticalAlignment(SwingConstants.CENTER);
The text always displays in top-center part of the center panel. i want to align it as center-center horizontally and vertically. The problem could be, bcoz the jlabel text is inside a constructor but im not sure. The whole code is

I have four buttons with different names and depending on which button is pressed I want to change the label to be displayed. Center is the name of the label the other directions are buttons. The label should change if a different button is pressed. The error I get is that it cannot be converted to String.
public void actionPerformed(ActionEvent event){
Object source = event.getSource();
if (source == east){
center.setText(east);
}
if (source == west){
center.setText(west);

Ok, so I am trying to learn about JFrames and JPanels. I have figured out buttons, layouts, etc. What im having trouble with is accessing the label object from the ButtonHandler class since it is static and I need my JLabel to be non-static so that it can change. Basically, I want JLabel to change to a pre-determined text string once a button is pressed. Here's what I have so far

i want to draw a circle inside a circle in java. so far i'm using this piece of code
private Ellipse2D.Float drawEllipse(int x1, int y1, int x2, int y2) {
int x = Math.min(x1, x2);
int y = Math.min(y1, y2);
int width = Math.abs(x1 - x2);
int height = Math.abs(y1 - y2);
return new Ellipse2D.Float(x, y, width, height);
}
I am working on a project in Eclipse, and it is my first time working with swing.I have the GUI setup the way that I like it, my hang-up is how to "update" the variables in the code as they are changed.The basics of the code is that I have several different String[] that will show up in a Jtable depending upon the input of the lists I have in the GUI.
in essence,
if list1==2 && list2==3
returnedarray = array1
I would like to have the returnedarray/Jtable be updated live as the lists are manipulated. So as soon as I change my list selections to...
list1==1 && list2==3
the code would shift to the proper array...
returnedarray = array2
If making the output update live isn't a possibility how would I code a button to update the input/output giving me the proper String[]?
I am using a HashMap to store names (keys) and IDs (values). I have set it up so that the radio buttons are added to the JPanel dynamically. That is, each time a name/id is added, a new radio button is automatically generated and added to the panel. Here is a snippet of the code I have thus far:
private void employeeButtons() {
buttonPanel = new JPanel();
buttonPanel.setLayout(new GridLayout(5,2,5,5));
empMap.put("Kyle", "1090");
empMap.put("Alex", "6490");
empMap.put("Mark", "9090");
empMap.put("Anne", "4390");
[code]...
The above code adds all of the radio buttons to the panel just fine. However, I need the buttons to be mutually exclusive. I would like to be able to not only add the buttons dynamically, but I need the buttons to be added to a ButtonGroup dynamically as well. That is, when I add a new hashmap entry the a new radio button is generated and added to the radiobutton group.
Am trying to add buttons dynamically in a new Jpanel on click of a button. i am getting new Jpanel but not able to see the buttons.
btnNewButton_1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if((!(playerFirst.getText().equalsIgnoreCase("") ||playerSecond.getText().equalsIgnoreCase(""))&&(!playerFirst.getText().equalsIgnoreCase(playerSecond.getText())) ) ){
//unoGameController.playGame(playerFirst.getText(), playerSecond.getText());
CardLayout cardLayout=(CardLayout)(frmUno.getContentPane().getLayout());

panel_player1.add(btnArr[i]);
}return unoDeckMain; }
Am i skipping something ?
I have this method that does several RegEx queries along with a lot of searching and replacing of text, and each regex search / replace takes some time and a total of maybe two minutes for all of them to finish up. So I added a ProgressBar to my JavaFX form and I added code after each step to simply use the ProgressBar.setProgress method by a factor of 10% each step ... so the code would resemble something like this:
do a regex query
if it finds things then do a replaceAll method on the string being searched
ProgressBar.setProgress(.1)
do another RegexQuery
If it finds stuff, so a replaceAll method
ProgressBar.setProgress(.2)
etc...
What is happening is that the progress bar will not actually paint any progress until AFTER the entire method is done executing. So from the users perspective, they click on the button and the program appears to freeze until its all done with that method at which point it instantly changes the progress bar to the last value I set ...
So the desired effect is simply not working, and I don't know why.
I tried changing (as in replacing the progress bar with a different control) the progress bar value settings with updating text in a text box on the form, and even that didn't display any of the text messages until AFTER the procedure was done executing at which point, all of the text logs appeared at one time instead of gradually adding text to the box in increments as the method executed.So it FEELS like any time a method is actually running, the JavaFX scene simply freezes until the method is done running. And it doesn't matter if I change the progress bars value directly or put it into its own method which gets called throughout the execution of the regex method ... either way, nothing actually happens on the form until the software is done executing all of the procedures called and then it comes back to a "resting" state...
I tried simplifying it by making a single method that does two things ... it updates the progress bar and then it waits for 1 second. Then it increments a variable then updates the progress bar, then waits a second, thinking to myself that 1 second pause would give it time to update the progress bars value but even that little method would not work.
Here is the test method I created:
private void testProgressBar() {
for(int x = 0;x<10;x++) {
progressBar.setProgressBar(.1*(x+1));
try {
sleep(1000);
}
catch(InterruptedException e) {
e.printStackTrace();
}
}
}
Even that little piece of code will not actually show any changes in the progress bar until after its done looping at which point, the progress bar is filled to 100%, but I never see the first 9 changes in the progress bar within that for next loop.
I wrote a simple random spelling game for a class project, was never able to get the labels to update when they should. I have tried .updateUI, .paintImmediately followed by .revalidate and by .repaint. Nothing seems to be working.
What the game does is show a random word for about 10 seconds, disappear and they user is to spell that word, you have 3 tries then will start over. The "brains" of the game work just fine, it is the labels updating with new text when they should doesn't seem to be working. There is 4 classes but the below is the "Main" that has the problems. Also have a null exception problem with the timer.stop(); not sure why. I am still pretty new to java.
Public class SpellMe extends JFrame {
// variables
JPanel mainPanel, secondPanel, thirdPanel;
JLabel mainLabel, wordLabel;
String spWord, sp;

I am building a GUI application which consists of two panels "panel" and "panel1". "panel1" have a button "addTimer" when clicked it should add the "panel" to the frame if i gain click the button it should again add the "panel" without overlapping the previous "panel" rather it should be created below the previous "panel". If i click on the button "addTimer" n times it should add the panel n times. Along with this the frame size has to dynamically change depending on the number of panels produced. Below is the code i tried my level best to satisfy the above conditions.
