How can i code this differently so that when i click one of the button it changes the image to the red.jpg or green.jpg?
Java Code:

I have a JButton with a .PNG icon on it. I want to get that button click in actionPerformed Method but Jbutton have no Label... How i will know that which button clicked?
View Replies View RelatedI have a button whose text is being cutoff. How can I tell javafx that the button should be as big as the text in it and so no cutting off text happens?
View Replies View Relatedwhy this code doesnt work? Its suppose to be a simple frame with a button that puts text to the frame when u click it. The problem is actionPerformed method, when it tries to call the stuff inside the constructor it all goes wrong. I switched the method body with a system.out.println() and it all works fine.
import java.java.awt.Label;
import java.awt.Button
import java.awt.BorderLayout;

public class TheClass implements ActionListener {

How can i add a background image for this code without disappearing the button and label? I want a frame that has a background and still shows the buttons and label that I place. and how can I insert Buffered Reader in this code, this is a file organizer, but it only shows first line of a text file. I want to show the whole text file. And is it possible to also show path of the file?

I am using JS, how we can make focus to a button during onload, the button need to get focus which is in tabbedPane tab Name : (Search Critera1) using javascript.
View Replies View RelatedSo I just processed this rectangular array and made myself a table. I want to put a label for each column to identify what the values are. My attempt at this failed miserably, because it looks horrible. Here is the necessary code.
Java Code:
System.out.println();
System.out.println("FORMATTED RESULTS");
System.out.println(results);
values[rowCount][0] = currency.format(monthlyInvestment);
values[rowCount][1] = percent.format(interestRate/100);
values[rowCount][2] = Integer.toString(years);
values[rowCount][3] = currency.format(futureValue);
rowCount++;
[Code] .....
If you are to compile this yourself, you would see the horrible output at the end. I would like to know how to properly align each label with its corresponding column.

public class DisplayFinal_Panel extends JPanel {
private JLabel label1, label2, label3;
private JTextField box;

I only want Listener 1 to work right now. Also, user input is in TextField.
I'm doing a software Java GUI - JFrame form like this:
1. The user wants to click on a button that opens a bunch of images that will be displayed as thumbnail in the bottom of the JFrame .
2. Then the user wants to select/click one of the thumbnail and make appear the corresponding image in it's original size on above(center) of the JFrame.
For doing this I used 3 JPanel.
One contains a JButton that opens the jfilechoser dialog window,
the second "panelPreview" is for putting the thumbnails created,
and the third "panelGrande" is for the image in it's original size.
The firs part "1." is ok.
But in the second part : I got one error when I want to put the ImageIcon in to the JLabel with the further intent of displaying it.
lblBig(imgIcoVett[i]);
In this project I'm dealing with arrays of ImageIcons and JLabels, so it's a bit advanced level for me, so I'm not sure that I wrote right the part of the MouseListener too.
The error displayed by netbeans says "cannot find symbol symbol: method lbl (ImageIcon) local variables referenced from an inner class must be final or effectively final"
Here I attach the project I did with netbeans"AAAD Unlayout 2.zip", but if you just need the highlight of the code, here it is too:
private javax.swing.JButton btnOpenfile;
private javax.swing.JFileChooser jFileChooser1;
private javax.swing.JPanel jPanel1;
private javax.swing.JLabel lblBig;
private javax.swing.JPanel panelGrande;
private javax.swing.JPanel panelPreview;

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
package makewindow;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

So obviously I'm new to java and i need to write a program that gives exact change in quarters, dimes, nickels, and pennies. For some reason it seems to work correctly but the nickels never is correct and I'm not sure why, seeing as though everything else is.
Java Code:
public class Coins{
private int c;
public Coins(int coins){
c = coins;
}
public void calculate(){
int quarters = c / 25;

I need a code to get a text from a textField to a label but the label is on a different frame, i will give u an example of what i have so far. so this is the main:
package albaestate;
public class AlbaEstate {
public static void main(String[] args) {
Frame1 first = new Frame1();
first.setVisible(true);
}
/*[B]now i have the first frame where i input the information[/B]*/
package albaestate;
public class Frame1 extends javax.swing.JFrame {
public Frame1() {
initComponents();
[Code] ....
What i need is to input the code so that in jLabel5 i get the text from jTextField1 in Frame1; in jLabel6 i need the text from jTextField2 also in Frame1; and in jLabel7 i want to display the calculation of what the jbutton1 in Frame1 is calculating.
I'd like to change the text on the two buttons which I have in my Dialog Box, how should I do this?
Also, when I click the X Button in the top right of the Dialog Box, nothing happens, and the program only stops when I end it in jGrasp. How do I make this button close the program when clicked on?
import javax.swing.*;
import java.util.Random;
public class SwingInputExample {
public static void main(String args[]) {

This is a part of my program. When the user enters "Exam Schedule" in the JtextField and clicks the add button I want the link to change to a link that opens a local pdf file. And if the user enters "Academic Calendar" the Jlabel will be set to another link. So far this works fine but the problem is that if you erase the textfield and enter another value the link of the previous value will still be there.
public void actionPerformed (ActionEvent e){
if (e.getSource ==add) {
if (text.getText().equalsIgnoreCase("Exam Schedule")){
link1.setText(text.getText());
link1.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
[Code] ....
What are a couple of examples to code a button that if it's clicked the panel's visibility is set to false?

I have two classes involved in this portion. CheckIn_Search
(class #1) is my main UI and I am collecting search information from the user in a jPanel form. When they click "Search" it passes the search criteria to a method that contacts a web service and gets the results. These results are passed to coSearchResults
(class #2) that opens a jFrame and jTable (in modal format, over the main window created by CheckIn_Search.
The user selects a row in the table and that selection data is passed back to coSearchResults to populate a new jPanel form. When the data is passed from coSearchResults, I want to close its window, hide the first jPanel in CheckIn_Search and make the second jPanel visible. To accomplish this, I created a method in CheckIn_Search that simply hides/shows the panels (it will do more later).
I instantiate and call the method in CoSearchResults as part of the button click event. The problem is, it doesn't work. The panels are unaffected and there are no errors. I've put in break-points and it goes into the method.. Here is the coSearch_Results code.
Here is am retrieving the jtable row id and using the first value in the row to get the data from the table model as there is more data than what is displayed in the table. I'm sending that whole row of data to the method that changes visibility.
private void btnOKActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_btnOKActionPerformed
// TODO add your handling code here:
int rowNum = jTable1.getSelectedRow();
String coNum = jTable1.getValueAt(rowNum,0).toString();
String[] text;

how to make this restart button work. This is what I have so far. I have put the restart button code in red and bold...
package Game;

make this button:
look more like this one:

I'm making a game of checkers for my A2 Computing coursework which is due in within a week. I have completely finished the game, and only thing I have left to do is connect the two JPanels together via a CardLayout that I have made. However I am unsure how to do so
Here is the code from my CardLayout:
import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JButton;

I have kept the code I am displaying to a minimal, hence I have removed all the action listeners for my buttons, anyway the problem I have is that, I would like it so that when the user clicks on the 'Multiplayer' button which is the array button ourButtons[1], it will then transition into my main game screen so that the user can then play a game of checkers.
Here is the main important GUI from my CheckerBoard class:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class CheckerBoard extends JPanel implements ActionListener, MouseListener {
// Main routine that opens an Applet that shows a CheckerBoard
public static void main(String[] args) {
new CLayout();
[Code] ....
Once again kept to a minimal.
Basically the class is supposed to have a static variable that keeps track of the number of companies (numberOfCompanies) that have been created and a static method that returns the value of this variable. I need to have a constructor and a method to addEmployee, a method to printCompany, and a toString method. The addEmployee method will check that there is only 1 salesperson, 2 designers, and 4 manufacturing persons at a time and will check that there are no more than 7 employees of the company.
The addEmployee method will return a String indicating what the error is (i.e. "There is already a sales person in this company") or a null if the employee was added. If attempting to name a third company, an error message will be shown. what i have so far but my print company mmethod returns null company class :in which i am obliged to use inputdialog because it says that it cannot return void when i use the showmeassage diaolog.
company class:
import java.util.ArrayList;
import javax.swing.JOptionPane;
public class Company {
private ArrayList<Employees> list ;
private static int numberOfCompanies;
[Code] ....
error message when print button is clicked:
Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: JOptionPane: parentComponent does not have a valid parent
at javax.swing.JOptionPane.createInternalFrame(Unknown Source)
at javax.swing.JOptionPane.showInternalOptionDialog(Unknown Source)

The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.
import java.awt.BorderLayout;
import java.awt.EventQueue;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

I can't seem to put a label on this code:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class number2 extends Frame {
int x = 0;
int y = 0;
public void run() {
addMouseListener(new mymouselistener());
[code]....
how would I put a label on it?
I am trying to add a label to my gui, i am using the following code but it is not showing.
contentPane = this.getContentPane();
contentPane.setBackground(Color.GREEN);
contentPane.setLayout(null);
JLabel greeting = new JLabel("hello");
greeting.setFont(new Font("SansSerif", Font.PLAIN, 18));
contentPane.add(greeting);
greeting.setVisible(true);
I have been playing around with a snippet I wrote to get the Label on a drive (below). It works fine for me (though I will take any constructive criticism). My question is whether the is a way to set the drive label, purely with Java. I know I could call command line, or even resort to using the Windows API
import java.util.List;
import java.io.File;
import java.util.Arrays;
