Swing/AWT/SWT :: Making JButton That Switches Text From 2 JTextFields On Click With Mouse
Aug 6, 2014
I have made a window using JFrame and on my JPanel I have added 3 components: 2 JTextFields ("field1" and "field2") and inbetween them a JButton ("switch"). My goal is to switch the value of field1 to field2 and vice versa when the JButton is clicked. I thought this ActionListener which I have added to my JButton would achieve my goal:
public void actionPerformed(ActionEvent e) {
field2.setText(field1.getText());
field1.setText(field2.getText());
}
However, it changes the value of field2 into the value of field1 but not the other way around.

I've got the game working just fine, but I don't like the way it starts playing the second you hit the "Run Last Class" button in Eclipse, and would really like to have the game start, then wait for the user to click a button before running the core WHILE loop. Everything is implemented in a single class, and here is the playGame method that starts the ball moving:
private void playGame(){
while (!gameover){
moveBall();
checkForCollisions();
}
All I want to do is pause before the WHILE loop until the users clicks the mouse button, nothing fancier than that! I've done quite a bit of reading, and it looks like ActionEvent may be the way to go, but I'm not clear on how to use it correctly in this scenario.

In the method mouseClicked(MouseEvent me) the co-ords of the click are obtained.
* if they are within the confines of the rectangle rect, console output System.out.println("inside box") is displayed
* in either case the click co-ords are displayed in the console
I'm getting the co-ords of the mouse clicks but no message when the click is inside the box
import java.awt.*;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
/*
Experiment 04 was successful. So now (Experiment 05) I must try and see if I can identify mouse clicks that occur within the rectangle.
*/
public class AFrame extends Frame implements MouseListener {
ARectangle rect;
public AFrame(ARectangle rect) {

I am relatively new to java. . I cannot...(actually do not know) how to change the actionlistener (actionPerformed) after the second click in an array of JButtons. This is how the program performs right now.
On the 1st click on the grid, the border of the button clicked will change to 'blue' and another button will change its boarder to 'red'. on the next click the same action is performed.
What I need is to change action when the 'red' bordered button is clicked, lets say change the color of the buttons from the 'red' to the 'blue' buttons.(x 3 buttons).
The logic about how to perform the final result I think I can do on my own but my problem is how to change the action when the red bordered button is clicked.
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.BorderFactory;

I am trying to plot a graph and graph should display when JButton is clicked. To create data set, I am taking some value through JTextField and then created a chart and plotted it. I've got a problems: the chart doesn't refresh/update when I change the text field value.
public class Test2 extends JFrame {
/**

private static final long serialVersionUID = 1L;

In JButton's click event, I wanto to show a JPanel to print the message "Processing" on the screen. Before JButton's click logic end, hide the JPanel.
Actually, JPanel is not displayed. I do not know why.When msgPanel .setVisible(false); is commented out, JPanel is normally displayed .But do not know how to hide it when JButton's click logic is finished.
Here is the code.
loadBtn.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
JPanel msgPanel = new JPanel(rootFrame);
// Show the message JPanel

Just run the following code and move the mouse next to the text of the button and you will see exactly what I am talking about. Any way to prevent this continuous flash?

public class GUI {
public static void main (String[] args) {
javax.swing.JFrame frame = new javax.swing.JFrame();
javax.swing.JPanel panel = new javax.swing.JPanel();

I'm creating a program to animate Button.
When Mouse is moved on JButton the Button slowly disappears and when the mouse is moved away from the Button it appears again.
Every thing is working fine except an error which i can't understand.
Java Code:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class AnimatedButton{
private JFrame frame= new JFrame("Animated Button");
private Animate b1= new Animate("OKAY");
float initialAlpha;
Timer t;
float incrementAlpha = -.03f;

The error is:

I am having trouble with a mouse click method. In short I have a hexagon grid, and every time I want to click on one particular hexagon I want the color of the hexagon to change to blue(by default the color is grey). This part works, but when I go to click on another hexagon I want the color of the previous hexagon to change back to grey while at the same time changing the color of the current hexagon clicked to blue. So in other words, I only want one hexagon blue at a time. How might I do this?
I have a hexagon class for one particular hexagon, and a hexmap class for multiple hexagons. I know I should probably be handling mouse clicks in the hexmap since it deals with the whole thing. But I cannot say something like hexagon.setColor within a mouselistener in that class(it gives me a lot of issues). Here is some of my code :
public class Hexagons()
public Hexagons(HexMap theMap, int mapRow, int mapCol, int width, int height) {
this.map = theMap;
this.row = mapRow;
this.col = mapCol;
this.width = width;
this.height = height;

I have an ArrayList of JTextFields in a CAMSetup1 class that contains a bunch of named JTextFields: Layer_textField_1, Layer_textField_2, Layer_textField_3, ... etc
I would like to check the .isEnabled status of a particular JTextField in that ArrayList from my main class by passing the name of the JTextField to a method in the CAMSetup1 class as a string
The peice of code calling the method from the main class is something like this:
if (CAMSetup1.getFieldEnabledStatus("Layer_textField_1") == true) {
data.writeToFile(CAMSetup1.getFieldText("Layer_textField_2") + " LAYER 2 LIST FILE
");
}
The method for checking the .isEnabled that I have so far is:
public boolean getFieldEnabledStatus(String textFieldname) {
boolean status = false;
//<need code here>
return status;
}
I also need getting the text:
public String getFieldText(String textFieldname) {
String filename = false;
//<need code here>
return filename;
}

Code given below does real time validation for 2 JTextFields. While entering some values to txt1 and txt2 enables the save button and removing values from txt2 or txt1 reset the save button to disable. I use Netbeans as IDE.What I want to do is, enable Save button after checking multiple JTextFields for validity. If any of the text fields is empty, btnSave must be disabled.This program gives expected result up to some extent. But there is little issue. After form appears for the first time, When I type something on Textfield1, Save button enables without checking Textfield2. This happens only at the first time.
public class NewJFrame extends javax.swing.JFrame {
private Boolean isValidFromTextField1 = true;
private Boolean isValidFromTextField2 = true;
public NewJFrame() {
initComponents();
btnSave.setEnabled(false);

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);

So, Once again I'm attempting to make a Who Wants to Be a Millionaire GUI game. This is the actual game screen code
package WWTBAM;
import java.awt.BorderLayout;
public class GUIGame extends JFrame implements ActionListener {
public static int moves = 0;
public static boolean finished = false;
public static boolean correct = true;
[Code] ....
When ever try and change the buttons text outside of the actual GUIGame constructor i can't. Like in the main method or the action listener.
The code won't work if you copy paste because it's a part of a larger package.

In my application, some text should be added to a text area in response to a click on a button. So as an action listener to this class, I made another class which implements the ActionListener.
Inside this class, I have obtained the text which I want to be added to the text area. But the text area is in another class and for the action listener I wrote another class.
Now the problem is that when I try to add the text to the text area by the following line of code, it says that textArea_1 can not be resolved or is not a field.
Java Code:
ParentPanel.textArea_1.setText("Name:"+ncrarray[0]+"
Code:"+ncrarray[1]+"
Rank:"+ncrarray[2]); mh_sh_highlight_all('java'); What should I do about it?
Even if I try to write a method like the following in the class in which the text area is created, it gives the same error.
Java Code:
public void printTextArea(String text) {
textArea_1.setText(text);
} mh_sh_highlight_all('java');
The text area is present inside a constructor of the class. I am writing the method outside the constructor (ofcourse).

I have a button that bolds all the text in the main div. I am trying to get it to change back to the normal text after it has been bolded. But I cant figure it out. It bolds the text and changes button value when button value is "Bold", but when button value "UnBold" and user clicks button the text does not unbold. Here is my function.
function boldDiv()
{
var button = document.getElementById("firstbtn");
var oldHtml = document.getElementById('main').innerHTML;

So, Iv'e been trying to make a simple Text Based RPG with Java, and it is going quite well, and my friends want to play it too but they aren't very tech savvy, so it's hard to tell them to get an IDE or use the CMD, so I wanted to know if there was a way to make my text-based game into a window, like using JFrame or something. All i need is a window that displays the text, and a bar on the bottom that lets the user input what they want (Kind of like a CMD).
I want it sort of like this window: This Pic

I'm running the code below which compiles ok using latest version of Java and on Sublime. The problem when it complies the output screen is blank and I can only see the text by adjusting the size of the box with my mouse - and then it colours in black. Code and screenshot below.
