I'm using Eclipse with the Window Builder Pro plugin to create a Java program. I noticed that when I had Eclipse create an action listener for a combobox in a Swing GUI it created an AWT listener.
Did I choose the wrong type of listener? I want my code to use the Swing components because I understand that they are more portable.
In my code 0,1,2 work fine an present my prompts an use my listener correctly but for some reason 3-6 is not an I don't know why? Here's my attached code.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

I meant 3-5 not 6
I have three JComboBoxes. When the user selects an entry in the first JComboBox the entries in the second are set. For this I use an Action extends AbstractAction which is bound to the first JComboBox.
I have also bound an Action to the second JComboBox.
Problem: this also fires when the entries on the second JCombox are added which leads to a Nullpointer.
I need a Listener which only reacts to user input, and does not react when the model of the JComboBox is changed.
I'm not a java developer, i'm a tester. I am currently testing a java swing application and to do that I have to automate how its used. IE I have to write code which will press buttons for me rather than depending on an end user to do this. I have managed to reverse engineer the entire application (hooray for me), however I am struggling to work out how to invoke methods that would typically be kicked off by a user pressing a button. how to I can call actionPerformed(ActionEvent ae) method which sits in the ATMMainPanel class?
I will be calling it from inside another method which is the equivalent of the main() method.
Java Code:
public class ATMMainPanel extends JPanel implements ActionListener {
[declarations here]
//here - User is pressing the Enter button after putting in pin.
public void actionPerformed(ActionEvent ae) {
[code performed when button is pressed]
} mh_sh_highlight_all('java');
I have buttons created on a frame and then I register the listener from a controller in a controller-view relationship.
When I click the button on the face, the action never executes for some reason. I thought maybe there was a problem registering the listener but I can call the buttons doclick() method and it executes as it should. Perhaps I'm overlooking something really obvious here but I can't see it.
btnEight = new JButton( "8" );
// btnEight.addActionListener( controller );
btnEight.setBounds( 212, 90, 41, 23 );
frame.getContentPane().add( btnEight );
and then I add the listener
public void setController( ActionListener theController ) {
Component[] components = frame.getContentPane().getComponents();
for ( Component component : components ) {
if ( component instanceof JButton ) {
JButton button = ( JButton ) component;
button.addActionListener( theController );
}
}
again, when i click the button nothing happens. but if i add the following code
btnEight.doclick()
the actionPerformed invokes in theController as I intended.
You can see the entire project on GitHub so you can see the full context. The controller class contains the listener and the view class contains the buttons.
I am working on a 3D-Projekt, but that's not the point. I wanted to call a function to turn the camera and want, that the function ist called while the key is pressed. I tried following:
private ActionListener actionListener = new ActionListener() {
public void onAction(String name, boolean pressed, float tpf)
if (name.equals("Camera Left") && pressed) {
setViewAngle(-1);
I think, I have to change the ActionListener "onAction", but I can't remember in which way. In the actual code the programm only once perform the action when the key is pressed.
I already tried :
while(pressed) {setViewAngle(-1)}
But that didn't work, but get the whole programm to halt.
So I thought of key repeating.
I'm writing a program for exemplary reasons that is basically two text fields, one for a username, and one for a password. the way its written is asking testing for what is inputed into the text fields if its equal to a "valid" username and password. if it is, a variable representing that is set equal to 1. there is another if statement asking if the actionevent.getsource is equal to the name of the textfield. the issue I had was that when I ran the program, it seemed to only test for the first condition, so I got the same result from the program regardless of what I input into the text field.
The Code
Main class:
import javax.swing.JFrame;
public class Alpha {
public static void main(String args[]){
log l = new log();
l.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
l.setSize(360, 240);
l.setVisible(true);
[Code] .....
The code originaly was written "eve.getSource() ==" but I changed that to see if it would resolve the issue with no avail. With it written this way, the program does nothing upon entering the text and pressing enter. Currently, there is nothing written to change the variable "val" to 1 to show that the username is valid. I did this because I can't figure out how I would go about doing this.
here is the code i already have made;
import java.awt.*;
import javax.swing.*;
public class EX_7_2 extends JFrame
{
public EX_7_2()
{
setLayout(new BorderLayout(5, 10));

I have panel = window(new frame) and its used to render a video image on, i need to pickup a touchscreen press change of event but not sure which event listener to use and on which component. Is it a panel, window or frame event? and which listener would detect a focus change or a mouse press
I know mouse listener and focus listener and window listeners are available but not sure they would be able to detect the screen press on the video rendered image...
This is my first servlet program. I wanted to try a web application where "register" user module will be in servlet program.I can access my index.jsp but when I enter values and click submit.
I get "There is no Action mapped for namespace [/] and action name [RegisterUserServlet] associated with context path [/TrainingApplication]. - [unknown location]".
Here's my index.jsp file:

I am using apache-tomcat-8.0.14 server.
When i click on the button from bottom panel, top panel need to be redrawn. But redrawing is not happening. It happens only when resizing the applet.
public class Graphics_Chart(){

JScrollPane topPane = new JScrollPane(new ImagePanel2());
topPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
topPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_NEVER);

I have two(panel1 and panel2) panels in a jframe,all three of them are different classes .
In jframe there is a display panel on which the panel1 and panel2 are called and displayed.
now i have a button in panel1 .i want that when i will click on that button panel2 will be displayed or added to the dispalypanel of jframe.
I am making an MVC program and I am not allowed to put the action listeners in the view class. I was able to get one button working fine but since I am unable to reference them I cannot give them both individual responses.

My output is all over the place. I cancelled out the borderlayouts beneath each panel I created and it completely changed the output, and I'm not sure why. The first photo below, shows what it looked like with the layouts and the second shows the output without. I still don't understand why I don't see the digits 1-9.
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionListener;
public class Atm extends JFrame {
Atm(){
super("ATM");
//Create Panels For ATM
JPanel buttonPanel1 = new JPanel(); //To Contain Digits 1-9
[Code] ....
Why would setting the layout beneath each object change the layout so much? I stayed consistent in my use of BLayout and GLayout in the program.
this is the first code
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
public class ChickenListener implements ActionListener {
int loopctrl;
static Connection cn;
static Statement st;
static ResultSet rs;
static PreparedStatement ps;
[Code]...
the second code
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
public class QuantityCounterListener implements ActionListener {
String tempStrng;
int tempInt;
int x = 0;
[Code]...
what my problem is i need to transfer what does "tempString" from code 1 holds to code 2 in the //x part in the prepared statement.
So im making a calculator just basic 4 function with a clear button. as i am working into this project i am running into an issue of assigning which click sets what. For instance i click the two button how do i tell it to assign it to firstNum, versus secondNum?
private class theHandler implements ActionListener{
public void actionPerformed(ActionEvent event){
if(event.getSource()==one){
firstNum=1;
}
if(event.getSource()==two){
secondNum =2;
}
if(event.getSource()==three){
secondNum =3;
}
So this for instance allows me to set one to the firstNum and then add it to two or three but im not sure what to do next. I have in my mind i want to do something like make three listener classes, that operate in sequential order like you pick the first numbers, click an operation, and then select the second numbers then hit the operation(equal) button to display answer. Am i on the right track or what?
I have developed a web portal using jsp and struts 2. I have approximately 10 JSP pages which looks exactly the same and have two text areas and two hidden fields. All 10 pages are exactly the same except for hidden field value. Can't i have a single common jsp page. How can i achieve it. A sample page i am attaching...
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ page pageEncoding="UTF-8"%>
<%@ page language="java"%>
[Code]....
As this is an Assignment page so hidden field value is assignment. If the page is OBJECTIVEs then value will be OBJECTIVE.
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;

If I have the next request scoped JSF bean for example:
public class UserBean {
private String name;
private String surname;
public String saveUser(){
//service is called to save a user
}
public String updateUser(){
//service is called to update a user
[Code] ....
1.In struts for example the Action classes are singletons and I think is the way it has to be because they contain business logic and is the same logic for every user but in JSF because of you mix properties from a form and methods with business logic, these beans have to be request scoped like the above one but is very wierd that a bean which contains business logic(saveUser()....) be request scoped;I dont see it effective, is like creating a new servlet each time you want to save a user but I think is the way JSF works, right?
2 To avoid the mixing of form properties in a bean with business logic, some people say to have the form beans request scoped and actions beans session scoped.
- Is this right?
- How then can you get the request form bean in the action bean?
- The scopes in JSF are request, session and view so you cannot create singleton action beans, the best you can get is a session action bean, right?. Once again I dont see the point of creating action beans with session scoped,they should be application scoped if it existed
Is it possible to define the same message driven bean as a listener to different queues?
The goal being to define different redelivery configuration for different kind of messages, but handle them all through a single deployment MDB for unity/entity purposes.
The other option is to have many MDBs targeted to the same source code.

I want to make a program that will move a square to the left if you press "a", and to the right if you press "d". (Once I know how to do this I can figure out W and S for up and down by myself). What code would I use for doing that? Here is the program I have now. I used the oracle tutorial but it just shows how to handle for if ANY key is pressed.
This is what I used How to Write a Key Listener (The Java Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
Java Code:
import java.awt.BorderLayout;
import java.awt.Graphics;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class myGame extends JComponent {
public int x = 20;
public int y = 20;
