Docs For Implementing ActionListener For A Gamepad / Joystick?
Mar 29, 2015
I'm rather new to java itself, but I've been writing C and C++ code for a while now even dealing with some x86 assembly language.
Java is a much higher level language and augments the hardware much more than I'm used to, but recently I decided to make a basic 2d platformer in java, my problem? Keyboards and platformers don't play nice, I have a DS4 controller sitting next to me and I want to use this. I've done some searching and I've found most people just using a library called "jinput" to use controllers, but I don't want to write anything that is dependent on a 3rd party libs. I want to rely only on what code I've written and the JRE itself.
Where I can find docs or even examples on listening for button presses, I don't need anything to map it, I don't even need to know how the analog sticks work (only going to use the control pad and X button anyway) I can do the rest myself if I just knew how to listen to the device!

Is there something special about this? I would think not, however all of the buttons in my application work except those with images.Here's an example of one:
Java Code: // Class #1
// All components defined as private initially, used in initComponents() later to build GUI
private JButton btnRock = new JButton();
/** Create the frame. **/
public GameView() {
initComponents(); // Initialize components
} // End of GameView Method
public void initComponents() {
// ROCK BUTTON
btnRock = (JButton) mainController.createIcon("rock");
btnRock.setForeground(new Color(0, 0, 0));
btnRock.setBounds(12, 34, 97, 67);
[code]....

public void paint(Graphics g) {
g2=(Graphics2D)g;
rectangle=new Rectangle(50,50,100,100);
}
public action() {
JFrame frame=new JFrame("Assignment 2");
frame.setSize(700,700);
frame.setVisible(true);
frame.setLocationRelativeTo(null);
[code]....
I'm trying to add shapes on my panel once a button is clicked.The tutorials I found is having only 1 panel & therefore they can use g.drawRect() directly but I have few panels & that's the part I don't know how to implement it.The coding above with (//invalid) is the part I would like to write it out but it's invalid.

I am trying to implement user input in my dice rolling program but I do not understand where I need to add the actionListener. What I want the program to do is allow the user to click on each roll button and have the output be between 1 and 6. I figured I can put it in the "main" class due to the size of the program but I would like to know the best way to go about adding the actionListener into a sub-class for practice purposes.Here is my code thus far:
package com.jprogs;
import java.awt.*;
import javax.swing.*;
public class DiceGenerator extends JFrame {
DiceRollEvent dice = new DiceRollEvent();
// create the roll buttons
JButton roll_1 = new JButton("Roll #1");
JButton roll_2 = new JButton("Roll #2");
JButton roll_3 = new JButton("Roll #3");
JButton roll_4 = new JButton("Roll #4");
JButton roll_5 = new JButton("Roll #5");
// create output field for each roll
[code].....

I am using the DJWebbrowser in a Java Swing Application that I am working on
// Browser addon as Panel
JPanel browser = new JPanel();
browser = (JPanel) util.BPanel.createContent();
wrapper.add(browser);
and am sending data from a Google Map API , Distance Matrix Query with following code
function callback(response, status) {
if (status != google.maps.DistanceMatrixStatus.OK) {
alert('Error was: ' + status);
} else {
var origins = response.originAddresses;
var destinations = response.destinationAddresses;
var outputDiv = document.getElementById('outputDiv');
[code]...
I haven't found a way to access a class property from the class that invoked the web browser, because the above WebBrowserAdapter is in an anonymous Inner Class.´I would like to have the distance that is sent from the Javascript to the application be passed on to the class member "distance" that in the invoking class.

I have a snippet here that I'm working with and I have a few questions about it.
button.addActionListener( new ActionListener(){
@Override
public void actionPerformed(ActionEvent ev){
System.out.println("Button Pressed");
}
});
My questions are:
1. How is it possible to use new on ActionListener when ActionListener is an Interface, not a Class. Isn't it illegal to instantiate an Interface?
2. What is going on with the argument to addActionListener? We have the new ActionListener, but we also have a method being defined as well?

How can I remove the ActionListener from the buttons of my application after i have got something happen.
Please consider the following application:
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Exer1218659 extends JFrame {
private String[] textButtons;
private Container contents;
[Code] .....
After the line 37 executes I expect that the ActionHandler (ah) will be removed from all of the buttons but this do not happen, then all the remaining button still responding to the clicks. Where is the problem in my code.

I was working on implementing the game Hunting the Wumpus [URL] .... for one of my projects in College. I've got the major parts of the game already implemented. I am working on creating a start screen right now. But I've run into a strange problem. In my code the main method that draws is the PaintComponent method in the private class HTWPanel. I need the Actionlistener to listen to the "QWES" keys while the state of the game is PlayState.Playing so that the user can enter the direction he's going in. If I have the following code for my paint component, the Actionlistener works fine.
public void paintComponent(Graphics g) {
super.paintComponent(g);
map.draw(g, 100);
}
But when I try to add a start screen (by changing the background color and adding a label called "StartScreen"), the controller only listens to keys while the start screen is showing, not while the game is playing. I'm pretty sure this problem is due to some internal implementation of KeyAdacpter or ActionListener, but I'm not sure what.
public void paintComponent(Graphics g) {
super.paintComponent(g);
if (state == PlayState.START) {
this.setBackground(Color.orange);
this.add(startScreen);
}
else if (state == PlayState.PLAYING) {
if (this.getBackground() != Color.WHITE) {this.setBackground(Color.WHITE);}
map.draw(g, 100);
}
I attached a screenshot of my main class, HuntTheWumpus, and a screenshot of what my game looks like so far. Each square is a different room in the Wumpus's lair. The black rectangles are door representing which direction you can go to. The rooms that are 2 squares or less from the wumpus are colored red. The hunter is represented by the black circle in the upper left hand square. His he can move left right up and down into different rooms with the "QWES" keys.

I've scanned the book and a few other forums trying to find an answer to my particular question (or I simply didn't understand) with no luck. I want to create an ActionListener for my ATM machine, that will both receive the input numbers to check them against the passcode for a predefined user, but also add the typical " * " that we see when performing such an action.
1. I have created individual objects for each button, which I then used in the constructor "perform" from class action. I'm not sure where to start in the method ActionPerformed.
2. How do I get the asterisks to appear in the JPasswordField each time a numeric button is pressed on the keypad?
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Atm extends JFrame {
Atm(){
super("ATM");
//Create Panels For ATM
JPanel buttonPanel1 = new JPanel(); //To Contain Digits 1-9
buttonPanel1.setLayout(new GridLayout(4,3));
[code]....

Ok, so I'm making a game with a space ship that flies around the universe and discovering new planets. It works fine so far, but I'm looking to make it perform better and be better compatible with lesser-processors.So, I'm trying to put in an FPS counter and an entirely new game loop so that my game can decide for me what FPS I should use.
I have two classes. Heres the big, main one: [Java] package cyentw.game.src; import java.awt.Color; import java.awt.Font; impor - Pastebin.com *I want to change the loop and put an FPS counter in around line 456, you can scroll past the rest if you'd like*And heres the init frame one, in case you'd like to see it for some reason.
Java Code:
package cyentw.game.src;
import javax.swing.JFrame;
public class Start extends JFrame{
public static JFrame frame;
public static int WIDTH = 500;
public static int HEIGHT = 500;
public Start() {
[code]....
how to make my game loop as quickly (or a bit slower) as it can, and my FPS is static.

I was suspecting I had a jButton not working, so I added a console print to test. See below. When I click the button, the console doesn't display anything. Am I using the button wrong?
private void jButtonUpdateItemsMouseClicked(java.awt.event.MouseEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}
I have also tried the following with the same results (or lack of).
private void jButtonUpdateMajorDeckItemsActionPerformed(java.awt.event.ActionEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}

is any simple way to apply the same code on both ActionListener and MouseListener, so that the same code is executed when the user either presses a JButton or presses Enter when a JTextField is focused.I know that I can define a method, while it is not preferred as I may use break; in my MouseListener.
A simple example:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TwoListener extends JFrame
{
[code]....
Although I can define a new method that prints out the three numbers, I have to add certain break; code in different cases. So I just wonder whether there is another way to do things like this.

If you look at line 74 you will see my actionPerformed method where I want to switch the icon displayed on the JButton. I know I still have to add the images to the button however I am running into a few issues here.
In my next class it will be vital that I can decipher what each icon is display on the JButton.
Java Code: import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
public class Screen implements ActionListener

I know that JMenu and JMenuItem is suppose to use action listeners but would you consider this implementation an exception?
menuAbout.addMouseListener (new MouseListener () {
@Override
public void mouseClicked (MouseEvent arg0) {
JOptionPane.showMessageDialog (null, "Server Tec Software System
}
@Override
public void mouseEntered (MouseEvent arg0) { }
@Override
public void mouseExited (MouseEvent arg0) { }
@Override
public void mousePressed (MouseEvent arg0) { }
@Override
public void mouseReleased (MouseEvent arg0) { }
});

So I have this issue with ActionListener, I have created JMenuItems in a loop and applied them to JMenu's. But now when I want to make an action listener for each button, I'm not sure how to select them individually as in the loop it's 1 object looped through different names.
Here is the way I made the menu.
package com.simbaorka101.te.gui;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import com.simbaorka101.te.reference.Reference;
public class Menu extends JMenuBar{
private static final long serialVersionUID = 3601135828398064405L;

Therefore my main question is, am I even approaching this problem correctly? In my next class it will be vital that I can decipher what each icon is display on the JButton. I am working on programing A* but I have to get everything talking first.
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
public class Screen implements ActionListener
