Set JLabel Text After JButton Press

May 12, 2015

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);

KeyListner Won't Work - Just Ignoring Key Press

Apr 5, 2014

Java Code:

package --.-----.game;

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.util.ArrayList;
import java.util.List;

public class InputHandler implements KeyListener{
public InputHandler(Game game) {
game.addKeyListener(this);

[Code] ....

I'm trying to figure out why this doesn't print "This works" if I press or release anything. It just ignores the keys that I press.

Does this class look right?

Swing/AWT/SWT :: Displaying Image On Button Press

Mar 22, 2014

I have been reading some java guides here [URL] .... and was trying to put a bit of what I have learnt into practice but am having some difficulty. Basically, using netbeans IDE I have created a new jFrameform so that I can place swing components in design mode. What I want to create isnt overly complicated but I just cant seem to get it. In design I have simply added a panel and a button. When I press the button I want to display an image I have located at:

/resources/images/numbers/1.png.

This is my code so far (most of it has been automatically generated from me adding things via design mode:

/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/

package test;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import javax.imageio.*;

[Code] ....

I assume I need something like below somewhere , do i need to create a draw method? if so how do I call it as it is expecting graphics2d as a parameter, what would I pass into it?

BufferedImage img = null;
try {
img = ImageIO.read(new File("/resources/images/numbers/1.png"));
} catch (IOException e) {
}

How To Update JLabel Or ImageIcon Anytime On Press A Button

Apr 15, 2014

I am trying to do a program about a contact agenda, now, I have one JPanel that contains three sub panels (GridLayout(1,3)) where I have in the left the picture of the Contact, the middle one is not important, but the right one contains 4 JTextFields with information of the contact and one JCheckBox that indicates if the contact is a favorite or not. The thing is that I am only able to show the first contact, but I want to be able to scroll between the contacts with a Button that I have in another panel. I think I am actually scrolling among the contacts, but the panel with the information from the contact is not updating the information...

public class PanelInfoContacto extends JPanel{

// -----------------------------------------------------------------
// Constructores
// -----------------------------------------------------------------
/**
* Construye el panel. <br/>
* @param contacto - es una referencia al contacto que muestra. contacto != null.
*/
public PanelInfoContacto(Contacto contacto){
setLayout(new GridLayout(1,3));

Going Through All The Keys On Keyboard One At A Time

Jul 14, 2014

I am writing a code that tries to figure out the users password by going through every possible key (brute force). Although I think its going to work, it looks EXTREMELY inefficient to me, since its just a huge switch statement for each character -- 94 total, including the shift values. Is there a built in method in the JAVA API that goes through every key or something?

Here is my code for that segment:

public char[] HackingPassword(){
char[] passChars = this.password.toCharArray();//convert the password to char[]
char[] hacking = new char[passChars.length];//make the hacking variable same size as users password
int nextCharValue = 0;//this is used to cycle through the keyboard
//check each letter of hacking to match with password
for(int i = 0; i < passChars.length; i++){

Reading The Name Of The File From The Keyboard

Feb 20, 2014

Write a program that extracts words from a file. For the purposes of this program, a word is defined as a series of adjacent letters. Only print words that are at least four and no more than 12 letters long. Print each word on a different line.

The program should read the name of the file from the keyboard.

************************************************** ************************************************** **************

I need to get the filename from the user for this particular program. Usually I would have the name of the file prewritten into the source code like this....

Scanner input = new Scanner(new File("gettsy_burg.txt");

I tried different ways but I just can't seem to figure it out.... I guess what I'm really asking is how to rearrange Scanner input = new Scanner(new File("gettsy_burg.txt"); since I want the user to input the filename instead of the filename being prewritten by the programmer(me).

This is what I have so far to let the user for input....

Scanner keys = new Scanner(System.in);
System.out.println("Enter the filename: ");
String fileName = keys.nextLine();
keys = new Scanner(new File(fileName));

How To Avoid Keyboard Auto-repeat

Oct 8, 2014

I wanted to make a small program to move a small rectangle by pressing the WASD keys. The program works, except that when I hold a key to move the rectangle, after a second, auto-repeat starts up, and the rectangle motion accelerates. I want to prevent automatic repeat to activate, so that the rectangle moves at a constant speed when I hold a key and stops when I released. Here is the ButtonMotion classe :

import java.awt.event.ActionEvent;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.AbstractAction;
import javax.swing.Action;
import javax.swing.JButton;
import javax.swing.KeyStroke;

How To Get Keyboard Input Without Focus On The Frame

Jan 29, 2015

so i'm working in a chat program and i'm trying to make it so that you are able to open another tab yet still be able to chat.

right now the client that the user download uses the keyadapter to get the keyboard input, but whenever the user un-focus the chat window, the keyadapter no longer gets the keyboard input.so is there another way i can get the keyboard input? so it doesn't matter what window you are focused on, you get the keyboard input either way?

Keyboard Class Is Not Configured Properly

Jul 4, 2014

package com.vesron.primes;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.MouseEvent;

[code]....

The parameter for the starting y is "fy" (Half of the screen). When I use the keys "z" and "x" it translates one pixel at a time left and right. That is good, but when I use the keys "a" and "s" it will double each time (good), but the starting y will drop significantly (bad). I tried manipulating the "x" and "fy" variables, but to no avail.
