Set JLabel Text After JButton Press
May 12, 2015I 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);

Oct 14, 2014We are creating a quiz as a school program, we are using netbeans and we have a little problem. The problem is that our JButton opens a new JFrame in a new window and we want it to stay in the same window. The code we are using is:
private void PlayButtonActionPerformed(java.awt.event.ActionEve nt evt) {
Question1 s = new Question1 ();
s.setVisible(true);
}
Is it possible to make it stay in the same window?

KeyListner Won't Work - Just Ignoring Key Press
Apr 5, 2014Java 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);

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, 2014I 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) {

Apr 15, 2014I 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{
// -----------------------------------------------------------------

/**

View Replies View RelatedSetting Image Icon And Closing Up A Game
Jan 23, 2014I recently made a game. But, I want to package it and give it to my friends. I know that I can create a jar of it and add the images to the folder, but what I would absolutely love is for it to just be a picture with the game name and click to run. The second thing is to replace that java icon to an icon of my preference, which I have been told numerous times to do with
frame.setIconImage(Image image)
which does not work for me.
Swing/AWT/SWT :: Closing Another Application Using Java Code

Opening And Closing Multiple Files In While Loop
Feb 7, 2014I'm going through a file (MySQL dump) and I wish to take the SQL and create individual files for each table (as opposed to what I do now, which is just run through the whole thing).
<code>
BufferedReader myDumpfileReader = new BufferedReader(new FileReader(tfDumpfile.getText())); BufferedWriter myDumpfileWriter = new BufferedWriter(new FileWriter("/users/linehanp/mydb/bin/tgac_dump/Vanilla.sql"));
while((dumpFileLine = myDumpfileReader.readLine()) != null){ DoStuff();
MyDumfileWriter.write("Whatever");
}
myDumpfileReader.close();myDumpfileWriter.close();
</code>
Now, this all works fine - but what I want to do is create a separate .sql file for each table.
However, I can't figure out the best way to do this - how do I create a new FileWriter (or instance of whatever class is required) as I'm going through the while loop? That or pointing the same one to different files as I go through the loop.
It can be assumed that the file may exceed RAM - I want to do it line by line rather than slurping the entire file as a string and "cheating" that way.
There appear to be many (a bewildering amount of) I/O options and I'm just unsure.
Closing Old Pop Up Frame With Existing Action Button
May 27, 2015I am modifying existing code to display graph after pressing calculate button. The graph pop ups in new controller/window. The pop up disappears after closing the application entirely. However I have trouble figuring out if it is possible to close that old/previous pop up and new pop up appears when calculate button is pressed again. Or at least reuse the pop up to display a new graph.
public class AdamCalculationApp extends AbstractCalculation {
/**
* Does a calculation.
*/
public void calculate() { // Does a calculation
control.println("Adam Calculation button pressed.");
double k = control.getDouble("k value"); // String must match argument of setValue
control.println("k*k = "+(k*k));
control.println("random = "+Math.random());

Threads Stuck On Closing Brace Of While Loop
Apr 14, 2014While analyzing the thread dumps for a performance issue in our java ee web application, I see many thread dumps stuck on a closing brace of a while loop. Here is the code block of a third party library bitronix (version 1.3.3 SNAPSHOT)
public XAResourceHolderState findXAResourceHolderState(XAResource xaResource) throws BitronixSystemException {
Iterator it = resources.iterator();
while (it.hasNext()) {
XAResourceHolderState xaResourceHolderState = (XAResourceHolderState) it.next();
if (xaResourceHolderState.getXAResource() == xaResource)
return xaResourceHolderState;
}
return null;
}
The thread dumps indicate that many threads are stuck in RUNNABLE state on line number 07. What could be the possible reasons on why a thread could get stuck on a closing brace of a while loop? The iterator of the while loop is a custom implementation.
JavaFX 2.0 :: Abnormally Closing A Dialog With No Buttons

I show the dialog and try to click the close window button on the dialogs title bar, and the dialog does not close!

How can I abnormally close a dialog with no buttons?
