I have an application that reads through a ResultSet... while I'm reading that ResultSet, I am creating new JButtons..... Now I need to add an ActionListener to those JButtons...... but they are not visible to the actionPerformed method. So I thought I'd try to add an ActionListener as I created the buttons with the following code:
final File file = new File(rs.getString(3)); SKPictureButton spb = new SKPictureButton(url,file.getName()); spb.addActionListener ( new ActionListener() { public void actionPerformed( ActionEvent e )
[Code] ....
However this seems a bit excessive to me..... I don't think I really want to be creating a new ActionListener class for each JButton do I ? Is there a better way to make the JButtons created in this method visible to the actionPerformed method ? I'm just gettin' back into the "Swing" of things in Java.... haven't coded it for a while.
I am in the middle of creating a chess application, and am currently working on laying out a list of moves on the right of the actual board. Specifically, I want to have a JLabel that says "moves" on top of a JList that contains the moves, on top of two buttons, labeled "<" and ">" respectively, to which I will eventually add functionality to take back and un-take back moves. Currently I have the first two parts down, but when I add my buttons,the other components are getting messed up.
I have all of these things in a vertical BoxLayout inside of a JPanel with a fixed width of 70, and a height that varies according to the size of the window (I overrode the getPreferredSize method of the JPanel). The two buttons are within their own JPanel with a grid layout with one row and two columns. Then I basically just add the moves list label, the movesList, and the panel housing the buttons to the larger panel, in that order.
However, I am encountering two problems. One, the buttons display the text "... " instead of "<" and ">" as if there is not enough room, although I'm pretty sure three periods take up more space than one less than or more than sign. The next is that, without the buttons at the bottom, the label reading "moves" is appropriately centered (or left aligned, I can't tell which) over the movesList, and you can read its whole text. However, when I add in the buttons at the bottom, the label of the top shifts over to the right and then reads "mov..." because it has run out of room.
Here is my code:
//move list movesListLabel = new JLabel("Moves"); //the components for the actual movesList come from another class with an object called pen, but I don't think this is the problem listModel = pen.getListModel(); JList movesList = pen.getMovesList(); JScrollPane listScroller = pen.getMovesListScrollPane();
Am trying to dynamically insert buttons (which will be presenting card in a frame) using grid layout.As shown image is getting inserted but its not fit in button.I tried Darryl's Stretch icon as well but of no support.
I am trying to program the A star algorithm using JButtons. Now I have some tweaking to do but I have to get past the errors first.
I am getting the following errors:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at AStar.findEndButton(AStar.java:40) at Screen$1.actionPerformed(Screen.java:59) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2341)
[Code] ....
In my AStar class you will see these buttons which is an instance of matrixButtons
I'm having issues with JButtons and painting methods, whenever I click a grid on the board, the buttons in the JPanel disappear. Here is the board class:
package GUI; public class Board extends JPanel implements Observer { /** * */ // private static final long serialVersionUID = 1L; private final int boardSizeX; private final int boardSizeY; private final int L = 20;
[Code] ....
I know the code is messy in places, this will be fixed later, just need some pointers on how to solve the JButton issue.
I am making a program which will have the user enter their location (by postcode) into the GUI (Swing).
I want to use Google's Directions API [URL] .... to find directions from this user input address to another address. However, I have never gone about using external APIs before and even going as far as installing the necessary files on my system to get started is getting complicated.
How do I go about using this API in my own application? I have tried following the tutorials (e.g. [URL] .....) but I suspect I may even be using the wrong tutorial (I am seeing references saying that the client thing is depreciated).
import java.awt.Color; import java.awt.GridLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.*; public class Screen implements ActionListener { public JButton[][] b=new JButton[200][200];

I am in the process of creating a Tic Tac Toe game with a GUI using JButtons that will hold the X and O pictures. I have the picture appearing when i click it once but it jumbles up all the other buttons which is why i have to run the method resetAllButton() to set everything back. Once i click the x again it puts everything back how it is supposed to be and works normal. How can i get this to work in one click.

I am designing/coding a blackjack GUI program and I'm trying to add function to my JButtons. Problem is, I now have 2 NullPointerExceptions.
public class GameConsole { Player user; Player dealer; Deck playingDeck; ValidateInput validate = new ValidateInput();
[Code] .....
I am trying to do. I am getting the following exception/stack trace at line 14 in userTurn()
Exception in thread "main" java.lang.NullPointerException at blackjackControls.GameConsole.userTurn(GameConsole.java:163) at blackjackControls.GameConsole.gamePlay(GameConsole.java:87) at blackjackControls.Main.main(Main.java:7)
and then the program continues and after I click the button I get :
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at blackjackControls.GameConsole.userTurn(GameConsole.java:163) at blackjackControls.ResultPanel$1.actionPerformed(ResultPanel.java:34) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2028) //and then about 30 more "at" lines
Why am I getting these exceptions and how do I fix it?
I am trying to create a code which allows the users to create JButtons to a an existing frame.So what I want is that users can create buttons wihch opens a URL. The user need to be able to click on an Existing JButton called "Add Favorite", insert the name of the favorite and URL and the button is added with the functionality to open the URL in Internet Explorer.
I already have a beginning but have no clue how to add that functionaly to create JButton by pressing on button "Add Favorites" with the needed functionality The functionality needes to be added to Button4 ("add Favorite" ). As you can see, Button4 ("add Favorite") opens two inputShowDialog which allows the users to insert the name of the favorite and URL.
import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.JButton.*; import java.awt.Dimension.*; import java.lang.RuntimeException.*; import javax.swing.JOptionPane; public class Favorites extends JFrame implements ActionListener{ //private JPanel panel1 = new Jpanel ("Add Favorite");
I have to implement a face that smiles and frowns. I figured the easiest way to do this was to use JButtons. I also can't close the applet without hitting "end program". I was given a bit of code and had to add onto it. Here's what I have so far.
import java.awt.event.ActionListener; import java.awt.event.ActionEvent; import java.awt.BorderLayout; import java.awt.Graphics; import java.awt.Color; import javax.swing.*; public class AnimationFace extends JFrame { public static final int WINDOW_WIDTH = 400; public static final int WINDOW_HEIGHT = 400;
[Code] .....
It's 90% done but once I changed the face from smile to frown, it lost an eyeball.

I'm creating a program that will compile and run another java program:Lets say I have a program in directory
D:HelloWorldsrc and compiled program will be in D:HelloWorldin inside src and bin is a folder hello (that's a package)
package hello; public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World"); System.out.println("Hello World"); } }
This program will be run by another program (that's the program that I am creating).Here is the code of my program:
package runnercompiler; import java.io.IOException; import java.io.InputStream; import java.util.logging.Level; import java.util.logging.Logger; public final class RunnerCompiler {
I cannot get my panels to appear in my GUI when I run my program. There is probably a really simple fix for this but it is taking me hours. This program is a working progress and I have just included two classes out of five. That should be adequate to diag my problem.

I have a practice exercise here wherein I will add a JOptionPane to a program. When the close button is clicked, the JOptionPane will appear asking the user to exit the program. If the user clicks "Yes," it'll, of course, close the entire program and not just the JOptionPane, but if the user clicks "No," it will return to the program. Please refer to my code below:
try { output = new DataOutputStream(new FileOutputStream("ProjSixExe4.dat")); } catch(IOException ex) { this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING)) } final JOptionPane optionpane = new JOptionPane("Are you sure you want to quit this program?", JOptionPane.QUESTION_MESSAGE, JOptionPane.YES_NO_OPTION); this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
The exercise said it must be placed before the EXIT_ON_CLOSE portion.
I'm writing a Java Swing program for my software development class to allow a user to create a map for a side scroller video game. I'm stuck on a particular part of my GUI where I'm trying to create a properties box for specific tiles. When I draw the components onto the JPanel and display it as it is, it shows two check boxes per row. On the ScrollPane however, all the check boxes go straight onto one line and draw out the scroll pane. Right now I am only concerned with just making the basic GUI.
Here is what I have so far:
Within the main class, I am creating the JFrame and adding components to it. I am attempting to create a JScrollPane which will hold the properties check boxes...
Here is the method where I am implementing the code. It works, but it doesn't display correctly.
private void createPropertiesBox() { PropertiesBoxPanel pbp = new PropertiesBoxPanel(); propertiesBox = new JScrollPane(pbp); propertiesBox.setViewportView(pbp); frame.add(propertiesBox);

I've been tinkering with this code for quite some time now and I cannot seem to make a breakthrough on how to fix this.
I want to develop a Java program that uses OpenScript APIs to test my applications. The OpenScript framework automatically creates the Java Code so I was thinking of either using this code or create my own using the APIs.
I tried both options using NetBeans but I'm getting errors everywhere starting with the library import. I'm pretty new to Java so I'm sure I'm missing a lot of things here. I pasted the code below from the OpenScript framework that want to use in a stand-alone file for your reference.,
