Swing/AWT/SWT :: Alternative To Making Static JList?
Sep 16, 2014I am currently writing a chess application in Java swing. For the GUI part, I have one MainWindow class, and one ChessBoard class. The MainWindow has a main panel, in which is contained 1) a panel containing the chessboard from the chessboard class (a grid layout array of 64 JLabels), 2) a JLabel status bar, and 3) a JList to hold the moves of the game. I have a movePiece method in the chessboard class, which I would like to add the move and question to the moves list, which is contained in the main window class.
However, since JList is some special type, I can't make it static ( that gives me an error ). I also tried creating a method in the main window class to add a move to the list, which I would then access via the chessboard class. However, I can't make the method static, because it is referencing a non-static variable ( the JList ), and since the Main window class already has an object of the chessboard class, trying to create a main window object in the chessboard class creates a stack overflow error.
Swing/AWT/SWT :: Making GUI Application Design Extensible
May 5, 2015I have to create a Swing application for which i haved a set of requirements as,
1. there will be two JPanels ,left and right, on the main JFrame , left frame would contain a JTextField and a submit JButton ,user can enter values 1,2,3 ,in the JTextField and presses the JButton
a. if user enters 1, a JTextField will be shown on right JPanel
b. if user enters 2, a JTextField and a JRadioButton will be shown on right JPanel
c. if user enters 3, a JTextField and a JComboBox will be shown on right JPanel
So I have done that but when my boss sees the code behind this application he told me to make it more extensible i.e. if there is going to be an additional requirement for values 4 or 5 or 6 and so on , then i have to make minimal changes in my code or no change in my code and it should work . how this can be done ? is it possible make such software design ?
public class DesktopApp extends JFrame {
private static final long serialVersionUID = 1L;
private static final Logger logger = Logger.getLogger(DesktopApp.class);
private JPanel jp, jp2, mainPanel;
private JLabel jl, jl1, jl2, jl3, jl4, jl5;
private JTextField jText, jText2, jText3, jText4;
[Code] ....
What wrong am i doing here in this code which in not considered to be an extensible design ?
Swing/AWT/SWT :: Making Ball Bounce Around A Screen
Aug 12, 2014I've got to make a ball bounce around a screen.... From what I can gather they seem to hold back useful java code.
anyway, i've changed the code over and over, and think this is the most succinct way i can manage it. but i have a problem. where i've marked the code (*****) and the following line are conditional on each other. so one won't provide the correct answer without the other line executing first, and vice versa (ignore the code after, i haven't looked at where that should be yet ). Anyway I don't really want to rip the code apart, again, because i'm pretty sure it's close.
Swing/AWT/SWT :: Making Interface - Exception Group Layout
Sep 24, 2014I am making an expert system using Jess about animals. I wanted to make an interface using Swing and so I did. I have a problem using group layouts. The application works fine but at the end a exceptions is thrown:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: javax.swing.JLabel[,0,0,0x0,invalid,alignmentX=0.0,
alignmentY=0.0,border=,flags=8388608,maximumSize=,minimumSize=,
preferredSize=,defaultIcon=,disabledIcon=,horizontalAlignment=LEADING,
horizontalTextPosition=TRAILING,iconTextGap=4,labelFor=,
text=The animal is a cheetah.,verticalAlignment=CENTER,
verticalTextPosition=CENTER] is not attached to a horizontal group
[Code] ....
The application ask the user some questions about the animal. When the expert system has enough information to know the animal it tells the name of the animal and shows a picture of it. The exception is thrown when the application has guessed the animal and shows the response.
Here is the code:
package xindria;
import javax.imageio.ImageIO;
import javax.swing.*;
import javax.swing.GroupLayout.SequentialGroup;
import java.awt.*;
import java.awt.event.ActionEvent;
[Code] .....
I think the problem is related to the group layouts. I will attach the eclipse project too...
Swing/AWT/SWT :: Making A Custom Cell Renderer Work In A JTable?
Jan 24, 2014Now my issue is I have a JTable. The first column will contain Date objects all the way to the bottom. I want the JTable to display only the month and year. I created a custom cell renderer, but it appears the cell renderer method "getTableCellRendererComponent" is never called. (I tested it using System.out.println();) Here is my code for setting the cell renderer and the contents of the first column:
MonthYearTableCellRenderer renderer = new MonthYearTableCellRenderer();
tblView.setDefaultRenderer(Date.class, renderer);
for(int i = 0; i < 60; i++){
Calendar cal = Calendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 1);
cal.add(Calendar.MONTH, i);
tableModel.setValueAt(cal.getTime(), i, 0);
}
The Date objects are set into the cells of column 0 correctly. The table shows the result of the "toString()" method for each cell in that column.
Swing/AWT/SWT :: Making Two JComboboxes To Be In Sync When One Selects Item From Dropdownlist?
Jan 17, 2015basically I would like to know how to to the following Java. Example... Say I have one JComboBox, and it is populated with 10 items which reads from a text file ("apple","banana","kiwi","orange","grape fruit"), and the other JComboBox holds the price ($1,$2,$4, etc etc...you get the drift).
How do I make in such a way when I select for example banana from the JCombobox that it syncs the other JCombox to the correct price?
Basically syncing the two JCombobox so that you do not need to select the price yourself - it does it automatically for you.

Swing/AWT/SWT :: Making JButton That Switches Text From 2 JTextFields On Click With Mouse
Aug 6, 2014I have made a window using JFrame and on my JPanel I have added 3 components: 2 JTextFields ("field1" and "field2") and inbetween them a JButton ("switch"). My goal is to switch the value of field1 to field2 and vice versa when the JButton is clicked. I thought this ActionListener which I have added to my JButton would achieve my goal:
public void actionPerformed(ActionEvent e) {
field2.setText(field1.getText());
field1.setText(field2.getText());
}
However, it changes the value of field2 into the value of field1 but not the other way around.
Simplify Two Large Methods Into One Similar Method?
Jan 4, 2015Right now I have 12 methods, each roughly 40 lines long, and I am contemplating whether I should simplify some of the pairs (12 methods, but every other method is very similar to each other, so 6 pairs) into one method.
The main pro of simplifying them is that my class will be much smaller, right now its about 555 lines of code. However a con is that it might not be as straight forward, at first glance at least.
Here is what I am talking about. Two original methods that are very similar:
void rotateRightClockwise(int rotations){//rotates FRONTS's RIGHT! CONFIRMED
String a, b, c;//temp values
for(int i = 1; i <= rotations; i++){//confirmed
a = cube.cube[1][2].square[2];//3
b = cube.cube[1][2].square[5];//6
c = cube.cube[1][2].square[8];//9
[Code] ....
The only difference between these two methods, other than the last chunk for each method, is the I have to change the 2nd square bracket, [], values from lines 9-23 for cube[][]. That's it. So I am thinking of combining them into something like this...
private void rotateRight(int rotations, int x, int y){
String a, b, c;//temp values
for(int i = 1; i <= rotations; i++){//confirmed
a = cube.cube[1][2].square[2];//3
b = cube.cube[1][2].square[5];//6
c = cube.cube[1][2].square[8];//9
[Code] .....
And then after calling this similar method, I would finish off the last chunk from each methods, since they are too different (ie lines 26-38).
The reason why I ask this is because I am trying to build up my portfolio and I want to know if the employer would look at this and say "that was a good move by compacting your code" or "this is not that straight forward".

The error I am getting is "Type mismatch: cannot convert T to T"

double num2 = in.nextDouble();
String s = "";

Making A Window For Java Text Based Game
Jan 10, 2015So, Iv'e been trying to make a simple Text Based RPG with Java, and it is going quite well, and my friends want to play it too but they aren't very tech savvy, so it's hard to tell them to get an IDE or use the CMD, so I wanted to know if there was a way to make my text-based game into a window, like using JFrame or something.

AutoCorrect / Replace A Word That Is Similar To A Word In File Text
Mar 13, 2015The intentions of this program is to prompt a user to enter a file name, and then reads the file. The program will prompt the user to enter a word that needs to be corrected.

Now, my second method "isSimilar" executes a similar word with more than one same letter and same length, but I dont know how to execute that whole thing in my third method "correctThisLine" . How I can call that isSimilar method and read in that text file and change that word into that?
