Button Colors Differ In XP Verses Windows 8

Apr 21, 2014

I created a GUI with NetBeans. When I run the program in XP and the program changes the button colors, the whole button changes color. In this case, from "background" to "Green".When I run the program under Windows 8 only the border of the button becomes green.

NetBeans seems to use the Look and Feel "nimbus". I single stepped through the program on both computers and it looks like a request for nimbus does not cause an exception on either computer.

Swing/AWT/SWT :: Button Colors Different In XP And Win 8

Jan 26, 2015

I have a program I wrote long ago. I change colors of buttons at times. Here is the code:

for(int Player=0; Player < 8; Player++){
//make them all background
dealerLabels[Player].setBackground(new java.awt.Color(212,208,200));
}
//Now make the new dealer green
dealerLabels[dl].setBackground(new java.awt.Color(51, 255, 0));

The color of the buttons has always changed under XP but when I run the program on Windows 8 only the edges of the buttons change.

Java-8 :: Button Width Calculated Wrong Under Windows?

May 7, 2014

I am developing a JavaFX application under Java 8 on my Ubuntu 14.04 (32 bit) system. When I run it on the Ubuntu box, all is fine, but when I run it under Windows 7 Home Premium (64 bit) with the same Java8 release installed, all my buttons have their text ellipsised (sp?). Why the behavior is different? Or is this a bug in JavaFX? Here are the particulars:
 
fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?><?import java.util.*?><?import javafx.geometry.*?><?import javafx.scene.*?><?import javafx.scene.control.*?><?import javafx.scene.layout.*?><?import javafx.scene.text.*?>
<AnchorPane id="AnchorPane" prefHeight="91.0" prefWidth="-1.0" xmlns:fx="http://javafx.com/fxml"> 

[Code] ....

Java:
java version "1.8.0_05"Java(TM) SE Runtime Environment (build 1.8.0_05-b13)

Return True If Array Contains 3 Adjacent Scores That Differ From Each Other

Mar 12, 2014

Assignment: Given an array of scores sorted in increasing order, return true if the array contains 3 adjacent scores that differ from each other by at most 2, such as with {3, 4, 5} or {3, 5, 5}.

scoresClump({3, 4, 5}) → true
scoresClump({3, 4, 6}) → false
scoresClump({1, 3, 5, 5}) → true

Codingbat AP-1 3rd question

public boolean scoresClump(int[] scores) { 
for (int i = 0; i < scores.length; i++) {
int a = scores[i];
int b = scores[i + 1];
int c = scores[i + 2];
if (Math.abs(b-a) + Math.abs (c-b) <=2)
return true;
}
return false;
}

I got it right for some of the input, but not one of them. I tried to use the for loop and if statement on a specific input that I got wrong:

{4, 5, 8}
scores[1] - scores[0] = 1
scores[2] - scores[1] = 3

I suspect it has something to do with the for loop, but I don't see the problem with it. It should work, shouldn't it?
But anyway, here is the error for {4,5,8} :

Exception:java.lang.ArrayIndexOutOfBoundsException : 3 (line number:7)

Board Of Colors And Players

Sep 14, 2014

My assignment is for a game where there is a board of colors and each player draws a color and moves to that position on the board. It will then output how many cards total in the game it took whichever player to win. If no winner it outputs the number of cards that none won by going through. I attached the file that corresponds with my code.

This is the desired output:

Player 1 won after 7 cards.
Player 2 won after 8 cards.
No player won after 8 cards.
Player 2 won after 4 cards.
No player won after 6 cards.
Player 2 won after 8 cards.
Player 1 won after 4 cards.
Player 2 won after 8 cards.
Player 1 won after 1 cards.
No player won after 200 cards.
Player 4 won after 100 cards.

import java.io.*;
import java.util.Scanner;
public class ProgrammingAssignment1 {
/**
* @param args the command line arguments
*/
public static int players;
public static int cards;
public static int boardlength;
public static String board;

[Code] .....

The output that I get is:

Player 1 won after 3 cards.
Player 2 won after 8 cards.
No player won after 8 cards.
Player 1 won after 3 cards.
No player won after 6 cards.
Player 2 won after 8 cards.
Player 1 won after 3 cards.
Player 2 won after 8 cards.
Player 1 won after 1 cards.
No player won after 200 cards.
Player 4 won after 100 cards.I guess I'm supposed to set the playerPos[] to -1, but I'm unsure how.

IndexColorModel 255 Colors To BufferedImage

Apr 4, 2014

I need to write an image to a .png with a 255-color indexed color model. I know usually do it like this: Java Code: BufferedImage img=new BufferedImage(width,height,BufferedImage.TYPE_BYTE_INDEXED,model); mh_sh_highlight_all('java'); but that doesn't work with models with 255 colors (as opposed to 256 colors). I'm fairly sure it is the BufferedImage creation that is the problem, as when I call model.getMapSize(), it returns the correct size.

The extra color added to the image's index is 15,15,15.

Should I be something other than a BufferedImage to write the image, or should I be using a different constructor for BufferedImage, or am I doing something else wrong?

Multiple Colors For A Text Field

May 25, 2014

I have a question about JTextArea colors. When i set the color to blue and then write something on the JTextArea (JTextArea.append) and then set it back to black everything will be black. How can i solve that? Like in Notepad++ or Eclipse when you write keywords in a JTextArea (where you write your code) only some words change color.

This is my code:

// All the imports
public class whatever extends JFrame {
JTextArea a = new JTextArea();
public whatever() {
super("Title");
add(a);

Swing/AWT/SWT :: JTable Not Able To Render Rows In Different Colors

Aug 24, 2014

I have a jtable , a customtablemodel and a customcellrenderer with the NetBeans IDE. I want to have different colors for different rows. But anytime I run the application , the rows are not painted as expected. The code snippets are provided below.

This code is from the jtable :

duesTable = new javax.swing.JTable();
duesTable.setModel(duestableModel);
TableColumn tcol = duesTable.getColumnModel().getColumn(2);
tcol.setCellRenderer(new CustomTableCellRenderer2());
duesTable.setAutoResizeMode(javax.swing.JTable.AUTO_RESIZE_OFF);

this code is from the TableCellRenderer

public class CustomTableCellRenderer2 extends DefaultTableCellRenderer{
@Override
public Component getTableCellRendererComponent (JTable table,
Object obj, boolean isSelected, boolean hasFocus, int row, int column) {
Component cell = super.getTableCellRendererComponent(
table, obj, isSelected, hasFocus, row, column);

[Code]...

This is from the Table Model.

public class DuesTableModel extends AbstractTableModel implements TableModelListener {
private List<List<Object>> dataList = new ArrayList<>();
private String[] header = { "ID"," PAYMENT YEAR" , "AMOUNT"}; // Payment year is a date
datatype
private int minRowCount = 5;

Write TreeMap That Can Hold Maximum Of 20 Colors And Minimum Of 8?

Dec 11, 2014

I am trying to write a TreeMap that can hold a max of 20 colors and a minimum of 8. I have a while loop using pollLastEntry to limit the max but I can't figure out how to set the minimum. The hex number is the map's key and the color name is the value. I tried to use entrySet() and iterator to just double the size of the map but map can't have multiple keys with the same value. It also seems that to set a minimum would require some kind of further input(which I'm trying to avoid) of colors and their hex numbers.

//Method to hard code the colors into the map
public TreeMap<String, String> cm() {
//Color Map <Hex number, Color name>
//Uses a TreeMap to keep all the colors organized by key
TreeMap<String, String> cMap = new TreeMap<String, String>();
cMap.put("FFFF00", " Yellow");

When Click On New Button / All Icons Except Button Just Clicked Don't Display

Oct 16, 2014

The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.

import java.awt.BorderLayout;
import java.awt.EventQueue;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.SwingConstants;

Swing Button That Creates A New Button

Nov 29, 2014

I am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?

public class MadLibs {
public static void main(String[] args) throws IOException {
////////////////////
//TEXT PANE WINDOW//
////////////////////
//Set up a JTextPane object : The JTextPane is a specialized form of the JEditorPane
//designed especially for the editing (and display) of styled text.
final JTextPane pane = new JTextPane();
