I want to set different colors for different columns in the table. I use JLabel for setting the background color. Here is the code
private Color colorGreen= new Color( 44, 222, 74);
private Color colorYellow= new Color(255, 255, 0);
..
...
...
if(column == 0)
setBorder(new EmptyBorder(1, 1, 1, 0));
[Code] .....
But the color of the columns stays white, doesn't change.
so i'm supposed to create a jframe with only 1 button. each time you push the button it is supposed to go from red to green to blue to gray and back to red starting over. i can get is the background to change on the first click, then the button is useless for eternity. here is my code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Exercise2_59 extends JFrame implements ActionListener
{
JButton change;

How to define Cell in the table by table event?
I need to process one component drag to the table. I misunderstand, how I can see to which Cell fall the component. I tried to use Event and Mouse event handlers in my custom Cell, but they do not work. I can copy the drag event to the table and table handles it, but how to get needed Cell I cant understand.
My program's tree:
JFrame{
JPanel(That MenuBar at the top)
JPanel(That panel at center with table){
JScrollPane{
JTable
}
}
}
I want to add my custom image to that grey space right there. I guess it is a JScrollPane, because I added that orange background on JPanel that contains it. But when I add this code to my custom class of JScrollPane:
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
if(background == null){
background = new ImageIcon(ClassLoader.getSystemResource("tableBg.png")).getImage();
}
g.drawImage(background, 0, 0, null);
}
The result is the same, no changes.
Then I read some documentation. I found this method:
scrollPane.getViewport().setBackground(Color c);
It works, but it accepts only color and I want to add image. Is there any way to do that? Do I need to subclass JViewport and use paintComponent ? If yes, then how to make getViewport() method return my custom subclassed version?
This is my code and it works! But how/where do I set a background image for it to appear as the background of my calculator? The code I have for it is this -
window.setContentPane(new JLabel(new ImageIcon("C:UsersComputerDownloadschristm as1.jpg")));
My code is below.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

I want to set a background image in Java but nothing is working...
Java Code:
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JButton;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.FlowLayout;
class Background extends JPanel{
[Code] ....
Everything works fine except the picture, it's not showing. The b.png file is in the folder where the java file is. What should I do?
In NetBeans IDE >> Palette Window >> JFrame properties, I set the background color to (for example) blue but when I run with F6 key, the appearing window is always at gray color. Why?
View Replies View RelatedI would like to create a JTable.
Each cell contains an array of 4 objects:
[0] ImageIcon
[1] ImageIcon
[2] Number
[3] Boolean
1) Once JTable is displayed, each cell display only [0] .
2) Later, based on user mouse click on cell, cell should display [1]
How can I use an array with 4 values in Table Cell?
No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK);
scene.setFill(Color.BLACK);
scene.setFill() worked fine for previous versions of JavaFX.
So i was thinking about colors in java and was wondering what kinda colors are regonised by java..found this java.awt.color.. which goes very indepth with transparancy(alpha) and other formats of colors..
Question:
I wanne make a programm in java that breaks up a picture(pixels) and put it together again..Storing values of the colors and so forth..Which format of colors would be easy to start with if taking about java programming? RGB?
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.

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?
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.
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);

After generating a. JAR with Netbeans Java, when I play I see the colors of the components, the design and formatting is lost and the form gets a very basic formatting, for example, if I set a button with the color [0, 40.255] and build the. JAR after this, when I run the. JAR this button turns gray, and it happens with all the layout of the form.
settings:

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);

Do i have to make a new no argument constructor for my sliders?
I am making a quiz in Java. I need to be able to add images and colours into my quiz, to make the GUI look more appealing. At the moment, the JOptionPane that I am using looks very plain and boring. I want to be able to have my quiz running the same as it is at the moment, but I want to be able to import the images, add colours, and add Here is a copy of my quiz code:
Java Code:
package quiz;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.BufferedImage;
import java.util.Scanner;
import javax.swing.AbstractButton;
import javax.swing.ImageIcon;
import javax.swing.JOptionPane;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
[code]....
how I have added the images into the src folder:
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.
I was working on this project, and I have everything working, except that it doesn't change the colors of the shapes in the other window. Here's the code to see what I'm doing wrong:
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JDemo {
//Global Variables
static Color color0 = Color.blue; //sets the value in the color0 variable to the method Color.blue .
static Color color1 = Color.red; //Sets the value in the color1 variable to the method Color.red .
[Code] ....
The button0 is supposed to switch the color in window1, and button1 is supposed to switch the color in window0.
We have developed a theme called default.css that is extending of the default caspian.css. What we want to do is offer users the ability to override values from default.css to change colors etc. How can that be done?
