I've just started working on a program and I'm already having difficulties with the program. I can't get the background color to change from the basic gray color.
Java Code:
import javax.swing.JFrame;
import javax.swing.WindowConstants;
import java.awt.*;
import java.lang.Object;
import java.awt.Color;
public class FrameDemo{

how can we set the background colour of jframe in java
View Replies View RelatedI have added a background image to this JFrame (see image attached) as I want the buttons and field to just be on top of the image, how to remove the colored part of the JFrame that is left?
View Replies View RelatedNo 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.

also if theres any way to shorten up what I have there, that would be great.

I have a Jpanel with JButtons on the panel is it possible to change the background color of the pannel but leave the JButtons thr default color
View Replies View RelatedI'm using eclipse to run my java program.
I want to be able to change the background color of the console when the user types in a particular command..
e.g User types: color blue
Then the background color of the console should turn blue
Is this possible and how would I go about doing it?
I am trying to go about making this applet a bit different then normal. The issue I am having is it is drawing an applet but, not the right dimensions, it's able to be resized, lastly the background color is not being set. I mean, I suppose I could call paint() and just draw it out but, I read that I could make the applet pop out to the dimensions I would like. None of this is working sadly.
package com.powder.game;
import javax.swing.*;
import java.applet.*;
import java.awt.*;
import java.util.*;
import java.io.IOException;
import java.lang.Math;

my exact question is can I rewrite the applet to make a pop out window and should I just call paint()?
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'm displaying a table with several read-only pieces of data, and a checkbox field that toggles the row color. The background color for the checkbox is not toggling correctly. I put together a SSCCE:
import java.awt.Color;
import java.awt.Component;
import java.util.ArrayList;
import java.util.List;
[code]....
If I comment out the Nimbus look and feel, it works as expected. I googled this problem and found one possible solution on Stack Overflow. Their suggestion is:It's a bug in the synth-installed renderer, quick hack is to force the rendering checkbox opacity to true: ((JComponent) table. get Default Renderer(Boolean.class)).setOpaque(true);
I tried using this line and setting the opacity to true, but it renders the background white. I'm using Java 1.7.0_25.
No matter what I did, and searching for every piece of setBackground, The background color of the JTabbedPane is light blue.

I am trying to put a button (in a container) on a jpanel in a jframe with a background but the container is covering up the background with white color.Below I have an excellent SCCE:

Basically I just need to set the containers background to transparent.
On a web application i can take a pdf cut it and convert it to html. As a result of this is that i can have my own design(Background) on HTML and then use it on jsp.
Is there a way to do this also in swing ? take a pdf and convert it to jframe or something similar so that i can have my own frame design (Background)?
i've worked with java for 1 month, i'm designing some practices at Netbeans IDE. my problem is i tried to make a single colorful interface using panels, adding colors and i want to know if i exist a way to give a color to the JFrame (i tried to use the background color option but this didn't work).

I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).
In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...
However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.
Here is what I have tried:
private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross
if(cube.bottom.square[1].charAt(0) == topColor){
while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){
rotateBottomClockwise(1);
System.out.println("Trying to align side color...");
[Code] .....
The print out of the ELSE IF is:
alignment is: W-G and tops: R-R
NOW ITS ALIGNED
even though the sides, index 4 and 7, are NOT aligned with each other
I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.
Here is how it prints out
** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube
** ** ** R6 W5 O4 ** ** **
** ** ** R3 W2 O1 ** ** **
B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube
B2 G5 R8 W4 R5 Y6 O2 B5 G8
O7 W8 R9 B7 B8 B9 R1 R4 R7
** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube
** ** ** Y2 Y5 Y8 ** ** **
** ** ** B1 G6 W7 ** ** **
** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube
** ** ** R2 O5 G2 ** ** **
** ** ** W1 W6 G3 ** ** **
Here is the cube showing the top, left and front side
Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.
I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2
I'm trying to draw an image in grayscale. This is my code:
Java Code:
public void paintComponent(Graphics g) {
super.paintComponent(g);
setOpaque(true);
BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_BYTE_GRAY);
Graphics g1 = image.getGraphics();
g1.drawImage(CardData.CARD_ART[cardID], 0, 0, null);
g1.dispose();
setOpaque(false);
} mh_sh_highlight_all('java');
For some reason, nothing displays.
I have to write a program for class that basically uses Paint Component to draw a bunch of rectangles to look like a building then have them change color randomly. I am stuck I can't figure out how to make it draw the rectangles in rows and columns to look like the building i can make it display multiple squares randomly however but thats not the assignment.. here is my code
package labBuilding;
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JPanel;
@SuppressWarnings("serial")
public class Building extends JPanel {
[code]....
import java.awt.*;
public class Program5 {
public static void main(String[] args) {
DrawingPanel panel = new DrawingPanel(300,500);
panel.setBackground(Color.white);
Graphics g = panel.getGraphics();
g.setFont(new Font("Helvetica", Font.PLAIN, 12));
double ball = 10;
[code]....
I'm fairly new to Java and am having a hard time with this particular assignment. The program runs and shows up on the drawing panel fine but I can't get the lines quite right.Capture.jpg
I've got a question about drawing animations in Java (SWT). I try to draw an animation of some process.
When i use canvas.redraw() it seems like program firstly erases everything that has been drawn and then draws again.
My program draws about 1000 of rectangles per time step so animation doesn't looks smooth - it blinks all the time and I can't avoid drawing that many rectangles.
Is there a way to make it look smoother (for example to paint new objects over old ones, without erasing them)?
I won't paste code, it's rather large.
I have a problem which can't solve it for 2 days search. I need to draw 3d shapes , i downloaded all packages and set an example code and run it ...
