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 -
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
/**
* Program using SWING components to create a Christmas themed Calculator.
*/
public class ChristmasCalculator implements ActionListener
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?
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?
Is there any class which lets me set brightness to an image, preferably BufferedImage but it doesn't really matter, and then whenever desired remove the brightness. I have tried using RescaleOp, but it doesn't satisfy the latter criterion. When I have brightened the image, I can't seem to get it back to normal.
Java Code:
RescaleOp op; if(image should be brightened){ float scales[] = {2f, 2f, 2f, 1f}, offsets[] = new float[4];
op = new RescaleOp(scales, offsets, null); op.filter(getImage(), getImage()); }else{ float scales[] = {1f, 1f, 1f, 1f}, offsets[] = new float[4];
op = new RescaleOp(scales, offsets, null); op.filter(getImage(), getImage()); } mh_sh_highlight_all('java');
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.
I have tried to set a background Image to a calculator usinf JLabel. However I've ended up with my image to the left of my calculator , my calculator textfield becoming the size of the background image and then all my buttons below it. Like so(if you can view the image)..Calculator.jpg
How can I fix this so the background is behind my buttons and my text area is a normal size again.
Actually i want to develop a game for that i need a background with a image and over this background i want to move some objects (which are images) and also want to add some button.
Here is my Code.
The Main Class
package last; import java.awt.*; import javax.swing.*; public class Last extends JFrame{ public static void main(String[] args) { Last l =new Last(); l.setSize(900, 600);
[Code] .....
When i execute the above program only the background image is shown.
I would like to learn how to add an image background to a window in java that I can put controls like buttons, textboxes, and checkboxes in front of. I already tried using a JLabel with an ImageIcon but I cannot overlay controls over the JLabel. From what I understand there are multiple ways to do this. What is the best way and how can I do it?
I am trying to set a picture in the background of my GUI. I had already made the GUI with the all the required buttons and labels. So I was trying to separately make a class which extends JPanel and add a picture to a panel by overriding the paintComponent() method, and then added it to a frame (I did not set the default layout of the frame, so it was the default...), and it worked very fine. Here is the code:
Then I needed to add this panel with background picture to the background frame of my already made frame with all the buttons on it.The layout of the parent frame of my GUI was BorderLayout(50, 50), panels (with buttons) were added to it n the north and south positions.
Then I tried to add a JPanel with the background image to the parent frame (of my GUI), (I wanted it to elapse the entire frame, and come under all the buttons and controls, which were only present in the north and south positions of the border layout), and then the panels holding the buttons to the north and south postions of this panel, everything disappeared.
If I don't do anything except adding this panel with the background image to the parent frame, it only takes up the place not taken up by the two panels on the frame (Border Layout)
how to add this panel to the parent frame of my GUI such that it elapses the entire parent frame's background, and the panels containing the buttons should sit on it.
IMPORTANT PARTS OF CODE:- Java Code: //TOP LEFT PANEL JPanel topleftpanel = new JPanel(new FlowLayout(FlowLayout.LEFT, 5, 5)); parentPanel_top.add(topleftpanel); topleftpanel.setOpaque(false);
I've tried multiple things but I can't seem to figure out how to get my JButton over the background graphics. On lines 104-108 I create the JButton I need to put on the screen, though I have no clue how to draw it. How I can paint over this background and have my button stay there?
public static final int WIDTH = 1024; public static final int HEIGHT = 640; private Thread thread; private boolean running; private BufferedImage image; private Graphics2D g;
I've tried to add a background image to my calculator , however I have ended up with this ...Calculator.jpg
How do I fix it so the image is behind my buttons etc (as a background) And how do I fix my textarea so it is back to the normal size and not the height of the image? My code is below, please be specific.

I recently made a game. But, I want to package it and give it to my friends. I know that I can create a jar of it and add the images to the folder, but what I would absolutely love is for it to just be a picture with the game name and click to run. The second thing is to replace that java icon to an icon of my preference, which I have been told numerous times to do with
I'm making a pong game but I would like to use a basketball court image behind my code to give it a prettier look (the ball is also a basketball), but I can't seem to get my code to appear on top of my basketball court image, the image just overlaps my code.
In my program one of the panel has a background image and I need that background image to be updated/refresh or changed whenever the panel reaches certain number of clicks
here's the code
Constructor/gui import java.awt.*; import javax.swing.*; import javax.swing.text.*;; public class demo { JFrame frame = new JFrame ("Idle Game Test!"); JPanel backGroundPanel = new JPanel ();
[code].....
also is there other way to access those static variables? the way i implemented them works but i do think there are other ways that are more suitable or better but i cant figure out.
How can i add a background image for this code without disappearing the button and label? I want a frame that has a background and still shows the buttons and label that I place. and how can I insert Buffered Reader in this code, this is a file organizer, but it only shows first line of a text file. I want to show the whole text file. And is it possible to also show path of the file?
I am unable to clear disappear the background of .png image added in a translucent JPanel. I have tried it using JLabel but the image added is with white background. How can i get rid of this white background...
import javax.swing.*; import java.util.*; import java.awt.*; public class HomePage { JFrame frame; JPanel pnl1, pnl2, pnl3; JLabel lbl;
Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.
I stored an image into MySQL database using swings and hibernate but I am struggling to retrieve that image from MySQL database and display same image in the jTable cell and same as on jLabel whatever I retrieve from the database using swings and hibernate .
