Swing/AWT/SWT :: Loading SVG Images On JPanel With Transparent Background
Mar 27, 2014
I'm working on loading SVG images on Jpanel using "Apache(tm) Batik SVG Toolkit" , but after the image get loaded it has "white background" and "not transparent" one like PNG images.
I checked "fill" of rect attribute on the xml file of the svg image and it was correctly set to none, I also Tested the image on html document and it was trasparent, but in my java app it has white background.
The Question is there any way to load SVG images with transparent background on Jpanel ?
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;
I have a class Tile that extends JPanel within the constructor for Tile I have set the opacity to false so that I can place tiles atop each other and see parts of the tiles below and the background through those parts of the tile that are not being drawn on. This implies that I am using paintComponent within Tile to display the image of the tile I want shown on this object.
The tiles are stacking perfectly. But I find that if I click on a tile through the transparent area of another tile, it is the top tile (transparent area) that retrieves the mouse click. This makes perfect sense, but is there a way to allow the mouse click to pass through transparent portions of the JPanel?
I've considered writing my own method to determine if the mouse click was within bounds then if it was outside the bounds of the object, find a way to pass the click event to the tile below. But this would be extremely challenging if the tiles were implemented as donuts (with holes in the center) or as some other obscure shape with transparent sections.
I am making a game in java and i want to make a title screen. What I am trying to do is make a jpanel and load another jpanel when a button is pressed in one of the japenls. Here is the code for the runner
import java.awt.BorderLayout; import javax.swing.JFrame; public class Runner extends JFrame { // Have these set up so they can be seen everywhere public static final int GAMEWIDTH = 540; public static final int GAMEHEIGHT = 710; static boolean loading = false;
[Code] ....
here is the code for the jpanel that loads the other jpanel
I usually code in PHP, C++ and ActionScript.I'm trying to follow an example of how to add images to a full screen application. What he does is that he adds a JPG background image, and then 4 PNG images. I tried to do it like I always do, by writing the code by myself looking at the book. It didn't work. I searched for errors in the code, changed some things, tried different things, but it didn't work. Then I tried to use his own code, that I downloaded from his website. That didn't work either.. I tried to find another way to add an image, and I can't seem to figure out a way to implement images in any other way into this class that's written in this book.. My Java programming level isn't just high enough.
Here's the code for the file where the images load, downloaded from the authors website (I've modified the brackets and some spaces so that it becomes easier to read):
Java Code:
import java.awt.*; import javax.swing.ImageIcon; import javax.swing.JFrame; public class ImageTest extends JFrame { public static void main(String[] args) { DisplayMode displayMode;
I've searched everywhere but found no way to disable loading of images by Java WebEngineHow to do it?
Research done:
I found some ideas, such as using URL.setURLStreamHandlerFactory() to use my own URLStreamHandler, and having that analyze the URL to only return URLConnections for URL's that don't end in .jpg .png etc.
But that has many problems: Sometimes the image url doesn't end in .jpg, if it's a dynamic image, such as a captcha. So how can I disable automatic image loading from WebEngine?
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class sample{ public static void main(String args[]){ JFrame frame = new JFrame(); frame.setSize(300,300);

To limit the amount of drawing done i want unmoving objects to be painted once. So i set a boolean. When it first load the boolean is false so it draws then after first draw i never want it to draw the objects agian but leave them on the screen. Now in this if you run it you get a black screen.
If you didnt have the "getContentPane().setBackground(Color.black)" it would work fine and show a blue brick. Is there something I don't understand about the setBackgound Function that makes it automatically redone even when not called? and if so how do i overwrite this?
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:
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 am trying to use images as my backgrounds for my JPanel.the problem is when I run the program the images don't show at first.T hey start to show after I have switched to another panel and then switch back. Here are my codes
I read many posts online and watched tutorials on YouTube. I can't seem to get this work. Notice I am not using any drawing/graphics capabilities - I'd like to keep it this way as we have not gotten that far yet in my studies.The image is in a source folder titled Images under/in my project.
Java Code:
private JPanel jpImage = new JPanel(); private JLabel lblImage; private ImageIcon image; private Image img; // All those above defined prior to method // Within method (relevant to code above) ...
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.
I want to be able to get an image online and display on my JPanel but for some reason my image wont load and just shows a blank square, but when I try to load an image from my hard drive it works just fine.
I have added the image in the src and bin directories and cross-checked that the name of the image file is correct..Here is the main class
import javax.swing.*; public class apples { public static void main(String args[]) { JFrame frame = new JFrame(); MyDrawPanel wid = new MyDrawPanel(); frame.add(wid); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); frame.setSize(300,300); } }
and here is the class that does the image adding part
import java.awt.*; import javax.swing.*;
public class MyDrawPanel extends JPanel { public void paintComponent(Graphics g) {
Image image = new ImageIcon("b.png").getImage(); g.drawImage(image,20, 20, this); } }
I am trying to make a program where a user can enter guests name for a hotel, the JTable includes rows for the name of the tenant, the room number, month etc.
I've made the table, however I am having some trouble in saving the data that I put into the table. I used jtextfield and a jbutton to but data into the jtable. I am trying to save the data, and load it just buy clicking a button.
table.setModel(new DefaultTableModel( new Object[][] { }, new String[] { "Room", "Name", "Month", "Payment"//table rows } ));
This is my basic table. And what I'm trying to do to save the data is:
DefaultTableModel model = new DefaultTableModel(); private JFileChooser myJFileChooser = new JFileChooser(new File(".")); private void saveTable() { if (myJFileChooser.showSaveDialog(null) == JFileChooser.APPROVE_OPTION ) { saveTable(myJFileChooser.getSelectedFile());
[Code] ....
When I run my program, I'm able to click on a button, and the dialog box will appear, I'm also able to save the data to a file. However when I click on the retieve data button I made the dialog box opens, the file is there, however when I click it, nothing happens.
All I want to do is load an image into a swing JLabel and display it, but I'm going to have to make a JAR of the program and submit it for grading, so I need to be able to get the path of the image file relative to the JAR (at least I think that's how it works - I've never made a JAR before. Right now I'm just trying to load it from a path relative to my netbeans project). I've tried at least 20 different combinations of paths, file locations within the project, etc., but nothing works.
Anyways, here's the test class I've been using to try to figure this out in its current iteration. Right now the image I want to load is in src/resources and the class is in
src/imagedisplaytest package imagedisplaytest; import javax.swing.*; import java.awt.*; public class ImageDisplayTest extends JFrame { private JLabel testLabel; public ImageDisplayTest()
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)?
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;
I 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?
I'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:
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.
