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 ?
how to set background image to jpanel
View Replies View RelatedI 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:
Java Code:
private BufferedImage image;
public ParentPanel() {
try {
image = ImageIO.read(getClass().getResource("/com/dev_nna/scheduler/UI/1405188.png"));
} catch (IOException ex) {
ex.printStackTrace();
[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);
[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.
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'm just a java beginner. I've spent a lot of time installing and configuring software. I'm using Netbeans 7.3 on Windows 7, 64 bit. Recently, I downloaded opencsv from sourceforge.
With no previous experience adding libraries, I read a blog post on adding the library. I think that I then:
Start a new project.
Right click on libraries
Add jar/folder
Gave the temporary path to the .jar file
After, I read the blog post again, and realized I'd missed it. This time I did:
Right click library, Add library, Create library
However, I kept getting a message that the same library already existed. If I do the first process above, I will find the same library.
However, I see no way in Netbeans to remove it. I've deleted the test projects. And started a new one. But the library now exists for all projects it seems.
I've grepped all the files under the Netbean directory, searching for "opencsv", but found nothing. The only things in the Windows registry were locations of files.
How can I delete this library permanently from Netbeans? Short of, uninstall, then reinstall? Is there a way to list all the libraries that Netbeans has?
If I "embed" a ProgressIndicator inside a ListView it has an ugly border and a white background. It looks like there's a TextField below the ProgressIndicator.
Why does it behave like that and how to solve it so that the progress indicator is transparent.

How to find coordinates of transparent area in the image. I working on .png image which has transparent background and transparent area in the middle of the image. The transparent area in the middle look a like ellipse, so i want to find coordinate of top, bottom, left, and right of that area. I am using opencv.
I have tried to find pixels and from result that i got, i understand that pixel with rgb that equal to 255.0 255.0 255.0 is transparent. what i have in my mind is, if rgb with value that equal to 255 255 255 detected, i will put 1 into arraylist named transparent, and if it not equal to 255 255 255 i will put 0 into the list. So when i look into the list, if there is 1 0 or 0 1 it means that border between transparent area and colored area or vice versa. But, how to know if that border is between transparent area in the middle of image and the image, and not between background and the image. Am i doing this correctly?
Here snippet of code.
Mat imgMask = Highgui.imread(imgfile);
double[] pixels = new double[3];
System.out.println("channel " + imgMask);
for(int x = 0; x < imgMask.cols(); x++) {
for(int y = 0; y < imgMask.rows(); y++) {
pixels = imgMask.get(y, x);

i want to make a image transparent and to place it on top of anotherHere's the code:

I created an ImageView with an image with transparent portions. I also did some scaling and moving, which I though might cause this effect, but that is not the case. When I click on the transparent portion of the image the onMouseClick event is not fired. Other mouse events (mouse enter, mouse move, mouse exit, ...) get fired. Only when I click on the non transparent part the click event is fired.
Image img = new Image(getClass().getResourceAsStream("barrel_icon.png"));
ImageView view = new ImageView(img);
view.setScaleX(0.5);
view.setScaleY(0.5);
view.setOnMouseClicked(new EventHandler<MouseEvent>() {
[Code] ....
The area between the barrel and the shadow belongs clearly to the image, however is transparent. I am wondering if there is a reason for this behaviour and what is the best way to work around this issue, as my image has large transparent portions and the non transparent parts are hard to click on. By the way this is all based on JavaFX 2.2.
I am adding JLabels to my JPanel, and the last one always does not show up. For example if I add 3 JLabels, the 3rd will not show up. If i change it to add 4, the 4th will not show up, but the 3rd will now. Here is a snipit of what my code looks like:
setLayout(new BorderLayout());
for(int x=0; x<PEDALCOUNT; x++)
{
pedals[x].setBounds((x*PEDALWIDTH),0,PEDALWIDTH,PEDALHEIGHT );
add(pedals[x]);
}
A workaround that I DO NOT want to keep doing is to put an extra fake JLabel at the end of the for loop, that way everything I want to show up does, but the fake one does not.
I have been playing around all day trying to get this to increase the value of number by one after each new runner is added. How to get the value of number to increase after each record is added?

private String name; // runner's name
private String ageGroup; // standard, junior or senior
private int time; // runner's marathon time in minutes

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?
View Replies View RelatedI successfully added a background image on the Panel but I can't create my JButton image on top of my background image.

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:

How to remove focus from jtextfield by click the blank area in a jpanel?
When I click the blank area in a jpanel. i want the cursor in the jtextfiled lost focus
So in my binary search tree I'm trying to write a method that deletes the idem but for some reason it's not working. I have two things, I have the method and then another piece of code that tests the deletion method. Here's the actual method
public void delete(String word) {
root = deleteItem(root, word);
}
protected TreeNode deleteItem(TreeNode r, String word) {
if (r == null){
return r;
}
if(word.compareTo(r.item.getWord()) < 0){
[Code]...
Here's the test code
message = "Test: deleting 'word' -- ";
t = new BSTRefBased();
try {
t.delete("word");
result = t.getRootItem().getWord().equals(null);
} catch (Exception e) {
result = false;
}
System.out.println(message + (result ? "passed" : "FAILED"));
So for some reason it keeps saying that the test failed. Why does it keep saying that.

I want add background Image
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 -

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.
My code is below :

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.

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?
