That's my third day working in Java using Swing and the IntelliJ Idea IDE.I'm trying to do something as simple as displaying a PNG in a window, and I'm doing this:
public class AboutRapide {
public JPanel mainPanel;
private void createUIComponents() {
mainPanel = new ImagePanel();
[cod]....
the problem is that, in the paintComponent method, the Image is never found when I run my app from the IDE, but it is when I run it from Finder in my Mac. Same application. I think it relates to how the application is launched so I guess what's a proper way to refer to a resource file with an image so it can be displayed no matter how the application is launched?Also if I generate a Jar for the application, as the resource gets into the Jar compressed file, it can't also be loaded.
I am trying to create a gambling POS system and having problems with a method trying to get a value right after it was set. A jbutton sets another jframe visible which contains buttons. Upon action of the button, a value is set and the jframe is disposed.
private void btnPrizeActionPerformed(java.awt.event.ActionEvent evt) { PrizeSelling prize = new PrizeSelling(); prize.setVisible(true);//create prize selection window bin = getButton(); //gets what button is selected to load the correct prizes for correct game prize.DBconnect(bin);//sends bin number to prize loading method
[Code] ....
As soon as btnPrize is clicked it gets the total value of the prizes selected which of course is 0 because it is ran before it is set. How can I make it wait until the window is closed before continuing?
I am trying to drag the window down wards and screen has alignment issues. I tried to use WindowListeners, Component Listeners, MouseListeners ect…
But still this problem persists as only I release the mouse after drag down it appears fine that we have handled ComponentResized() method. So how to restrict component size while keep dragging down?
We are creating a quiz as a school program, we are using netbeans and we have a little problem. The problem is that our JButton opens a new JFrame in a new window and we want it to stay in the same window. The code we are using is:
private void PlayButtonActionPerformed(java.awt.event.ActionEve nt evt) { Question1 s = new Question1 (); s.setVisible(true); }
Is it possible to make it stay in the same window?
I need that when my application is minimized notify you when something happens, like the messenger (MSN) remember? The window notifying a new message, the minimized window blink in orange, orange need not be ok? I do not even know where to start.
how to display results in a PLAIN_MESSAGE. My program is converting hex to decimal and displaying the results. Here's the code:
package pkgfinal; import javax.swing.JOptionPane; import java.util.Scanner; public class Final { public static int Convert(String userInput, int base){ int running_sum = 0;
public void run() { long currentTime,timeDiff; prevTime = System.nanoTime(); accumulator = 0; boolean TRUE = true;

When I print the fps variable to the terminal window, it show a value of ~59.9998 - very close to the frameRate of 60. That is to be expected, and works well. The problem is that when I deliberately make the game go really slow, by spamming a bunch of enemies, the game looks slow, but the FPS is still apparently ~59.9998. I thought that maybe the paint() method was not calling when it was supposed to, but that might not be the case.
This FPS counter should be working, I can't see where I have gone wrong. Is there a problem with the code, or is there another problem that might cause the screen to be redrawn 10 times a second with an FPS of 60?
I'm at the Image part of this chapter and I wrote/copied these 2 classes:
[URL]
The error:
Exception in thread "main" java.lang.NullPointerException at javax.swing.ImageIcon.<init>(Unknown Source) at image.Board.<init>(Board.java:17) at image.Image.<init>(Image.java:10) at image.Image.main(Image.java:20)
I'm fairly certain the problem is the path in this piece of code:
ImageIcon ii = new ImageIcon(this.getClass().getResource("C:GebruikersKristofferworkspaceImagessrcimageNature.jpeg"));
I've done some research and found that I should place the image in the same folder as my .java files, which I did [URL] but the problem still persists.
I have added a windowListener to my JFrame but for some reason it is not being called when I click X to close the window. I need to send a message to a server to notify it that the client window is closed. Some code snippets below (some lines excluded for brevity):
public class ChatGUI extends javax.swing.JFrame { .... setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); // I have all the window constants here but has no effect other than closing the window without calling the listener... addWindowListener(new java.awt.event.WindowAdapter() { public void windowClosed(java.awt.event.WindowEvent evt) { formWindowClosed(evt); } }); .... private void formWindowClosed(java.awt.event.WindowEvent evt) {
I'm using a jpanel with an 8 by 8 grid layout of jlabels to which I'm adding images to represent a chess board. At first, I was using the ImageIcon class to initialize my icons, but as soon as I added these icons to the labels, the labels no longer changed size with the window (which I want to happen). URL...
So I copied in the class, and initialized a different set of icons using the stretch icon class (specifically, the method that allows you to initialize a stretch icon from a filename), however, when I use these stretch icons, the result is the same. Is something wrong with the class, or with my implimentation of it, and how would I fix this?

I have been reading some java guides here [URL] .... and was trying to put a bit of what I have learnt into practice but am having some difficulty. Basically, using netbeans IDE I have created a new jFrameform so that I can place swing components in design mode. What I want to create isnt overly complicated but I just cant seem to get it. In design I have simply added a panel and a button. When I press the button I want to display an image I have located at:
/resources/images/numbers/1.png.
This is my code so far (most of it has been automatically generated from me adding things via design mode:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */
I assume I need something like below somewhere , do i need to create a draw method? if so how do I call it as it is expecting graphics2d as a parameter, what would I pass into it?
my web browser isn't displaying any web page. When I create the method editorPane.setPage(), it takes forever (about 20 seconds) to show nothing. It'll load the web browser after the 20 seconds of waiting. Here is my code:
public class Browser extends JInternalFrame {
/** * */ private static final long serialVersionUID = 4589041456161585394L; public Browser() { super("Browser", true, true); this.setLayout(new BorderLayout()); this.setVisible(true); this.setSize(Desktop.getSingletonInstance().getWidth(), Desktop.getSingletonInstance().getHeight());
I set out to make a Tic-tac-toe (Cross and Noughts) game to test my learning so far. While things have gone pretty well so far, I am absolutely stumped by my current issue. When I compile and run the code, the Grid of buttons that I generate do not appear. However, if I mouse over the window, they seem to then get refreshed/repainted. I cannot for the life of me figure out why this is happening. From Googling the issue, it seems this is either an issue with the layout manager or related to a thread conflict with the GUI? [URL] ....
I'm listing out the code for the game class and the button class.
import java.awt.event.*; import javax.swing.*; import java.awt.*; import java.util.*; public class CrossNoughtsGame { private JFrame frame; private JPanel mainPanel; private ArrayList<CNButton> buttonList = new ArrayList<CNButton>(); private boolean isX = true;
So for a test i have a small array set as a jlist which is the contents of my jscrollpane, and it appears as if nothing is there until i adjust the window size by dragging it out or in... whats going on?
I'm trying to create a chess program in java swing, and for the board I'm using an 8 by 8 array of jlabels stuck inside a jpanel with a grid layout. I would like the board to change size when the window changes size, and the grid layout accomplishes this succesfully, until I add the actual icons to the jlabels. Then the board just stays a fixed size. Someone suggested I use their "Stretch Icon" class, found here:[URL] ...., so I tried initializing the icons using one of the constructors in the class (the one that takes an image name and a boolean value for whether or not you want the resisizing to be proportionate (to maintain the aspect ratio)). However, the same thing happened. The board appears, but it does not resisize. To attempt to fix this problem, I tried simplifying my code, reducing the program to two jlabels within the jpanel, for which I then tried to set the image in the same way. Here is my simplified code:
I am making a java swing program. I have a main window that opens a JForm window when the user clicks a menu option. Then I have a button on the JForm that closes the window on click. However, I would also somehow like to make the JForm return values to the main window (according to the states of the selector components) when it is closed. How would I go about this? Currently my jForm is a seperate class called "NewGame", and inside the menu item mouse clicked method, I have the following code:
//open new game jform window NewGame newGameWindow = new NewGame(); newGameWindow.setVisible(true); newGameWindow.setLocationRelativeTo(null); //center window
Is there something I can add here to get the object's values upon the window's close? Or is there a way I can add that into the button clicked method on the actual jForm?
I have a JFrame where some elements (one, for now) have to be centered manually on the contentPane when resizing the window or changing the window state. Resizing event (componentResized) works fine but the windowStateChanged event is causing problems because it doesn't seem to "update" the contentPane's new size properly - it keeps the previous value although the window's size is obviously changed. This can be seen by simply printing the result of getSize called on contentPane.
Centering is done by programmatically changing the constraint of the component (using putConstraint, SpringLayout). The issue is that getWidth used in that method returns "wrong" values which results in an uncentered component. Maybe another listener is needed here?

I know about SSCCE guidelines but I cannot make this particular example both ready to compile and short.For unknown reasons, I am unable to post the code example. I keep getting this - "Post denied. New posts are limited by number of URLs it may contain and checked if it doesn't contain forbidden words."
addWindowStateListener(new WindowStateListener() { // no "@Override" was generated but it is the same with it public void windowStateChanged(WindowEvent e) { System.out.println("EVENT: " + contentPane.getSize() + ", " + getExtendedState() + ", " + e.getOldState()); // amusingly, states are actually correct - interchanging between 0 (Frame.NORMAL) and 6 (Frame.MAXIMIZED_BOTH) when I maximize and "unmaximize" tfArrayPanelCenter();
I am new to javafx I start using it instead of swing i used the scene builder for my forms the problem i faced i don't know how to have main screen with menu bar at top and depending the select from the menu it will open other windows and those window must be inside my window just like for example netbeans.
I don't need to open new window in separate i need all windows inside my main window and controlling over them minimize maximize perhaps.
I'm trying to right a GUI in swing, and as part of my program, I want to open a secondary window out of the main window when a mouse clicks on the main window. Then, once I click a button on the secondary window, I want that window to close and submit data to the main window (like an info form). I have almost figured out how to do this, except for one problem. By putting a variable inside my form window called "ready," and then in my main window running a loop that constantly checks if ready is true and doesn't proceed until its true, I can create the form window, modify the values in it (currently just one value called "difficulty" that's modified by a jSlider), and then when i click the "begin" button, ready is changed to true, the form window closes, and the main window can proceed. However, when I try to put the while loop checking the ready variable inside a mouseClicked method in the main window, the form window freezes when it opens, and you can't see any of its content or modify it in any way (you can't even close it).
Here is my code:
//form window class import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class formWindow extends JFrame { private JTextField instructions1;

I have put error.jsp and badpage.jsp file in public access folder that is web content in eclipsewhen I am running the code I am status code of 500 and not the errorpage.jsp message .
