I had the opengl display attach to the JFrame before i did the runnable. But after adding the runnable the display now shows up the same size as my screen size. I have tried rearranging the
canvas.setSize();
and the
frame.setSize();
but nothing changes the opengl display is still the same size and when i try to close the JFrame first rather then close the display first i get this error:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: From thread Thread[AWT-EventQueue-0,6,main]: Thread[main,5,main] already has the context current
which points me to my
Display.destroy();
which im guessing is telling me that i am not properly disposing the display? How to attach the opengl display to the JFrame and fix the error above?
I am trying to code a program which pops up a file chooser window or dialog box to select a file first, if the user clicks 'cancel' or closes the window then the parent JFrame would not show up.
Java Code:
import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.JFileChooser; import javax.swing.UnsupportedLookAndFeelException; public final class base extends javax.swing.JFrame {
[Code] .....
The problem is that the JFrame shows up even if I click cancel in the file chooser. I am using Netbeans.
Currently, I am trying to create a program that draws a square anywhere in a 15x15 Quadrant I (Coordinate plane) grid. I am stuck on trying to get the axes displaying correctly. This is the code I have thus far:
import java.util.Scanner; public class Question2square { public static void main(String[] args) { // Axis variables int yAxismin = 0; int yAxismax = 15;
[Code] ....
Unfortunately, instead of drawing the 'L' shaped axes I desire, it displays an 'r' shape instead. I'm trying to figure out how to display the axis properly. I tried flipping the for loops but that didn't work. I don't see what else could be inhibiting this.
So I've been getting back into Java and downloaded eclipse back onto my laptop. However when I go to make a simple rectangle into a JFrame, the frame will pop up but no rectangle will be shown. Here is my main class, which sets up the JFrame...
mport javax.swing.JFrame; public class Frame{ public static void main(String[] args) { JFrame frame = new JFrame(); frame.setTitle("I hope this fucking works"); frame.setSize(400,400); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
I have been trying to make a game lately, but I can't seem to work out how to get an image to display on my JFrame. I have tried everything, copied different codes of the internet, but nothing works. Here is my code of the GUI:
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class GUI extends JFrame implements Runnable, ActionListener { JButton start = new JButton("Start nieuw spel"); JButton instellingen = new JButton("Instellingen"); public GUI() {
I have a program in which I am prompting users for integer values to display in a JFrame. I call the method below to load an array with their input:
Java Code:
public String inputAssembly(){ if (!jtfInput.getText().matches("d")){ JOptionPane.showMessageDialog(null, "Input must be of integer value."); } if (jrbFar.isSelected()){ return jtfInput.getText() + jrbFar.getText();
[Code] ....
Regardless of the input, both messages display (invalid input / got it). I've tried debugging so I know that the values are getting entered and read correct, at least to my knowledge. It is a very simple regular expression, only checking to be sure an integer was entered.
I was trying to understand Textures and OpenGL with Java. but the tutorials I find cover such a horribly broad area X_x.Basically I can get a window up, initialize openGL, and draw many repeating blocks on my screen.
I dont specifically care about minecraft. but I would like to learn how to get Many many blocks on the screenand how to apply more than one texture to a block. I cant seem to load two textures at a time without errors. I have a dumb while loop that includes a few For loops that repeat the blocks.I guess I should learn how to use Arrays to automate the block process ? Im not sure. I started reading about object buffers, but im not sure.
public static void initDisplay() { try { Display.setFullscreen(true); Display.setVSyncEnabled(true); // Drastically effects updates per second, Camera movement lowers by 98%
If it's relevant the error: java.net.SocketException: Connection reset at java.net.SocketInputStream.read(Unknown Source) at java.net.SocketInputStream.read(Unknown Source) at java.io.BufferedInputStream.fill(Unknown Source)
I am new to DreamInCode! I was creating a game using OpenGL (and slick for textures).
Using Vector3f, I make coordinates to where my camera is camera'ing (and rotation).
It was working... until I modified something. I only added shaders. When I took the shaders off I think I might of accidentally deleted something. Nonetheless the code looks perfect to me.
On the method "input()" everything runs. No errors are thrown anywhere. I have syso'd the hell outa my code. It shows no signs of breaks. I can, however, move elements I put into my program. I am 100% sure that no other class is breaking my game (soon to be).
What you should look out for: I am not really sure about the glLoadIdentity()'s and glMatrixMode(). I am, knowing a good part of, thinking it could be gluViewPort....
My problem: Can't move my camera even tho it was working before.
In a program I created, I'm using a text file that contains some texts needed for the program. The method relevant to this is something like the following.
private String wordgen(){ try { BufferedReader reader = new BufferedReader(new FileReader("src/Resources/adjectives.txt")); Random rand = new Random(); int low = rand.nextInt(400); String fil=""; int i=0; while(i!=low){
[Code]...
The program runs fine in netbeans project but once the jar is created it does not corporate with the text file. ("null" is returned) How can I attach text files to jar and exe?
I'm writing a java program with opengl and I'm trying to get it where the user would select something like lighting on in a JMenu and then it would turn the lighting on in the house/barn... I have a method called LightOn that I put gl.glEnable(gl.GL_LIGHT0); but it just doesn't seem to turn on when I call it from the action performed... Is there something I'm missing from my code that I'm supposed to use instead since I have tried it with a boolean.. So the boolean starts off as false and when the JMenuItem is clicked the actionPerformed will turn the boolean to true and call the method LightOn. In the display method I have what the light is supposed to be
So I need to create a square and make it rotate when the letter R is pressed and then make it stop when the letter R is pressed again. I need make it rotate using a maths equation that I can't figure it out myself right this moment.
Code for square:
package lab2; public class Square { public double [][] vertices = new double[4][2]; //not good to make this public public Square(double x1, double y1, double x2, double y2, double x3, double y3, double x4, double y4) { vertices[0][0]=x1; vertices[0][1]=y1; vertices[1][0]=x2;
[Code] ....
In the Square code there is a method to write an equation to rotate it but I can't figure that part out ....
The program runs well , it adds the applet but it dosn't update the interface unless I press "_"(Minimize) . To be more clear , the object paints a spring wich goes through 4 stages , it is added to the JFrame but it dosn't uptade until I minimize the frame , that is when it goes to the next stage .
The main class which calls the spring to be added to the frame :
public class principal implements ActionListener ,Runnable{ JTextField field; JFrame frame; private class Action implements ActionListener { public void actionPerformed(ActionEvent event) { frame.repaint();
When I long click item in the list nothing happens. I get no errors at all and I believe that either I put the code in the wrong place or I missed something else that stops Dialog from starting.
my validAccounts array will not fill properly and has a null value in it.I added a print statement that prints the contents of the array and it is filling correctly but the very last value is null. I am supposed to be asking the user for a account number and password and it is not printing out correctly due to the fact that the array is not filled correctly.
import java.util.*; import java.io.*; public class ATM2 { public static Scanner kbd; public static final int MAXSIZE = 50002;
