Displaying JTextField In Fullscreen Exclusive Mode Without Flickering
Mar 2, 2014
I have been stuck on this now for almost a week, the problem is that the textfield keeps flickering. I have read that swing does not work well with fullscreen exclusive mode, but I'm not sure what else to do other than create my own class similar to a textfield and detect every single key press which doesn't seem the right thing to do.
- If this line is uncommented "TextFieldTest.this.tfChatField.paint(g);" then it will display the textfield at the top of the screen, and a flickering textfield at the bottom(which is where it's meant to be)
Java Code:
package textfieldtest;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.DisplayMode;
import java.awt.Graphics;
import java.awt.Graphics2D;
[Code] ....

I'm trying to get data from a GUI input window into an ArrayList and back out via a JTable. I can get the array lists to print to the console within the input class, but I need to wire it to a data container and out through a different class. Here is code from one input class, and its corresponding output class:
Input:
public class AddClassroom extends JFrame implements java.awt.event.ActionListener {
// UI components
// are declared here...
[code]....

I am trying to create a JFrame where I have two radio buttons (choose one room or two rooms), but they need to be mutually exclusive. I know there is a lot missing from my code, but I'm trying to work through one issue at a time
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JCottageFrame extends JFrame //implements ActionListener
{
final int ONE_ROOM = 600;
final int TWO_ROOMS = 850;
final int ROWBOAT = 60;
int price;
[code]....
I believe the errors are because I am trying to add the radio buttons to the button group and making them mutually exclusive, but I'm struggling to follow the textbook on how to properly do this. When I remove the two lines of code that are causing the errors, my code compiles and the JFrame shows correctly. The only issue is that it is allowing me to select "One room" and "Two rooms" at the same time.

Have this game which is 1280 by 720 and i want it to be fullscreen.....but i dont just want the size of the frame to change i also want everything inside it to "stretch"..... So for example if i had a 100 by 100 frame with a 10 by 10 image in it, and i tried to stretch the frame to the users screen which is 200 by 200, the image inside the frame would also stretch to 20 by 20... How do i do that?.........

I got this code with mode methods. The results is not exactly what I want.
Code:
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.Random;
import java.util.*;
public class ProcessMarks {
private static final int NMARKS = 125;
[Code] ...
Result (it's repeat number):
*Mode is = 53
*Mode is = 53
*Mode is = 53
*Mode is = 53
*Mode is = 53
*Mode is = 62
*Mode is = 62
*Mode is = 62
*Mode is = 62
*Mode is = 62
*Mode is = 67
*Mode is = 67
*Mode is = 67
*Mode is = 67
*Mode is = 67
*Mode is = 77
*Mode is = 77
*Mode is = 77
*Mode is = 77
*Mode is = 77
*Mode is = 78
*Mode is = 78
*Mode is = 78
*Mode is = 78
*Mode is = 78
*Mode is = 85
*Mode is = 85
*Mode is = 85
*Mode is = 85
*Mode is = 85
Result that i want it to be (number appear only once):
*Mode = 53, 62, 67, 77, 78, 85
or
*Mode is = 53
*Mode is = 62
*Mode is = 67
*Mode is = 77
*Mode is = 78
*Mode is = 85

Basically the code is for a game which is displayed in a window. The statement if(false) //full screen mode is confusing me a little. How does this if work? it doesn't seem to be testing for anything so how does it ever get set to full screen mode? Is the if even needed? why not just code windowed mode?
public class Window extends JFrame{
private Window()
{
// Sets the title for this frame.
this.setTitle("My test");
// Sets size of the frame.
if(false) // Full screen mode

The following code uses a column constraint to specify that a column of labels should extend horizontally in their cell but they don't as you can see by looking at their border. My mistake or a bug?

I need to create a program that draws a graph, but for now, all I have done is two lines: the X and Y axis. The program is designed in a way as to automatically resize the graph when the window is resized.
Is this code in some way extremely inefficient? I get TERRIBLE flickering when I resize the window. Is there something that will at least reduce the flickering?
mainApp.java:
import java.awt.*;
import javax.swing.*;
public class mainApp {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setSize(300,300);
frame.setVisible(true);
[Code] ....
I have added a screenshot that shows the window flickering.

I am trying to call another swing frame from my current frame. And after calling second frame i dispose the current frame.
But while second frame coming on the screen, current frame gets dispose and second frame takes some seconds to appear on screen.
So its creating a bad flickering effect on screen and its not suitable for my application.
I want that first frame will call sencond frame and it will not look like second frame is called. I just want to cancel flickering effect.
Here is my source code.
1st Frame:
public class Welcome extends JFrame {
JFrame f;
JTextArea nameField,nameField1;
JLabel lable;

why is it that if i wrote the code like this.
public void DrawSnake(Graphics g) throws IOException {
Image image = ImageIO.read(this.getClass().getResource("body1.jpg"));
Image image1 = ImageIO.read(this.getClass().getResource("body.jpg"));
Image headr = ImageIO.read(this.getClass().getResource("headr.jpg"));
Image headl = ImageIO.read(this.getClass().getResource("headl.jpg"));

I'm trying to set up a splash screen where a native splash screen is shown initially and then replaced with the stage from my preloader. This is fairly simple to do. I use the below code to get everything lined up properly.
private void alignStage(Stage stage) {
SplashScreen splashScreen = SplashScreen.getSplashScreen();
if (splashScreen != null) {
// Align the stage based on the current splash location
Rectangle bounds = splashScreen.getBounds();
stage.setX(bounds.getX());
stage.setY(bounds.getY());
[Code] ....
The problem I'm having is that my Stage isn't actually shown by the time the commented event gets fired. The API for onShown says:
Called just after the Window is shown.
My guess is the window has transitioned to being shown, but there's a slight delay until it gets rendered on screen. If that's a decent assumption, is there a reliable way I can make sure my preloader stage is visible on screen before I hide the native splash?
The best option I can think of so far is to delay hiding the native splash until the preloader gets the BEFORE_START notification. This works (no flicker), but, since both splash screens are actually visible for a while, using a transparent splash doesn't work very well (which actually isn't too big of a deal).

I have a supermarket checkout line where i have a list of available products on the left and then a basket on the right with the products in. The products are listed in an array, here is the product class
public class Product {
private String name;
private double weight;
private double price;
[Code] ....
with getters and setters excluded, and the list these are put into
public class productList extends DefaultListModel {
public productList (){
super();
}
public void addProduct (String name, double weight, double price, int code){
super.addElement(new Product(name, weight, price, code));
i have the price for each product to be displayed in a text field with the following code
addBasketItem = new JButton();
getContentPane().add(addBasketItem);
addBasketItem.setText("Add >");
[Code] ....
defaultCheckoutList contains my available items and defaultMainList is the basket, with mainTillPrice being the jtextfield.
This works to get the price however it just replaces each time i make a new entry with the price for the next item, i want a total of the price of all the items i have added, but not sure how.

Will I'm tying in my code to set a default number for the JTextField that when the user decide not to put any numbers. Like let say that I want the textfield set to 0 , so then the user do not file it it won't make any problem to the program because its already has a default number.
if (stringGQ != null && stringGW != null && stringGP != null){
stringGQ = gMQ.getText();
stringGW = gMW.getText();
stringGP = gMP.getText();
weightPrice_1M = Double.parseDouble(stringGW) * Double.parseDouble(stringGP);
[Code] .....
Note: This is a small part of my code. when I leave it empty it take the 0 as a value, However, when I write in text field it also take the value of a 0 and the finalTotal is also = to 0.what I'm doing wrong.

I am creating a slot machine using eclipse. I am trying to get the "winnings" JTextField to be updated in a way so that when the random images have been selected it adds to the number that is already displayed in the JTextField as opposed to what it is doing at the minute which is just displaying how much was won on that particular spin. I am also struggling to set a code for when noting is won, nothing is added. My code is below.
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

designing a program which allows you to buy stuff from the jframe with 10x items each with different pricing, so once you click the image button the cost of that is displayed in the textfield, ive been trying to set the jtextfield to a decimal point but have not been able to so far,
if (source == jBSofa) {
System.out.println("Sofa");
{
dTotal = dTotal + 599.99;
jTotal.setText(Double.toString(dTotal));
DecimalFormat myFormatter = new DecimalFormat("#####.#");
String output = myFormatter.format(dTotal);
a visual aspect of it.

How would I display certain output text if the text entered equaled "text".
So lets say you enter a question into a JTextField. You press a button that submits the text. The output displayed depends on what the question you asked was.
Think about it as "If question = What color is the sky? On submit, display text "Blue". How to implement this.

I have been reading several suggested solutions for implementing autocomplete for a JTextField. However, the documentation is a bit confusing to me. It seems like they mostly require switching to a JComboBox. Can I or can I not continue to use a JTextField and implement an autocomplete feature? I also saw what I thought was a built-in autocomplete "decorator" for swing objects (although it was not clear if it can be used for JTextField) but most of the implementations seem to start from scratch. Any simplest way to implement this (assuming those 2 conditions are not mutually exclusive)?

I am trying to get the data entered in a JTextField into a JTable but not clear on how. The LeftPanel is where the button is located and the RightPanel is where the JTable is. I want the actionPerformed to update the row of the JTable but I can't figure out how. There is another class that controls the GUI but did not think it was necessary to include. Also, I am aware that I am getting an error at the addRow line, can't seem to alleviate it.
public class LeftPanel extends JPanel {
