I want a java program
Program must be jframe that contain 2 buttons and a graphic.
Graphic is any thing car or human or any thing and by changing x-axis of of the graphic it will be as if it walk from place to another.
We must use the function timer that change the x-axis after defined time.
The two buttons are one for stop walking and another for resume.
This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.
This is the code copied directly from the book. What is missing:
import java.awt.event.InputEvent;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.JFrame;
public class JLeftOrRight {

This is a lab for one of my CS classes, and the assignment is to create a randomly filled array (values 10-100) and use these values as the height of an array of rectangles (essentially a bar graph)that will be drawn on a page. After that's done, the code should use the selection sort method to sort the bars least to greatest, being repainted as it's sorted.
I'm receiving no errors, the original draws just fine, and the code sorts the first position and then...it just hangs. Like it's in an infinite loop but I have all of the modifiers in place (I think. I've been staring at this code for three days straight and I don't think I really see it anymore). I've tried talking to my professor and I get that her private life is really busy right now, but she just keeps blowing me off and I don't know what to do. Anyway, done with back story and whining so here's the code.
Rectangle class:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Rectangle
[code]....
For the assignment, we are supposed to make a checkerboard with alternating colors, then put images on top of certain spaces to act like "pieces." I did the checkerboard, but whenever I go to try and put an image the checkerboard, it doesn't appear! I put the image in the same directory as my other code as well. I did some experimenting and discovered that the image is appearing, but behind the checkerboard.
Here is the code:
import java.awt.*;
import javax.swing.*;
public class CheckerBoard extends JApplet{
public void paint(Graphics g){
super.paint(g);
Image img1= getImage(getCodeBase(),"arrow1_nw.png");
g.drawImage(img1,500,500,this);
[code]....
I have created a small program with methods of the Graphics class. I want to resize the frame and make it fit the screen, but after trying various layout managers, have come to the conclusion that by setting the sizes of the various shapes specifically in the paintComponent method, I can't resize. Is it possible to resize a frame with its paintComponent methods? Maybe I'm just not using the layout managers correctly but the Graphics just wont resize. I have tried setting the weights when I used GridBagLayout.. not working. I thought maybe there is a way to set the frame or panel to take the Graphics and then resize the panel. That doesn't work either.
View Replies View RelatedI am trying to draw a binary node tree to a text file.
public class BinaryTreeExample {
public static void main(String[] args) {
new BinaryTreeExample().run();
} static class Node {
Node left;
Node right;
int value;
public Node(int value) {

This will output:

Traversing tree in order
=================================
Traversed 11

I need to print this information in the form of a graphic to a text file. so for example:

etc...
Square:
package assignment1;
import java.awt.*;
public class Square
{
private double x,y; // Current position of the square.
private Color color; // The color of the square.
private int side; // The side of the square
public Square() // constructor
[Code] .....
This is the square class, it draws an orange square that moves around in the applet viewer, works fine and as it supposed to do.
Ship:
package assignment1;
import java.awt.*;
public class Ship
{
private Square[] fleetMembers; // declare fleetMembers as an array of Square
private int total = 5; // Max number of squares in fleet
private double x,y;
Ship() // Constructor
[Code] ....
This is my FleetOfShips code. It is supposed to be a set of ships moving around together, but for unknown to me reasons it doesn't work. It does compile without any problems but when I run the applet it doesn't do anything.
So I have this line of code...
ioexception11.addChoosableFileFilter(new Jframe());
And when I compile it gives me...
error: constructor Jframe in class Jframe cannot be applied to given types;
ioexception11.addChoosableFileFilter(new Jframe());
how we call a jFrame from another jFrame .
View Replies View RelatedI have started to create a calculator using Java SWING. I am new to this and don't know a huge amount. I don't know what to do now.
How do I add actions to the buttons? So when the button is pressed it will appear in the text area?
Where do I put these commands also? Within public void gui?

I am learning out design patterns and doing a little fun project on Model Control View (MCV). I got the concept down, it is pretty simple for the most part. However my buttons are not working.
Here is the code:
public class Controller
{
private Model model;
private View view;
Controller(Model model, View view) {
this.model = model;
this.view = view;
[code]....
It runs but nothing. My other questions is how can I make a box that will print the results.
Right now, i'm trying to do is when a user clicks on my GUI button, it would display a text of information on the button they selected. I'm using an arraylist of objects and i'm trying to input the function inside the mouse click function. But I'm not sure how to properly display that information. Here is my GUI code. I'm working on the raven button. I have animal interface, with a parent class of Bird, and child class of Raven. How I could display this correctly...
public class AnimalJF extends JFrame {
private JPanel contentPane;
private JTextArea textArea = new JTextArea();
/**
* Launch the application.
*/
public static ArrayList<Bird> Birdlist = new ArrayList<Bird>();
public static void main(String[] args) {
Birdlist.add(new Eagle());
[Code] .....
So I have a Jframe that has a set of functions that act on a node. What I want to do is allow the user to expand the gui by creating new sets (copies) of these functions when they have more nodes.I thought of hiding extra sets and making it appear they are adding them by making them visible.
View Replies View RelatedI have made two classes. See below. But in my second class the buttons will not be show if I run the application.

I am attempting to get the x and y coordinate of a matrix of buttons. I have googled my way to failure and read the docs and I think I am traveling of track.
Below is where I create a matrix of buttons via Swing
public class View extends Mybuttons{
private static final long serialVersionUID = 1L;
JFrame frame;
JPanel matrixPanel, optionsPanel;
Mybuttons[][] matrixBtn;
Later in this class:
JPanel matrixPan(){
matrixBtn = new Mybuttons[25][25];
JPanel panel = new JPanel();
panel.setSize(550,550);
panel.setLayout(new GridLayout(25,25));
//creating a 25x25 matrix of buttons

In the controller class I am trying to get the index of each button in the getUnvisitedChildNode method. I need to do this so I can search the buttons around the button passed to it and check if they are been visited yet. Below getUnvisitedChildNode you will be bfs (breadth first search).
private Mybuttons getUnvisitedChildNode(Mybuttons b){
//example of some of the things I have tried
int x= Mybuttons.getComponentAt(b);
int y= Mybuttons.indexOf(b);
int j=0;
return b;
}

I'm just wondering whether it is possible to use images as a button in Java. I have two images that I want to use to create a rollover effect, is this possible? And then I would like to reset my java program when the button is clicked, is this also possible?
View Replies View RelatedI'm learning the swing options of Java, and my first exercise was the typical Chat Room. I got everything right: TextField, TextArea, the jpanel at left side and the buttons inside of it. BUT I can't order the 2 buttons (1 north, 1 south). I've already looked for answers, but didn't find anything and I tried to asked the teacher, but she was too lazy to look for the error. Here is my code:
f=new JFrame("Chat Room");
b1=new JButton("Send");
b2=new JButton("Emoticons");
public void showWindow(){
p1=new JPanel();
f.getContentPane().add(p1,BorderLayout.EAST);
p1.add(b1,BorderLayout.NORTH);
p1.add(b2,BorderLayout.SOUTH);

I am new to swing and I wanted to know how to be able to make a second row of buttons. Right now I have a text pane at the top and at the bottom one row of buttons. But I need to add another row or two of buttons. I've only been coding in Java.
public class TextPane {
public static void main(String[] args) throws IOException

I'm writing a temperature converter for class, and I'm done but one piece that I can't wrap my head around.My input scale radiobuttons work fine, but the output scale radiobuttons don't deselect automatically.

I have a GUI with a menu to do various options. However I want to change that menu to use buttons instead. I'm working with JSwing components and I'm a little familiar with the JButton function, but I don't know how to convert the menu to a button. I think I'll have to remove the menu completely..anyway I tried to start with the file menu but the compiler says no suitable method found for setForeground(javax.swing.JMenu). Why is it giving me an error related to JMenu when I'm using Jbutton objects? Can I not use JButton objects inside a menubar scope? I'll bold the area it highlighted:

How can I remove the ActionListener from the buttons of my application after i have got something happen.
Please consider the following application:

private String[] textButtons;
private Container contents;

After the line 37 executes I expect that the ActionHandler (ah) will be removed from all of the buttons but this do not happen, then all the remaining button still responding to the clicks. Where is the problem in my code.
I'm having an issue with a swing application I'm working on. Java version is 4 (I know...). I have a main screen panel with multiple sub-panels (rows). Each of these row panels contains an additional 2 sub-panels. One of these 2 sub-panels contains buttons. When 1 button is pressed, I want to disable all of the buttons on-screen (or any other way of blocking user input) until a background event finishes. The row panels do not know about each other.
The first thing I have tried doing is, when a button is pressed, getting the parent. Using the parent I then iterate through its components, and so on until I'm iterating through the buttons. For each button, I am doing a .setEnabled(false); However, this does not work, why. I've also tried wrapping this process in SwingUtilities.invokeLater() out of desperation, but that didn't work either.
What would be the cleanest way to disable all buttons? Or block all user input? I've also tried adding an opaque dialog which hasn't worked. Last resort would be maintaining some sort of button list, but I'd rather not.
