Order Buttons In A JPanel

Sep 22, 2014

I'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);
}

Extract Higher-order Bits Of Random Number In Order To Get Longer Period

Mar 1, 2014

One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.

I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?

NullPointerException Adding JPanel To JPanel

Jun 17, 2014

I have a Main() class that extends JPanel and I'm trying to add Card() that also extends JPanel.When I add a Card() or Main() object to the JFrame directly, it works fine. The problem arises when I try to add a Card() object to the Main() object.

I edited the code a little bit to make it easier to read so hopefully it's fine.

Main() code:
public class Main extends JPanel implements Runnable {
// HARDCODED OPTIONS
public static final int WIN_WIDTH = 1200;
public static final int WIN_HEIGHT = 800;

public static final int GRID_X = 9;
public static final int GRID_Y = 5;

Where do I put these commands also? Within public void gui?

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
lic class Calc extends JFrame implements ActionListener {
  private JButton ZeroButton = new JButton("0");
private JButton OneButton = new JButton("1");

MCV - Buttons Not Working?

Sep 7, 2014

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.

Using GUI With Buttons And ArrayList

Sep 18, 2014

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());

Swing/AWT/SWT :: New Set Of Buttons

May 22, 2014

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.

Getting The Index Of A Matrix Of Buttons

Dec 7, 2014

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

[Code]...

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;
}

[Code]...

How To Change Menu GUI With Buttons

Apr 23, 2014

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:

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

Creating Buttons With Values?

Dec 6, 2014

I did or at least thought I create a matrix of Buttons with values inside of them.

I will show code snippets from different classes:

Made into the view class
for(int i=0; i<25; i++){
for(int j=0;j<25;j++)

My IDE says counter cannot be resolved or is not a field. I understand what it is saying but why not? I try my best not to put a bunch of code on here.

Disabling All Screen Buttons

Apr 29, 2014

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.
