Title says it all i want to get these two components:
Java Code:
package TestVersion;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import javax.swing.JPanel;
public class GameWorld extends JPanel {
private int charX = 225;
private int charY = 225;

i want to know how i can add more than one frame in a single frame means main window or frame will be constant and only components will be chang or vary as in a software or game .
View Replies View RelatedMy components dont show until I resize the frame.
public class Frame extends JFrame{
private final static int WIDTH=400, HEIGHT=400;
public Frame(){
super();
super.setSize(WIDTH,HEIGHT);
super.setVisible(true);
[Code] ....
In my main class I am just creating the frame and the panel then adding the panel to the frame.
My panel named panelIncomeInfo are not showing the components that I have added.
public class PayrollGUI {
private JPanel panelIncomeInfo = new JPanel ();
private JPanel panel = new JPanel ();
private JPanel panelPayCheckInfo = new JPanel ();
private JButton close = new JButton ("Close");
[Code] .....
I've been trying to draw a panel on a frame with simple drawString drawRect and oval but when i run it the frame shows up with the exit on close stuff but nothing will show inside . this is my code :
import java.awt.Graphics;
import javax.swing.JPanel;
import javax.swing.JFrame;
class Draw extends JPanel{
public void paintcomponents(Graphics g){
super.paintComponent(g);
g.drawLine(10,15,20,30);
[Code] .....
I'm not sure what's wrong , probably something to do from this pc ? since in the lab work at uni it worked fine .
My program has a MainFrame(extends JFrame)class and BasePanel(extends JPanel) class,and many other panels.I had used Images with JLabel in BasePanel.My current panel in MainFrame is BasePanel.I had used MouseListener so that when I click on any of the label it should show Other panel in same MainFrame and hide the BasePanel.But I am getting some problem with that.When I click on the Label,It hides the BasePanel but do not show the new Panel(Dictionary Panel in my code). In short when label is clicked I want to make DictionaryPanel visible and BasePanel invisible,both in MainFrame. I am using the following code on Label:
//constructor of BasePanel class
public BasePanel() {
dict=new Dictionary();
mf=new MainFrame();
dictLabel.addMouseListener(new MouseListener() {
public void mouseReleased(MouseEvent arg0) {

I have a Single Frame Application and I simply want to prompt the user with a dialog confirming they really want to close before they actually close the program, specifically when they click the X in the upper right. I THOUGHT it was like any other java application, with the slight added complexity of having to target the program-created-JFrame with: ".getApplication().getMainFrame()".
MyApp.getApplication().getMainFrame().setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
With that code, DO_NOTHING_ON_CLOSE is set on the JFrame, yet the program closes anyways. Which I don't understand.So I did some reading and found this: URL....That lead me to the configureWindow override, where I successfully tried this:
root.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
// write your code here
System.out.println("Window Closing");
}
});
But as far as I can tell that will only let me react to the window closing, not to the command to close it, where I could then kill the command in the dialog if they so "no I'm not ready to quit yet", if that makes sense. So, how to give a prompt before closing?I am using netbeans IDE to create this app - not sure if that is relevant, since maybe it is an oddity with the IDE and not Single Frame Applications.
I am writing a ComputerBaseTest application with Netbeans. I have each question on a panel and I want the questions(panels) to be switched, viewing the previous and the next question on a single frame, but I do not know how.
I only understand frame switching if each questn is to be on a frame but each score on each question (frame) do not sum up to give the overall score at the end of the test. Using multi-frame shows a sign of bad programming.
I am building a GUI application which consists of two panels "panel" and "panel1". "panel1" have a button "addTimer" when clicked it should add the "panel" to the frame if i gain click the button it should again add the "panel" without overlapping the previous "panel" rather it should be created below the previous "panel". If i click on the button "addTimer" n times it should add the panel n times. Along with this the frame size has to dynamically change depending on the number of panels produced. Below is the code i tried my level best to satisfy the above conditions.
package superTimerV2;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class SuperTimer extends JFrame {
private static final long serialVersionUID = 1L;
[Code] ....
In a project I'm ivolved in I have to dynamically add some components. All was going well until I had to generate data tables dynamically. I'm iterating a list of "SomeObject" and when I try to access a property of that object Glassfish tells me that object doesn't have such a property that is readable. I have getters for those properties and SomeObject implements Serializable as well. I used BalusC resources but I'm having no luck.

I want scrollbars to appear when the frame is resized and has components you don't see under so you can scroll down.
If I have for example this code, how i add the scrollbars when i make frame smaller ?

I want to have two threads running in my class, one will be downloading info from a website then putting the thread to sleep for a little bit, then repeating. The other will be sending information to a website then putting the thread to sleep for a little bit, then repeating. Is it possible to do this in my main class? I already have one thread using run() for downloading the info and sleeping can i make another?

View Replies View RelatedMy application depends on eight default user roles (or account types). They can be renamed or disabled, but should not be deleted. I want to protect them from deletion using their uuid value from the db. How can I pass their uuids into a single variable so I can use that single variable in my conditional statement? If I should use an array, any example of how I might do this?
View Replies View RelatedThis particular program is supposed to prompt the user to input either an uppercase or lowercase Y to process a phone number, they are then prompted to enter the character representation of a phone number (like CALL HOME would be 225-5466), this repeats until the user enters something other than the letter Y. All of the words entered are to be stored into a single array. The program is then to convert these words in the array to actual phone numbers. Here is what I have so far.
import java.util.*;
public class Program1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String begin;
int phoneNumber = number.convertNum();
[Code] ....
I realize that the second method doesn't have anything to return yet, I just wanted to put that in there while I was doing things that I actually know how to do ha. The convertNum() method is supposed to be the method with which the array of characters is converted to phone numbers.
I'm still trying to think my way through this. I would think it'd be easier to store the inputs from the user as individual letters rather than words for the sake of converting to phone numbers.
Also, we are only supposed to recognize the first 7 letters of each word that is entered, like the CALL HOME example, there are 8 letters but it's still a seven digit phone number, so I'm not sure how that would work.
Also, when printing the phone numbers after they've been converted, we're supposed to print the hyphen after the third number, I have no clue how that would be done from an array.

I have got a pretty good framework working for my hangman game so far, however I am quite stumped on how to find multiple instances of the same letter in a single string. I am using indexOf to find the instance of a character in a string, but it only returns the first instance. So if the words(s) contain(s) multiple instances it doesn't register the rest.

String word = "crazy horse";
String answer="";
