Swing/AWT/SWT :: Program Doesn't Close Through JDialog Box
Mar 30, 2014I have a practice exercise here wherein I will add a JOptionPane to a program. When the close button is clicked, the JOptionPane will appear asking the user to exit the program. If the user clicks "Yes," it'll, of course, close the entire program and not just the JOptionPane, but if the user clicks "No," it will return to the program. Please refer to my code below:
try
{
output = new DataOutputStream(new FileOutputStream("ProjSixExe4.dat"));
}
catch(IOException ex) {
this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING))
}
final JOptionPane optionpane = new JOptionPane("Are you sure you want to quit
this program?", JOptionPane.QUESTION_MESSAGE, JOptionPane.YES_NO_OPTION);
this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
The exercise said it must be placed before the EXIT_ON_CLOSE portion.

View Replies View RelatedSwing/AWT/SWT :: Factory Design Pattern With Swing JDialog
Jul 26, 2014Is it a good idea to use the factory design pattern for say if I needed to create four different JDialogs for the same parent frame?
factory design interface
package client;
public interface Dialog {
void getInstanceOf ();
void initComponents ();
}
One of the four JDialog class would look something like this without the comments.
package client;
import javax.swing.JDialog;
@SuppressWarnings("serial")
public class AddCustomerDialog extends JDialog implements Dialog{
public AddCustomerDialog () {
//Some stuff goes here to set the settings for JDialog instance
[code]....
Of course you would have your factory class

Swing/AWT/SWT :: WindowListener Not Being Called When Clicking X To Close Window
Oct 14, 2014I have added a windowListener to my JFrame but for some reason it is not being called when I click X to close the window. I need to send a message to a server to notify it that the client window is closed. Some code snippets below (some lines excluded for brevity):
public class ChatGUI extends javax.swing.JFrame {
....
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); // I have all the window constants here but has no effect other than closing the window without calling the listener...
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosed(java.awt.event.WindowEvent evt) {
formWindowClosed(evt);
}
});
....
private void formWindowClosed(java.awt.event.WindowEvent evt) {
[code]....
This is resolved, needed to use...
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
formWindowClosing(evt);
}
});
... instead.
Swing/AWT/SWT :: How To Return Values From A JForm To The Main Window On Close
Jan 26, 2014I am making a java swing program. I have a main window that opens a JForm window when the user clicks a menu option. Then I have a button on the JForm that closes the window on click. However, I would also somehow like to make the JForm return values to the main window (according to the states of the selector components) when it is closed. How would I go about this? Currently my jForm is a seperate class called "NewGame", and inside the menu item mouse clicked method, I have the following code:
//open new game jform window
NewGame newGameWindow = new NewGame();
newGameWindow.setVisible(true);
newGameWindow.setLocationRelativeTo(null); //center window
Is there something I can add here to get the object's values upon the window's close? Or is there a way I can add that into the button clicked method on the actual jForm?
Swing/AWT/SWT :: Program Doesn't Close Though WindowClosing Event Called
Mar 25, 2014I use the right term, release resources because after clicking the close button, the DOS prompts becomes unresponsive. So I have to close the DOS prompt, then reopen it, then type in the path again for the Java folders. Can you check where did I go wrong with my code? Is my placement of the WindowListener and WindowAdapter incorrect? Please refer to my code below:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class Proj6exe1 extends JFrame implements ActionListener
{
DataOutputStream dataLabas;
JTextField rainFallField;
JButton submit;
String strRainFall;
JPanel proj6Panel;
[code]...
I have other programs where the placement of the WindowListener and WindowAdapter are as exactly like this (within the class constructor block) where they close correctly and some that behave like this, that renders the DOS prompt unresponsive.

Java I/O - If Stream Contain Nothing Then Close It
Jul 10, 2014For every stream that we create for java i/o we write at the end in finally block
finally
{
if(is!=null)
{
is.close();
}
}
It works
my question is as per syntax in if (is!=null) this means that if is means stream contain some value then close it(!=null)
then how it in my opnion it should be like (in logical way)
if stream contain nothing then close it
if(is==null)
{
is.close();
}
I am confuse about working this line
Mathematical Operation On Bytes

String To Math Operation
Sep 14, 2014Given a string of numbers and operator. Compute as follows:
Consider, "000293000002030403+0400293059694" is the input.
a. Separate the two operands and one operator:
"000293000002030403" "+" "0400293059694"
b. On each string operand, take each digit. ADD them all.
(2+9+3+2+3+4+3) + (4+2+9+3+5+9+6+9+4)
The two string operands should now become two integers.
c. Lastly, perform the operation using the string operator specified on the original string.
26 + 51 = 77
I don't know why I get the sum of 52 when I use a for loop.
Here are my codes:
public class string2math {
public static void main(String[] args) {
String input = "000293000002030403+0400293059694";
String [] operand = input.split("+");
String firstOpera = operand[0];

Wait For External Application To Close
Jun 16, 2014I am writing a console application that is to make use of the system editor on *NIX. For that I have written a method which writes a string to a file, launches an editor to change that file, and then reads the file again. The problem is the call to run the editor doesn't wait for that application to have closed.

Addition Operation On Character Variables
Feb 8, 2015When addition operation is performed on the character variables ,then it specifies actually that the ASCII values are added because the character variable stores ASCII value of the character constant ,then why after the addition the result cannot be stored inside a character variable ,why it needs to be stored in an integer variable only ,when actually the character variable stores the ASCII value then why is it an error to store the added result in an character variable.
