Swing/AWT/SWT :: What Are Parent And Child Components
Aug 11, 2014I keep hearing these two term when it comes to painting in Swing, however, I'm not sure which is which. To my understanding is that the child components are the ones that already exist on screen (could be a JButton, JFrame, or custom painting) . and the parent components are the one to be added/drawn next. (hence, if we override the paintChildren() method when painting, the components that were already on the screen don't appear any more).

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.
Swing/AWT/SWT :: Progress Bar Dialog Sometimes Doesn't Display Components
Mar 7, 2014I wish to display a progress bar during a lengthy file translation process. When I created a ProgressBar class to do this and tested it with a short test program, it seemed to work fine. But when I add my ProgressBar class to a package containing various other classes, put that package in a jar file, and then execute the class using the progress bar from a menu in my main program, the frame of the progress bar shows up with the appropriate caption but the JLabel, JProgressBar, and JButton are not displayed. I have gone over my code numerous times and checked that the ProgressBar class constructor is getting the proper arguments.
// package gov.nasa.jpl.ephemeris;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
/**
* Progress bar with message text above the bar and a Cancel button below it
*/
public class ProgressBar extends JFrame {
private boolean _cancelled = false;
private JProgressBar _progressBar = null;
[Code] ....
I have also been wondering whether I need a separate instance of the border for each panel, or whether I can just create one instance and use it for all three panels.
Swing/AWT/SWT :: Simplest Window Possible

View Replies View RelatedSwing/AWT/SWT :: Displaying PNG In A Window
Jan 31, 2014That's my third day working in Java using Swing and the IntelliJ Idea IDE.I'm trying to do something as simple as displaying a PNG in a window, and I'm doing this:
public class AboutRapide {
public JPanel mainPanel;
private void createUIComponents() {
mainPanel = new ImagePanel();
[cod]....
the problem is that, in the paintComponent method, the Image is never found when I run my app from the IDE, but it is when I run it from Finder in my Mac. Same application. I think it relates to how the application is launched so I guess what's a proper way to refer to a resource file with an image so it can be displayed no matter how the application is launched?Also if I generate a Jar for the application, as the resource gets into the Jar compressed file, it can't also be loaded.
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.
Swing/AWT/SWT :: MouseListener Doesn't Work If JList Has Custom CellRenderer
Nov 9, 2014I have a JList<Object> in my code (it actually takes JLabels) called imageList, and I've given it a custom CellRenderer using the following code:
cellRenderer = new DefaultListCellRenderer() {
private static final long serialVersionUID = 1L;
@Override
public Component getListCellRendererComponent(JList<?> list,
Object value, int index, boolean isSelected,
boolean cellHasFocus) {
[Code] .....
However, when I click anywhere on the JList, nothing gets printed to the console, which suggests that the mousePressed() method isn't being invoked. I think it's a problem with the CellRenderer, because I have similar code elsewhere that works, the only difference being I don't use a custom CellRenderer.

Method To Wait On Different Swing Window?
Dec 20, 2014I am trying to create a gambling POS system and having problems with a method trying to get a value right after it was set. A jbutton sets another jframe visible which contains buttons. Upon action of the button, a value is set and the jframe is disposed.
private void btnPrizeActionPerformed(java.awt.event.ActionEvent evt) {
PrizeSelling prize = new PrizeSelling();
prize.setVisible(true);//create prize selection window
bin = getButton(); //gets what button is selected to load the correct prizes for correct game
prize.DBconnect(bin);//sends bin number to prize loading method
[Code] ....
As soon as btnPrize is clicked it gets the total value of the prizes selected which of course is 0 because it is ran before it is set. How can I make it wait until the window is closed before continuing?

Swing/AWT/SWT :: JButton Opening New JFrame In New Window

View Replies View RelatedSwing/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) {

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 :: Getting Icons To Change Size With Window Resize
Jan 19, 2014I'm using a jpanel with an 8 by 8 grid layout of jlabels to which I'm adding images to represent a chess board. At first, I was using the ImageIcon class to initialize my icons, but as soon as I added these icons to the labels, the labels no longer changed size with the window (which I want to happen). URL...
So I copied in the class, and initialized a different set of icons using the stretch icon class (specifically, the method that allows you to initialize a stretch icon from a filename), however, when I use these stretch icons, the result is the same. Is something wrong with the class, or with my implimentation of it, and how would I fix this?
