Swing/AWT/SWT :: JFrame Using Layered Panels With MigLayout
May 23, 2014
The question is when I hit the maximize button on the JFrame my panel instantly goes to the top left corner of the JFrame. Is it possible to center the panel inside the JFrame, when the maximize button is pushed? I am familiar with push and grow that MigLayout uses but this isn't exactly what I need. I don't want several textFields to span the screen. Instead I would rather have the panel centered.
This is just a sample project to test out the MigLayout API

Is it good practice to create a inner class for layered panels with lots of components? In my opinion this makes the code easier to read and a lot less clustered.

I have been trying to create a chat client which makes use of a scrollable jpanel and at runtime adds JTextFields to the panel.
Panel Initialising
msgPanel = new JPanel(new MigLayout());
msgPanel.setPreferredSize(new Dimension(400,335));
JScrollPane msgPanelScroll = new JScrollPane(msgPanel);
msgPanelScroll.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
msgPanelScroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED);
mainPanel.add(msgPanelScroll,"span 3,alignx center,wrap");
[Code] .....
But now Im facing the following issues. The text field aligns to the center of the panel & on adding more fields the panel accommodates as it can and does not begin scrolling.

With the MigLayout for Swing, I'd like to see the JDialog looking like the standard windows Dialog,where to have the OK and cancel buttons at the lower right corner.

I cannot get my panels to appear in my GUI when I run my program. There is probably a really simple fix for this but it is taking me hours. This program is a working progress and I have just included two classes out of five. That should be adequate to diag my problem.
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class OrderCalc extends JFrame
{
private final int WINDOW_WIDTH = 200;
private final int WINDOW_HEIGHT = 200;
[Code]...

I wrote the following code to get a frame,button in south and a red color circle,which i got.In the "actionPerformed" method i wrote "setContentPane(mp2)" thinking it would put another panel on the frame with a blue circle but when i pushed the button,the button got stuck and the circled did not change.
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Fra implements ActionListener
{
MyPanel2 mp2;
JFrame frame;
JButton button;
public static void main(String[] args)
[Code] .....

one of the java swing challenge I am facing. Problem statement: there are two JPanels panel 1 and panel 2 placed on a JFrame one below the other as panel 2 below panel 1. Now, I need to put a JButton in any one of the panels such that this JButton displays half in panel 1 and half in panel 2.

I'm having trouble with this program. In my textbook it says "Write an application that displays a frame containing two panels. Each panel should contain two images (use four unique images - your choice). Fix the size of the first panel so that both of its images remain side by side. Allow the other panel to change size as needed. Experiment with the size of the window to see the images change orientation. Make sure you understand why the application behaves as it does". I successfully imported the images, but I can't find out anywhere how to allow the second panel to change size with the window.
import java.awt.*;
import javax.swing.*;
public class TwoPanels
{
public static void main(String[] args)
{
JFrame frame = new JFrame ("Embedded Images");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
ImageIcon iconOne = new ImageIcon ("glove.jpg");
ImageIcon iconTwo = new ImageIcon ("cleats.jpg");
ImageIcon iconThr = new ImageIcon ("bat.jpg");
ImageIcon iconFou = new ImageIcon ("baseball.jpg");
[code]...

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.

These are layered panes and I am using netbeans 8.0. The textfields of the lower panes come out in the pane above them when I ran the program.

Is there a way to simply slap a rectangle into a JPanel (make it appear) with out creating an inner Class or helper Method, all within "Main"? And if not, why?
Making a JFrame is easy.
Adding a JPanel is a snap.
import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class TheJFrame {
public static void main(String[] args) {
// TODO Auto-generated method stub

I have a Jframe and i want to add inside 4 different jpanel.This is easy.
what is difficult is how can i change them dynamically with 4 other new jpanels and 4 other new jpanels?
I have try with BorderLayout but not working.

All I need to do is show in just one JFrame the two combined JFrames. One JFrame namely leftPanel will appear to the left or west and the other namely rightPanel to the right or east using BorderLayout. I already did creating them first as JPanels or as internal classes and subsetted them in one JFrame but that didn't work because it looked messy. And now I've created them as two separate JFrames, compiled separately, and tried to subset them as one in the JFrame. I didn't add any functionality to this program because all I intend to do is to show those two JFrames together in one JFrame. Here's the code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class dirtyIceCream extends JFrame {
leftPanel westPanel;
rightPanel eastPanel;
public dirtyIceCream()
[code].....
What am I missing or did I code anything wrong here? Or should I use NetBeans IDE for anything as complicated as this?

I am rather new to Swing, and I am building a game right now in which I need to display a pop-up window as a reminder for what commands exist within the game. I created a class extending JFrame for this and added all the information I need. However, for some reason, no matter how many different ways I try to set the size of this window (setSize(w, h), pack(), using a different layout, adding the compnents to a JPanel first and setting the preffered size of that, then adding the JPanel to the JFrame), it doesn't work. Instead of a window of my requested size, I get a tiny, maybe 100 x 100 pixel window that needs to be resized in order for its contents to be visible.
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.GridLayout;
import java.awt.Toolkit;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

I need to put a Web Page in my JFrame application , I got a lot codes on the internet and could implement without problems , but the problem is that this code has an ugly page as hell, with colored all wrong and with a very poor quality , one of code I used was this :
* import javax.swing . ;
{ public class SwingWebPage
public static void main ( String args [ ] ) throws Exception {
JEditorPane website = new JEditorPane ( " http://www.google.com/ " ) ;
website.setEditable ( false) ;
[code]...
If you test , you'll see that the page is displayed in the JFrame is horrible.

I am try to do an application based in multiples JFrames, each one with its particular responsibilities, and use one JPanel as a menu with buttons that connect one JFrame to another, But this menu is instantiated at run in view (layout made by netbeans) the Main Jframe appears with its internal JPanel, but the instantiated JPanel does not appear or does not show it's buttons.

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 {
