Swing/AWT/SWT :: Scrollable JPanel Using MigLayout

Dec 28, 2014

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.

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

Swing/AWT/SWT :: Factory Design Pattern With Swing JDialog

Jul 26, 2014

Is 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 :: Allow JDialog To Resize Larger But Not Smaller

May 16, 2014

Lets say the JDialog opens 5x5. The user is allowed to modify its size to be any size larger than 5x5 but is not allowed to make it smaller. Is there such a property or will this have to be regulated via code?

Swing/AWT/SWT :: Program Doesn't Close Through JDialog Box

Mar 30, 2014

I 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 :: JButton Does Not Do All Tasks

Aug 3, 2014

I have a jButton that when the action perform runs it only does part of the tasks some of the code doe not appear to run and i just can not figure out why i have tried wrapping parts of it in an if statement and it still do not run so here is the code behind the button:

in the code the parts that do not run are jTextField10.setText("Working Please Wait"); and jButton15.setVisible(false);

what i am expecting to happen is the text field has the words Working Please Wait placed in it , this does not happen and the button should be hidden to prevent it being clicked a second time again this does not happen

the rest of the code works as expected

InputStream inStream;
OutputStream outStream;
try {
File afile = new File("C://templates//amendments.xls");
File bfile = new File("C://amendments.xls");
inStream = new FileInputStream(afile);
outStream = new FileOutputStream(bfile);

[code]....

Swing/AWT/SWT :: How To Show A JButton

I'm not sure what I'm doing wrong but none of the buttons will show below. I tried using .add with the container name but it kept giving me an error. When I just put add.(); it seems fine but then nothing shows. Is there something I'm missing that's required?

import java.awt.Container;
import java.awt.FlowLayout;
import javax.swing.JButton;

Swing/AWT/SWT :: JButton Actionlistener Not Working?

Mar 5, 2014

I was suspecting I had a jButton not working, so I added a console print to test. See below. When I click the button, the console doesn't display anything. Am I using the button wrong?

private void jButtonUpdateItemsMouseClicked(java.awt.event.MouseEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}

I have also tried the following with the same results (or lack of).

private void jButtonUpdateMajorDeckItemsActionPerformed(java.awt.event.ActionEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}

Swing/AWT/SWT :: Setting Icon On JButton

Feb 23, 2014

Recently I have been working on an executable launcher. I tried to get the executable icons and set them on the JButtons. Still there are some problems. Here is a part of the code:

try {
button[i].setIcon(FileSystemView.getFileSystemView().getSystemIcon(new File(getConfig("path." + (i+1)))));
}
catch (NullPointerException ex) {
}

Here the getConfig() method is already defined to get a string in a "properties" file. However, the icons are very small and they don't fill the entire button.

How can the icon fill the entire button (for example, having a custom size of 48x48, or automatically filled the button)? The frame will not be resized.

Here is the whole code...

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.io.File.*;

[Code] ....

Swing/AWT/SWT :: How To Change Action After 1st JButton Click

Aug 3, 2014

I am relatively new to java. . I cannot...(actually do not know) how to change the actionlistener (actionPerformed) after the second click in an array of JButtons. This is how the program performs right now.

On the 1st click on the grid, the border of the button clicked will change to 'blue' and another button will change its boarder to 'red'. on the next click the same action is performed.

What I need is to change action when the 'red' bordered button is clicked, lets say change the color of the buttons from the 'red' to the 'blue' buttons.(x 3 buttons).

The logic about how to perform the final result I think I can do on my own but my problem is how to change the action when the red bordered button is clicked.

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.BorderFactory;

[Code] .....

Swing/AWT/SWT :: Search For A Key In Properties File - Jbutton Won't Work

Aug 26, 2014

I have a properties file with key values in it, now when I use my search box to search for a key in the properties file to check whether or not it is there - I can't get it to check and return the key value if it is theere. I've tried a few methods but keep getting a null pointer exception when it hits line 15 in the code all the time so I'm stumped at the minute.

My text field is called textFieldSearch

This is my button code

JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//search button
//find selected comman
String key_name = textFieldSearch.getText();

[Code] ....

This is my method code

public void FindSelectedKey()
{
if(textFieldSearch != null)
{
properties.getProperty(key_name == textFieldSearch)
}
}
