Adding A JButton From One Class To Another

Apr 25, 2014

I'm just learning JFrame and the like, I have 3 classes. I have one class that just calls the methods from the other 2 classes (my superclass), I have one class that draws a frame and adds a panel and then I have my 3rd class, where I'm trying to add a button from in the class to my panel in the other class. However it won't add the button. I'm sure I'm making some obvious mistake, as I'm quite new to Java, but I've been messing around with it for ages and I can't fix it. I'm also not sure if Frame should be extending Test or not.

import javax.swing.*;
import java.awt.*;
public class Test
{
JPanel panel;
JButton button1;

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);

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.*;

How To Change Action On 2nd JButton Click

Aug 3, 2014

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;
