Swing/AWT/SWT :: JButton Opening New JFrame In New Window
Oct 14, 2014
We are creating a quiz as a school program, we are using netbeans and we have a little problem. The problem is that our JButton opens a new JFrame in a new window and we want it to stay in the same window. The code we are using is:
private void PlayButtonActionPerformed(java.awt.event.ActionEve nt evt) {
Question1 s = new Question1 ();
s.setVisible(true);
}
Is it possible to make it stay in the same window?

I am looking for a solution that will allow me to use a custom background image to replace the JFrame window. I am able to add a background Image, however I am not able to remove the "white" that is supposed to be transparent.
For example; if the image was shaped like a bird with transparent background (.PNG), I would like that to be put on the JFrame. Usually it will be a square with the image in the middle with white background, which I am unable to remove.

how to put a console on a JFrame or on graphics window. I thought about simply using a JtextField however I don't have access to the readline command since it appears to me that it is only found in a Console Program. So basically I was wondering how to put up a console on JFrame so I can issue commands on it and watch graphical stuff happen on the same screen(minus where the console box is of course).

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]....

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;
import javax.swing.JFrame;
import javax.swing.JLabel;
@SuppressWarnings("serial")

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
}

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] ....

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] .....

what I have already tried:
to set the margin of a button - didn´t work
to set anything like padding - didn´t found something for java
to set an empty border - didn´t work
I don´t know what to try next.
My main problem is to enlarge the clickable area without resizing the buttons image.

how can i execute the main class into a JButton.
Example: Main Class
public class ComparativoV3{
public void loadComparative(String path){
}
public void compareDbs(){
[Code].....
how to set it up the private void CompareActionPerformed(java.awt.event.ActionEvent evt) as the ComparativeV3 main class, not giving it any argument, because the files are load from the arguments section & it reads diferent files with diferent arguments.

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)
}
}

That'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.

In JButton's click event, I wanto to show a JPanel to print the message "Processing" on the screen. Before JButton's click logic end, hide the JPanel.
Actually, JPanel is not displayed. I do not know why.When msgPanel .setVisible(false); is commented out, JPanel is normally displayed .But do not know how to hide it when JButton's click logic is finished.
Here is the code.
loadBtn.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
JPanel msgPanel = new JPanel(rootFrame);
// Show the message JPanel

Problem: On the form window, after pressing the button, it doesn't give any error and doesn't give any output. It doesn't reply and i have to stop compiling to exit. Why does the IDE do that, is it about my Java codes or Form Window codes ? ( I have two classes named Lexical.java and window.java. Working with Eclipse)
Details: I am working on a project that makes Lexical and Syntax analiysis of commands written in SQL Language. My form is in the attachment. If will be necessary i'll put my codes too.
