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.
View RepliesI'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.

ImageIcon iconThr = new ImageIcon ("bat.jpg");
ImageIcon iconFou = new ImageIcon ("baseball.jpg");

I've tried multiple things but I can't seem to figure out how to get my JButton over the background graphics. On lines 104-108 I create the JButton I need to put on the screen, though I have no clue how to draw it. How I can paint over this background and have my button stay there?

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.

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.*;

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 read the oracle doc example, i understand the concept but still nothing is happening on show,first ,next method of CardLayout in ActionPerformed. Code is highlighted where I am facing problem.
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.
I'm currently trying to do a diamond using Polygon. I have done this so far. It is not drawing a diamond.
import java.applet.Applet;
import java.awt.Graphics;
public class Diamond extends Applet {
int[] a = {-30, 100 , 30, 100};
int[] b = {100, 40, 100, -40};

public void paint(Graphics g)

g.drawPolygon(a, b, 4);

I currently have the code set up to iterate through objects and keep track of them but how do I do the same and draw the objects on the panel window? I'm confused on what to do and how to start it.
Here's the code I have so far, the 'Car' which I want to draw extends to another class which extends to GameObject. I currently have a 'draw()' method under the 'Car' class but nothing in the 'draw()' method yet. From what I understand i'm suppose to have a 'draw()' method under 'GameObjects' class also?
public class MapView extends JPanel implements IObserver, ActionListener{
JPanel myPanel;
private Timer timer = new Timer(5, this);
int x = 0;
int moveX = 2;
public MapView(){
super.setBorder(BorderFactory.createTitledBorder("Map:"));
[code]....
Mostly I don't understand how to go through the iterator again to paint the objects. Wouldn't I need to put another iterator under 'paintComponent()' or can it be done under 'update()' ?

I'm having trouble in 2 areas.
I'm trying to draw 3 triangles 'on top' of each other to give appearance of a tree. My code is below and struggling with how to set my x/y cords correctly.

Simple gui task. it meant to draw pie chart with different colors. i can't seem to find a mistake in it. It works if i put in g2g.draw(arc) i know arcs overlaps a bit due int conversion, but that's ok.

View Replies View RelatedI have a Jbutton in my application named as SUBMIT,on clicking SUBMIT the text of jButton changes to ABORT. I wish to apply enter key listener on both the SUBMIT and ABORT button in my applcation, however I am not able to get the text of the button in key listener,so that i can apply my code based on the current text of Button.
View Replies View RelatedI 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

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?

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...

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;

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.
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?
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.
