JavaFX 2.0 :: Determine Which CombBox In A Pane Has Been Clicked?
May 14, 2015
I have a pane with numerous comboboxes. Each ComboBox must perform an action when the mouse button is clicked on the ComboBox (OnMouseClicked). I have written a function that operates on a particular ComboBox, but I want to generalize it to operate on any of the CombBox objects clicked. I think the function should resolve the CombBox object within the function itself, and perform the operations on that ComboBox. But, I don't know how to get the ComboBox from within the function itself.
I have tried viewing the ComboBox documentation, but there doesn't seem to be a method that lets a clicked ComboBox notify the OnMouseClicked action which ComboBox has been clicked. How I go about identifying the clicked ComboBox within the OnMouseClicked function?

I want to have a button that will include another node beyond the text and image that are part from the Button. This node as example will be a circle that I will change his color from gray to green if the button was pushed.
I try to do this with Background / BackgroundFill with no success
I tried to get access to the Pane / Region of the Button, but I can't find a way to do it.

I am struggling to get a way to click within a Pane and select a Line. The Line has been drawn by the user and there can be numerous.
For example if you select a Vertex I can just ask if it contains the point. How would you do this for a line?

We needed to use a GUI via JOptionPane with our program. So that we may turn out programs in as executable jar files. However, I have never used it. Here is my problem and code:
package waitingroomlinkedlist;
import java.util.Scanner;
import javax.swing.JOptionPane;
public class WaitingRoomLinkedList {
public static void main(String args[]) {
boolean done = false;
String inputFirst;
String inputLast;
String[] choices = {"First Name", "Last Name", "Quit"};
[Code] ....
Now for some reason I am getting an error when trying to create a new instance of the Person class and pass inputFirst and inputLast. Its telling me that I have not initialized inputFirst or Last. When I allow it to initialize it sets inputFirst = null; and so forth with inputLast. All I want to do is pass the two Strings to my constructor in my Person class.

while using JOption Pane. So my output for the code is correct, however, it keeps repeating the dialog.
public static void main {
String y = "";
String aString;
int a, sum;
double average;
int count=0;
[code]....
My output for the first input ends up like this:
You have enter 1 as integer.
Sum = 1
Average = 1.0
So far so good....however when I add another input.
You have enter 1 as integer.
Sum = 1
Average = 1.0
You have enter 1 as integer.
Sum = 2
Average = 1.0
What I want is the You have enter, sum,average to show up once while still adding sums and average.I tried moving string y out of the while loop and used if statement but to no avail.

The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. The content pane is supposed to be a scroll pane, however no matter how much I type into the editor, the scroll bar does not appear. Also, the none of the functions under the "Edit" menu work.
Java Code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.io.*;
import java.util.*;
import java.util.StringTokenizer;
import java.util.regex.Pattern;
/**
* A simple text editor. It creates and displays the GUI Text Editor.

public class TextEditor extends JFrame implements ActionListener

I am using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly. I have attached the java file

I'm new to java and I'm currently trying to make a program that uses a JTree that implements a properties file. I have the Keys set to the nodes but I want it so that when the node is clicked it will retrieve the keys value from the prop file.
I did have some code for this initially but I as it did not work at the time and was causing issues to my project I got rid of it. I have my code for the jtree,the listener and the prop file.
Tree
Java Code:
JPanel panel_1 = new JPanel();
panel_1.setBackground(Color.WHITE);
panel_1.setSize(new Dimension(22, 0));
scrollPane.setViewportView(panel_1);
Properties properties = new Properties();
[Code] ....

Is there a way of doing this? Been trying for a while now but to no prevail. The image is what it currently looks like

I have a question and wasn't able to find what I needed through the search. I am currently using Netbeans 8.0 and working on a desktop app. I have a main GUI file where I am going to add a menu item that can be clicked to open up an "About" Dialog box. The problem is, I don't know how to do this
The file are...
MainGui.java
About.java
How would I go about opening the About.java when clicking on a menu item? I tried using...
new About();
About.setVisible(true);
But this just gave a compilation error.

I'm working on an applet for my class. I decided to use AWT even though it's really old.
I'm having trouble with the labels on my program. They don't show up until I click another tab in the browser and then go back to it each time after I click on a button. I tried to use repaint() but it doesn't seem to work. What can I do?

import java.awt.event.*;
import java.awt.event.ActionListener;
import java.awt.color.*;
public class FinalTwo extends Applet implements ActionListener{
Button b1;
Button b2;

What it's supposed to do: This code is supposed to see if the clicked card is selected. If it's not, select it and show the player where it can move / attack. If it is selected, then find out what card the player clicked on. If he clicked on the card that was already selected, deselect it. If he clicks on a friendly card (same playerID), then select that card. If he clicks on an enemy card (different playerID), attack that card. If he clicks on a tile, move it to that tile.
The problem: However, line 24-58 give me a bit of a problem. Right now, it works fine BECAUSE lines 46-58 are commented (which also means the unit can't move). If I uncomment those lines, the unit becomes able to move, however, lines 34-46 cease working...
Java Code:
@Override
public void mouseClicked(MouseEvent e) {
mainloop: for (int i = 0; i < Main.cards.size(); i++) {
Card c = (Card) Main.cards.get(i);
if (Card.cardSelected == null) {// Contains / Is not selected
if (c.contains(e.getX(), e.getY())) {
Tile.reset();
Card.reset();
Card.cardSelected = c;

I'm working on a spreadsheet-like table and I was able to set it so that it would highlight the first cell in the relevant row(titled 1,2,3.. etc) when a cell is clicked. (Just like in MS Excel - preview attached) Now I want to do the same to the column header(i.e. A,B,C,D....etc) . How can I do it?
private void formWindowOpened(java.awt.event.WindowEvent evt) {
setLocationRelativeTo(null);
int rowNum = sheet.getRowCount();
for(int i=0; i<rowNum; i++){
sheet.setValueAt(i+1, i, 0);

This is an old project that I had working probably 2 years ago. Since I reopened it the only thing I have changed is the database location. This is a very basic project I did to dip my toes in to Java. I'm going to add it to my portfolio but just to clarify I am not a Java developer so this is mainly there to show that I am not completely blind when it comes to Java.
//Import libraries
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.GridLayout;
import java.awt.event.KeyEvent;
import java.math.BigDecimal;
import java.math.RoundingMode;
import java.sql.Connection;
import java.sql.DriverManager;
[Code]...
Errors when I click the button that launches the JFrame:
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 6 >= 6
at java.util.Vector.elementAt(Unknown Source)
at javax.swing.table.DefaultTableModel.getValueAt(Unknown Source)
at javax.swing.JTable.getValueAt(Unknown Source)
at javax.swing.JTable.prepareRenderer(Unknown Source)
at javax.swing.plaf.basic.BasicTableUI.paintCell(Unknown Source)
[Code]...
It will launch the window but it will be blank. If I resize the window it will show me the headers. If I click below the headers were the data should be, it will show me the data.
Since it has been so long the only thing I can think of is some of the code has become antiquated. As I said, this was working originally. I just fired it up again to take some screenshots for my portfolio.

<c:set var="catList" value="${category.categoryList}" scope="application"/>
</c:if>
<div id="categoryBrowse"><label>Browse by Category</label></div>

It works fine. But every time I click on a link on the menu, it duplicates the whole menu.
