JComboBox - Color Coded Table
Apr 27, 2015
I have a colour coded table, the JComboBox has items that are also colour coded to correspond to the colours on the table.
My ComboBox contains:
comboBoxSFMotor.addItem("Select a Value");
comboBoxSFMotor.addItem("Electric");
comboBoxSFMotor.addItem("DC Shunt");
comboBoxSFMotor.addItem("Combustion");
How can I set a background colour for each of the items in the JComboBox that will correspond to the table so that the user can make an easy selection?
An example of the table is attached

I am creating a JSP page with a html table to display employee directory. This is scriptlet :
<%
List<Employee> list = new ArrayList<Employee>();
PhoneListController controller = new PhoneListController();
list = controller.getAllContacts();
for (Employee eachEmp : list) {
%>
and then i display the table rows and columns for each employee object(PS: I know scriptlets are bad and obsolete but this is my first individual project.)
I would like to change the background color of certain rows based on value of one particular value(based on eachEmp.getManagerCode).
How can i achieve that by using javascript? I tried to call a js function by calling onload event on . But as I need to check for each row that is not the possible solution. I have not tried jquery yet as I am very new to jquery and I didnt quite understand how to do it in jquery.

No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK);
scene.setFill(Color.BLACK);
scene.setFill() worked fine for previous versions of JavaFX.

I've just started working on a program and i'm already having difficulties with the program. I can't get the background color to change from the basic gray color. Maybe you can tell me what i'm doing wrong.
import javax.swing.JFrame;
import javax.swing.WindowConstants;
import java.awt.*;
import java.lang.Object;
import java.awt.Color;
public class FrameDemo{
public static void main(String args[]){
Toolkit toolkit = Toolkit.getDefaultToolkit ();
[Code]...
also if theres any way to shorten up what I have there, that would be great.

How to define Cell in the table by table event?
I need to process one component drag to the table. I misunderstand, how I can see to which Cell fall the component. I tried to use Event and Mouse event handlers in my custom Cell, but they do not work. I can copy the drag event to the table and table handles it, but how to get needed Cell I cant understand.

I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).
In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...
However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.
Here is what I have tried:
private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross
if(cube.bottom.square[1].charAt(0) == topColor){
while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){
rotateBottomClockwise(1);
System.out.println("Trying to align side color...");
[Code] .....
The print out of the ELSE IF is:
alignment is: W-G and tops: R-R
NOW ITS ALIGNED
even though the sides, index 4 and 7, are NOT aligned with each other
I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.
Here is how it prints out
** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube
** ** ** R6 W5 O4 ** ** **
** ** ** R3 W2 O1 ** ** **
B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube
B2 G5 R8 W4 R5 Y6 O2 B5 G8
O7 W8 R9 B7 B8 B9 R1 R4 R7
** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube
** ** ** Y2 Y5 Y8 ** ** **
** ** ** B1 G6 W7 ** ** **
** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube
** ** ** R2 O5 G2 ** ** **
** ** ** W1 W6 G3 ** ** **
Here is the cube showing the top, left and front side
Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.
I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2

I am trying to set some serial port parameters here:
public synchronized void connect(String port, String rate, String data, String stop, String parity) throws Exception {
CommPortIdentifier portIdentifier = CommPortIdentifier.getPortIdentifier(port);
if (portIdentifier.isCurrentlyOwned()) {
System.out.println("Error: Port is currently in use");
} else {
CommPort commPort = portIdentifier.open(this.getClass().getName(),
2000);
[Code].....
To set the serial port parameters i need to use Integers instead of strings.
So, how i turn my string EG:
String[] baudRates = { "2400", "4800", "9600", "14400", "19200", "38400", "56000", "115200" };
into Integers for my combo box

I'm having an issue with using a JComboBox to select an item from a parallel array and displaying the correlating results in the same frame. Essentially, I have to add seven cities to a JComboBox drop down within a frame, select a city then display the population of that city in the frame with a label indicating the population. I have two issues:
1) my label text will not show up during execution unless I drag a corner no matter what width or height I make the frame.
2) I need to make the JComboBox selection correlate to the city population and display as a label, not having making that work using the getSelectedIndex() method.
I think I need to add an event listener for the combobox selection, not sure where to add that if that is the case. Here is my mess so far:
import java.awt.FlowLayout;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JComboBox;
[Code]....

I'm trying to populate my JComboBox with an Arraylist. Using two different classes, a GUI class (with the JComboBox - called it MainGui) and a class where I extract information from a database and put it into an ArrayList (which I call databaseconn).In my databaseconn class, I can print out the content of the ArrayList perfectly fine, but when I try to do it in my GUI class it just prints empty brackets "[]".(What I need it to do is to populate the drop down list in the JComboBox with the hotel information).Here's my code:
//The dataaccesslayer you should use for classes that deal with connection to the database
package dataaccesslayer;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;

I recently posted that JComboBox should be used in a generic manner. I presumed that once declared, with some type Foo, that one could then do:
Java Code:
JComboxBox<Foo> cb = new JComboBox<>();
// sometime later
Foo foo = cb.getSelectedItem(); mh_sh_highlight_all('java');
However, getSelectedItem() is documented to return a type of Object so a cast is still needed. I can't understand (even for backward compatibility) why it doesn't return a type of the specified type. Many other old classes have been converted to generics so why should this be any different? I just found that one could use getPrototypeDisplayValue() but that seems counter intuitive.

I have a student class with fields names and Gender. Now, I have a students' array. such that I can create multiple students' classes: student a, student b, student c e.t.c and store them into the students' array. Now, I store this students' array in a JComboBox and want to only display the names of these students in the array. Such that the JComboBox lists only the names of student a, student b and student c. . When a user clicks on a selected Item on the JComboBox, even though, it was a student's name that was selected, I want the selectedItem to be a object of the Student class. This, I have learnt works with JList by writing your own custom JList models and then DefaultListCellRenderer. Is there anyway, one could also do this with JComboBox?

import StudentList;
import Student;
