Swing/AWT/SWT :: ComboBox For 50 States Using Array?
Apr 17, 2015This is what I need to create:This project focuses on demonstrating your understanding of GUI and event programming. Before attempting this project, be sure you have completed all of the reading assignments listed in the syllabus to date, participated in the weekly conferences, and thoroughly understand the examples throughout the chapters.
Enhance the form you created in homework 3 to add a JCombobox to select the user’s State of residence, and a group of JRadio buttons to indicate the user's gender. Once the user clicks on the JButton (created in homework 3) the application will display all of the user’s information in the JTextearea in a format similar to the following:
Name:
Age:
Gender:
Age Group:
State of Residence:
This is my code so far. I am having trouble with trying to select a state from my comboBox. My box prints out on the screen fine, but it will not allow me to select a state and print out a state. I was able to get the event listener to work for my radio buttons ok. But I am stuck on the comboBox.
import javax.swing.*;
import java.awt.*;

public class NameAge extends JFrame {
//Create text fields and labels

Swing/AWT/SWT :: Vector Is Used In ComboBox Model?
Sep 23, 2014I understand how vectors work I'm currently using one to store my id's from my txt file but how do you put them in a defaultComboBoxModel?
DefaultComboBoxModel defaultComboBoxModel = new DefaultComboBoxModel();
//declare a vector object that will hold a string (only thing that works with comboboxmodel
Vector<String> myVector=new Vector<String>();
//try statement
try{
FileReader fr = new FileReader(file);
[Code]...
Any example of how a vector is used with a defaultComboBoxModel so I can then use that to populate my JComboBox?

May 29, 2014I have a ComboBox I'm using for a cellEditor. The list of items in the comboBox might have colors behind them, which I've managed to render. What I haven't figured out is a good way to keep the color in the cell after the item is selected.I don't' want to have a persistent comboBox in the cell, i only want to see it when editing that cell.
public TableCellEditor getCellEditor(int row, int col)

JComboBox<?> combo = new JComboBox<Object>(getPickListEntries());
combo.setRenderer(new PickListRenderer(combo));

Writing If Statement With Combobox
Apr 11, 2014I'm working on assignment for a class where I'm creating a home utility auditor. Basically the user has to pick from a list of appliances and then input various fields to calculate a total cost. When the user chooses "washer" from the list of appliances, they must enter in values for 2 separate fields, and will then click calculate to get total cost. I've been trying to implement this through an if, else statement, but it's not wanting to calculate a total cost and I'm running into errors. I've put the code below.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// The calculate button will multiply the 3 fields that the user inputs:
//cost*Kw used*hours used=total cost of operation
float num1,num2, num3, result;
//now, parse the text to a type float
num1= Float.parseFloat (costField.getText ());

JavaFX 2.0 :: Combobox Inside A Tablecell
Mar 24, 2015I have a combo box inside a table cell for each row. I have defined a value change listener for each combobox. Whenever the combo box value is changed, the selected item is placed inside a MAPVOBean. The problem i am facing is when the user scrolls Up and down the tableview , the change listener is fired even without clicking on it the explicitly, and this changes the my value in my data structure. How to handle this. The source code is attached.
My Model:
Person class
Has first name, last name and MAPVOBean.
Address is stored in a MAPVOBean. It has a map and key is house number and the value is the state where the house is. It is assumed that the person can have one house in each state.
Columns in table view:
Column 1: First Name
Column 2: Last name
Column 3: State combo box. This shows the state in which the person owns a house.

JavaFX 2.0 :: ComboBox Caret Position
Feb 23, 2015I am developing a form with ComboBox as a subject (the user can choose one from the list , or type one) and TextArea where the user can write his notes (attached a picture). The user using a virtual keyboard (touch) to enter any characters.
I am using the append method to append the next Char to the TextInputControl class (both Combo and TextArea Inherit from it). When I try to deletePreviousChar() in the TextArea it works, but in ComboBox it fails
I put some System.out.println() to see what is the problem and it seems that with the ComboBox the class is loosing the Caret position after every action
Here is my code: (Look it also as a attached picture)
public void changed(ObservableValue<? extends String> observable,
String oldVal, String newVal) {
if (newVal != null) {
if (lastNodeInFocus instanceof TextArea) {
switch (newVal) {
[Code] ....
Here is the Debug results: CB = Combo TA = TextArea B=Before A=After , the numbers are the caret position (also attached as a picture )
CB - append B 0
CB - append A :1
CB - append B 0
CB - append A :2
CB - append B 0

JSP / JSTL :: How To Display Dynamic ComboBox
Feb 6, 2013we had a requirement to display a combobox which is filled with some values on the webpage when somebody checks the checkbox which is present on the webpage.
The approach we have taken is ajax. how we did this is, when somebody checks the checkbox on the webpage we are initiating the ajax call requesting a servlet. this servlet pulls the data from the database, places the data in the request and forwards the request to a jsp. In that jsp i am writing simple html combobox and populating the values in the combobox from the request using JSTL and this jsp will be sent as response to ajax call. The ajax gets the html as responce which contains a combobox and i am just placing that html ( the complete response) in a div which is next to checkbox.
In this approach there is lot of pain. if i have to display 10 html components dynamically based on some condition then i have to have 10 jsp's one for each component. I always feel this is a wrong way of doing things. what is the best approach to deal with the dynamic stuff on webpages.
Prevent ComboBox From Being Used - Getting Null Pointer Exception
Oct 8, 2014Should the piece of code below set prevent the comboBox from being used? All it does at the minute return a null pointer exception. See I am using the same window but I have an if statement so if a condition is true then it will change certain aspects of the window. I want it to be true if it equals export which is does and it's populated fine but when I try and hide it if the condition equals import it returns a null pointer?

JSF :: Enabling And Disabling ComboBox / TextBox Based On Actions
Apr 24, 2014This is my modalPanel code:
<rich:modalPanel id="createManagedObject" moveable="false" autosized="true" width="500" rendered="true" domElementAttachment="form">
<f:facet name="header">
<h:panelGroup>
<h:outputText value="Create Managed Object"></h:outputText>
</h:panelGroup>
</f:facet>
<f:facet name="controls">
<h:outputLink onclick="#{rich:component('createManagedObject')}.hide(); return false;">
[Code] ....
As shown in the above code:
I have following components in ModalPanel:
1) ComboBox
2) Instance
3) Save and Cancel
I wanted some validation here :
For example:
- The Instance Text box and SAVE button should be disabled. When the pop up appears.
- The Instance Text BOX gets enabled only when any selection happenes in COMBO Box
- The SAVE button gets enabled only when COMBO BOX and INSTANCE TEXT BOX is filled.
- Let the CANCEL button be enabled always.
JavaFX 2.0 :: Sizing Width Of ComboBox Based On Items
Apr 16, 2015I have a ComboBox -- just a simple ComboBox with string items.
My string items aren't very long (5 letters max), but the ComboBox shows quite wide relative to my strings. So I would like to size my ComboBox to the size of my strings.
I messed around with setting the CellFactory of the ComboBox, and have the Cells produced by the CellFactory set the preferred width of the cells to some constant like 100. That worked in terms of changing the size of the ComboBox to the preferred width of 100.
But what I really want to do is to compute the preferred width from the string items. For that I need to be able to compute how wide a string item will be when rendered. And I guess that depends on the font size used by the ComboBox to render strings, which probably depends on the platform (OS X different to Windows?).
