I would like to change the default skin of JavaFXapplication during runtime. How I can do this using ComboBox? Now I use this code to change the value:
setUserAgentStylesheet(STYLESHEET_MODENA);
Is there a way to change the skin in a run time?

I 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.

In the below example i'm trying to add a combo box inside a subscene. But it is not working correctly .If I select a value from the combo box ,it's is not set in the combobox and the combobox values are not displaying properly.

I 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

I 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?).
Switching from Swing to JFX 8, I am trying to find out how to do something I would normally do in a super-simple ListCellRenderer, i.e. customize the String displayed for an item. I tried this:
ComboBox<Integer> combo = new ComboBox<>();
combo.getItems().addAll(1, 2, 3);
combo.setCellFactory(new Callback<ListView<Integer>, ListCell<Integer>>() {
@Override
public ListCell<Integer> call(ListView<Integer> param) {
[Code] .....
However, when I do this, the customized String is not used for the selected Item (rather the standard toString() value of the item). Apart from that it is no longer selectable using the mouse (I submitted a bug report for this at [URL] .... but that is not really the point of my question.
Anything else I have to do to make sure the selected item is also rendered using the custom cell or is there a different mechanism for this?
I have noticed a strange behavior of Combobox element. The number of visible rows is not the same established by setVisibleRowCount() method. It happens when changing the items list dynamically. The following example reproduces it. I think it is Javafx 8 bug. I have tried unsuccessfully to trigger some event indirectly to refresh the combobox drop down.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ComboBox;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class TestComboBox extends Application {
private int count;
[Code] .....
I did an implementation which is an extension of javafx.scene.control.ComboBox
Inside I imported the Class ComboBoxListViewSkin
import com.sun.javafx.scene.control.skin.ComboBoxListViewSkin;
I think this might be the reason as this comboBox is not recognized at the import to the scene builder library. I can show up the import dialog of custom controls, but my custom ComboBox is not showing up. All other implementations are there correctly as they are loaded from my customControl.jar file
I use the ComboBoxListViewSkin for the functionality to scroll to an item in the combo as a user types a letter on the keyboard.
I do this by:
/**
* This method scrolls the itemView of the items to the first item starting
* with the given char or string
*
* @param pressedKey
*/
public void scrollToChar(String pressedKey) {
String value = pressedKey.toUpperCase();
for (Object userEntry : getItems()) {
[Code] ....
I really need to show up my custom Combo in the scenebuilder, as otherwise the rest of my fxml is not editable in sceneBuilder 2.0 ....
How can I set the default stylesheet for a user control that I have created? I want to make the control available for anyone to use and I want it to use a stylesheet by default without the user of the control having to do anything. I also want it to be possible for the user of the control to override the definitions set on the default stylesheet if he wants to.

I'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 ());

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.

I've got 2 view classes with their own viewcontroller. In view 1 i'v got a combo box with a observablelist wicht show me some values.
What i want is to put an new value to the combobox through the controller of view2.
When i make the observablelist static it works but i think that isn't a nice way.
we 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.
