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 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.

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;
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 ....
I have developed JavaFx application with playback option using JavaFx Media player and slider controls. I am updating slider value using javafx mediaplayer.currentTime().addListener() method by adding Change/Invalidate listener.
While playing MP4 video, slider values are not updating (Change/Invalidate listener not getting triggered while playing video) on Mac OS(version : 10.9.1). Below is the sample code snippet.
Like the title says: I'm loading a local HTML file in a WebView which contains Javascript. The script works without any problem when the page is first loaded, but when I reload it or load another local page, Javascript simply stops working silently for no apparent reason and with no error or exception of any kind.
I am developing an application to share my client screen with server, it is working well on swing. But i want to develop as web application, i am trying to using applet. But i am facing the fallowing problem..,
1) The Applet screen also open and project also running well on server mechine. But unable to see the client screen on the server.
2) The problem may be to display the JDesktopPane or JInternalFrame.
My working Server Code extends withe JFrame..Java Code:
I want to add a text as a first value of the combobox.I tried with cobSections.insertItemAt("Click here to select a link please", 0); in the code
pPaint.setLayout(pPaintLayout); { cobSections = new JComboBox(); cobSections.setRenderer(new MapSectionItemRenderer());
[code]...
but it didn't appear. Still the first entered value appears when the program is run.should I put this line on some other place, or is there any other code, other way to add this text as first value in the combobox?
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.
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class NameAge extends JFrame { //Create text fields and labels private final JTextField firstName = new JTextField(15);
I 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?

I make a coding a subject system for my internship project, I use JComboBox to choose name of faculty. I want to call selected item of faculty from another class to choose subject under the selected faculty.
How can I call selected item from another class?
This is my coding for select faculty.
public class lectInterface(){ private void saveDataActionPerformed(java.awt.event.ActionEvent evt) { String staff_id=staffID.getText(); int staff_Id=Integer.parseInt(staff_id); String Name=staffName.getText();
[Code] ....
and below is coding for another class
try{ LectInterface lI = new LectInterface(); String host = "jdbc:derby://localhost:1527/STUDLECDB"; String uName = "studlecdb"; String uPass = "studlecdb"; Connection con = DriverManager.getConnection( host, uName, uPass );
