JavaFX 2.0 :: How To Properly Customize Text Label Of ComboBox
Jun 8, 2014
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 try to bind the text-property of a selected cell of a TreeView to a label. So if the user click on a cell in the treeview the label should show the cell text. Now I am quite confused about the options I got to do so. Should I use label.textProperty().bind( ... ??? ... ) The treeview.onMouseClicked()property? or something different?

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 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
[Code] ....

Have have just started working with JavaFX and SceneBuilder having been a long time Swing developer.
My first foray into the world of JavaFX involves building a rather simple desktop application to parse text based log files with regular expressions.
Currently I am working on the main window for this application. I built a scene in SceneBuilder using a BorderPane for my root.
I placed a TitledPane which contains a TableView in the center section of the BorderPane and a VBox which contains several Buttons in the right section of the BorderPane. When I view the layout in SceneBuilder using the Preview menu item to show the preview in a Window, SceneBuilder shows the scene laid out exactly as it is in the work are and as I would like it laid out.
When I close SceneBuilder and go back to my IDE (Eclipse) and build and run the application the scene is displayed in a window differently than in SceneBuilder preview. When the application executes the scene is laid out as if there has been something placed in the top section of the BorderPane, the TitledPane containing the TableView is centered in the window and the VBox containing the buttons are not aligned with the top of the TitledPane containing the TableView because it is as if there is a "null control" in the top section of the BorderPane.
Why is there a difference in the way SceneBuilder displays the scene and the way the executed application displays the scene?
Also, I recently made some changes to the layout of the controls in SceneBuilder (e.g. changed some padding and location of some controls in their containers and again the scene looks perfect in SceneBuilder but when I execute the application now some components in the container where I made the changes are truncated when the scene is displayed when the application executes.
It is almost as if SceneBuilder is interpreting the FXML one way and the JavaFX API during run time is interpreting the FXML another way.

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?).

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 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 ....

I was trying to do a short program that scans a text for a given word and then tells you how many times that word was repeated in the text. The result was this:
var text = prompt("Write the text to be searched through");
var word = prompt("Write the word to be looked for. Beware of capitals!");
var hits = [];
for (var i = 0; i < text.length; i++) {
if (text[i] === word[0]) {
[Code] ....
However, this doesn't scan the text properly. I think the problem lies in one of the lines from 4 to 8, but, even after thinking quite a lot, I couldn't understand what was it. I thought that by saying that the letter of the text in position [i + k] shuold be equal to the letter of the word in position [k] I could make it work, but it doesn't.

why this code doesnt work? Its suppose to be a simple frame with a button that puts text to the frame when u click it. The problem is actionPerformed method, when it tries to call the stuff inside the constructor it all goes wrong. I switched the method body with a system.out.println() and it all works fine.
import java.java.awt.Label;
import java.awt.Button
import java.awt.BorderLayout;
import java.event.*;

I want to set an html text on al label, but also call a method.
I tried:
Java Code:
scoreMens.setText("<html>joejoe<BR>jaja<BR</html>" + naamSpeler.laatKaartenZien()); mh_sh_highlight_all('java');
But the naamSpeler.laatKaartenZien(), which returns a string, doesn't show on the label. Is there a way to call a method and use a html text on a label?

I am developing a java swing application. In which i want to set a different text to a label in same program ( in single JFrame). I dont want to use another JFrame instead i want to use setText method of java and set different text to a label at different intervals of time according to my need.
I am using java 1.7 sdk and pupy linux as OS. Below i am giving source code.
What i am doing is in constructor of class i am setting an image to JFrame and setting text "Welcom...". And when user clicks on this JFrame a method is called which will clear the text "Welcome.." and sets new text to another label "Enter...." and from there another method is called and it clears label "Enter..." and sets a text "Plzz wait..". and yet there are more methods, i havnt provided here.
But what is happening is it shows welcome text and then directly Plzz wait..
Its not showing text Enter... because control is finished after last method gets executed.
My concern is i want to show all the setText (my messages) in a sequence. Without using another JFrame. There is no any user input other than user will click on first welcome page.
public class BackgroundFrame extends javax.swing.JFrame {
JLabel setTitle1;
JLabel setTitle2;
JLabel setTitle3;
JLabel setTitle4;

I'm doing a software Java GUI - JFrame form like this:
1. The user wants to click on a button that opens a bunch of images that will be displayed as thumbnail in the bottom of the JFrame .
2. Then the user wants to select/click one of the thumbnail and make appear the corresponding image in it's original size on above(center) of the JFrame.
For doing this I used 3 JPanel.
One contains a JButton that opens the jfilechoser dialog window,
the second "panelPreview" is for putting the thumbnails created,
and the third "panelGrande" is for the image in it's original size.
The firs part "1." is ok.
But in the second part : I got one error when I want to put the ImageIcon in to the JLabel with the further intent of displaying it.
lblBig(imgIcoVett[i]);
In this project I'm dealing with arrays of ImageIcons and JLabels, so it's a bit advanced level for me, so I'm not sure that I wrote right the part of the MouseListener too.
The error displayed by netbeans says "cannot find symbol symbol: method lbl (ImageIcon) local variables referenced from an inner class must be final or effectively final"
Here I attach the project I did with netbeans"AAAD Unlayout 2.zip", but if you just need the highlight of the code, here it is too:
private javax.swing.JButton btnOpenfile;
private javax.swing.JFileChooser jFileChooser1;
private javax.swing.JPanel jPanel1;
private javax.swing.JLabel lblBig;
private javax.swing.JPanel panelGrande;
private javax.swing.JPanel panelPreview;
