JavaFX 2.0 :: Progress Indicator In ListView Has Border And White Background?
Dec 1, 2014
If I "embed" a ProgressIndicator inside a ListView it has an ugly border and a white background. It looks like there's a TextField below the ProgressIndicator.
Why does it behave like that and how to solve it so that the progress indicator is transparent.

import javafx.collections.FXCollections;

import javafx.scene.control.ListCell;
import javafx.scene.control.ListView;
import javafx.scene.control.ProgressIndicator;

Since the upgrade to JavaFX 8u20 my ProgressIndicator won't rotate anymore when using Caspian style. Is there any workaround for this?

public class TestApp2 extends Application {
public static void main(String[] args) {

I have a selection listener attached to a TreeView as shown below
treeView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<TreeItem<Pair<VideoSourceType, String>>>() {
@Override
public void changed(ObservableValue<? extends TreeItem<Pair<VideoSourceType, String>>> observable, final TreeItem<Pair<VideoSourceType, String>> oldValue, final TreeItem<Pair<VideoSourceType, String>> newValue) {
// do something
treeView.getSelectionModel().clearSelection();
}
};
What I want to do is to "do something" and then clear the selection so that it can be selected again. However, I cannot re-select the same item from the TreeView until I first select a different item.

I want to synchronize a List<String> with the selected items of a ListView. In the real project, I want to synchronize the selected items of a TreeView and the selected images of a galery (custom control).
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.collections.FXCollections;
[Code] ....
In most cases, the program works as expected but sometimes there are some issues.
- For example, when I launch the application and select all the items with Ctrl-A, the event { [One, Two, Three] added at 0, } is fired so the list of strings contains incorrectly 4 elements [One, Two, Three, One].
- Another example, when selecting all the items (with Shift+End), two events are fired { [One] removed at 0, } and { [One, Two, Three] added at 0, }, that's correct. But when I remove the last element with Shift-Up, 3 events are fired { [Two] removed at 1, }, { [Three] removed at 2, } and { [Two] added at 1, } and an exception is thrown:
java.lang.IndexOutOfBoundsException: toIndex = 3
at java.util.ArrayList.subListRangeCheck(ArrayList.java:1004)
at java.util.ArrayList.subList(ArrayList.java:996)
at com.sun.javafx.binding.ContentBinding$ListContentBinding.onChanged(ContentBinding.java:111)

I'm trying to add filtering content in ListView by selected date from DatePicker. Every position(movie) has it's emission date saved, so when you choose date that you're interested in, it will show just matching titles. I was trying to use this solution:
@FXML
private void initialize() {
titleList.setCellFactory((list) -> {
return new ListCell<Movie>() {
@Override
protected void updateItem(Movie item, boolean empty) {
super.updateItem(item, empty);
[Code] ....
But when I add new position and change date, that I'm filtering by, every title disapear and don't reload. How can I make this work with every change?

I have an app that was working with JavaFX 2 on JDK 7 but seems to no longer work in JavaFX 8 on JDK 8. The story is that I have a ListView where I have provided my own CellFactory. Within the class that extends ListCell, in the updateItem() method, I create an HBox that contains some text and a new button.
I register an onAction() callback for the button. The end result should be a list with entries which contain buttons and when a button is clicked, the onAction() callback is invoked. However, when I run it and click the button, the callback is NOT being fired. This exact code was working on JavaFX 2 and JDK 7.

I only want the context menu to be showen if the user is clicking on an actual listview item, not if they click anywhere else in the listview. I know this is possible and I found answers to similar problems, but in the end they didn't provide enough infomation for me to solve my issue. I found this example on how to do it with a list view containing String objects, but what if my list view contains another object, in my case a wrapper class? I have a wrapper class to keep track of the key, but I only display the value variable in the listview, through calling the toString method. So the cells still contain a wrapper.
class Wrapper(int key, String value) {
..
}
public String getValue() { return value; }
public SimpleStringProperty getValueAsProperty() { return new SimpleStringProperty(value); }
public String toString() { return value; }
[Code]....
But line 05 gives me a NullPointerException, why? I do this after I've set the items of the list view by doing listView.setItems(..).

I am using:
Java:..... 1.8.0_20JavaFX:... 8.0.20-b26
I have this class:
public class Person {
private SimpleStringProperty name;
public SimpleStringProperty nameProperty(){
if(this.name==null){
this.name=new SimpleStringProperty();
[Code] .....
I have this:
lista = FXCollections.<Person>observableArrayList();
lista.addAll(new Person("uno"),new Person("due"),new Person("tre"));
myListView.setItems(lista);
The problem is if I add /remove an item all is fine, the listView refreshes correctly:
Person p = new Person(tfld_textAdd.getText());
lista.add(0, p);
But if I change a value on an item into the observable list it doesn't:
lista.get(0).setName("new value");
I also have a table linked in the same way and the table workd correctly after I updated my Java version...

In my Java SWT application, I have few methods, that take longer time to complete. These methods has to be initiate and run as response to button click. There I want to implement progress bar to show the progress/status of long run method. Long run methods are Java Processes, in which it executes some command line functionality. (ex: run ls method in Linux).
Process p = Runtime.getRuntime.exec(command)
In progress bar status is set using setSelection method which takes int as argument. How to indicate the progress of process in progress bar, because I don't have int value to pass into setSelection method of progressbar.

I need to work with multiple threads in background in a JavaFX application. I have a screen with ten buttons and I need to 'bind' each thread with the button that started the thread. If the user pressed a button that had started a thread (in the main screen, MainController.java), I need to recover it to display the information that contains to display it on the controls of Details Screen ( a second screen, DetailController.java).
What Class do you recommend for this? Service?
[URL] ....
It is possible to name the threads with any of these classes?

I have a TextArea and want to set a linear-gradient as background, which works fine:
.text-area {
-fx-background-color: linear-gradient(to bottom, red 0%, blue 100%);
}
The problem is that if the TextArea contains much text (and long scrollbars) it is nearly only red. Only if you scroll down to the bottom, it becomes blue.
I want the red-blue gradient always look the same, no matter how much text there is.
In HTML there's something like background-attachment: fixed, which would do the trick, but not so in JavaFX.
Can I achieve it nonetheless. Preferably without any ugly workarounds, like a transparent TextArea within another Pane where the wrapping Pane has the gradient.

I am developing a number of Data Structures in Bluej. Iv created a nice little arraylist program, and want to add a password generator to this program. People are already prestored within the arraylist, and contain attributes such as ID, name, password, etc. I can search a persons name within the list and then view their ID, password, and encrypted password. I want to add a field which will show password strength, bare in mind the password is already stored within the program and will not be entered via the user.
I understand that this could be done via a regular expression, or using some count method where certain goals/sets of characters increase the count which determine strength.

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 would like to have a touchable listview and two image buttons underneath.
Eclipse allows me to do this but I suspect the touchable listview won't work.
public class MainActivity extends ListActivity implements OnClickListener {
.....
But I can't use
insClick.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
.......
}
});
Because the IDE does not like setOnClickListener, OnClickListener and onClick. How to allow a combination of listview and image buttons..

What I am doing is loading a new image from resources in my project, so that I can get the size. Using this, I create a new BufferedImage with those dimensions. The following code is what I am using to take the original BufferedImage, and scale it.
Java Code:
public ImageIcon getBackImage(){
before = new BufferedImage((int)img.getWidth(null), (int)img.getHeight(null), BufferedImage.TYPE_INT_ARGB);
int w = before.getWidth();
int h = before.getHeight();
try{
URL url = getClass().getResource("/Blue_Back.png");
before = ImageIO.read(url);
[Code] ......
The scaling seems to be working fine, but what I have noticed is a line of approximately 10 pixels at the top of the image. I took the original image and blew it up to ensure that I wasn't just enlarging undesired portions and this wasn't the case. I then tried to fetch a subImage of the BufferedImage, and that also left the padding at the top. Is there something I am missing that is placing this undesired padding at the top of my bufferedImages ?
