JavaFX 2.0 :: Buttons In ListView Not Firing OnAction
Jun 2, 2014
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 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..

I have a ListView with ListCells that are complicated things containing other nodes. I want to turn of ListView selection behavior (so not allow selections) without turning of events to the ListCell nodes in the ListView.

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 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(..).

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.Scene;
import javafx.scene.control.ListCell;

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...

Is there a possibility to use events for additional mouse buttons, like the next or previous mouse buttons, in javafx? If I use the setOnMousePressed event on a node, it only throws an event for the "PRIMARY" "SECONDARY" and "MIDDLE" buttons.
node.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override public void handle(MouseEvent mouseEvent) {
System.err.println("mouse button: " + mouseEvent.getButton());
}
});
If I use this java application [URL] .... it is also possible to throw events for the next or previous mouse buttons of the mouse. But not in my javafx application.

I have a Dialog with no buttons (the dialog pane contains some graphic elements which act as my buttons). I show the dialog and try to click the close window button on the dialogs title bar, and the dialog does not close! I read the docs and it appears that only dialogs that have one or more buttons can be abnormally closed (and only under certain well defined sensible conditions). How can I abnormally close a dialog with no buttons?

I am writing a program that solves sudoku puzzles. It has a Swing GUI with a "solve" button. I have written an actionListener class with an actionPerformed method that is invoked when the user presses this button. It is the following:
public void actionPerformed(ActionEvent event) {
try {
worker = new SudokuSolveWorker();
worker.addPropertyChangeListener(this);
worker.execute();
SolveFrame sf = new SolveFrame();
} catch (Exception exc) {
System.out.println(exc.getMessage());
exc.printStackTrace();
}
}
The code creates a worker, a new instance of SudokuSolveWorker. The worker.execute() statement causes the doInBackground() method of this class to be called. This solves the Sudoku. A property change listener "picks up" the result:
public void propertyChange(PropertyChangeEvent event) {
try {
System.out.println("" + javax.swing.SwingUtilities.isEventDispatchThread());
SudokuModel solvedModel = (SudokuModel) worker.get();
} catch (Exception exc) {
System.out.println(exc.getMessage());
exc.printStackTrace();
}
}
As I wrote, this works without freezing up the user interface in the sense that the program seems unstable. However, the user interface does not respond to "commands" (mouse clicks) anymore until the worker thread has finished.
In the first code fragment I create an instance of SolveFrame which is an extension of a JFrame. It is a simple frame with a "cancel" button. It is drawn on the screen, even though it is called after the worker.execute() statement. I'd like the user to be able to click this "cancel" button, after which the solving of the sudoku puzzle should be stopped. However, since the program does not respond to mouse clicks anymore, the "cancel" button cannot be pressed.

I am learning out design patterns and doing a little fun project on Model Control View (MCV). I got the concept down, it is pretty simple for the most part. However my buttons are not working.
Here is the code:
public class Controller
{
private Model model;
private View view;
Controller(Model model, View view) {
this.model = model;
this.view = view;
[code]....
It runs but nothing. My other questions is how can I make a box that will print the results.

Right now, i'm trying to do is when a user clicks on my GUI button, it would display a text of information on the button they selected. I'm using an arraylist of objects and i'm trying to input the function inside the mouse click function. But I'm not sure how to properly display that information. Here is my GUI code. I'm working on the raven button. I have animal interface, with a parent class of Bird, and child class of Raven. How I could display this correctly...
public class AnimalJF extends JFrame {
private JPanel contentPane;
private JTextArea textArea = new JTextArea();
/**
* Launch the application.
*/
public static ArrayList<Bird> Birdlist = new ArrayList<Bird>();
public static void main(String[] args) {
Birdlist.add(new Eagle());

So I have a Jframe that has a set of functions that act on a node. What I want to do is allow the user to expand the gui by creating new sets (copies) of these functions when they have more nodes.I thought of hiding extra sets and making it appear they are adding them by making them visible.
