JavaFX 2.0 :: Adobe Flex To Java Bridge
Feb 1, 2015
Recently I've decided to reimplement the existing utility tool, that is written on Flex, in Java language, but I have faced a problem which is as follows. This tool is utilizing a compiled .swc library which is used to perform some calculations. The point is that my new Java-based tool has to output same values as the Flex-based one, but it doesn't. My attempts to recreate the the functionality provided by swc library has lead to nothing. The only way I see, that will ensure that new values are same as old ones is to, somehow, call the swc functionality from my Java code.

I would like to know the J2EE architectural explanation with respect to HTML5 and Adobe Flex technologies. It is just like knowing over all J2EE architectural aspects and how HTML5 and Adobe Flex technologies are used to satisfy those aspects in order act as client side components.

I am using netbeans scenebuilder and I am a little confused on how I would convert my state capitals java code to a javaFX app.
public class StateCapitals {
Scanner in;
public static void main(String[] args) {
readData();
}
public static void readData() { // Location of file to read
File file = new File("statecapitals.txt");
[code]....

What would be the most effective method to display data grabbed from a web source that is queried every second, for example the most recent EUR/USD price?
I already have access to the data stream, and I've built a simple FXML in javaFX that contains a grid; I'm not sure how to approach putting the live ticking data into the grid so it continues to update as the price changes, for example.

I was doing a project in a usual Java Application, but now maybe I have to use some tools that are contained in javafx.scene.media.MediaPlayer so I wonder if can it all work? Will javafx methods and such works?
I have to use javafx.scene.media.MediaPlayer beacuse I have to create a very simple audio player (one jbutton and one jcombobox).

I know that oracle has released a statement saying that JavaFX will eventually replace Swing. What is the advantage of JavaFX? The new format, using "stage" instead of JFrame, seemed weird. Why is this change necessary? What benefit do we reap from JavaFX that Swing does not have?

I've been on this for a while and for some reason I just can't seem to get this to work. I know my code is solid, but it won't display my image. I've tried swithcing the image to different directories and also using different image sizes and types. I even used Orcale's guide to display your image, but still no go! All I get is a blank canvas? There are no errors. I'm also running NetbeansIDE 8 that supports JavaFX and I made sure the project is a JavaFX Application project.
All I get is a blank new window, but no images.
Here's my code:
package javafxapplication3;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.image.Image;
[code]....
The homework called for me to display it three times - the first one regular, second resized, and the last one rotated. I even deleted the extra images in hope at least one appears.

I'm working on a project right now in JavaFX, and got stuck. I am drawing a path consisting of CubicCurveTo's and I wonder if there's any way to get the X and Y coordinates from certain parts of that path.
Imagine following a curve (path) with a pencil slowly, and every second you take note the X and Y coordinate. I mean I'm not interested in the control points or start and end points, but the points "in between", preferably at a certain interval.
I've searched for many things online, but have trouble knowing exactly which words to search for. "Paths" often bring up file paths, traversing, coordinates etc. all fail to give me any good results.
I tried to be as specific I could, and I don't think my current code is of any interest in this matter.
(The point of it all is that the path should simulate the path a person walks, and I will store the coordinates in a database for every second).

When i press a button, i want to create a new object in my window(that i have created using scenbuilder, so i have a FXML file and a Controller class). In the window where i have a create button, there are also some textfields where you are supposed to enter name and date.
What i want to do is take the input from the TextField and store is temporally in a String variable, Its this strings i want to take the data from when i create a new object on my View. When i try to do something with the TextFields i get multiple errors that i dont understand at all.
I know my code may be very un-structured the absolute right way, i know, but i dont have time reconstructing and trying to understanding new patterns .The object is the circle and the vertical line.

public class TimelineController{
StageClass sc = new StageClass();
NewTimelineController nt = new NewTimelineController();

I have noticed that you can style JavaFX controls using their sub-structure.
E.g. to style the label in a table column header to be left justified I can do this :
.table-view .column-header-background .label { -fx-alignment: center-left ; }
How can I style my own nodes/controls doing this? Basically it amounts to asking how the selectors like ".column-header-background" are associated with sub-structures of my Java control/node objects. So suppose I have something like
.fancy-node .fred .label { ... }
How does JavaFX associate fancy-node and fred with something in my implementation of a Node/Control?

ToString()-Representation of KeyEvents. I was expecting '$' as text value, because Shift was pressed.
Unfortunately, KeyTyped is not fired in this case, so I am not able to get the information from this event.
How can I get the actually typed '$' from KeyPressed?
KeyEvent [source = BorderPane[id=cnt_borderPane], target = Button@1a3fc21a[styleClass=button]'', eventType = KEY_PRESSED, consumed = false, character = , text = , code = SHIFT, shiftDown]
KeyEvent [source = BorderPane[id=cnt_borderPane], target = Button@1a3fc21a[styleClass=button]'', eventType = KEY_PRESSED, consumed = false, character = , text = 4, code = DIGIT4, shiftDown]
KeyEvent [source = BorderPane[id=cnt_borderPane], target = Button@1a3fc21a[styleClass=button]'', eventType = KEY_RELEASED, consumed = false, character = , text = , code = SHIFT]
KeyEvent [source = BorderPane[id=cnt_borderPane], target = Button@1a3fc21a[styleClass=button]'', eventType = KEY_RELEASED, consumed = false, character = , text = 4, code = DIGIT4]

I'd like the GUI to be drawn based on definition file. Is it possible to "generate" fxml (like PHP does html) so I could do this:
for (...) {
command_to_generate (<button ....>);
}
?
Or is using legaxy javaFX code the only way to achieve it?

My JavaFX code like this:
WritableImage image = scene.snapshot(null);
File outputFile = new File("C:PSBJavaFXApplication1src est0.jpg");
ImageIO.write(SwingFXUtils.fromFXImage(image, null), "jpg", outputFile);
When open this jpg, its background is in orange color. For png type, it works great.

I am new to JavaFX and OpenCV. The Problem is, that JavaFX can't handle Mat objects. First I load an image as a BufferedImage. Then i have to convert this to Mat. Do my image Processing with OpenCV and again convert the result image to a BufferedImage to display in on my UI. Here are the methods for converting Buff to Mat and Mat to Buff I found on the internet:
public static Mat img2Mat(BufferedImage image)
{
byte[] data = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();
Mat mat = new Mat(image.getHeight(), image.getWidth(), CvType.CV_8UC3);
mat.put(0, 0, data);
return mat;
[Code] ....
Next I do some OpenCV stuff:
public static BufferedImage hello(BufferedImage img) {
Mat source = img2Mat(img); //Convert Buff to Mat
BufferedImage outImg = null;
try{
System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
[Code] ....
Finally I call the hello method in my controller:
void menuItemTestFired(ActionEvent event) {
try {
result = ImageProc.hallo(bImage);//bImage is an image I've loaded before.
imageView.setImage(SwingFXUtils.toFXImage(result, null));
[Code] .....
Unfortunately I get a lot of errors. Here are the first one:
Caused by: java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat(III)J
at org.opencv.core.Mat.n_Mat(Native Method)
at org.opencv.core.Mat.<init>(Mat.java:471)
[Code] ....
Can't figure out why this doesn't work. -.-

I using this code to fir FlowPane into ScrollPane
FlowPane flowPane = new FlowPane(Orientation.HORIZONTAL);
ScrollPane scroll = new ScrollPane();
scroll.setContent(flowPane);
scroll.viewportBoundsProperty().addListener(new ChangeListener<Bounds>() {
@Override
public void changed(ObservableValue<? extends Bounds> ov, Bounds oldBounds, Bounds bounds) {
flowPane.setPrefWidth(bounds.getWidth());
flowPane.setPrefHeight(bounds.getHeight());
}
});
Unfortunately this maybe is not the best solution. Is there another more simple way to fit FlowPane into ScrollPane in Java 8?

I'm using WebView to display an OpenLayers3 map, e.g. Animation example from openlayers.org. When I lock my screen and unlock it, none of the openlayers layers are re-drawn. Sometimes bringing the window in to focus or a small resize of the component will cause the map to go blank. This doesn't occur in any browser I've tested, so it seems to be a WebView specific issue, although it also seems to be layer specific and possibly cache related. I've only tested on Windows, 1.7.0_51 x64 and 1.8.0_05 x64 ....

There are a few things lacking in the TableView's keyboard navigation handlers. In tracing the code, the behavior is handled via TableViewBehavior and its super classes. If I want to augment that behavior, how do I do it?
Ideally, I would like to subclass TableViewBehavior, but I don't see how I can do it. This gets created in the TableViewSkin ctor:
public TableViewSkin(final TableView<T> tableView) {
super(tableView, new TableViewBehavior<T>(tableView));
...
}
but as you can see there is no factory method to create the behavior class. If there was, I could subclass TableViewSkin and override the factory method.

At the end I just copy and paste the code from section 9.3.4 (the long startup task example) and it still won't work. After starting the application I only see some black screen flickering at the upper left screen and then the main app shows up.
What I have done:
Using Netbeans 8.0 under Linux(Fedora20 64bit), JDK 1.8u5 ...
Here are the two classes - the main app :
import javafx.application.Application;
import javafx.application.Platform;
import javafx.application.Preloader.ProgressNotification;
[Code]....
On my machine I see only a little black flickering on the left upper screen and then immediately the app is shown...
The only way I can get this to run is to set the custom preloader property in the Netbeans-project properties. If you use a maven based project in Netbeans you did not got this option ...

I'm trying to play an encrypted HLS video using MediaView and MediaPlayer is throwing a "can't create player" exception. Searching for a solution all I found was this post from january last year, saying it is not supported and to add a feature request. I looked in the JDK bug system for HLS/live streaming and didn't saw anything related. Is this still not working on the latest JavaFX?
