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

import javafx.stage.Stage;
public class TestApp2 extends Application {
public static void main(String[] args) {

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.

I wish to display a progress bar during a lengthy file translation process. When I created a ProgressBar class to do this and tested it with a short test program, it seemed to work fine. But when I add my ProgressBar class to a package containing various other classes, put that package in a jar file, and then execute the class using the progress bar from a menu in my main program, the frame of the progress bar shows up with the appropriate caption but the JLabel, JProgressBar, and JButton are not displayed. I have gone over my code numerous times and checked that the ProgressBar class constructor is getting the proper arguments.
// package gov.nasa.jpl.ephemeris;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
/**
* Progress bar with message text above the bar and a Cancel button below it
*/
public class ProgressBar extends JFrame {
private boolean _cancelled = false;
private JProgressBar _progressBar = null;
[Code] ....
I have also been wondering whether I need a separate instance of the border for each panel, or whether I can just create one instance and use it for all three panels.
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 built my application under Windows XP (x32), Eclipse Luna (x32), JDK 1.8 (x32 - beta version B116).
When i launch it, the splashscreen (preloader) appears !
I rebuilt my application under Windows 7 (x64), Eclipse Luna x64, JDK 1.8.0_20 (x64).
When i launch it, the splashscreen doesn't appear !!!
For information, The structure of my application :
app
| libs
| preloader.jar
myapplication.jar
runtime
The behavior of JDK 1.8.0_20 about the management of the preloading mecanism is it different of the behavior of JDK 1.8 (B116) ?
In the documentation of StackPane i read: "The stackpane will attempt to resize each child to fill its content area. If the child could not be sized to fill the stackpane (either because it was not resizable or its max size prevented it) then it will be aligned within the area using the alignment property, which defaults to Pos.CENTER."
But as I add another Pane (Anchor- or BorderPane) this added Pane is shows always in left upper corner of the StackPane. How could I force my StackPane to center another AnchorPane?
I have a stylesheet (mystylesheet.css) with following entry:
.flowpane{
-fx-background-color: rgb(0,0,0);
}
In then start-method of my application I execute:
StackPane root = new FlowPane();
Scene scene = new Scene(root,primaryScreenBounds.getWidth(),primaryScreenBounds.getHeight());
scene.getStylesheets().add(css.getFile());
root.applyCss();
No FlowPane gets black. But if I do that in SceneBuilder and add the stylesheet to root than after loading Fxml-file the FlowPane gets black.
Another approach:
StackPane root = new FlowPane();
Scene scene = new Scene(root,primaryScreenBounds.getWidth(),primaryScreenBounds.getHeight());
scene.getStylesheets().add(css.getFile());
root.getStyleSheets().add(css.getFile());
root.applyCss();
Nothing happens.
StackPane root = new FlowPane();
Scene scene = new Scene(root,primaryScreenBounds.getWidth(),primaryScreenBounds.getHeight());
scene.getStylesheets().add(css.getFile());
root.getStyleSheets().add(css.getFile());
root.getStyleClass().add("flowpanel");
root.applyCss();
Doesn't work too;
but root.setStyle("-fx-background-color: rgb(0,0,0) works. But I need to style my application by css-files.
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 {

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...
I'm using Scene Builder 2.0 and have added an ImageView to the parent AnchorPane. I've added my PNG files for the app icon and the various buttons. I select the ImageView in Scene Builder and then crawl the filesystem to the project package folder and select the PNG for the Image. The assigned image is displayed in the Imageview in Scene Builder in both design mode and Preview mode.
While everything else shows up properly when the app is executed, the image assigned to the ImageView does not display.
From the FXML file:
<ImageView fx:id="ivBRULogo" fitHeight="64.0" fitWidth="64.0" layoutX="14.0" layoutY="14.0" pickOnBounds="true" preserveRatio="true" AnchorPane.leftAnchor="14.0" AnchorPane.topAnchor="14.0">
<image>
<Image url="@BRU_PE_B_64.png" />
</image>
</ImageView>
What might be occurring between the compiled app and what Scene Builder generates?
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.
I have a list of Tabs which are dynamic depending on how many cars are in a database. If there are 10 cars there will be 10 tabs called car 1, car 2, car 3, etc. Each tab simply displays a photo and details of the car.
I have a JMenuItem that says start SlideShow and end SlideShow
What i would like to do is automatically slide through tabs when the start Slideshow is clicked.
Is there any way to Rotate jPanel in java (without using Paint Function).

I need my Java program (I'm working in Eclipse if it matters) to detect if an image is a portrait or a landscape, but since i am directly downloading them from my camera they only have it written somewhere in metadata, the image width and height is the same for landscape and portrait. I have the rotation code and the rest of the program working, but I need to somehow get a variable (for example integer one) to tell me if it is a portrait or a landscape image. I tried getting to the metadata but my Eclipse decided that import com.drew.metadata.Metadata; cannot be resolved.
BufferedImage image = ImageIO.read(new File(imagePath, imageName)); and after I get the variable "orientation" it looks like this

}
I'm trying to replicate the rol(rotate left) instruction in assembly though can only get as far as shifting the bits with '<<' or doing Long.rotateLeft(var, 5). Both of these method don't wrap around the bits as the rol instruction does.

I'm trying to get a progress bar to work on my GUI.
This is what I have so far, the parameters are taken from another class that takes in an image in packets from a Raspberry Pi and stores them to a file on PC.
public void ImageInfoReceivedHandler(int sizeOfFile) {
progressBar.setMinimum(0);
progressBar.setMaximum(sizeOfFile);
progressBar.setIndeterminate(false);
[Code] .....
The println are printing out the correct values and they are being implemented in the methods, but nothing is happening in the GUI.
I have a thread setup in the GUI when a button is pressed
getImageButton.setText("Timer Started");
transmit = new transferImage(port);
lblImgProcess.setText("Getting Image, Please Wait");
transferThread = new Thread(transmit);
transferThread.start();
So the thread starts and image is then transmitted, does the progress bar need to be in that event handler?

How would I get the overall progress of reading the directory I give to it, for example, if I give it the root directory of my computer, it would read through ALL my files and folders, and that works fine.But how would I get progress for a progress bar?
I thought that simply constructing a progressmonitor would show the dialog, and wrote the following code.
[Code] ....
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.beans.*;
import java.util.Random;

But apparently i was wrong and all i get is an empty JFrame and no Dialog. I even added my own subclass of SwingWorker in case a SwingWorker had to be created in order for a progress monitor to exist. How can I make it show?

I have a datagrid in which i have to display progress bar with the task completed in %.
For example i have two fields in a table source count and completion count.
Where source count in 100000 rows and 50000 rows have been inserted.
In another table and status is displayed in the table.
So I need to display in a progress bar that 50% task has been completed.
