JavaFX 2.0 :: Replacing SplashScreen With Preloader Stage - Flickering?
Aug 29, 2014
I'm trying to set up a splash screen where a native splash screen is shown initially and then replaced with the stage from my preloader. This is fairly simple to do. I use the below code to get everything lined up properly.
private void alignStage(Stage stage) {
SplashScreen splashScreen = SplashScreen.getSplashScreen();
if (splashScreen != null) {
// Align the stage based on the current splash location
Rectangle bounds = splashScreen.getBounds();
stage.setX(bounds.getX());
stage.setY(bounds.getY());
[Code] ....
The problem I'm having is that my Stage isn't actually shown by the time the commented event gets fired. The API for onShown says:
Called just after the Window is shown.
My guess is the window has transitioned to being shown, but there's a slight delay until it gets rendered on screen. If that's a decent assumption, is there a reliable way I can make sure my preloader stage is visible on screen before I hide the native splash?
The best option I can think of so far is to delay hiding the native splash until the preloader gets the BEFORE_START notification. This works (no flicker), but, since both splash screens are actually visible for a while, using a transparent splash doesn't work very well (which actually isn't too big of a deal).

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) ?

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 ...

When reading RT-38432 I see that Danno mentions the possibility to use:
com.sun.javafx.application.LauncherImpl.launchApplication(YourMainClass.class, Preloader.class, args);
I've never used the javafx-packager and have always used the above instead. However, I assumed I was missing out on some optimization related to example 9-5 and example 9-6 of Deploying JavaFX Applications: Preloaders | JavaFX 2 Tutorials and Documentation. I always assumed the supported packaging:
1) Loads only the JARs / resources needed to launch the Preloader.
2) Launches the Preloader.
3) Loads all other application JARs / resources.
4) Launches the application.
Now I'm thinking that's only the case for Web Start deployments. For standalone deployments is it the same as a normal Java application where all of the application JARs are included as part of the classpath?

After some attempts I seen that my preloader is not shown using native package (Windows and Mac).
Running the jar that is run from the file.exe instead I can see the splash screen.
This is the relevant part of my build.xml
<fx:application id="fxApplication" name="app" version="3.0" mainClass="it.app.Main" preloaderclass="it.app.preloader.SplashScreenUi" toolkit="fx" />
As said, running the jar file instead of exe file the splash screen is displayed.
I printed some logs into splash screen class: when I run the app from the jar this logs are printed, instead when I run the app from .exe file these logs are not present.

I am looking for a way to find a resize animation for an application I'm developing. I found this answer but I figure there could be a better method out there,
Java - How do I create a Resize animation for JavaFX stage? - Stack Overflow
I am just looking to select something in a list, then press a button which would enable the animation and enlarge the stage. This will happen twice.

I want to create a slot machine in NetBeans, with JavaFX library (without using JavaFX Scene Builder) but i have some problems to create UI.
I created algorithm already but without visuals.
Now my code is:
public class BEST extends Application {
private ImageView var; //init imageview of images
public static void main(String[] args) {
launch(args);
[Code] ....
createbottom(); and creategr(); i wrote already (and my program creates grid pane of random images with double dimension array, random and imageview) and program runs, but i don t know how to keep track of credits balance,in the same time to create new random gridpane of images and to get rid of every gridpane.
Here is creategr();
private GridPane creategr(){
final GridPane creategr = new GridPane();
int[][] newarray=new int[3][3];
int w=100;
for(int i=0; i<3; i++){
for(int j=0; j<3;j++)
[Code] ....
Button "SPIN" is created in createbottom();.

I noticed that all my stages can be resized to zero size regardless of their contained scene, which is very ugly. How do I keep them from doing that? Is there some sort of intelligent way to bind the stage's min size to the size of the scene so that no part of the scene is cut off?

I need to create a program that draws a graph, but for now, all I have done is two lines: the X and Y axis. The program is designed in a way as to automatically resize the graph when the window is resized.
Is this code in some way extremely inefficient? I get TERRIBLE flickering when I resize the window. Is there something that will at least reduce the flickering?
mainApp.java:
import java.awt.*;
import javax.swing.*;
public class mainApp {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setSize(300,300);
frame.setVisible(true);
[Code] ....
I have added a screenshot that shows the window flickering.

I am trying to call another swing frame from my current frame. And after calling second frame i dispose the current frame.
But while second frame coming on the screen, current frame gets dispose and second frame takes some seconds to appear on screen.
So its creating a bad flickering effect on screen and its not suitable for my application.
I want that first frame will call sencond frame and it will not look like second frame is called. I just want to cancel flickering effect.
Here is my source code.
1st Frame:
public class Welcome extends JFrame {
JFrame f;
JTextArea nameField,nameField1;
JLabel lable;

Image image = ImageIO.read(this.getClass().getResource("body1.jpg"));
Image image1 = ImageIO.read(this.getClass().getResource("body.jpg"));
Image headr = ImageIO.read(this.getClass().getResource("headr.jpg"));

I have been stuck on this now for almost a week, the problem is that the textfield keeps flickering. I have read that swing does not work well with fullscreen exclusive mode, but I'm not sure what else to do other than create my own class similar to a textfield and detect every single key press which doesn't seem the right thing to do.
- If this line is uncommented "TextFieldTest.this.tfChatField.paint(g);" then it will display the textfield at the top of the screen, and a flickering textfield at the bottom(which is where it's meant to be)
Java Code:
package textfieldtest;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.DisplayMode;
import java.awt.Graphics;
import java.awt.Graphics2D;
[Code] ....

Is that the only way to code the JOptionPane? Seems rather similar to Sys.out
--- Update ---
I had more than this, but post was deleted somehow and this was the gist of it:
for(i = 0 ; i < charArray.length; i++){
if(Character.isDigit(charArray(i))){
address.replace("6", "*");
address.replace("7", "*");
Is there a better way to scan a character array for digits and replace any number in the array with another character ("*") in this case? The array is the address, " 1234 Runner Road " .

how to replace the values in my array with the results of my function factorial.
public static void main(String[] args) {
//this is my main function:
int[] array = {5,4,3,2,1};
int i = 0;
System.out.print("results: ");
for (i = 0; i < array.length; i++){
System.out.print(factorial(array[i]));
[code]....
So, what I'm trying to do is change the contents of the array "array" into their factorial value. So, they should be replaced with {120,24,6,2,1}. then add those using linear sum but that's a different story.

so my task is to write a code which would ask user to input the year as integer and first three letters of the month with first being an upper case letter. Than the program would determine the number of days for given year and month.
Currently I have a brain crash on how to check, if the user has provided the month with first character being upper Case. If not, than the program would automatically correct the character. Problem starts at line 17.
import java.util.Scanner;
public class DaysOfMonth4_17 {
public static void main (String[] args) {
//Initiate scanner
Scanner input = new Scanner (System.in);
//Ask for year input and use is as INT
System.out.println("Enter the year");

I'm currently trying to build a DAO based application where you use a text file as a data source. It have worked out well until I tried to delete lines from the file.
public void delete(DTOBil dtobil) {
try{
reader = Files.newBufferedReader(Paths.get("databilar.txt"),charset);
writer = Files.newBufferedWriter(Paths.get("temp.txt"), charset, StandardOpenOption.CREATE_NEW);
String line = null;
while((line = reader.readLine()) != null){
[Code] ....
I've managed to fill out the temp file with everything except the line I wanted to remove, but when I try to replace the original file with the temp file it won't work. It casts the error: "temp.txt -> databilar.txt".
I've also tried to use the renameTo method without any success...

I have a file which contains certain positions ([a][b]) that require to be placed in a certain multi-dimensional array. For example I might have an array String[][] that is a size of 6x6 but only have values in positions [2][1] and [3][2]. Because it is important for me to maintain the given array size and also do certain actions with the given positions I cannot modify the size. In addition I need to count the surrounding neighbors each element has (including elements that are null). However because some of my further code cant process with null elements I need to remove all null elements with " " (blank).
I am not sure how this is done or if it's even possible. If it is not possible how can I do something as close as possible to my needs?

With the code below, I am trying to replace all regex matches for visa cards within a given text file.
My first test was with a text "new3.txt" exclusively containing the visa test card 4111111111111111. My objective was to replace the card with "xxxx-xxxx-xxxx-xxxx". This was successful.
However, when modifying the text file to include other characters and text before and after (ex: " qwerty 4111111111111111 adsf zxcv"), it gives mixed results. Although it successfully validates the match, it replaces the whole text in the file, rather than replacing solely the match.
When trying this search and replace with words (rather than a regex match), it does not have this behavior. What am I missing?
import java.io.*;
import java.util.regex.*;
public class BTest
{
//VISA Test
private final static String PATTERN = "(?s).*4[0-9]{12}(?:[0-9]{3})?.*";
public static void main(String args[])
{
try

How can I replace each letter for example "abcde" to "edcba" with StringBuilder only and without the reverse tool. This is what I tried:
StringBuilder str=new StringBuilder("abcde");
int indexBegin=0;
int indexEnd=4;
for(int i=0;i<str.length();i++){
str.setCharAt(i, str.charAt(indexEnd));
indexEnd--;
}
System.out.println(str);
The output is:edcde with i understand why its wrong ,the last two letters already swap so it didnt take from the original str.

I have 2 strings
String value ="/abc_12_1/abc234/abc/filename.txt";
String src="abc"
Sring tgt=xyz
Now I have to replace the string in variable value in case of exact match; I am trying to do the following :
if(value.contains(src)
{
value.replaceall(src,tgt);
}
Now the problem here is it replaces all the occurrence of abc in the string value and I get the below output as :
value=""/xyz_12_1/xyz234/xyz/filename.txt";
However my requirement is only in the case the value exactly matches with source the replacement shd happen. I am expecting the output like this :
String value ="/abc_12_1/abc234/xyz/filename.txt";
Also the above code is in a function which will be called multiple times and the values will keep on changing. However the target and source will remain the same always.
