I have a multi scene JavaFX FXML application [URL] ....
I have added a TextField to Scene2.fxml and Scene3.fxml files each scene has its own Controller Class with a ScreensController class that loads a HashMap with Id name, Node screen that is defined in the ScreensFramework
class (Main class)
public void addScreen(String name, Node screen) {screens.put(name, screen);}
So each time you click a Button on a screen (scene) you fire an ActionEvent and move to another screen
What I would like to do if it is possible is use the value in the TextField on Sceen2 and transfer it to the TextField on Scene3. I have discovered that unless both FXML files are loaded this is so far not possible. This is a desktop application. So how do you create a variable that is GLOBAL and has a life after one class is unloaded or one FXML file is unloaded?
At this point I do not want a database to accomplish this task.I have developed in Visual Basic 6 where I would just declare a global variable that could be used through out the application.
Lets say I have a desire to convert and entered value to Centigrade or Fahrenheit and that I have two Radio Buttons to designate the type of conversion with the Answer posted to a TextField on Scene Two from a button click event on Scene One ok Now I would like to convert the value in the TextField on Scene Two to Kelvin and reflect the value on Scene Three in a TextField by clicking a button on Scene Two
lets say I have 4 FXML files sceneONE sceneTWO and scenMain and I created 4 controllers ControllerONE and MasterController
So far I can navigate to the different scens with just the MasterController code below...
BUT because I have two FXML files I can not capture the value in the first FXML file and pass it to the second scene
This project is my attempt to adapt the FXML style code from this web site
Switching to Different Screens in JavaFX and FXML | JavaFXTutorials
Which uses this code to switch scenes
//get reference to the button's stage stage=(Stage) btnS1.getScene().getWindow(); //load up OTHER FXML document root = FXMLLoader.load(getClass().getResource("ATTwo.fxml"));
But will not permit variable transfer due to scope of variables which reside in two different FXML files
public class MasterController implements Initializable{@FXML public Button btnS1; @FXML public Button btnS2; @FXML public Label lblS1; @FXML public Label lblS2; @FXML public TextField txfS1; @FXML public TextField txfS2; @FXML public AnchorPane root;
I'm making a tic tac toe program. Currently I have a welcome screen for my tic tac toe game, once the button is clicked I want the main game to open. I have created two FXML VBox windows created from JavaFX Scene Builder. I want to know how to close the welcome menu and launch the 2nd FXML window.
This 2nd FXML window will have it's own controller where the tic tac toe calculations will be held.
Here is the event listener on when the mouse action is performed on the button
The stacked bar chart not working with FXML and controller class. My code is given below
Controller class /* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package javafxapplication27; import java.net.URL; import java.util.Arrays; import java.util.ResourceBundle; import javafx.collections.FXCollections; import javafx.collections.ObservableList;
[Code]...
When I run this program, only the barchart populating, Stacked bar chart not displas any graph.
We are currently doing the bi directional property binding in the java code, but it would be nice to declare those bindings at the point where the UI Controls are created, ie in our FXML files.
I understand bi-directional binding of the form
value="#{controller.path.propertyName}" was removed from JavaFX 2.1
I used the SceneBuilder to create an applications and it works quite well. Now I got a problem to set the pref. size of a ScrollPane to the size of the app.
I want to install a binding between the scroll pane's pref. size and the stage's pref. size. Since the scroll pane field reside in the FXMLController class I need a way to access this field.
I'm new in JavaFX world. I'm going to write an application using FXML and this application will use embedded database. Is there any tutorial or example showing how to connect FXML (using controller as I expect) with database. I'm using Hibernate with classic JAva - is it possible to work with Hibernate with JavaFX?
I have created an application in SceneBuilder, and want to call a pop up (also created separately in scene builder) when a certain button is pressed. How?
I have an FXML table view. And I want to assign value from an tableview create on class to FXML tableview. But at the end is not displaying data.
Example:
@FXML private TableView fxmlTable; private TableView insideClassTable; public class SomeClass { public SomeClass(){ insideClassTable = new TableView(); ////////////////////////////////////////////////// Filling insideClassTable with data. ////////////////////////////////////////////////// fxmlTable= insideClassTable; } // some other code and main }
If I set value to fxmlTable, data are display correctly, but if assign value to insideClassTable first and then make fxmlTable=insideClassTable they are not display.
Label is not a valid type., TableView is not a valid Type., etcera
This exception I then solve with placing an import tag inside the .fxml file.
However as I do not know each import name, I have to look this up like writing down:
Label label = new Label();
inside a class and then place my cursor on it to see which import name Eclipse generates.
This import name i then put inside the .fxml file with <? import ?> beginning and end tags with question marks around it.
Is there anyways to automatically generate these import tags inside an .fxml file even if you don't know the import name for the control you want to use?
I have a TextArea that I am trying to restrict user inputs to allow only IP addresses format in that Area. So I thought of only allowing digits and decimal points. For multiple IPs, One IP per line, the TextArea needs to accept new lines. For the most part what I have below is working except for delete. I can't delete any entry even if I am using the associate Unicode. Is this even the correct way of doing it?
public class RestrictIpInputTextArea extends TextArea { @Override public void replaceText(int i, int il, String string){ if(string.matches("[0-9_u000A_u232B_u0008_u2421_._u007F_u005F]") || string.isEmpty()){ super.replaceText(il, il, string);
[Code] .....
In my FXML File I calling it as <RestrictIpInputTextArea ......
I am trying to figure out the best way to load localized versions of FXML content. I know that I can localize strings, images etc. by specifying a ResourceBundle when loading the FXML using FXMLLoader with a ResourceBundle. But what about if you need to tweak the FXML for different locales (eg, adding more real estate for certain elements, different fonts, etc). Is there any way to create localized versions of FXML content? The only thing I can come up with is a naming convention like MyForm.fxml, MyForm_de_DE.fxml, ... and trying to load them based on the locale, but I'd have to come up with my own fallback for specific locales that aren't found.
I need to create dynamic Layouts that are created from java source code, using JAXB. As FXML does not have a schema, this gets me in trouble.
Scene Builder cannot be used for dynamic Layouts, but if there really is no schema I could use, maybe someone knows how Scene Builder generates the fxml files.
while (key != 3) { if (key == 2) { System.out.println("Input from a file"); // System.out.print("Enter file name: "); // String str = expression.nextLine(); int i = 0; File file = new File(

What I need to happen is the file gets read in, the file is in the form:
a * ( b + c ) / 2 + ( 8 * b ) a = 5 b = 10 c = 20 ( x + y ) * z x = 13 y = 21 z = 3
And so on. My code is supposed to start at the beginning and have output like:
Infix: a * b ( b + c ) / 2 + ( 8 * b ) variable values: a = 5 b = 10 c = 20
**It then needs to store the variable names along with their values in a hash table**
postfix: a b c + * 2 / 8 b * + value: 155
And it continues reading the file in the same fashion.
My issue is I am not properly extracting the variables and their values from the file. I have the variables in an array list actually, so I have those, but don't know how to efficiently navigate to the values, then store the character and value in a hash table, while protecting against possible blank lines within the file. Thus just calling nextLine()s and next()s wouldn't work to get to values because they would lead to an error.
Now that I have figured out how to return a single variable from a method I am on to the next step, I need to return 2 or 3 variables from a method. I have searched the internet on how to do this to no avail (am I doing the wrong search? I do not know) but what I need to do is return a second (and eventually a third variable)
Here is what I have
private static String Engine() { String engine = ""; int enginePrice = 0; System.out.println("Choose a engine size:"); System.out.println("[4] cylinder");
I need to download multiple files from my jsp,My jsp will receive a string array,and in that each array will have a filePath.I ggot the solution to download multiple files by Using ZipOutPutStream,But i don't want to Zip Them,I need to download them in a folder.In that folder i should have all the files.
<c:set var="streamValue" value="${streamValue}"/> <%! void addFile( ZipOutputStream outZip, File f, String name ) { FileInputStream in = null ; try { // Add ZIP entry to output stream. outZip.putNextEntry( new ZipEntry( name ) ) ;
The problem is what to do when the source file for a class gets too big ( a judgment call for sure). Is it possible for one class to be defined in multiple files and if so how do you do it, and is it good practice?
I do see ways to refactor into a base class or move code into a helper class but sometimes the abstraction is cleaner as a single class that does a lot of stuff. My problem is how to organize a BIG class?
I am downloading around 50 PDF files programmatically using Java program(like a servlet service) one after another in for loop. I am observing that , i'm getting timeout error after few files are downloaded itself. How to solve this problem and download more files programmatically using java? The files are in my server at different location.
I'm going through a file (MySQL dump) and I wish to take the SQL and create individual files for each table (as opposed to what I do now, which is just run through the whole thing).
Now, this all works fine - but what I want to do is create a separate .sql file for each table.
However, I can't figure out the best way to do this - how do I create a new FileWriter (or instance of whatever class is required) as I'm going through the while loop? That or pointing the same one to different files as I go through the loop.
It can be assumed that the file may exceed RAM - I want to do it line by line rather than slurping the entire file as a string and "cheating" that way.
There appear to be many (a bewildering amount of) I/O options and I'm just unsure.
I am trying to compile multiple jar files into one jar file from inside a java program. I know how to do this with shell scripts but I would rather have a universal application than one that will only run on Mac, Windows, or Linux. This is my current compiler code:
if(System.getProperty() == "Mac OS X"){ Runtime.getRuntime().exec("javac -classpath jar1.jar; jar2.jar"); }
I would then continue this on for Linux and Windows, but this limits my application.
I am using itext to create pdf files , i have filtered some records (preferably i can say around 90) which has the option to open pdf for individual record. Now I need to open all the pdf's of filtered records on a single click , without asking for a open dialogue box. How to go about this ??
