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'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
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 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.
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.
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;
Scanner in = new Scanner(System.in); ArrayList<rand> selectedRand = new ArrayList<Rand>(); selectedRand.add(new Rand(in.nextLine()));
I have created the most minimal code for creating an array list. I was wondering what the basic syntax of accessing objects methods that are within an Array List. So if I was to trying and get a method such as [.returnValue,] how would this look within a Rand object that is declared in a Array List Since you cannot simply declare a new Rand object and say:
newRandObject.returnValue();
And you must go through the actual slotted portion of the array list. I have searched the web and my text book for an example however none are provided.
I have a situation where I have 2 classes and an array of objects which are causing me trouble.
The object type is one I have created - it is made from a class which is neither of the 2 classes I previously mentioned.
The array is created and occupied in Class1 and the problem arises when I try to reference one of the element from Class2.
At first I forgot the the array would be local to Class1.main so I made the array a global variable using:
Java Code: public MyObjectType[] myArray; mh_sh_highlight_all('java'); Then I tried accessing an element (2) from Class2 using:
Java Code: Class1.myArray[2] mh_sh_highlight_all('java'); However I get errors saying that I can't access the static variable from a non-static context.
I understand a little bit about static and non-static objects/methods but don't know how to fix this. Do I need to include "static" in the array declaration?
public class BookExamples { String title; String genre; public static void main(String[] args) { // TODO Auto-generated method stub System.out.println("Hey");
[code]...
Eclipse gives me an error for b1.genre = "hey"; saying "Syntax error on token "genre", VariableDeclaratorId expected after this token". I am learning from a HeadFirst Java book that is all in Java 5.0 version which may be part of the problem.
I'm not new to java but i'm not able to solve the following issue: I have a class
public class Localizzazioni implements java.io.Serializable { private <complexType> id; public getId()....... public setId().....
The complexType is a class defined in the code somewhere. Now I want to access it in another class I have
Set localizzazioni = new HashSet(0); localizzazioni=opere.getOiLocalizzazioneOperas(); -- this object give an object of tyoe HashSet for(Object object : localizzazioni) { object.get......... // i cannot use any method defined in the class Localizzazioni }
Why I cannot write inside the for object.getId() and using it?? In other word how i can access the element contained in the object?? the object is an iterator of type Localizzazioni . The class Localizzazioni has some method but i cannot use them? why ....
I've tried a couple ways to do it, and they don't work. I'm aiming for functionality like I got with the regular for loop, but from an enhanced for loop. Is this simply beyond the scope of an enhanced for loop, or am I just not getting the right syntax?
TestObject to1 = new TestObject("first", 11); TestObject to2 = new TestObject("second", 12); TestObject to3 = new TestObject("third", 13); TestObject to4 = new TestObject("fourth", 14); TestObject to5 = new TestObject(); List<TestObject> testList; testList = new ArrayList<TestObject>();
[code]....
The TestObject class is simply an int and a String, with getters getInt and getString. It all works fine with the regular for loop.
edit: I should probably mention that I know what I have in the enhanced for loop now will only display the class name and the hash. I've tried adding the .getString and .getInt, and tried a few other ways to make it work. I just reverted to this because it compiles and runs
I want to know is there any way we can call parent class method using child class object without using super keyword in class B in the following program like we can do in c++ by using scoop resolution operator
class A{ public void hello(){ System.out.println("hello"); } } class B extends A{ public void hello(){ //super.hello(); System.out.println("hello1");
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.
TimelineMainView Controller public class TimelineController{ StageClass sc = new StageClass(); NewTimelineController nt = new NewTimelineController();
I hope I'm putting this question in the right folder. I have an array of objects, and I have defined a setter for a variable in the object. When I call the setter, I get a NullPointerException. Here is the relevant code for the object.
public class Digit extends Thread { private int digit; public void setDigit(int digit) { this.digit = digit; } // run method follows }
Here is the portion of the main class where I define an array and then call the setter.
Digit[] digits = new Digit[10]; for (int i = 0; i < digits.length; i++) { digits[i].setDigit(i); // NullPointerException occurs here }
I am creating a simple ArrayList program that would enable one to input their username to it using a scanner. However, i am getting this error: "Exception in thread "main" java.lang.NullPointerException
at home.Members.addUser(Members.java:16) at home.Main.main(Main.java:14)"
Here is the code! :
Main.java class Java Code: import java.util.Scanner; public class Main {
