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 have created a text file that contains a small list of toy names and prices, like:
Barbie, 12.95 Lego, 15.99 Hot Wheels, 5.00 Power Rangers, 6.49
And what I would like is my application to read the contents of the file and store the toy names in a list component. And then I want to be able to select a toy name from the list and add it to a shopping cart that is a list component as well. I want to the application to have menu items and buttons to allow me to remove items from the shopping cart, clear the shopping cart of all selections, and check out.
When I check out, the application should calculate and display the subtotal of all the toy names in the shopping cart, the sales tax (which can just be 8 percent of the subtotal), and the total.
How to create this simple application example I've just made up, and I'm going to add and use this example to create a bigger application myself.

I create and populate someLinkedList with '*' characters as soon as a gameLinkedList object is created, so my class is something like
private int size; public class gameLinkedList{ private CharNode game; public gameLinkedList(String someWord){ size=someWord.length(); for(int i=0;i<size;i++){CharNode aNode = new CharNode('p');
I am learning Java on my own and I am taking on very small project by myself for fun, and I'm just stuck on this small part of the project. So I have created a text file that contains a small list of toy names and prices, like:

I am using the Javafx 8 Date Picker. Its works fine. I have defined a stylesheet for my application and in that style sheet i have a style for Button. I apply this style to the every scene. Now my question is: When I use the datepicker and I click on the calendar icon, the datepicker popup appears and the left and right arrows adjacent to month and year fields in the seems to pick the style of the button class from style sheet defined in my application., Is there a way to avert this and tell datepicker to use default styles and not the styles defined my application.
I tried removing the style at runtime from the scene, but of no use.
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.
The problem is from "perspective" in -webkit-transform. Without it's ok. But with this one, the result is different from a standard browser like chrome or safari.
I have a JPanel that's using a simple GridBagLayout.
JPanel panel = new JPanel(); GridBagLayout qPanelLayout = new GridBagLayout(); qPanelLayout.columnWidths = new int[] { 0 }; qPanelLayout.rowHeights = new int[] { 0 }; qPanelLayout.columnWeights = new double[] { Double.MIN_VALUE }; qPanelLayout.rowWeights = new double[] { 0.0 }; panel.setLayout(qPanelLayout); componentCount = 0;
Based on user input I am adding sub-panels to the panel. These sub-panels may vary in height. They take up the full width of the Panel.
public void add(Component comp) { GridBagConstraints gbc = new GridBagConstraints(); gbc.fill = GridBagConstraints.HORIZONTAL; gbc.insets = new Insets(2,2,2,2); gbc.gridx = 0; gbc.gridy = componentCount++; panel.add(comp, gbc_questionPane1); }
The odd behaviour I'm seeing is that if the height of the new sub-panel I'm adding is less than the height of the largest sub-panel currently displayed then the main panel does not repaint. If its height is equal or greater then the Panel does repaint, and any sub-panels that were added but not visible before are now painted. What have I missed?
I would like to avoid "Not on FX application thread" exceptions beforehand. Is there a reliable way to determine if Toolkit.checkFxUserThread is called by a specific method call? Such a check could then be included in the build process.
I'm currently learning about Swing but I can't get my head round this piece of the code. Here is a simplified gui (not interested in the gui part but the execution)
public class SwingDemo implements ActionListener { SwingDemo(){ JFrame jfrm = new JFrame("Simple gui pro"); //rest of code public static void main(String[] args) { new SwingDemo(); }
I get the above, create a new instance of SwingDemo in the main thread which starts up the gui through the constructor. However, then the tutorial says that I should avoid doing the above but do this instead:
public class SwingDemo implements ActionListener { SwingDemo(){ JFrame jfrm = new JFrame("Simple gui pro"); //rest of code public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { //why do this instead? public void run(){ new SwingDemo(); } }); } }
Reading, it talks about an event-dispatching thread which has completely lost me... Why not just instantiate the object directly instead of creating another thread?
im having an issue with the 3rd thread that are supposed to merge the two sorted sub arrays , i pass the 2 subarrays to my runnable function sortlist and they are renamed IntSortList 1 and 2 and th1.start() and th1.join() are called and it works fine, but then i have another runnable constructor that takes IntSortList 1 and 2 but it does take a runnable. below is the code in my main,
Runnable InSortlist1 = new sortList(data2p1); Runnable InSortlist1 = new sortList(data2p1); Thread th1 = new Thread (IntSortlist1); Thread th2 = new Thread (IntSortlist2); try { th1.start(); th1.join();
Release 8u40 introduces the TextFormatter concept in the text input field area. It is currently a new property of the TextInputControl class. This is definitely a more elegant way to deal with validation than overriding "replaceText(...)".
Shouldn't this property also be available in list, table and tree cells? Are there plans to do this (before we make our own implementation) ?
I would like to create list of entities which is populated by a search function with the data coming from our REST webservice. However I would like it to be multi-line, with the first line being details from the entity itself and the second line buttons for options that can be performed.
So as an example say my entity is People, the first line would contain columns for first name, last name, gender, DOB, etc. The second line would be buttons for "Edit Person", "Print Person details". With the standard TableView I can't see anyway to alternate between one row of data and another row of buttons.
What is the best way to synchronize a Model representing a complex UI composite w/ a FlowPane's backing list?
Currently I have a change listener on the Model. Upon an add I create a new UI composite and manually add it to the FlowPane's backing list via flowPane.getChildren().add(). Similarly if there is a remove, I iterate over the FlowPane's children, grab the right Node, and remove it. Similarly, if there is a modification detected, I iterate over the FlowPane's children, grab the right Node, remove it, recreate the UI composite, and re-add it to the list. I also need the list to be sorted, so I implemented a UIComposite comparator and call FXCollections.sort() on the FlowPane's backing list. I feel like that is hacky, but it works. It would be cool if I could maintain sort order in my model somehow and have that automatically propogated to the FlowPane's list.
I am correct in assuming that there is no way to have a complex binding in between an ObservableList<CompositeViewModel> and the FlowPane's backing list (ObservableList<T>)?
Some kind of translator that could create a new UIComposite whenever there is a new CompositeViewModel added to the Model list.
I've been looking through the Java API for a component similar to the direction selector compass in google earth (the one that acts like a circular scroll bar) to no avail. Any existing component before breaking down to creating the component myself.
In a java application project called mycomposites, i created xhtml with a composite component interface and implementation in mycomposites/ src/ main/resources/testcomponents/myComponent.xhtml...Then I created a new project testmycomposites added mycomposites as dependency. Here is the source of an xhtml that should use myComponent:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"
[code]...
However running project, I get error:<tp:myComponent> Tag Library supports namespace: http://java.sun.com/jsf/composite/testcomponents, but no tag was defined for name: myComponent
If i put the same custom component in resources/testcomponents folder of the same project everything works fine.I can't find any example in wich custom composite components are located in a dependency.
