Touchable Listview And Buttons

Jul 25, 2014

I would like to have a touchable listview and two image buttons underneath.

Eclipse allows me to do this but I suspect the touchable listview won't work.

public class MainActivity extends ListActivity implements OnClickListener {
.....

But I can't use

insClick.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
.......
}
});

Because the IDE does not like setOnClickListener, OnClickListener and onClick. How to allow a combination of listview and image buttons..

JavaFX 2.0 :: Buttons In ListView Not Firing OnAction

Jun 2, 2014

I have an app that was working with JavaFX 2 on JDK 7 but seems to no longer work in JavaFX 8 on JDK 8.  The story is that I have a ListView where I have provided my own CellFactory.  Within the class that extends ListCell, in the updateItem() method, I create an HBox that contains some text and a new button. 

I register an onAction() callback for the button.  The end result should be a list with entries which contain buttons and when a button is clicked, the onAction() callback is invoked.  However, when I run it and click the button, the callback is NOT being fired.  This exact code was working on JavaFX 2 and JDK 7.

JavaFX 2.0 :: Re-selecting Item From ListView

May 14, 2014

I have a selection listener attached to a TreeView as shown below
 
treeView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<TreeItem<Pair<VideoSourceType, String>>>() {
   @Override
   public void changed(ObservableValue<? extends TreeItem<Pair<VideoSourceType, String>>> observable, final TreeItem<Pair<VideoSourceType, String>> oldValue, final TreeItem<Pair<VideoSourceType, String>> newValue) {
        // do something
       treeView.getSelectionModel().clearSelection();
   }
};
 
What I want to do is to "do something" and then clear the selection so that it can be selected again. However, I cannot re-select the same item from the TreeView until I first select a different item.

JavaFX 2.0 :: Binding ListView Selected Items

Oct 19, 2014

I want to synchronize a List<String> with the selected items of a ListView. In the real project, I want to synchronize the selected items of a TreeView and the selected images of a galery (custom control).
 
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.collections.FXCollections;

[Code] ....
 
In most cases, the program works as expected but sometimes there are some issues.
 
- For example, when I launch the application and select all the items with Ctrl-A, the event { [One, Two, Three] added at 0,  } is fired so the list of strings contains incorrectly 4 elements [One, Two, Three, One].
 
- Another example, when selecting all the items (with Shift+End), two events are fired { [One] removed at 0,  } and { [One, Two, Three] added at 0,  }, that's correct. But when I remove the last element with Shift-Up, 3 events are fired  { [Two] removed at 1,  },  { [Three] removed at 2,  } and { [Two] added at 1,  } and an exception is thrown:

java.lang.IndexOutOfBoundsException: toIndex = 3
    at java.util.ArrayList.subListRangeCheck(ArrayList.java:1004)
    at java.util.ArrayList.subList(ArrayList.java:996)
    at com.sun.javafx.binding.ContentBinding$ListContentBinding.onChanged(ContentBinding.java:111)

JavaFX 2.0 :: Filtering ListView By Selected Date

Apr 20, 2015

I'm trying to add filtering content in ListView by selected date from DatePicker. Every position(movie) has it's emission date saved, so when you choose date that you're interested in, it will show just matching titles. I was trying to use this solution:

@FXML
  private void initialize() {
  titleList.setCellFactory((list) -> {
  return new ListCell<Movie>() {
  @Override
  protected void updateItem(Movie item, boolean empty) {
  super.updateItem(item, empty);

[Code] ....
 
But when I add new position and change date, that I'm filtering by, every title disapear and don't reload. How can I make this work with every change?

JavaFX 2.0 :: How To Not Show ListView ContextMenu When Right Clicking On Null

Jun 16, 2015

I only want the context menu to be showen if the user is clicking on an actual listview item, not if they click anywhere else in the listview. I know this is possible and I found answers to similar problems, but in the end they didn't provide enough infomation for me to solve my issue. I found this example on how to do it with a list view containing String objects, but what if my list view contains another object, in my case a wrapper class? I have a wrapper class to keep track of the key, but I only display the value variable in the listview, through calling the toString method. So the cells still contain a wrapper.

class Wrapper(int key, String value) {
..
}
public String getValue() { return value; }
public SimpleStringProperty getValueAsProperty() { return new SimpleStringProperty(value); }
public String toString() { return value; }

[Code]....

But line 05 gives me a NullPointerException, why? I do this after I've set the items of the list view by doing listView.setItems(..).

JavaFX 2.0 :: Progress Indicator In ListView Has Border And White Background?

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.

JavaFX 2.0 :: Modifying Item In Observable List Doesn't Update ListView

Oct 3, 2014

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...

MCV - Buttons Not Working?

I am learning out design patterns and doing a little fun project on Model Control View (MCV). I got the concept down, it is pretty simple for the most part. However my buttons are not working.

Here is the code:

this.model = model;
this.view = view;

It runs but nothing. My other questions is how can I make a box that will print the results.

Using GUI With Buttons And ArrayList

Sep 18, 2014

Right now, i'm trying to do is when a user clicks on my GUI button, it would display a text of information on the button they selected. I'm using an arraylist of objects and i'm trying to input the function inside the mouse click function. But I'm not sure how to properly display that information. Here is my GUI code. I'm working on the raven button. I have animal interface, with a parent class of Bird, and child class of Raven. How I could display this correctly...

public class AnimalJF extends JFrame {
private JPanel contentPane;
private JTextArea textArea = new JTextArea();
/**
* Launch the application.
*/
public static ArrayList<Bird> Birdlist = new ArrayList<Bird>();
public static void main(String[] args) {
Birdlist.add(new Eagle());

Getting The Index Of A Matrix Of Buttons

Dec 7, 2014

I am attempting to get the x and y coordinate of a matrix of buttons. I have googled my way to failure and read the docs and I think I am traveling of track.

Below is where I create a matrix of buttons via Swing

public class View extends Mybuttons{
 private static final long serialVersionUID = 1L;
JFrame frame;
JPanel matrixPanel, optionsPanel;
Mybuttons[][] matrixBtn;

Later in this class:

JPanel matrixPan(){
matrixBtn = new Mybuttons[25][25];
JPanel panel = new JPanel();
panel.setSize(550,550);
panel.setLayout(new GridLayout(25,25));
//creating a 25x25 matrix of buttons

[Code]...

In the controller class I am trying to get the index of each button in the getUnvisitedChildNode method. I need to do this so I can search the buttons around the button passed to it and check if they are been visited yet. Below getUnvisitedChildNode you will be bfs (breadth first search).

private Mybuttons getUnvisitedChildNode(Mybuttons b){
//example of some of the things I have tried
int x= Mybuttons.getComponentAt(b);
int y= Mybuttons.indexOf(b);
int j=0;
return b;
}

Order Buttons In A JPanel

Sep 22, 2014

I'm learning the swing options of Java, and my first exercise was the typical Chat Room. I got everything right: TextField, TextArea, the jpanel at left side and the buttons inside of it. BUT I can't order the 2 buttons (1 north, 1 south). I've already looked for answers, but didn't find anything and I tried to asked the teacher, but she was too lazy to look for the error. Here is my code:

f=new JFrame("Chat Room");
b1=new JButton("Send");
b2=new JButton("Emoticons");
public void showWindow(){
p1=new JPanel();
f.getContentPane().add(p1,BorderLayout.EAST);
p1.add(b1,BorderLayout.NORTH);
p1.add(b2,BorderLayout.SOUTH);

How To Change Menu GUI With Buttons

Apr 23, 2014

I have a GUI with a menu to do various options. However I want to change that menu to use buttons instead. I'm working with JSwing components and I'm a little familiar with the JButton function, but I don't know how to convert the menu to a button. I think I'll have to remove the menu completely..anyway I tried to start with the file menu but the compiler says no suitable method found for setForeground(javax.swing.JMenu). Why is it giving me an error related to JMenu when I'm using Jbutton objects? Can I not use JButton objects inside a menubar scope? I'll bold the area it highlighted:

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
