how to add a checkbox into JList (java netbeans)?

I have added a checkbox into JList its working successfully but problem is it not select multiple checkbox in same time and the multi-selection code for checkbox not working and I also add the image.
lstsubsub.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
public class CheckboxListCellRenderer extends JCheckBox implements
ListCellRenderer {
#Override
public Component getListCellRendererComponent(JList list, Object value, int index,
boolean isSelected, boolean cellHasFocus) {
setComponentOrientation(list.getComponentOrientation());
setFont(list.getFont());
setBackground(list.getBackground());
setForeground(list.getForeground());
setSelected(isSelected);
setEnabled(list.isEnabled());
setText(value == null ? "" : value.toString());
return this;
}
}

Don't use a JList for the JCheckBoxes... Use a JPanel with GridLayout like so:
import java.awt.GridLayout;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Main extends JPanel {
private final JCheckBox checkReg, checkPerm, checkAcc;
public Main() {
super(new GridLayout(0, 1)); //1 column, any number of rows...
super.add(checkReg = new JCheckBox("User Registration"));
super.add(checkPerm = new JCheckBox("User Permission"));
super.add(checkAcc = new JCheckBox("User Accounts"));
}
public static void main(final String[] args) {
final JFrame frame = new JFrame("List of checkboxes");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(new Main());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
}

Change color of selection (after selection) in a JComboBox

I'm writing a GUI using Swing. I have a custom written JComboBox using a ListCellRenderer and a BasicComboBoxEditor.
In my getListCellRendererComponent() method I change the color of the the list based on whether the item is "selected" (mouse is hovering above), which is nice and all, but I don't want the selection to change background color once a choice is made, which it currently does.
The first picture shows how the interface looks before a selection is made, and the second one shows how it looks after.
QUESTION
How do I change the background of the "selection" to the "stockColor"?

EDIT
I've added a MCVE and as you can see it is the "problem" that the JComboBox is focused that has to do with my issue. I've placed a button next to the ComboBox to help with removing the focus from the ComboBox.
Simply doing a setFocusable(false) would fix it, but also take away some of the functionality of the rest of the program, so this is not desired.

for better help sooner post an SSCCE / MCVE, short, runnable, compilable, with hardcoded value for JComboBox / XxxComboBoxModel in local variable
JList has Boolean array implemented as default in API (no idea whats hidden in
String trueFalseItem = Boolean.toString(tempValue); and with value stored JComboBox model)
this is just code minimum to test isSelected and to change JList.setSelectionXxx inside DefaultListCellRenderer
for example (code in SSCCE / MCVE form)
.
.

import java.awt.Component;
import java.awt.event.ActionEvent;

if (isSelected) {

list.setSelectionBackground(Color.RED);
}
}
return l;
}
return c;
}
});
JFrame frame = new JFrame("");

Here is a short demo of 2 JCombos, one of which will not change its background color when selected :
public static void main(String[] args){
JFrame frame = new JFrame("Combos BG Color test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo(null);
frame.getContentPane().setPreferredSize(new Dimension(400, 40));
JPanel mainPanel = new JPanel();
mainPanel.setLayout(new GridLayout(1,2));
frame.add(mainPanel);
JComboBox<String> aCombo = new JComboBox<>(new String[]{"A","B","C"});
mainPanel.add(aCombo);
JComboBox<String> bCombo = new JComboBox<>(new String[]{"1","2","3"});
Color bgColor = bCombo.getBackground();
bCombo.setRenderer(new DefaultListCellRenderer() {
#Override
public void paint(Graphics g) {
setBackground(bgColor);
super.paint(g);
}
});

add JButton after last row of JTable

I searched for the answer for quite awhile , but most cases were different from mine.
I want to add a JButton directly after the last row of the table, the table is dynamic and is inside a scrollPane.
almost all of the other questions were answered with a button added after scrollPane in BorderLayout.South , which is not what i want.
thanks
updated the picture to better represent it, the button should appear inside the scrollPane just after the last row.

Read more about different LayoutManager's. Use proper manager or combination of them.
Here is simple example:
import java.awt.BorderLayout;
import java.awt.FlowLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class TestFrame extends JFrame {
public TestFrame() {
init();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
setLocationRelativeTo(null);
setVisible(true);
}
private void init() {
JTable t = new JTable(3,3);
add(new JScrollPane(t));
JPanel btns = new JPanel(new FlowLayout(FlowLayout.LEFT,0,0));
JButton jButton = new JButton("here");
btns.add(jButton);
add(btns,BorderLayout.SOUTH);
}
public static void main(String args[]) {
new TestFrame();
}
}
EDIT:
Try to use next example:

How can i do this help me?
Thanks in advance

You want to look as a custom ListCellRenderer. You can look at Provding a Custom Renderer for JComboBox. It the same for a JList. The tutorial over-complicates a bit for simple scenarios. They extends JLabel and implements ListCellRender where you have to implement a few unnecessary things if you just want basic functionality but with am image.
You can just instead extends or create a anonymous DefaultListCellRender and just get the JLabel render component and add to it, like setting Font and ImageIcon. Something like this
public class MarioListRenderer extends DefaultListCellRenderer {
Font font = new Font("helvitica", Font.BOLD, 24);
#Override
public Component getListCellRendererComponent(
JList list, Object value, int index,
boolean isSelected, boolean cellHasFocus) {
JLabel label = (JLabel) super.getListCellRendererComponent(
list, value, index, isSelected, cellHasFocus);
label.setIcon(imageMap.get((String) value));
label.setHorizontalTextPosition(JLabel.RIGHT);
label.setFont(font);
return label;
}
}
What happens is that each cell uses this renderer and calls the getListCellRendererComponent method. The value you see passed to the method is the value in each cell, in my case, one of the character names in the list. I then map that to the corresponding ImageIcon and set the Icon on the JLabel renderer component.
import java.awt.Component;
import java.awt.Dimension;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.SwingUtilities;
public class MarioList {
private final Map<String, ImageIcon> imageMap;
public MarioList() {
String[] nameList = {"Mario", "Luigi", "Bowser", "Koopa", "Princess"};
imageMap = createImageMap(nameList);
JList list = new JList(nameList);
list.setCellRenderer(new MarioListRenderer());
JScrollPane scroll = new JScrollPane(list);
scroll.setPreferredSize(new Dimension(300, 400));
JFrame frame = new JFrame();
frame.add(scroll);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
public class MarioListRenderer extends DefaultListCellRenderer {
Font font = new Font("helvitica", Font.BOLD, 24);
#Override
public Component getListCellRendererComponent(
JList list, Object value, int index,
boolean isSelected, boolean cellHasFocus) {
JLabel label = (JLabel) super.getListCellRendererComponent(
list, value, index, isSelected, cellHasFocus);
label.setIcon(imageMap.get((String) value));
label.setHorizontalTextPosition(JLabel.RIGHT);
label.setFont(font);
return label;
}
}
private Map<String, ImageIcon> createImageMap(String[] list) {
Map<String, ImageIcon> map = new HashMap<>();
for (String s : list) {
map.put(s, new ImageIcon(
getClass().getResource("/marioscaled/" + s + ".png")));
}
return map;
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new MarioList();
}
});
}
}
Side Note
AndrewThompson is correct about just checking the tutorial first. You could have easily found an example implementation, then tried it out. Swing tutorials can be found here. Look under the Using Swing Components for how to use different components.
Swing apps should be run on the Event Dispatch Thread (EDT). You can do so by wrapping your creatAndShowGui() in a SwinUtilities.invokeLater.... See more at Initial Threads

Paint jtable cell editor above jtable

Designing a custom JTable I already know that DefaultCellEditor admits a JComboBox in his constructor. This JComboBox, when clicked to display the list items, shows above the other cells of the JTable. The problem is that I need a more sophisticated behavior as what JComboBox offers, so that I've implemented a JTextField with a JList and a JButton, when the JButton gets clicked (or the user enters text in the JTextField) the elements in the JList become visible. This 3 elements are in a JPanel. When I try to use this panel as a cell editor (extending AbtractCellEditor and implementing TableCellEditor) the elements in the list show inside the editing cell but I cannot mimic the behavior of the DefaultCellEditor with the combo so that the list elements show above the JTable.
Here I define the custom cell editor: (very short version);
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.AbstractCellEditor;
import javax.swing.JButton;
import javax.swing.JList;
import javax.swing.JPanel;
import javax.swing.JTable;
import javax.swing.JTextField;
import javax.swing.table.TableCellEditor;
public class CustomCellEditor extends AbstractCellEditor implements TableCellEditor {
private JList list;
private JButton button;
private JTextField editor;
private JPanel mainPanel;
public CustomCellEditor() {
list = new JList(new String[] { "One", "Two", "Three" });
editor = new JTextField();
button = new JButton("Click me ");
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
list.setVisible(!list.isVisible());
}
});
JPanel auxPanel = new JPanel(new BorderLayout());
auxPanel.add(editor, BorderLayout.CENTER);
auxPanel.add(button, BorderLayout.EAST);
mainPanel = new JPanel(new BorderLayout());
mainPanel.add(auxPanel, BorderLayout.NORTH);
mainPanel.add(list, BorderLayout.CENTER);
}
#Override
public Object getCellEditorValue() {
return editor.getText();
}
#Override
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
return mainPanel;
}
}
And this a main program with a jtable with this panel as a cell editor:
import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.JTable;
import javax.swing.SwingUtilities;
import javax.swing.table.AbstractTableModel;
import javax.swing.table.TableColumn;

});
}

JTable table = new JTable(new CustomTableModel());
//So that I can see the contents of the list when edited
table.setRowHeight(60);
TableColumn editableColumn = table.getColumnModel().getColumn(0);
editableColumn.setPreferredWidth(250);
editableColumn.setCellEditor(new CustomCellEditor());
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(table, BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
}
private class CustomTableModel extends AbstractTableModel {
private final String[] columnNames = {"Editable column", "Other column"};
private final Object[][] data = {
{"Ricardo", "Mr."},
{"Josefina", "Ms."}
};
#Override
public int getRowCount() {
return data.length;
}
#Override
public int getColumnCount() {
return columnNames.length;
}
#Override
public Object getValueAt(int rowIndex, int columnIndex) {
return data[rowIndex][columnIndex];
}
#Override
public boolean isCellEditable(int row, int col) {
if (0 == col)
return true;
return false;
}
#Override
public void setValueAt(Object value, int row, int col) {
data[row][col] = value;
fireTableCellUpdated(row, col);
}
}
}
Can someone help me?
Thanks!!

Using a JComboBox as a table editor relies on it being a button that displays a popup component when pressed. As you have several components in a cell, consider these alternatives:
Add the components to a panel, as shown here for a group of JRadioButton instances.
Add the components to a modal dialog, as shown here using JDialog.
