how to use custom cell rendering in jtable for the below needs? [duplicate]

I would like to make an editable table and then check the data to make sure its valid. Im not sure how to change the color of just one cell. I would like to get a cell, for example (0,0) and color the foreground to red. I have read the other posts on SO as well as Oracle about the custom ColorRenderer, but i just don't get how i would use this.
Thanks.

Say that the cell you would like to render with a different color represents a status (I'll take Rejected and Approved as examples). I'd then implement a method in my table model called getStatus(int row) which returns the status for any given row.
Then, when that is in place, I'd go about creating a cell renderer responsible for rendering the column which the cell belongs to. The cell renderer would be something in the lines of the below code.
public class StatusColumnCellRenderer extends DefaultTableCellRenderer {
#Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int col) {
//Cells are by default rendered as a JLabel.
JLabel l = (JLabel) super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, col);
//Get the status for the current row.
CustomTableModel tableModel = (CustomTableModel) table.getModel();
if (tableModel.getStatus(row) == CustomTableModel.APPROVED) {
l.setBackground(Color.GREEN);
} else {
l.setBackground(Color.RED);
}
//Return the JLabel which renders the cell.
return l;
}
Then, when the renderer is in place, simply "apply" the renderer to the table with the following piece of code:
Table.getColumnModel().getColumn(columnIndex).setCellRenderer(new StatusColumnCellRenderer());
With regard to making a cell editable, simply implement the isCellEditable(int rowIndex, int columnIndex) method in your table model. You also need to implement the method
setValueAt(Object value, int rowIndex, int columnIndex) if you would like to keep the value which the user provides (which i assume you do!).

I would like to make an editable table and then check the data to make sure its valid.
Another approach would be to edit the data before it is saved to the table model to prevent invalid data from being entered.

public class TableEdit extends JFrame
{
TableEdit()
{
JTable table = new JTable(5,5);
table.setPreferredScrollableViewportSize(table.getPreferredSize());
JScrollPane scrollpane = new JScrollPane(table);
getContentPane().add(scrollpane);
// Use a custom editor
TableCellEditor fce = new FiveCharacterEditor();
table.setDefaultEditor(Object.class, fce);
}
class FiveCharacterEditor extends DefaultCellEditor
{
FiveCharacterEditor()
{
super( new JTextField() );
}
public boolean stopCellEditing()
{
try
{
String editingValue = (String)getCellEditorValue();
if(editingValue.length() != 5)
{
JTextField textField = (JTextField)getComponent();
textField.setBorder(new LineBorder(Color.red));
textField.selectAll();
textField.requestFocusInWindow();
JOptionPane.showMessageDialog(
null,
"Please enter string with 5 letters.",
"Alert!",JOptionPane.ERROR_MESSAGE);
return false;
}
}
catch(ClassCastException exception)
{
return false;
}
return super.stopCellEditing();
}
public Component getTableCellEditorComponent(
JTable table, Object value, boolean isSelected, int row, int column)
{
Component c = super.getTableCellEditorComponent(
table, value, isSelected, row, column);
((JComponent)c).setBorder(new LineBorder(Color.black));
return c;
}
}

I believe the correct way to do colouring in a table is via a ColorHighlighter. The table renderers have problems to render different colours in the same column.
Here is an example of how to use highlighters. In this case it is for highlighting a cell that is not editable.
public class IsCellEditablePredicate implements HighlightPredicate {
private JXTable table;
public IsCellEditablePredicate (final JXTable table) {
this.table = table;
}
#Override
public boolean isHighlighted(Component component, ComponentAdapter componentAdapter) {
return !table.isCellEditable(componentAdapter.row,
componentAdapter.column);
}
}
and then in your code for setuping the table you add the highlighter and its colour parameters:
ColorHighlighter grayHighlighter = new ColorHighlighter(new IsCellEditablePredicate(table));
grayHighlighter.setBackground(Color.LIGHT_GRAY);
grayHighlighter.setForeground(table.getForeground());
grayHighlighter.setSelectedBackground(table.getSelectionBackground().darker());
grayHighlighter.setSelectedForeground(table.getSelectionForeground().darker());
table.setHighlighters(grayHighlighter);

This is the simplest way to color a particular Column or cell in a jTable.
First just create a simple class of CustomRenderer
class CustomRenderer extends DefaultTableCellRenderer <br />
{
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
{
Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
setForeground(Color.blue); >
return c;
}
}
This code gets the column of cell to render
TableColumn col = tblExamHistoryAll.getColumnModel().getColumn(5);
DefaultTableModel model3 = (DefaultTableModel)tblExamHistoryAll.getModel();
col.setCellRenderer(new CustomRenderer());
This is to clear all previous rows from your table. If you do not want them just remove these lines
model3.getDataVector().removeAllElements();
model3.fireTableDataChanged();

#Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus,
int row, int col) {
Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, col);
int control = row;
control = control % 2;
control = (control == 0) ? 1 : 0;
if (control == 1) {
c.setBackground(Color.green);
} else {
c.setBackground(Color.cyan);
}
return c;
}

The most straightforward way is to write a simple TableCellRenderer by extending the DefaultTableCellRenderer and overwriting the getTableCellRendererComponent method to setBackground( Color.RED ). For example:
final JTable table = new JTable(...);
table.setCellRenderer( new DefaultTableCellRenderer() {
public Component getTableCellRenderer(JTable table, Object value, ...) {
super.getTableCellRenderer(...);
if ( value should be highlighted ) {
setBackground( Color.RED );
}
return this;
}
});

You can extend DefaultTableCellRenderer, override getTableCellRendererComponent and call something like
if (myConditions) setBackground(myColor);
before returning "this" when conditions apply but it has a very annoying side-effect of changing the default back-color due to the way DefaultTableCellRenderer.setBackGround is coded.
The trick I found was to entirely duplicate the code of DefaultTableCellRenderer in a class named HackedDefaultTableCellRenderer, add a method that calls directly the Component's setBackground implementation:
public void setComponentBackground(Color c) {
super.setBackground(c);
}
then derive my customized rendered from this hacked class instead of from DefaultTableCellRenderer, and finally call setComponentBackground instead of setBackground in my customized getTableCellRendererComponent.
The drawback is that this HackedDefaultTableCellRenderer relies on a snapshot of DefaultTableCellRenderer.

JAVA - How to change JTable row color after clicking on it?

I 'm a Java beginner.
I create an application with a JTable which is populated with a database.
In my database I have some 'news'. In my JTable I display titles of 'news' and when an user click on a row, it display a popup with the right contents of the news.
But I want to colorize the cell which are 'read' when the user clicked on it.
I use my own TableModel.
I hope I'm clear...
If I need to put some code, tell me what please...

public class JTableTest extends JFrame {
private JTable table;
private int col;
private int rowz;
/**
* Create the frame.
*/
public JTableTest() {
initComponents();
}
private void initComponents() {
/** any other components */
table = new JTable();//create the table
table.setDefaultRenderer(Object.class, new CustomModel());
table.addMouseListener(new CustomListener());
}
public class CustomListener extends MouseAdapter {
#Override
public void mouseClicked(MouseEvent arg0) {
super.mouseClicked(arg0);
//get the clicked cell's row and column
rowz = table.getSelectedRow();
col = table.getSelectedColumn();
// Repaints JTable
table.repaint();
}
}
public class CustomModel extends DefaultTableCellRenderer {
private static final long serialVersionUID = 1L;
#Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
JLabel label = (JLabel) super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
Color c = Color.WHITE;//define the color you want
if (isSelected && row == rowz & column == col)
c = Color.GREEN;
label.setBackground(c);
return label;
}
}
}

Found this example of how to get the table cell on mouseClick: http://codeprogress.com/java/showSamples.php?index=52&key=JTableValueofSelectedCell
You can use this to get the selected row and column.
Then you need to create a custom TableCellRenderer, possibly as an inner class so that it can use the selected row and column data and set the background of the cell to your highlighted color

Usability features for JComboBox within JTable

I'm trying to build a table which includes JComboBoxes as both the renderer and editor components. This mostly works fine, however there are two things I can't seem to solve.
Tabbing between cells should make the JComboBox active
Clicking the drop-down arrow should immediately open the option list
Regarding 1, the editable combo should place focus within the embedded text field, the fixed combo should allow the down arrow to open the list of options.
Regarding 2, I find that this sometimes works depending on what other cell is currently active, but other times I have to double click. I cannot make this behaviour consistent.
For convenience I have included a clear example which (I believe) uses the recommended approach for embedding JComboBoxes within Jtables.
Thank you for constructive advice.

Both of your issues be resolved by overriding the DefaultCellEditor#isCellEditable method and returning true
You may need to set JTable#setSurrendersFocusOnKeystroke to true as well
Update
The short answer is "It's messy". The long answer is "it's very messy"
I did a "continuos editing" process some time back. Basically, I overrode the Enter and Tab key bindings.
What I'd did was basically stop any active cell editor, take note of the current cell and then tried to finding the next editable cell, looping back around to the start (cell 0x0) if required.
When I found a editable cell, I called JTable#esitCellAt to start editing the cell.
To get the popup to be visible when the cell starts editing, you will need to override the addNotify method of the JComboBox and, using SwingUtilities#invokeLater, set the popup visible

JTable Calls Custom Cell Renderer Method... Continuously

Compilable source can be found at: http://www.splashcd.com/jtable.tar
I'm new to the language, so I'm not sure if this is acceptable behavior or not.
I created a JTable to display a row for each message received (it receives about
one every 20 seconds). One of the table columns can contain a large amount of
text, so I created a custom cell renderer which word wraps and sets the row
height accordingly.
All that works as expected, except that once the table displays its first row,
it calls the cell renderer about ten times a second... until the user closes the
table.
Once I get approx 20 rows in there, the table gets fairly sluggish, taking 2-8
seconds to resize a column, scoll up or down, or render a selected row with the
selected background color.
I inserted a print statement inside the renderer, so I can see how many times
the getTableCellRendererComponent method is being called.
I disabled tool tips, and disabled all cell editing. I do have a listener that
scrolls the view to the last row when either a new row is added or the table is
resized.
Should the getTableCellRendererComponent method be called several times a second
when I'm just viewing the screen (not touching mouse or keyboard)?
TIA

aaaaach
you need doLayout(),

To get the most performance out of a TableCellRenderer, make sure you're not creating a new instance of a component every time getTableCellRenderer is called. Make the components once and save them as fields of the class.
Also, you'll want to make sure each of the Components you use have the following methods overridden to do nothing:
validate
invalidate
revalidate
repaint
firePropertyChange
(and you probably want to hard code isOpaque).
For more information see: http://docs.oracle.com/javase/6/docs/api/javax/swing/tree/DefaultTreeCellRenderer.html

The problem seems to stem from having JTable's setRowHeight() inside the custom cell renderer, as it calls the custom cell renderer, throwing it into an infinite loop.
I had to add in a check to see if the current row height matched the calculated word wrapped row height. If it did, I didnt try to setRowHeight() again.
Corrected Code:
import java.awt.Component;
import javax.swing.JTable;
import javax.swing.JTextArea;
import javax.swing.UIManager;
import javax.swing.table.TableCellRenderer;
//custom cell renderer for word wrapping, but if you use, you have to
//implement zebra striping functionality which the default renderer has
public class LineWrapCellRenderer extends JTextArea implements TableCellRenderer
{
private int numOfTimesCalled;
#Override
public Component getTableCellRendererComponent(
JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row,
int column)
{
System.out.println("Line Wrap Cell Renderer Called: " + numOfTimesCalled++);
System.out.println("row:"+ row + ", col:" + column);
//set up the row size based on the number of newlines in the text in the cell
int fontHeight = this.getFontMetrics(this.getFont()).getHeight();
int numWraps = value.toString().split("\r\n|\r|\n").length;
int rowHeight = fontHeight * numWraps;
//if the calculated rowHeight is the same as the row height of row,
// then don't call setRowHeight again, as doing so will throw us into
// an infinite loop
if(rowHeight != table.getRowHeight(row))
{
table.setRowHeight(row, rowHeight);
//configure word wrapping
setWrapStyleWord(true);
setLineWrap(true);
//use the table's font
setFont(table.getFont());
}
//zebra striping, because whatever cell uses this renderer loses the
//default cell renderer zebra striping
if(isSelected)
{
setBackground(table.getSelectionBackground());
}
else
{
if(row%2 == 1)
{
setBackground(UIManager.getColor("Table.alternateRowColor"));
}
else
{
setBackground(table.getBackground());
}
}
this.setText(value.toString());
return this;

Refresh JTable after look and feel update

I have a JTable with custom TableCellRenderer.
public class DateCellRenderer extends DefaultTableCellRenderer {
private static final long serialVersionUID = 58L;
public DateCellRenderer() {
super();
setHorizontalAlignment(CENTER);
setOpaque(true);
}
#Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
if (value instanceof Date) {
String date = new SimpleDateFormat("dd-MM-yyyy").format((Date) value);
setText(date);
}
return this;
}
}
Also in my application I have a drop down menu by which I can change the look and feel. This drop down menu is in a parent frame and the table is in a dialog. When the dialog is opened the parent frame is inaccessible. So to change the look and feel I have to close the dialog first.
Now in a particular skin if the table is populated by some data and I change the look and feel from parent frame and again open the dialog then the column, where I have added the TableCellRenderer, is keeping the old look and feel. It is not updating while the other columns render themselves in the new look and feel.
I am unable to find the problem and its solution. Any help is appreciable.
Note: The look and feel update of the application is made by the following snippet
javax.swing.UIManager.setLookAndFeel(uiProperties.getThemeModel().getThemeClass());
ComponentFactory.getLibraryFrame().getRootPane().updateUI();
for (int i = 0; i < Frame.getWindows().length; i++) {
SwingUtilities.updateComponentTreeUI(Frame.getWindows()[i]);
}
for (int i = 0; i < Frame.getFrames().length; i++) {
SwingUtilities.updateComponentTreeUI(Frame.getFrames()[i]);
}
Thanks in advance.
In HiFi theme chosen first:
Then I change the theme to Fast, and the second column "Released" not updated its ui:
The JTable is:
public class MovieSearchResultTable extends BaseTable {
private static final long serialVersionUID = 45L;
public MovieSearchResultTable(TableModel tableModel) {
super(tableModel);
LibraryLogger.initMessage(getClass().getSimpleName());
}
#Override
public void initialize() {
setFillsViewportHeight(true);
setAutoResizeMode(AUTO_RESIZE_OFF);
getColumnModel().getColumn(1).setCellRenderer(new DateCellRenderer());//if I comment out this line then no problem. but without CellRenderer how could I format a Date, if I use formatted String instead of Date, then the column will not sort!!
}
#Override
public boolean getScrollableTracksViewportWidth() {
return getPreferredSize().getWidth() < getParent().getWidth();
}
}

I think that not good L&F, JTable looks like ... ok, but other Compound JComponents aren't ...., not sure I haven't wasting my time, I leaving to test that, maybe is there something described about that on their Forum or Documentation or BugParades, but nothing from your question
there is very simple way and you can any time to check that
1) go to Insubstantial
2) download code source,
3) import all classes to the IDE (2-15 min depends of PC HardWare)
4) search for folder test, there is Check.java,
5) run that and to try everything in JMenu Look and Feel, before that required to download API's for every Custom Java Swing Look and Feels

The solution, you need to override public Component prepareRenderer(TableCellRenderer renderer, int row, int column)
Here is the class:
public class MovieSearchResultTable extends BaseTable {
private static final long serialVersionUID = 45L;
private int rolloverRowIndex = -1;
public MovieSearchResultTable(TableModel tableModel) {
super(tableModel);
LibraryLogger.initMessage(getClass().getSimpleName());
}
public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
Component component = super.prepareRenderer(renderer, row, column);
Color foreground = getForeground();
Color background = getBackground();
if (isRowSelected(row)) {
foreground = getSelectionForeground();
background = getSelectionBackground();
}
else if (row == rolloverRowIndex) {
foreground = getSelectionForeground();
background = ColorHelper.brighter(getSelectionBackground(), 40);
}
else if (row % 2 == 0) {
background = ColorHelper.brighter(getParent().getBackground(), 20);
}
component.setForeground(foreground);
component.setBackground(background);
return component;
}
private class RolloverListener extends MouseInputAdapter {
public void mouseExited(MouseEvent e) {
rolloverRowIndex = -1;
repaint();
}
public void mouseMoved(MouseEvent e) {
int row = rowAtPoint(e.getPoint());
if (row != rolloverRowIndex) {
rolloverRowIndex = row;
repaint();
}
}
}
#Override
public void initialize() {
setFillsViewportHeight(true);
setAutoResizeMode(AUTO_RESIZE_OFF);
TableColumnModel tableColumnModel = getColumnModel();
for(ComponentConstant.ColumnName columnName : ComponentConstant.Column.MOVIE_SEARCH_RESULT_TABLE) {
int order = columnName.getOrder();
TableColumn tableColumn = tableColumnModel.getColumn(order);
if(order == 0) {
continue;
}
tableColumn.setCellRenderer(RendererFactory.getMovieSearchResultTableCellRenderer());
}
RolloverListener listener = new RolloverListener();
addMouseMotionListener(listener);
addMouseListener(listener);
}
#Override
public boolean getScrollableTracksViewportWidth() {
return getPreferredSize().getWidth() < getParent().getWidth();
}
}
Thanks.
