How to use Jtable cell Editor

HI,
Here trying to populate the ImageIcon using JLabel in Jtable cell. For that I used DefaultCellRenderer. For implement the mouseListener to label I used the DefaultCellEditor. I am facing one problem here. After editing the label I selected the second row of the table, the first row image is not displaying. Can any one help on this issue?
public class LabelCellEditor extends DefaultCellEditor {
public LabelCellEditor(final JCheckBox checkBox) {
super(checkBox);
public Component getTableCellEditorComponent(final JTable table, final Object value,
final boolean isSelected, final int row, final int column) {
Color background = null;
background = ColorManager.SELECTED_ROW_BGCOLOR;
labelVal = (JLabel) value;
labelVal.setOpaque(true);
labelVal.setFont(FontManager.TABLE_DATA_FONT);
labelVal.setBackground(background);
labelPanel = new JPanel();
labelPanel.setOpaque(true);
labelPanel.setBackground(background);
labelPanel.setLayout(new FlowLayout(FlowLayout.LEFT));
labelPanel.setBorder(new EmptyBorder(5, 0, 0, 0));
labelPanel.add(labelVal);
return this.labelPanel;
public Object getCellEditorValue() {
return this.labelPanel;
public class LabelCellRenderer extends DefaultTableCellRenderer {
public LabelCellRenderer(final int alignment) {
//setHorizontalAlignment(alignment);
this.align = alignment;
public Component getTableCellRendererComponent(final JTable table, final Object value,
final boolean isSelected, final boolean hasFocus, final int row, final int column) {
if (value != null) {
if (value instanceof JLabel) {
labelVal = (JLabel) value;
labelVal.setOpaque(true);
labelVal.setFont(FontManager.TABLE_DATA_FONT);
labelVal.setBackground(background);
labelVal.setHorizontalAlignment(this.align);
labelVal.setBorder(new EmptyBorder(0, LRPADD, 0, LRPADD));
JPanel panel = new JPanel();
panel.setOpaque(true);
panel.setBackground(background);
panel.setLayout(new FlowLayout(FlowLayout.LEFT));
panel.setBorder(new EmptyBorder(5, 0, 0, 0));
panel.add(labelVal);
return panel;
return this;
}

With more than 30 postings you should know by now how to use the "Code" tags when posting code so the code reatains its original formatting and is therefore more readable.
There is no need to create a custom editor, here is a simple example.

How to use JTable model listener???

Anyone got idea , how to use table model listener. Can explain in simple example with code?? how to pass back to resultset ??

Well, your pretty good at asking questions, but not very good at thanking people for the help given to you so I don't think I'll waste too much time helping this time.
A TableModelListener notifies you when the contents of a cell are changed. So simply take the data from the cell and update your ResultSet. You question is so general I don't know how you expect any more advice than that.

How to use/populate JTable in Jdev 3.0 ?

Is there any tutorial or examples available
on how to use JTable in JDeveloper 3.0 ?
After creating business objects project
and application, what steps do I take to
a) put a jtable class object into my application ? I have tried creating a
frame (JFrame) using new\objects\frame, and
then dragging JTable into the UI, but don't
know how to connect things from there.
b). manipulate/populate the grid from there
using the business objects created
earlier in the project ?
The html documentation included with JDev 3 provides some clues on individual key word searches, but does not at all connect the dots. What is needed
here is a tutorial like some of the others
included.

You may find the following steps useful.
Create an InfoBus form by:
Select menu File | New...
Select "InfoBus Data Form" and press OK
Go through the wizard and create a
Detail or Master Detail form.
Be sure to place the detail in a GRID control (last few pages of wizard).
Then look at the generated code. This form will contain a useful class GridControl which contains a JTable element. Most noteworthy is that the JTable is already hooked up to the data source.
In particular, the GridControl that is in
your source has a public method:
public final JTable getTable()
This gives you access to the JTable to further customize the way you need.
Ofcourse there are other tutorials that touch
on the above, but you won't find a tutorial
on how to hook up a JTable to a database because we have many more advanced classes
(InfoSwing: GridControl,...) that do that
and much more for you. You will be much more
productive if you rely on the additional InfoSwing components.
I hope this helps,

How to use vector in JTable? Please help......

Hi there
I can use JTable using object array to manupulate data but it has a limitation of defining number of rows of the array. Alternatively i want to use vector. Anyone help me how to convert to using vector.
Regards.
mortoza, Dhaka

hi,
you could either use javax.swing.table.DefaultTableModel because this class uses a java.util.Vector for data storage or you could implements your own TableModel by extending javax.swing.table.AbstractTableModel.
best regards, Michael

How to use TableModel ???????

I'm new to java, please help me
i have this problem. When i choose the item in the combo box for the first time, i get the selected table, but when i choose the other item in combo box, the previous table is still remain in the panel instead of the new one.
String sList[] =
"InformationTechnology",
"Account",
"Investment"
combo = new JComboBox();
combo.setBounds( 220, 35, 260, 25 );
panel3.add( combo );
combo.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
System.out.println("Selected Item = "+(String)combo.getSelectedItem());
TableDisplay((String)combo.getSelectedItem());=
try {
// get column heads
ResultSetMetaData rsmd = rs.getMetaData();
for ( int i = 1; i <= rsmd.getColumnCount(); ++i )
columnHeads.addElement( rsmd.getColumnName( i ) );
// get row data
do {
rows.addElement( getNextRow( rs, rsmd ) );
} while ( rs.next() );
// display table with ResultSet contents
table = new JTable( rows, columnHeads );
scroller = new JScrollPane(table);
scroller.setBounds( 220, 70, 260, 100 );
panel3.add(scroller);
table.validate();
catch ( SQLException sqlex ) {
sqlex.printStackTrace();
just now got a 'guru' told me to use TableModel, but i search the web already but still stuck in the middle, because i don't know how to use TableModel..............

liml,
You code shows table instantiation as:
// display table with ResultSet contents
table = new JTable( rows, columnHeads );
Check that it's in scope, say at class-level, for subsequent manipulations.

How to use TableSorter class with DefaultTableModel

Hi Friends
Please tell me how to use TableSorter Class which is in the Java. Tutorials with DefaultTableModel.
i saw in a thread there it was given that we have to pass the DefaultTableModel to the TableSorter Class.
I tried to use like that. But i am getting Error Like Exception occurred during event dispatching:

Thank you for your service

I don't know about any TableSorter class, but I suppose you mean javax.swing.table.TableRowSorter.
The TableRowSorter is to be attached to the JTable, not to the data model. Here's a cut'n'paste from the last time I used it:
RowSorter<TableModel> sorter = new TableRowSorter<TableModel>(tableModel);
myTable.setRowSorter(sorter);
And heres from the JDK1.6 documentation:
TableModel myModel = createMyTableModel();
JTable table = new JTable(myModel);
table.setRowSorter(new TableRowSorter(myModel));
Check out http://java.sun.com/javase/6/docs/api/javax/swing/table/TableRowSorter.html. I find it to be good documentation.

The Swing tutorial on "How to Use Tables" has examples of how to hardcode a 2-dimensional array to build a TableModel.
http://java.sun.com/docs/books/tutorial/uiswing/components/table.htmlYou can also use the addRow(...) method of the DefaultTableModel to dynamically add rows to a table.

How to update Jtable based on itemStateChanged in JComboBox?

My bad... I originally posted this topic in the Java Programming forum before I found this forum. My apologies.
Anyway, can someone help me out pls? I need to be able to update my JTable based on the selected item in the combobox. Unfortunately, my JTable doesn't update when I choose another item in the combo box. What am I doing wrong? I've read about TableModels but I'm not quite sure how to use it.
my code:
my_constructor()
JComboBox cbdisease;
cbdisease = new JComboBox();
cbdisease.setEditable(false);
cbdisease.setBounds(30,20,270,25);
add(cbdisease);
cbdisease.addActionListener(this);
cbdisease.addItem("View All");
//aside from "View All" that was previously added to the combo box
//get the values from the database to fill the comboBox
showDiseases();
cbdisease.addItemListener(new ItemListener()
public void itemStateChanged(ItemEvent e)
System.out.println(cbdisease.getSelectedItem());
displayRules();
}// end constructor
method: showDiseases
connect to DB and get D_Description (column in database)
display D_Description in combo box
public void showDiseases()
Connection conn = null;
ResultSet rs = null;
Statement statement = null;
try {
// Connect to DB
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql:///dbused",
"root", "");
// create a statement, execute query
statement = conn.createStatement();
rs = statement.executeQuery("SELECT DISTINCT D_Description FROM disease");
//place D_Description in combo box
while(rs.next())
strDesc = rs.getString("D_Description");
cbdisease.addItem(strDesc);
conn.close();
statement.close();
} catch (SQLException sqle) {
sqle.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}//end catch
}//end showDiseases()
method: displayRules
connect to DB and get the rules depending item selected in the combo box
display the rules in a table
public void displayRules()
Connection conn = null;
ResultSet rs = null;
Statement statement = null;
try {
// Connect to DB
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql:///dbused",
"root", "");
// create a statement, execute query
statement = conn.createStatement();
if(cbdisease.getSelectedItem().equals("View All"))
rs = statement.executeQuery("SELECT D_DiseaseCode, D_Description, D_QuestionCode, D_Question, D_Action, D_NumArrow, D_Arrow FROM Disease ORDER BY D_DiseaseCode, D_QuestionCode");
else //query depends on the item selected in combo box other than "View All"
rs = statement.executeQuery("SELECT D_DiseaseCode, D_Description, D_QuestionCode, D_Question, D_Action, D_NumArrow, D_Arrow FROM Disease WHERE" + " D_Description = '" +cbdisease.getSelectedItem()+ "' ORDER BY D_DiseaseCode, D_QuestionCode");
// Convert the result set into an array of Objects
Object[][] rows = getObjects(rs);
// These are the column headings displayed in the JTable
String[] headings = { "Disease Code", "Description", "Question Code", "Question", "Action", "# of Arrows", "Arrow"};
// Initialize a JTable with the rows of objects and column headings
rulestable = new JTable(rows, headings);
// Add the table to a JScrollPane to make it display nicely
rulesScroll = new JScrollPane(rulestable);
// Add the scroll pane to the container
add(rulesScroll);
rulesScroll.setBounds(30,80,720,380);
conn.close();
statement.close();
} catch (SQLException sqle) {
//sqle.printStackTrace();
System.out.println(sqle.getSQLState());
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
}//end displayRules()
method: getObjects
public Object[][] getObjects(ResultSet rs) throws SQLException
// Find out how many columns are in the result set
ResultSetMetaData metaData = rs.getMetaData();
final int colCount = metaData.getColumnCount();
ArrayList rows = new ArrayList();
Object[] row = null;
while (rs.next()) {
// for each row in the result set, put every column into a temporary Object array
row = new Object[colCount];
for (int a = 0; a < colCount; a++)
row[a] = rs.getObject(a+1);
// add the temporary Object array to the array list
rows.add(row);
// convert the array list to objects
return (Object[][])rows.toArray(new Object[0][0]);
}//end getObjects()

Just pass the new data to a new TableModel object's
constructor and then u can use this new table model in
ur JTable constructor. that woud automatically update
the table data.
Cheers!
