Clipboard
I need to copy the value of one JTable field to Clipboard. I'm not understanding how this mecanism works. Can some give me: Good explanation. Reference to a article with this information. Some simple working code. Since Drag and drop seem to use a similar interface and I will need to do it, in one week, I estend the question to this as well.

Bringing one JInternalFrame to the front of the JDesktopPane
I'm using one JDesktopPane in my project and I need to set one
JInternalFrame in front of all the other and selected. Until know this is
the better I can do. If the JInternalFrame is iconifyed this don't work. I
know this must be a very simple thing to do but I don't find how.

Thanks, seems to be perfect.
In the end of this work I shall write a book called Tips for real dummy

Calling just the desktop manager method only does part of the job and
leaves the state inconsistent.
This code should fix your problem:
pnButtons.add(new JButton(new AbstractAction(Open 1){
public void actionPerformed(ActionEvent arg0) {
try
{
ifr1.setIcon(false);
ifr1.setSelected(true);
} catch( java.beans.PropertyVetoException e ) {}
ifr1.toFront();
}
}));
pnButtons.add(new JButton(new AbstractAction(Open 2){
public void actionPerformed(ActionEvent arg0) {
try
{
ifr2.setIcon(false);
ifr2.setSelected(true);
} catch( java.beans.PropertyVetoException e ) {}
ifr2.toFront();
}
}));

Path Files
In my program I'm using ImageIcon for the buttons and I had this code
Action actClose = new AbstractAction(Close, new
ImageIcon(images/file_close.gif)){...}
This works if I'm in the correct directory, but if I'm not the images are
not found.
What is the correct way to do the previus code?
Thanks

Add new lines to the JTable
What is the better way to add lines to a JTable. I have my TableModal and I
add one line to the Model, know I need the line to apear in the interface.
The only way that I get it to work is with the line
'scrollPane.getViewport().add(table);' (I tryed allot of things before I get
here).
What is the correct way to do it?
This is a simple code showing my problem.
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import javax.swing.table.AbstractTableModel;
class MyTableModel extends AbstractTableModel {
int nRows = 5;
public int getRowCount() {
return nRows;
}
public int getColumnCount() {
return 4;
}
public Object getValueAt(int arg0, int arg1) {
return new Integer(arg0*arg1);
}
void IncrementRow() {
nRows++;
}
}
public class Main {
static JFrame m_frame;
public static void main(String[] ARGS) {
m_frame = new JFrame(Teste);
m_frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
m_frame.getContentPane().setLayout(new BorderLayout());
final JTable table = new JTable();
final MyTableModel myTableModel = new MyTableModel();
table.setModel(myTableModel);
final JScrollPane scrollPane = new JScrollPane(table);
m_frame.getContentPane().add(scrollPane, BorderLayout.SOUTH);
JButton bt = new JButton(XXX);
bt.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent arg0) {
myTableModel.IncrementRow();
scrollPane.getViewport().add(table);
}
});
m_frame.getContentPane().add(bt, BorderLayout.NORTH);
m_frame.pack();

RE: Add new lines to the JTable
Thanks for this answer, I look in the table and I never remember to go to
the TableModel.
Onether question. Know I have the Table with the cells editable.
If I chose another column the setValueAt is called.
If I press the button the setValueAt is not called.
If I go to the TextArea the setValueAt is not called.
if I close the Frame the setValueAt is not called.
This isn't suposed?
Simple code. I'm seeing just the output.

For the JLabel works but for the JTable don't.
In the Cell case I'have to know the Row as well.

Limits in JTable
This is one of the most strange error that I ever found.
If I run the some code in Windows NT works, in a sun workstation works and
in Window throw Exceed to a sun worstation don't work.
With this code works in the 3:
import javax.swing.*;
import javax.swing.table.*;
public class Main {
static JFrame m_frame;
public static void main(String[] ARGS){
m_frame = new JFrame(Teste);
m_frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JTable table = new JTable();
table.setModel(new AbstractTableModel(){
public int getRowCount() {
return 2047;
}
public int getColumnCount() {
return 436;
}
public Object getValueAt(int arg0, int arg1) {
return new Integer(arg0*arg1);
}});
table.setAutoCreateColumnsFromModel(false);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
JScrollPane scrollPane = new JScrollPane(table);
m_frame.getContentPane().add(scrollPane);
m_frame.pack();
m_frame.setVisible(true);
}
}
Know if I change
public int getRowCount() {
return 2047;
}
to
public int getRowCount() {
return 2048;
}
Or if I change
public int getColumnCount() {
return 436;
}
to
public int getColumnCount() {
return 437;
}
I get problems.
When I do scroll the table has problems whith the refrescement, seems that
background of the cell in the JTable are not painted but if I resize the
Frame the repaint is done with a wrong color. Probably the JScrollPanel
color, I don't know.
This error just occores in the exceed.
Thanks

Dialog for Open one File
I need a Open file Dialog.
I was seeing the JFileChooser and I did this class.
public class JDialogFileOpen extends JFileChooser {
public int showDialog(Component arg0, String arg1)
throws HeadlessException {
while (true) {
int nOption = super.showDialog(arg0, arg1);
if (nOption != JDialogFileOpen.APPROVE_OPTION) {
return nOption;
} else {
File file = this.getSelectedFile();
if (file.exists() file.isFile()) {
return nOption;
} else {
JOptionPane.showMessageDialog(
this,
file.getPath()+\nFile not found.,
null,
JOptionPane.ERROR_MESSAGE);
}
}
}
}
}
When the file does not exists shows a error message and reshow the
JFileChooser.
I don't want the JFileChooser to desapear. Is this possible?

Setting new JPane to a JFrame.
This is the most simple code that I found to show this error.
I have JFrame with a complex Content Pane (not this one). I'm trying to
recreate the Content pane for each File but after I set the new Content Pane
there is no Change, But if I try to resize the new Pane alredy apears.
What do I need to set this simple example to work?
