MouseEvent on JTable

[Susmitha Metlapalli]

Hi,

I have a JTable with data. I want to generate a single/double click mouse event programatically using java (MouseEvent me = new MouseEvent(source,id,when,x,y,clickcount,popiptrigger) rather than manually clicking on JTable for selecting a specific row...

Is it possible?

In the following program i used setRowSelectionInterval(0,0) for selecting a row programatically. I also have a mouse listener for JTable. But i dont want to use both of these.

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.text.*;
import javax.swing.*;
import javax.swing.table.*;

public class TestJTable
{
public static void main(String args[])
{
TestJTable1 tj = new TestJTable1();
tj.setSize(800,800);
}
}

class TestJTable1 extends JFrame
{
public TestJTable1()
{
JTable jtb = new JTable();

setTitle("TestJTable1");
setVisible(true);

DefaultTableModel model = new DefaultTableModel(10, 10);

for (int i = 0; i < model.getRowCount(); i++)
{
for (int j = 0; j < model.getColumnCount(); j++)
{
model.setValueAt(new Integer((i + 1) * (j + 1)), i, j);

jtb.setModel(model);

Container contentPane = getContentPane();
contentPane.add(new JScrollPane(jtb), "Center");

jtb.addMouseListener(new MouseAdapter()
{
public void mouseClicked(MouseEvent me)
{
System.out.println(me);
}
});

}
}
jtb.setRowSelectionInterval(0,0);
}
}


Thanks in advance,
Susmitha.

MouseEvent me = new MouseEvent(source,id,when,x,y,clickcount,popiptrigger), will simply create the MouseEvent object, but how can you handle the event without the listener?

Use java.awt.Robot.

table.changeSelection(....);

Thanks for the replies.

I have to generate mouse double click event on specific cell of JTable programatically...

I cannot use java.awt.Robot, because i should not make this JFrame visible on the screen... I have to say setVisible(false) at later time...

Please help...

Thanks in advance,
Susmitha.

> I have to generate mouse double click event on specific cell of JTable programatically...

you need to explain 'why' you need to generate a mouse double click event.

normally you would do something like this

mouseListenerEvent(pressed/released/clicked)
{
  if(mouseEvent.getClickCount() == 2)
  {
      //code goes here
  }
}

instead of the above you could do this

mouseListenerEvent(pressed/released/clicked)
{
  if(mouseEvent.getClickCount() == 2)
  {
      doSomething();
  }
}
public void doSomething()
{
  //code goes here
}

and instead of trying to generate a mouse double-click event, you just call doSomething()
