jtable would like to handle both single click and double click

[steve labar]

I have a jtable where i'd like the followiung to occur:

single click: do one thing
double click: do an other

Problem is if i double click it executing both the single then double. Since both have tasks that read same file im getting major issues. Why would this be happening anyfixes?

i tried using double click on one and mouse pressed on another same problem......very strange

     class TableListener implements MouseListener
    {
		@Override
		public void mouseClicked(MouseEvent e) {
			// TODO Auto-generated method stub
			if (e.getClickCount() == 2)
			{
							
				Thread worker = new Thread()
				{
					
					public void run()
					{
						// something that takes a long time . . . in real life, this
						// might be a DB query, remote method invocation, etc.
						try
						{
							  VulnInfo xss = null;
						      int position = jTable1.getSelectedRow();
						     // xss =  xssinfoList.get(position);
						      
						      for(int i=0; i <= position;i++)
						      {
						    	xss = (VulnInfo) ser.readObject();
						      }

oh that mouse click == 5 was ==1 i just was playing around w/ options forgot to change it back!

Problem is if i double click it executing both the single then double. Why would this be happening?

Yes, because thats the way applications are normally designed.

a) a single click selects the item
b) a double click performs some action on the item

And that is why you can also use the keyboard:

a) the arrow keys are used to select an item
b) the Enter key would then typically before an action on the item (although for a JTable the default is to just move to the next row you can always write a custom Action).

Since both have tasks that read same file

Sounds to me like a bad design. Remember what I suggested above. Whatever you can do with the mouse you should be able to do with the keyboard. So it does not make sense to read a file every time you use an arrow key.

But, strangely enough you are not the first person to ask for something like this and I happen to have some old code lying around:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;

public class ClickListener extends MouseAdapter implements ActionListener
{
	private final static int clickInterval = (Integer)Toolkit.getDefaultToolkit().
		getDesktopProperty("awt.multiClickInterval");

	MouseEvent lastEvent;
	Timer timer;

	public ClickListener()
	{
		this(clickInterval);
	}

	public ClickListener(int delay)
	{
		timer = new Timer( delay, this);
	}

	public void mouseClicked (MouseEvent e)
	{
		if (e.getClickCount() > 2) return;

		lastEvent = e;

		if (timer.isRunning())
		{
			timer.stop();
			doubleClick( lastEvent );
		}
		else
		{
			timer.restart();
		}
	}

	public void actionPerformed(ActionEvent e)
	{
		timer.stop();
		singleClick( lastEvent );
	}

	public void singleClick(MouseEvent e) {}
	public void doubleClick(MouseEvent e) {}

	public static void main(String[] args)
	{
		JFrame frame = new JFrame( "Double Click Test" );
		frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
		frame.addMouseListener( new ClickListener()
		{
			public void singleClick(MouseEvent e)
			{
				System.out.println("single");
			}

			public void doubleClick(MouseEvent e)
			{
				System.out.println("double");
			}
		});
		frame.setSize(200, 200);
		frame.setVisible(true);
	 }
}
