popup menu should be visible with in the associated component

OK, now I understand the problem.

One small change is needed to camick's solution, due to the table being scrollable:

Dimension dimensionParent = e.getComponent().getParent().getSize();

EDIT: sorry this does not work when you have already scrolled down.

i changed this code little bit so that the popup menu should apper mouse point

if (x + dimensionPopup.width > dimensionParent.width)

x = dimensionParent.width - (dimensionParent.width - x) - dimensionPopup.width ;

if (y + dimensionPopup.height > dimensionParent.height)

y = dimensionParent.height - (dimensionParent.height - y) - dimensionPopup.height;

it's work fine,

i am tring figure why the first menu item is selected

thanks

thanks camickr,

the workaround is not working for me,.

here the demo.

and the printf statement in the setSelected() method also not printing

import java.awt.Component;

import java.awt.Dimension;

import java.awt.event.MouseAdapter;

import java.awt.event.MouseEvent;

import javax.swing.JFrame;

import javax.swing.JMenuItem;

import javax.swing.JPanel;

import javax.swing.JPopupMenu;

import javax.swing.JSeparator;

import javax.swing.JTable;

import javax.swing.MenuSelectionManager;

import javax.swing.SwingUtilities;

public class PopupMenu extends JFrame

{

protected JMenuItem m_mniInsertRow;

protected JMenuItem m_mniInsertScrip;

protected JMenuItem m_mniDeleterRow;

protected JMenuItem m_mniDeleteExpiredScrip;

protected JMenuItem m_mniSetAlert;

public PopupMenu() {

final JPopupMenu popupMenu = new JPopupMenu()

{

public void setSelected(Component sel)

{

int index = getComponentIndex( sel );

System.out.println("index"+index);

getSelectionModel().setSelectedIndex(index);

final MenuElement me[] = new MenuElement[2];

me[0]=(MenuElement)this;

me[1]=getSubElements()[index];

System.out.println("element"+me);

SwingUtilities.invokeLater(new Runnable()

{

public void run()

{

MenuSelectionManager.defaultManager().setSelectedPath(me);

}

});

}

};

m_mniInsertRow = new JMenuItem("Insert a Row");

m_mniInsertScrip = new JMenuItem("Insert a Scrip");

m_mniDeleterRow = new JMenuItem("Delete a Row");

m_mniDeleteExpiredScrip = new JMenuItem("Delete a Expired Scrip");

m_mniSetAlert = new JMenuItem("Set Alert");

popupMenu.add(m_mniInsertRow);

popupMenu.add(m_mniInsertScrip);

popupMenu.addSeparator();

popupMenu.add(m_mniDeleterRow);

popupMenu.add(m_mniDeleteExpiredScrip);

popupMenu.add(new JSeparator());

popupMenu.add(m_mniSetAlert);

JPanel jp = new JPanel();

jp.setPreferredSize(new Dimension(400,400));

jp.addMouseListener(new MouseAdapter() {

public void mouseReleased(MouseEvent e) {

if (e.isPopupTrigger()) {

int x = e.getX();

int y = e.getY();

popupMenu.show(e.getComponent(), x, y);

}

}

});

getContentPane().add(jp);

pack();

setDefaultCloseOperation(EXIT_ON_CLOSE);

setVisible(true);

}

public static void main(String[] args)

{

new PopupMenu();

}

}

thanks

what i think is setSelected method is Overrided method?

and one more thing is throwing an exception java.lang.ArrayIndexOutOfBoundsException

i found out this is due to JSeparator() component.

but i have to do it dynamicaly.

thanks
