JTable in Linux

[Vijay Chandran]

Dear all,

I have created a swing utility which contains a JTable. Whenever i right click on the table cell a pop-up menu appears.This is working fine in MS-Windows.
When i do the same right click on the table cell in Linux enviroment. The pop-up menu is not appearing.

Kindly help me to sort out this problem. I'm doing the operation in an executable jar.

Can you give us a small sample of code that exhibits this behavior?
What version of Java are you using on both platforms?

jTableDetails.addMouseListener(new MouseAdapter()
{
public void mousePressed(MouseEvent evt)
{
int col_Sel =
jTableDetails.columnAtPoint(evt.getPoint());
int row_Sel = jTableDetails.rowAtPoint(evt.getPoint());
}
public void mouseReleased(MouseEvent evt)
{
selRow = returnRow();
selCol = returnColumn();
boolean isPointInside = false;
int sel_rowCnt = jTableDetails.getSelectedRowCount();
int sel_colCnt = jTableDetails.getSelectedColumnCount();
int col_Sel =
jTableDetails.columnAtPoint(evt.getPoint());
int row_Sel = jTableDetails.rowAtPoint(evt.getPoint());
for (int i = 0; i < sel_rowCnt; i++)
{
for (int j = 0; j < sel_colCnt; j++)
{
if (selRow + i == row_Sel && selCol + j
== col_Sel)
{
isPointInside = true;
break;
}
}
}
if (evt.isPopupTrigger())
{

menu.show(jTableDetails.getComponentAt(evt.getPoint()), evt.getX(),
evt.getY());
if (col_Sel >= 0 && row_Sel >= 0 &&
!isPointInside)
{
jTableDetails.changeSelection(row_Sel,
col_Sel, false, false);

jTableDetails.getComponentAt(evt.getPoint()).repaint();
}
}
}
public void mouseClicked(MouseEvent e)
{
if (jTableDetails.getSelectedColumn() != 0)
{
jTableDetails.setRowSelectionAllowed(false);
jTableDetails.setCellSelectionEnabled(true);
jTableDetails.repaint();
}
else
{
jTableDetails.setCellSelectionEnabled(false);
jTableDetails.setRowSelectionAllowed(true);
jTableDetails.repaint();
}
}
});
public int returnRow()
{
int selectRow = 0;
try
{
selectRow = jTableDetails.getSelectedRow();
}
catch (Exception e)
{
e.printStackTrace();
}
return selectRow;
}
public int returnColumn()
{
int selectCol = 0;
try
{
selectCol = jTableDetails.getSelectedColumn();
}
catch (Exception e)
{
e.printStackTrace();
}
return selectCol;
}
   

This is the code that triggers he right-click popupmenu and the menu contains some items like cut copy paste.
In both Windows and Linux i am using the same Java version j2sdk1.4.2_04
