Clear selection on FocusLost of Jtable.

Question

Hi
I have a jtable in which some columns are editable and some are non-editable. I want to clear the selections in jtbale when focus is lost from jtable.
But i cannot write the code table.clearSelection() in the focusLost() method of JTable since it will not be invoked when another component is clicked using mouse, when the table editing is started.
When another component is clicked when the table is in edit mode, the focusLost() of Jtable will not be invoked, but the focusLost() of that editor component will be triggered. So that table.clearSelection() will not work in this case.
Can anybody suggest a solution to this problem ? I have already added putClienProperty("terminateEditOnFocusLost", Boolean.TRUE) to stop cell editing when focus is lost. Is there any methods like table.putClientProperty("clearSelectionOnFocusLost", Boolean.TRUE); ?? Do i need to add focus listener to each editor components ? Please hep.
with thanks & regards

You can listen for all focus change events using the following code:
KeyboardFocusManager.getCurrentKeyboardFocusManager()
     .addPropertyChangeListener("focusOwner", new PropertyChangeListener()
     public void propertyChange(PropertyChangeEvent e)
          if (e.getNewValue() == null) return;
          Component c = (Component)e.getNewValue();
          System.out.println();
          System.out.println(c.getClass());
          System.out.println(c.getParent().getClass());
});When your table gains focus you can set a boolean variable to indicate this. When another component gains focus (whose parent isn't the table), then you clear the table selection and reset the boolean variable.
