java swing jtable screen location of cell renderer component

I'm new to swing and I faced my first serious problem, here goes:

I have a JPanel with JTable and lots of checkboxes below the table. I'm trying to align the checkboxes below the table with checkbox located in the first table column. The problem is - this has to be done when model data changes.

Immediatly after the fireTableDataChanged() gets triggered in JTable there is no way to get the screen location of its custom cell renderer component (which in my case is JCheckBox). As far as I understand this happens because JTable gets redrawn asynchronously. Whenever I try to get the location the IllegalComponentStateException gets thrown.

Any ideas on this are highly appreciated.

This might help you to get screen location of row and column.

Rectangle rect= cartTable.getCellRect(row,column,true); //cartTable-Jtable object name int x=Double.valueOf(rect.getX()).intValue(); int y=Double.valueOf(rect.getY()).intValue();

You shouldn't do it manually. You should use the appropriate layoutManager. Check this link for the different Layouts:
