Display JDialog below caret position

I would like to display JDialog below the current caret position in JTextArea in my program. I tried using, modelToView() to get the caret position but when i use the setLocation() method of the JDialog in this way, I am unable to get the desired location.

Rectangle r=jTextArea.modelToView(jTextArea.getCaretPosition());
jDialog.setLocation(r.x,r.y+jTextArea.getFontMetrics(jTextArea.getFont()).getHeight());

Also, could any one tell me why this snippet is not working in the desired way?

The rectangle is likely relative to the parent component. You need to translate the location to the screen

SwingUtilities.convertPointToScreen(r.getLocation(), jTextArea);
jDialog.setLocation(pos.x,pos.y+jTextArea.getFontMetrics(jTextArea.getFont()).getHeight());

I've not tried this, but I think...

jDialog.setLocation(pos.x,pos.y+r.height);

Might be cleaner...?
