I am developing a custom search component. When clicked on the button(search image icon) inside the text field, a table is displayed. The code is in very nascent stage so lots of things is not there.
As of now, I am stuck because I am not able to navigate the table with the arrow keys. Neither am I able to move to the next text field with "tab" key, once I select a row in the table.
The objective of the component is to select a row from the table and then with the help of the supporting methods(yet to be written) values from other labels and text fields would be defaulted while defaulting 1 st column value in the text field it is attached to.
Would really appreciate your help. Thanks !!

do you meaning
use undecorated JDialog instead of JWindow, otherwise JTextComponets aren't editable
JDialog has better support for AlwaysOnTop and ModalityTypes (only hardcoded to the setAlwaysOnTop)
don't to recreate basic setting again and again, don't to recreate a popup windod, use lolac variable, remove all contents and add a new ony, define all setting for JDialog once time, see exception (The dialog is displayable.) in the case that popup is hidden and value in JTextField isn't empty
missed action for hide JDialog on ESC key event, hide JDialog, if is JFrame minimalized
missed moving with JDialog if JFrame is resized, moved over screen on another Point,
attach Document to the JTextField directly, not lost somwhere in to the JScrollPane definitions
your code missing a few good practicies, then everything is possible but not with this code (after my edit too)
search for JCalendar by Kay Toedter (best popup workaround as I saw for popup window)
only removed uselles methods, moved from- to, notice non_optimized_code, simple put to the recyclebin and wrote that again
