eclipse - How to auto refresh gui screen in java, after update taking place in a stored file? -


i have java swing application reads values components .text file. i'm trying update 1 of value , store in .text file , need refresh possibly in gui screen well. value modified in file gui not detect change without restart. have went through repaint(), re-validate() use of timers. can specify do? in advance.

a solution store of gui components in arraylist or other sort of list may prefer.

you read text file , add it's respective components list, , load list gui. when file edited, can loop through again , if component not exists in list can add in. if components in list don't correspond file can remove them list. after happens, can reload gui components in list.
