countdown timers in multilist

[rvac...@gmail.com]

I have uploaded a project that shows multiple countdown timers in a Multilist. except that I am not able to render the list as I wish to. In the multilist I wish to utilise the multiple lines to display different items. (e.g. The countdown clock should be visible at Line1 (where currently "multibutton" is appearing" and the item1, item2 which is actually the title to appear in another line (line2 or line3 etc).

 

I am new to java and got this code fragment online and modified it a bit. Pl suggest if I am being on the right track and how to render the clock in the Multilist using hashtables.

 

The to-do video tutorial says I can add the elements in a hashtable and the table in a vector and set the list model to the vector. the sitation here is bit different because I may be adding timers continuously. how should I approach this problem.

 

Any changes in the code improving its efficiency/elegance are welcome and so are snippets or suggestions.

 

thanks./

I am unable to upload the project so heres the code.

My bad ..... in the OP correct the following....

" (e.g. The countdown clock should be visible at Line1 (where currently "multibutton" is appearing" >> this should be>> where "Entry1" is appearing >> and the item1, item2 which is actually the title to appear in another line (line2 or line3 etc). "

[Shai Almog]

So is this resolved?
