Hello all,

I'm stuck in my app right now. I'd like to be able to repopulate my table of contents (which is a SWT list) based on the selection of a folder from a combo box. I'm new to java/swt and gui programming all together for that matter. Please refer to my code below. Any help is most aprreciated, thank you in advance,
