I'd really like to use Dialog and BASH if I can, however.
I have two questions concerning dialog:
Firstly, how do I get two widgets operating on the same screen? Is it even possible? I'd like to have a menu on the left-hand side containing a list of items with a running total on the right-hand side.
Secondly, where does the data from the menu go? How do I assign it to a variable that would affect the running totals on the right hand side? Reading the man pages for Dialog, output from a menu goes to something called stderr. I would need to add the dollar value of each selected item, have that value listed in the "Running total" widget on the right-hand side, and then possibly save everything to a file.
Am I better trying to do this using only BASH? Should I take a look at python-tcl/tk?
