问题
I'd like to build a menu in ncurses that has section dividers.
My example list looks like this:
Aardvark
Apple
Bee
Cat
Kitten
Kalashnikov
Waffle
What I want is non-selectable dividers. Something like this:
(A) ----
Aardvark
Apple
(B) ----
Bee
(C) ----
Cat
(K) ----
Kitten
Kalashnikov
(W) ----
Waffle
Is there a built-in way to do this?
More specifically, I'm using this ruby gem: https://github.com/eclubb/ncurses-ruby I'd prefer an answer that was generic, but if it can be solved with Ruby awesomeness, that's cool too.
回答1:
Assuming you are talking about the ncurses menu library (as "built-in"), you can make a nonselectable item using set_item_opts.
