comparison kconfig/lxdialog/dialog.h @ 10:4d21d59f3206

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add menuconfig, plus some basic Config info, lots of which is just future plans for toysh. Nothing's currently _using_ this config info, but at least it's being generated now.

35 * Colors in ncurses 1.9.9e do not work properly since foreground and
36 * background colors are OR'd rather than separately masked. This version
37 * of dialog was hacked to work with ncurses 1.9.9e, making it incompatible
38 * with standard curses. The simplest fix (to make this work with standard
39 * curses) uses the wbkgdset() function, not used in the original hack.
40 * Turn it off if we're building with 1.9.9e, since it just confuses things.
