From b57429d0820250b6329535bf5a39d60305c79efb Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Tue, 24 Aug 2010 06:30:46 +0000 Subject: [PATCH] Create a checklist and call one of the *printw() functions from the selected() callback. When the dialog first appears, you will not see the printed statement on the dialog, if you move down one, you will, move up again and it now appears. I am assuming that you call a *printw() function on a line in the dialog box of course. The fix, from the pr: This is a hack at best, I looked at the redraw code in dialog_checklist() and took the minimal amount of it out to do a simple "refresh" right after the items are drawn. This doesn't hurt anything and makes the library work like it should. There is probably a better way however =).
