From 2982de6993e6d9944f2215d7cb9b558b465a0c99 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Thu, 27 Jul 2006 22:10:27 +0200 Subject: kconfig/menuconfig: lxdialog is now built-in lxdialog was previously called as an external program causing screen to flicker when used. With this patch lxdialog is now built-in. It is loosly based om previous work by: Petr Baudis Following is a list of changes: o Moved build of dialog routings to kconfig Makefile o menubox + checklist uses a new item list to hold all menu items o in util.c implmented helper function to deal with item list o menubox now uses parameters to save scroll state (avoids temp file) o textbox now get text to be displayed as parameter and not a file o make sure to properly delete subwin's before main windows o killed unused files: lxdialog.c msgbox.c o modified return value for ESC to match direct calling o in a few places the code has been adjusted to 80 char wide o in textbox a small refactoring was made to make code remotely readable o in mconf removed all unused stuff (functions/variables) Following is a list of know short comings: a) pressing ESC twice will be interpreted as two ESC presses b) resize does not work. menuconfig needs to be restarted to be adjusted Signed-off-by: Sam Ravnborg --- scripts/kconfig/lxdialog/Makefile | 21 --- scripts/kconfig/lxdialog/checklist.c | 136 +++++++--------- scripts/kconfig/lxdialog/dialog.h | 52 +++++- scripts/kconfig/lxdialog/inputbox.c | 2 +- scripts/kconfig/lxdialog/lxdialog.c | 204 ------------------------ scripts/kconfig/lxdialog/menubox.c | 95 +++++------ scripts/kconfig/lxdialog/msgbox.c | 72 --------- scripts/kconfig/lxdialog/textbox.c | 298 ++++++++--------------------------- scripts/kconfig/lxdialog/util.c | 134 +++++++++++++++- scripts/kconfig/lxdialog/yesno.c | 2 +- 10 files changed, 340 insertions(+), 676 deletions(-) delete mode 100644 scripts/kconfig/lxdialog/Makefile delete mode 100644 scripts/kconfig/lxdialog/lxdialog.c delete mode 100644 scripts/kconfig/lxdialog/msgbox.c (limited to 'scripts/kconfig/lxdialog') diff --git a/scripts/kconfig/lxdialog/Makefile b/scripts/kconfig/lxdialog/Makefile deleted file mode 100644 index a8b02632624..00000000000 --- a/scripts/kconfig/lxdialog/Makefile +++ /dev/null @@ -1,21 +0,0 @@ -# Makefile to build lxdialog package -# - -check-lxdialog := $(srctree)/$(src)/check-lxdialog.sh - -# Use reursively expanded variables so we do not call gcc unless -# we really need to do so.
