From 8f7579774c5372992d44dba9e7704eb80a511850 Mon Sep 17 00:00:00 2001 From: Elliot Lee Date: Tue, 12 Dec 2000 19:34:41 +0000 Subject: [PATCH] GMainContext useful in implementing some additional styles of main loop * gmain.c, gmain.h (g_main_context_new, g_main_context_destroy): GMainContext useful in implementing some additional styles of main loop usage. To do this, however, Joe Hacker needs to be able to create/destroy GMainContext's at will. This is just an export of existing functionality, rather than new functionality. They are listed in the "Low level functions for implementing custom main loops" section of the header file, to avoid confusing people. * gobject/Makefile.am: . You have to 'touch oldest-source-stamp' if you want to avoid having the Makefile constantly rebuild itself. . Fix marshaller generation rules to work with srcdir != builddir (there were issues with trying to run "./glib-genmarshal", etc.) --- ChangeLog | 11 ++++++ ChangeLog.pre-2-0 | 11 ++++++ ChangeLog.pre-2-10 | 11 ++++++ ChangeLog.pre-2-12 | 11 ++++++ ChangeLog.pre-2-2 | 11 ++++++ ChangeLog.pre-2-4 | 11 ++++++ ChangeLog.pre-2-6 | 11 ++++++ ChangeLog.pre-2-8 | 11 ++++++ glib/gmain.c | 111 ++++++++++++++++++++++++++++++---------------------- glib/gmain.h | 3 ++ gmain.c | 111 ++++++++++++++++++++++++++++++---------------------- gmain.h | 3 ++ gobject/ChangeLog | 8 ++++ gobject/Makefile.am | 25 ++++++------ 14 files changed, 246 insertions(+), 103 deletions(-) diff --git a/ChangeLog b/ChangeLog index 5b83137..aefd746 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,14 @@ +2000-12-12 Elliot Lee + + * gmain.c, gmain.h (g_main_context_new, g_main_context_destroy): + GMainContext useful in implementing some additional styles of + main loop usage.
