From e4819b66649d4963a0661cba603c2967b02a6b80 Mon Sep 17 00:00:00 2001 From: Marijn van Vliet Date: Thu, 15 Oct 2009 15:01:55 +0000 Subject: [PATCH] * Changing styles no longer affects existing windows * glk_style_hint_clear() now works as intended * Support for changing stylehints on textgrids There are now four sets of tags stored inside two style_sets: default->text_grid default->text_buffer current->text_grid current->text_buffer The default styles get loaded from CSS (hardcoded if not present in CSS) The current styles get changed all the time and copied to a new window upon creation. git-svn-id: http://lassie.dyndns-server.com/svn/gargoyle-gtk@144 ddfedd41-794f-dd11-ae45-00112f111e67 --- libchimara/chimara-glk-private.h | 6 +- libchimara/chimara-glk.c | 3 +- libchimara/strio.c | 4 +- libchimara/style.c | 373 +++++++++++++++++++++++++------ libchimara/style.h | 20 ++ libchimara/window.c | 6 +- tests/style.css | 21 +- 7 files changed, 344 insertions(+), 89 deletions(-) diff --git a/libchimara/chimara-glk-private.h b/libchimara/chimara-glk-private.h index 4a274fb..5ea1e54 100644 --- a/libchimara/chimara-glk-private.h +++ b/libchimara/chimara-glk-private.h @@ -5,6 +5,7 @@ #include #include #include "glk.h" +#include "style.h" #include "gi_blorb.h" #include "gi_dispa.h" #include "chimara-glk.h" @@ -30,8 +31,9 @@ struct _ChimaraGlkPrivate { guint spacing;
