From 1d79e173bb3f0def5cdd84b3f574becaaa203b98 Mon Sep 17 00:00:00 2001 From: Emmanuele Bassi Date: Thu, 19 Feb 2009 12:02:42 +0000 Subject: [PATCH] [cogl] Provide GTypes for COGL types COGL types should be registered inside the GType system, for bindings and type checking inside properties and signals. CoglHandle is a boxed type with a ref+unref semantics; slightly evil from a bindings perspective (we cannot associate custom data to it), but better than nothing. The rest of the exposed types are enumerations or bitmasks. --- cogl-types.h | 21 +++++- common/cogl-util.c | 175 +++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 194 insertions(+), 2 deletions(-) diff --git a/cogl-types.h b/cogl-types.h index b9454b33c..c52e0c9d6 100644 --- a/cogl-types.h +++ b/cogl-types.h @@ -24,7 +24,7 @@ #ifndef __COGL_TYPES_H__ #define __COGL_TYPES_H__ -#include +#include G_BEGIN_DECLS @@ -51,6 +51,12 @@ typedef gpointer CoglHandle;
