GO_COLOR_GROUP_HISTORY_SIZE

#define GO_COLOR_GROUP_HISTORY_SIZE 8


GOColorGroup

typedef struct _GOColorGroup GOColorGroup;


GO_TYPE_COLOR_GROUP

#define GO_TYPE_COLOR_GROUP     (go_color_group_get_type ())


GO_COLOR_GROUP()

#define GO_COLOR_GROUP(obj)     (G_TYPE_CHECK_INSTANCE_CAST ((obj), GO_TYPE_COLOR_GROUP, GOColorGroup))

obj :


GO_IS_COLOR_GROUP()

#define GO_IS_COLOR_GROUP(obj)  (G_TYPE_CHECK_INSTANCE_TYPE ((obj), GO_TYPE_COLOR_GROUP))

obj :


go_color_group_get_type ()

GType               go_color_group_get_type             (void);

Returns :


go_color_group_find ()

GOColorGroup *      go_color_group_find                 (char const *name,
                                                         gpointer context);

No reference is added if it is found.

name :

target name

context :

an arbitrary id to identify what context to search in

Returns :

Look up the name/context specific color-group. NULL if it is not found.

go_color_group_fetch ()

GOColorGroup *      go_color_group_fetch                (char const *name,
                                                         gpointer context);

if name is NULL or a name not currently in use by another group then a new group is created and returned. If name was NULL then the new group is given a unique name prefixed by "__cg_autogen_name__" (thereby insuring namespace separation). If name was already used by a group then the reference count is incremented and a pointer to the group is returned.

name :

target name

context :

identifying context

Returns :

A GOColorGroup

go_color_group_add_color ()

void                go_color_group_add_color            (GOColorGroup *cg,
                                                         GOColor c);

Potentially slide the history to add the new colour. If it was already in the history reorder.

cg :

GOColorGroup

c :

the color
