[Libvisual-devel] VisParam API

[Dennis S. <sy...@yo...>]

I've thought out the VisParam API, any comments ?

The container that contains a set of parameters:
struct _VisParamContainer {
        VisList entries;

	VisEventQueue *eventqueue;
};

A parameter entry:
struct _VisParamEntry {
	VisParamContainer *parent;
        char *name;
        VisParamType type;
        int flags;

        union {
                char *string;
                int *integer;
                float *floating;
                /** @todo add a VisColor entry as well */
        } data;
};

API functions:
VisParamContainer *visual_param_container_new ();
int visual_param_container_destroy (VisParamContainer *paramcontainer);

VisParamEntry *visual_param_entry_new ();
int visual_param_entry_free (VisParamEntry *param);

/* On a entry set an event is being emitted */
int visual_param_entry_set (VisParamEntry *param, char *name,
VisParamType type, int flags, void *data);

int visual_param_container_add (VisParamContainer *paramcontainer,
VisParamEntry *param);
int visual_param_container_add_new (VisParamContainer *paramcontainer,
char *name, VisParamType type, int flags, void *data);
int visual_param_container_remove (VisParamContainer *paramcontainer,
char *name);
VisParamEntry *visual_param_container_find (VisParamContainer
*paramcontainer, char *name);



The pointer to the eventqueue is optionally NULL and in case of a
plugin is being set by the plugin handler.

Please comment.
