Detailed Description

Callbacks to receive media tree events.

Field Documentation

on_children_added

void(* vlc_media_tree_callbacks::on_children_added) (vlc_media_tree_t *tree, input_item_node_t *node, input_item_node_t *const children[], size_t count, void *userdata)

Called when children has been added to a node.

The children may themselves contain children, which will not be notified separately.

Parameters

playlist	the playlist
node	the node having children added
children	the children added
count	the number of children added
userdata	userdata provided to AddListener()

on_children_removed

void(* vlc_media_tree_callbacks::on_children_removed) (vlc_media_tree_t *tree, input_item_node_t *node, input_item_node_t *const children[], size_t count, void *userdata)

Called when children has been removed from a node.

Parameters

playlist	the playlist
node	the node having children removed
children	the children removed
count	the number of children removed
userdata	userdata provided to AddListener()

on_children_reset

void(* vlc_media_tree_callbacks::on_children_reset) (vlc_media_tree_t *tree, input_item_node_t *node, void *userdata)

Called when the whole content of a subtree has changed.

Parameters

playlist	the playlist
node	the node having its children reset (may be root)
userdata	userdata provided to AddListener()

Referenced by test_media_tree_callbacks(), and test_media_tree_callbacks_on_add_listener().

on_preparse_end

void(* vlc_media_tree_callbacks::on_preparse_end) (vlc_media_tree_t *tree, input_item_node_t *node, int status, void *userdata)

Called when the preparsing of a node is complete.

Parameters

tree	the media tree
node	the node being parsed
status	the reason for the preparsing termination
userdata	userdata provided to AddListener()
