ListStore

Required methods

fn append<P: IsA<Object>>(&self, item: &P)

Appends item to self. item must be of type ListStore:item-type.

This function takes a ref on item.

Use ListStoreExt::splice to append multiple items at the same time efficiently.

Feature: v2_44

item

the new item

fn insert<P: IsA<Object>>(&self, position: u32, item: &P)

Inserts item into self at position. item must be of type ListStore:item-type or derived from it. position must be smaller than the length of the list, or equal to it to append.

This function takes a ref on item.

Use ListStoreExt::splice to insert multiple items at the same time efficiently.

Feature: v2_44

position

the position at which to insert the new item

item

the new item

fn remove(&self, position: u32)

Removes the item from self that is at position. position must be smaller than the current length of the list.

Use ListStoreExt::splice to remove multiple items at the same time efficiently.

Feature: v2_44

position

the position of the item that is to be removed

fn remove_all(&self)

Removes all items from self.

Feature: v2_44

fn splice(&self, position: u32, n_removals: u32, additions: &[Object])

Changes self by removing n_removals items and adding n_additions items to it. additions must contain n_additions items of type ListStore:item-type. None is not permitted.

This function is more efficient than ListStoreExt::insert and ListStoreExt::remove, because it only emits ListModel::items-changed once for the change.

This function takes a ref on each item in additions.

The parameters position and n_removals must be correct (ie: position + n_removals must be less than or equal to the length of the list at the time this function is called).

Feature: v2_44

position

the position at which to make the change

n_removals

the number of items to remove

additions

the items to add

n_additions

the number of items to add
