Struct ItemIterator 

pub struct ItemIterator<'a> { /* private fields */ }

Calculates some information that is later used to detect in which index the dragged item should be placed. ItemIterator::next should be called for each item in the list.

Implementations

impl<'a> ItemIterator<'a>

pub fn next( &mut self, ui: &mut Ui, id: Id, idx: usize, add_surrounding_space_automatically: bool, content: impl FnOnce(&mut Ui, Item<'_>) -> ItemResponse, )

Draw a dnd item. This should be called for each item in the list.

If add_surrounding_space_automatically is false, you need to call ItemIterator::space_before and ItemIterator::space_after manually. This is useful, e.g. to add a divider between items. Check the custom ui example.

pub fn space_before( &mut self, ui: &mut Ui, id: Id, content: impl FnOnce(&mut Ui, Vec2), )

Add some custom ui before the item.

pub fn space_after( &mut self, ui: &mut Ui, id: Id, content: impl FnOnce(&mut Ui, Vec2), )

Add some custom ui after the item.
