Struct easy_imgui::SelectionBasicStorage

pub struct SelectionBasicStorage { /* private fields */ }

Simple multi-selection storage facility.

By default it stores the indices in a collection. Use the with_callback_id() function to do something different.

Implementations

impl SelectionBasicStorage

pub fn new() -> Self

Creates a new selection storage.

By default the index is the ID.

pub fn with_callback_id<'a>( &'a mut self, f: impl FnMut(usize) -> ImGuiID + 'a, ) -> SelectionBasicStorageWithCallback<'a>

Decorates this storage with a map function.

The callback maps an index into an ID. This allows to re-sort the list without messing with the selection.

pub fn set_preserve_order(&mut self, preserve_order: bool)

pub fn contains(&self, id: ImGuiID) -> bool

pub fn clear(&mut self)

pub fn set_item_selected(&mut self, id: ImGuiID, selected: bool)

pub fn swap(&mut self, other: &mut SelectionBasicStorage)

pub fn iter(&self) -> SelectionBasicStorageIter<'_>

Trait Implementations

impl Default for SelectionBasicStorage

fn default() -> Self

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a SelectionBasicStorage

type Item = u32

The type of the elements being iterated over.

type IntoIter = SelectionBasicStorageIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> SelectionBasicStorageIter<'a>

Creates an iterator from a value.
