Struct nannou::ui::prelude::widget::list_select::ListSelect [−][src]
pub struct ListSelect<M, D, S> { /* fields omitted */ }
A wrapper around the List
widget that handles single and multiple selection logic.
Implementations
impl ListSelect<Single, Down, Dynamic>
[src]
pub fn single(num_items: usize) -> ListSelect<Single, Down, Dynamic>
[src]
Construct a new ListSelect, allowing one selected item at a time.
impl ListSelect<Multiple, Down, Dynamic>
[src]
pub fn multiple(num_items: usize) -> ListSelect<Multiple, Down, Dynamic>
[src]
Construct a new ListSelect, allowing multiple selected items.
impl<M, D, S> ListSelect<M, D, S> where
M: Mode,
S: ItemSize,
D: Direction,
[src]
M: Mode,
S: ItemSize,
D: Direction,
pub fn flow_down(self) -> ListSelect<M, Down, S>
[src]
Flows items from top to bottom.
pub fn flow_right(self) -> ListSelect<M, Right, S>
[src]
Flows items from left to right.
pub fn flow_left(self) -> ListSelect<M, Left, S>
[src]
Flows items from right to left.
pub fn flow_up(self) -> ListSelect<M, Up, S>
[src]
Flows items from bottom to top.
pub fn item_size(self, length: f64) -> ListSelect<M, D, Fixed>
[src]
Specify a fixed item size, where size is a Scalar
in the direction that the List
is
flowing. When a List
is constructed with this method, all items will have a fixed, equal
length.
impl<M> ListSelect<M, Down, Dynamic>
[src]
pub fn new(num_items: usize, mode: M) -> ListSelect<M, Down, Dynamic> where
M: Mode,
[src]
M: Mode,
Begin building a new ListSelect
with the given mode.
This method is only useful when using a custom Mode
, otherwise ListSelect::single
or
ListSelect::multiple
will probably be more suitable.
impl<M, D, S> ListSelect<M, D, S>
[src]
pub fn scrollbar_next_to(self) -> ListSelect<M, D, S>
[src]
Specifies that the List
should be scrollable and should provide a Scrollbar
to the
right of the items.
pub fn scrollbar_on_top(self) -> ListSelect<M, D, S>
[src]
Specifies that the List
should be scrollable and should provide a Scrollbar
that hovers
above the right edge of the items and automatically hides when the user is not scrolling.
pub fn scrollbar_thickness(self, w: f64) -> ListSelect<M, D, S>
[src]
The width of the Scrollbar
.
pub fn scrollbar_color(self, color: Color) -> ListSelect<M, D, S>
[src]
The color of the Scrollbar
.
impl<M, D> ListSelect<M, D, Fixed>
[src]
pub fn instantiate_all_items(self) -> ListSelect<M, D, Fixed>
[src]
Indicates that an Item
should be instatiated for every element in the list, regardless of
whether or not the Item
would be visible.
This is the default (and only) behaviour for List
s with dynamic item sizes. This is
because a List
cannot know the total length of its combined items in advanced when each
item is dynamically sized and their size is not given until they are set.
Note: This may cause significantly heavier CPU load for lists containing many items (100+). We only recommend using this when absolutely necessary as large lists may cause unnecessary bloating within the widget graph, and in turn result in greater traversal times.
pub fn instantiate_only_visible_items(self) -> ListSelect<M, D, Fixed>
[src]
Indicates that only Item
s that are visible should be instantiated. This ensures that we
avoid bloating the widget graph with unnecessary nodes and in turn keep traversal times to
a minimum.
This is the default behaviour for ListSelect
s with fixed item sizes.
