pub fn set( &mut self, caller: Option<PickerCaller>, desc: Option<String>, content: Vec<String>, )

Trait Implementations

impl Content<String> for Picker

Implement a selectable content for this struct. This trait allows to navigate through a vector of element content_type. It implements: selected, content, push, style. selected returns an optional reference to the value.

fn selected(&self) -> Option<&String>

Returns a reference to the selected content.

fn content(&self) -> &Vec<String>

A reference to the content.

fn style(&self, index: usize, style: &Style) -> Style

Reverse the received effect if the index match the selected index.

fn push(&mut self, element: String)

Push a new element at the end of content

impl Default for Picker

fn default() -> Picker

Returns the “default value” for a type.

impl DrawMenu<String> for Picker

fn draw_menu(&self, f: &mut Frame<'_>, rect: &Rect, window: &ContentWindow)

where Self: Content<T>,

impl Selectable for Picker

Implement a selectable content for this struct. This trait allows to navigate through a vector of element content_type. It implements: is_empty, len, next, prev, set_index and selected_is_last.

fn is_empty(&self) -> bool

True if the content is empty.

fn len(&self) -> usize

The size of the content.

fn prev(&mut self)

Select the prev item.

fn next(&mut self)

Select the next item.

fn index(&self) -> usize

Returns the index of the selected item.

fn set_index(&mut self, index: usize)

Set the index to a new value if the value is below the length.

fn selected_is_last(&self) -> bool

true if the selected element is the last of content
