Struct DefaultDelegate 

pub struct DefaultDelegate {
    pub show_description: bool,
    pub styles: DefaultItemStyles,
    pub update_func: Option<Box<dyn Fn(&dyn Msg, &Model) -> Cmd + Send + Sync>>,
    pub short_help_func: Option<Box<dyn Fn() -> Vec<Binding> + Send + Sync>>,
    pub full_help_func: Option<Box<dyn Fn() -> Vec<Vec<Binding>> + Send + Sync>>,
    /* private fields */
}

DefaultDelegate is a standard delegate designed to work in lists. It’s styled by DefaultItemStyles, which can be customized as you like.

The description line can be hidden by setting show_description to false, which renders the list as single-line-items. The spacing between items can be set with the set_spacing method.

Fields

show_description: bool

Whether to show the description line.

styles: DefaultItemStyles

The styles for the delegate.

update_func: Option<Box<dyn Fn(&dyn Msg, &Model) -> Cmd + Send + Sync>>

An optional update function called on item updates.

short_help_func: Option<Box<dyn Fn() -> Vec<Binding> + Send + Sync>>

An optional short help function.

full_help_func: Option<Box<dyn Fn() -> Vec<Vec<Binding>> + Send + Sync>>

An optional full help function.

Implementations

impl DefaultDelegate

pub fn set_height(&mut self, i: usize)

SetHeight sets delegate’s preferred height.

pub fn height(&self) -> usize

Height returns the delegate’s preferred height. This has effect only if ShowDescription is true, otherwise height is always 1.

pub fn set_spacing(&mut self, i: usize)

SetSpacing sets the delegate’s spacing.

pub fn spacing(&self) -> usize

Spacing returns the delegate’s spacing.

pub fn render(&self, m: &Model, index: usize, item: &dyn Item) -> String

Render prints an item.

Trait Implementations

impl ItemDelegate for DefaultDelegate

fn render(&self, m: &Model, index: usize, item: &dyn Item) -> String

Render renders the item’s view.

fn height(&self) -> usize

Height is the height of the list item.

fn spacing(&self) -> usize

Spacing is the size of the horizontal gap between list items in cells.

fn update(&self, msg: &dyn Msg, m: &Model) -> Cmd

Update is the update loop for items. All messages in the list’s update loop will pass through here except when the user is setting a filter. Use this method to perform item-level updates appropriate to this delegate.

fn short_help(&self) -> Vec<Binding>

ShortHelp returns bindings for the short help view, if the delegate implements the help keymap interface.

fn full_help(&self) -> Vec<Vec<Binding>>

FullHelp returns bindings for the full help view, if the delegate implements the help keymap interface.
