Struct kas::widget::CheckBoxBare

pub struct CheckBoxBare<M: 'static> { /* fields omitted */ }

A bare checkbox (no label)

Methods

impl<M: 'static> CheckBoxBare<M>

pub fn new_on<F: Fn(bool) -> M + 'static>(f: F) -> Self

Construct a checkbox which calls f when toggled

This is a shortcut for CheckBoxBare::new().on_toggle(f).

The closure f is called with the new state of the checkbox when toggled, and the result of f is returned from the event handler.

impl CheckBoxBare<VoidMsg>

pub fn new() -> Self

Construct a checkbox

pub fn on_toggle<M, F>(self, f: F) -> CheckBoxBare<M> where
    F: Fn(bool) -> M + 'static, 

Set the event handler to be called on toggle.

The closure f is called with the new state of the checkbox when toggled, and the result of f is returned from the event handler.

impl<M: 'static> CheckBoxBare<M>

pub fn state(self, state: bool) -> Self

Set the initial state of the checkbox.
