Struct kas::widget::MenuToggle

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

A menu entry which can be toggled

Methods

impl<M: 'static> MenuToggle<M>

pub fn new_on<T: Into<AccelString>, F>(f: F, label: T) -> Self where
    F: Fn(bool) -> M + 'static, 

Construct a togglable menu entry with a given label and closure

This is a shortcut for MenuToggle::new(label).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.

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

Set the initial state of the checkbox.

impl MenuToggle<VoidMsg>

pub fn new<T: Into<AccelString>>(label: T) -> Self

Construct a togglable menu entry with a given label

pub fn on_toggle<M, F>(self, f: F) -> MenuToggle<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.
