Struct iced_native::widget::checkbox::Checkbox

pub struct Checkbox<Message, Renderer: Renderer + Renderer> { /* fields omitted */ }

A box that can be checked.

Example

pub enum Message {
    CheckboxToggled(bool),
}

let is_checked = true;

Checkbox::new(is_checked, "Toggle me!", Message::CheckboxToggled);

Methods

impl<Message, Renderer: Renderer + Renderer> Checkbox<Message, Renderer>

pub fn new<F>(is_checked: bool, label: impl Into<String>, f: F) -> Self where
    F: 'static + Fn(bool) -> Message, 

Creates a new Checkbox.

It expects:

• a boolean describing whether the Checkbox is checked or not
• the label of the Checkbox
• a function that will be called when the Checkbox is toggled. It will receive the new state of the Checkbox and must produce a Message.

pub fn size(self, size: u16) -> Self

Sets the size of the Checkbox.

pub fn width(self, width: Length) -> Self

Sets the width of the Checkbox.

pub fn spacing(self, spacing: u16) -> Self

Sets the spacing between the Checkbox and the text.

pub fn text_size(self, text_size: u16) -> Self

Sets the text size of the Checkbox.

pub fn font(self, font: Renderer::Font) -> Self

Sets the Font of the text of the Checkbox.

pub fn style(self, style: impl Into<Renderer::Style>) -> Self

Sets the style of the Checkbox.
