Struct kas_widgets::CheckBox

pub struct CheckBox { /* private fields */ }

A bare check box (no label)

See also CheckButton which includes a label.

Implementations

impl CheckBox

pub fn new() -> Self

Construct a check box

pub fn on_toggle<F>(self, f: F) -> CheckBoxwhere
    F: Fn(&mut EventMgr<'_>, bool) + 'static,

Set event handler f

When the check box is set or unset, the closure f is called.

pub fn new_on<F>(f: F) -> Selfwhere
    F: Fn(&mut EventMgr<'_>, bool) + 'static,

Construct a check box with event handler f

When the check box is set or unset, the closure f is called.

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

Set the initial state of the check box.

pub fn with_editable(self, editable: bool) -> Self

Set whether this widget is editable (inline)

pub fn is_editable(&self) -> bool

Get whether this widget is editable

pub fn set_editable(&mut self, editable: bool)

Set whether this widget is editable
