Struct kas::widget::MenuEntry

pub struct MenuEntry<M: Clone + Debug + 'static> { /* fields omitted */ }

A standard menu entry

Methods

impl<M: Clone + Debug + 'static> MenuEntry<M>

pub fn new<S: Into<AccelString>>(label: S, msg: M) -> Self

Construct a menu item with a given label and msg

The message msg is emitted on activation. Any type supporting Clone is valid, though it is recommended to use a simple Copy type (e.g. an enum).

pub fn set_msg(&mut self, msg: M)

Replace the message value
