Struct kas_widgets::RadioButton

pub struct RadioButton { /* private fields */ }

A radio button with label

See also RadioBox which excludes the label.

Implementations

impl RadioButton

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

Construct a radio button with a given label and group

RadioButton labels are optional; if no label is desired, use an empty string or use RadioBox instead.

All instances of RadioBox and RadioButton constructed over the same group will be considered part of a single group.

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

Set event handler f

When the radio button is selected, the closure f is called.

No handler is called on deselection.

pub fn new_on<T: Into<AccelString>, F>(label: T, group: RadioGroup, f: F) -> Selfwhere
    F: Fn(&mut EventMgr<'_>) + 'static,

Construct a radio button with given label, group and event handler f

RadioButton labels are optional; if no label is desired, use an empty string.

All instances of RadioBox and RadioButton constructed over the same group will be considered part of a single group.

When the radio button is selected, the closure f is called.

No handler is called on deselection.

pub fn new_msg<S, M: Clone>(label: S, group: RadioGroup, msg: M) -> Selfwhere
    S: Into<AccelString>,
    M: Clone + Debug + 'static,

Construct a radio button with given label, group and payload msg

RadioButton labels are optional; if no label is desired, use an empty string.

All instances of RadioBox and RadioButton constructed over the same group will be considered part of a single group.

When the radio button is selected, a clone of msg is returned to the parent widget via EventMgr::push_msg.

No handler is called on deselection.

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

Set the initial state of the radio button.

pub fn select(&mut self, mgr: &mut EventMgr<'_>) -> bool

Select this radio box from the group

This radio box will be set true while all others from the group will be set false. Returns true if newly selected, false if already selected.

This does not call the event handler set by Self::on_select or Self::new_on.

pub fn unset_all(&self, mgr: &mut EventMgr<'_>)

Unset all radio boxes in the group

Note: state will not update until the next draw.
