Struct widgetry::tools::choose_something::ChooseSomething

pub struct ChooseSomething<A, T> {
    panel: Panel,
    cb: Option<Box<dyn FnOnce(T, &mut EventCtx<'_>, &mut A) -> Transition<A>>>,
}

Choose something from a menu, then feed the answer to a callback.

Fields

panel: Panel

cb: Option<Box<dyn FnOnce(T, &mut EventCtx<'_>, &mut A) -> Transition<A>>>

Implementations

impl<A: 'static, T: 'static> ChooseSomething<A, T>

pub fn new_state<I: Into<String>>(
    ctx: &mut EventCtx<'_>,
    query: I,
    choices: Vec<Choice<T>>,
    cb: Box<dyn FnOnce(T, &mut EventCtx<'_>, &mut A) -> Transition<A>>
) -> Box<dyn State<A>>

Trait Implementations

impl<A: 'static, T: 'static> State<A> for ChooseSomething<A, T>

fn event(&mut self, ctx: &mut EventCtx<'_>, app: &mut A) -> Transition<A>

Respond to a UI event, such as input or time passing.

fn draw_baselayer(&self) -> DrawBaselayer

Specifies what to draw before draw()

fn draw(&self, g: &mut GfxCtx<'_>, _: &A)

Draw

fn on_destroy(&mut self, _: &mut EventCtx<'_>, _: &mut A)

Before this state is popped or replaced, call this.

fn recreate(&mut self, _: &mut EventCtx<'_>, _: &mut A) -> Box<dyn State<A>>

Respond to Transition::Recreate by assuming state in the app has changed, but preserving the State-specific state appropriately.
