Struct ClickAction

Source

pub struct ClickAction<A> { /* private fields */ }

Expand description

Executable UI-thread callback for one click-like activation.

§Examples

use ailloli_ui_core::ElementId;
use ailloli_ui_runtime::app::RuntimeHandle;
use ailloli_ui_runtime::input::{ClickAction, EventCtx};
let runtime = RuntimeHandle::<u8>::new();
let mut ctx = EventCtx::new(runtime.clone(), ElementId(1));
ClickAction::handler(|ctx| ctx.dispatch(7)).run(&mut ctx);
assert_eq!(runtime.take_actions(), vec![7]);

Implementations§

Source §

impl<A> ClickAction<A>

Provides the operations defined for ClickAction<A>.

Source

pub fn handler(handler: impl Fn(&mut EventCtx<A>) + 'static) -> Self

Wraps a UI-thread event-context callback.

The callback is retained by Rc; captured resources live until every action clone/internal reference is dropped. Callback panics propagate.

§Examples

use ailloli_ui_core::ElementId;
use ailloli_ui_runtime::app::RuntimeHandle;
use ailloli_ui_runtime::input::{ClickAction, EventCtx};
let runtime = RuntimeHandle::<&'static str>::new();
let mut ctx = EventCtx::new(runtime.clone(), ElementId(1));
let action = ClickAction::handler(|ctx| ctx.dispatch("open"));
action.run(&mut ctx);
assert_eq!(runtime.take_actions(), vec!["open"]);

Source

pub fn run(&self, ctx: &mut EventCtx<A>)

Runs the stored callback synchronously with ctx.

§Examples

use ailloli_ui_core::ElementId;
use ailloli_ui_runtime::app::RuntimeHandle;
use ailloli_ui_runtime::input::{ClickAction, EventCtx};
let runtime = RuntimeHandle::<i32>::new();
let mut ctx = EventCtx::new(runtime.clone(), ElementId(9));
ClickAction::handler(|ctx| ctx.dispatch(3)).run(&mut ctx);
assert_eq!(runtime.take_actions(), vec![3]);
