pub fn set_platform_accesskit(ctx: &Context, possible: bool)Expand description
Tell ui.wait {for: "idle"} whether the app has work of its own pending (background jobs,
a save in flight). Cheap: call it every frame.
Whether a platform AccessKit adapter (a screen reader) can turn AccessKit on for ctx
(true by default). With false (a context with no window, or a build without the adapter)
devtools switches AccessKit off again once it has answered the requests that needed the tree.
With true AccessKit stays on once a request turned it on: egui does not say whether a screen
reader turned it on meanwhile, and turning it off under one would leave it a stale tree.
