Struct AppearancePage 

pub struct AppearancePage<S> { /* private fields */ }

The Appearance page: a tab per scope, and the theme’s settings and the language picker over the open tab’s values. A change is given as it is made — a click, a choice, or the end of a drag — for the host to store; the page saves nothing.

The widgets install what they show, so a drag previews live. Once the host has stored a change, it installs the look in effect, which on a scope that does not win (a workgroup’s, under the device’s own) is not the one just chosen. Until the host calls reloaded, the page keeps showing the change rather than the values the host gives, which are still the ones from before it; a host that stores at once calls it right after.

Implementations

impl<S: Copy + PartialEq> AppearancePage<S>

pub fn new() -> AppearancePage<S>

A page that opens on the first enabled tab.

pub fn with_tab(self, scope: S) -> AppearancePage<S>

A page that opens on scope’s tab.

pub fn tab(&self) -> Option<S>

The open tab.

pub fn ui( &mut self, ui: &mut Ui, cx: &AppearanceCtx<'_, S>, notes: impl FnOnce(&mut Ui, S), ) -> Option<AppearanceChange<S>>

Render; the change the person made, if any. notes draws under the tabs, for the open scope: where its values come from, a way to drop its own.

pub fn reloaded(&mut self)

The host has its values again, a change stored or not: show them.

pub fn failed(&mut self, why: impl Into<String>)

The last change could not be stored, for why: say so, and show the host’s values again.
