pub struct MultiTheme<DS> { /* private fields */ }

Run-time switching support for pre-loaded themes

Implementations

impl<DS> MultiTheme<DS>

pub fn new() -> MultiTheme<DS>

Construct an empty MultiTheme

At least one theme must be added before the UI starts..

pub fn add<S: ToString, T>(&mut self, name: S, theme: T) -> usize

where DS: DrawSharedImpl, T: ThemeDst<DS> + 'static,

Add a theme

Returns the index of the new theme.

pub fn set_active(&mut self, index: usize)

Set the active theme

If this is not called, then the first theme added will be active.

An invalid index will cause the UI to panic on start.
