This is supported on crate feature stack_dst only.

As Theme, but without associated types

This trait is implemented automatically for all implementations of Theme. It is intended only for use where a less parameterised trait is required.

Required methods

fn config(&self) -> MaybeBoxed<'_, dyn Any>

Get current config

fn apply_config(&mut self, config: &dyn Any) -> TkAction

Apply/set the passed config

fn init(&mut self, shared: &mut SharedState<DS>)

Theme initialisation

See also Theme::init.

fn new_window(&self, dpi_factor: f32) -> StackDst<dyn Window>

Construct per-window storage

Uses a StackDst to avoid requiring an associated type.

See also Theme::new_window.

fn update_window(&self, window: &mut dyn Window, dpi_factor: f32)

Update a window created by Theme::new_window

See also Theme::update_window.

unsafe fn draw_handle(
    &self,
    draw: DrawIface<'_, DS>,
    window: &mut dyn Window
) -> StackDst<dyn DrawHandle>

Construct a DrawHandle object

Uses a StackDst to avoid requiring an associated type.

See also Theme::draw_handle.

Safety

All references passed into the method must outlive the returned object.

fn clear_color(&self) -> Rgba

Background colour

See also Theme::clear_color.
