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.

Feature gated: this is only available with feature stack_dst.

Required methods

fn init(&mut self, draw: &mut D)[src]

Theme initialisation

See also Theme::init.

fn new_window(
    &self,
    draw: &mut D::Draw,
    dpi_factor: f32
) -> StackDst<dyn WindowDst>[src]

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 WindowDst, dpi_factor: f32)[src]

Update a window created by Theme::new_window

See also Theme::update_window.

unsafe fn draw_handle(
    &self,
    draw: &mut D::Draw,
    window: &mut dyn WindowDst,
    rect: Rect
) -> StackDst<dyn DrawHandle>[src]

Construct a DrawHandle object

Uses a StackDst to avoid requiring an associated type.

See also Theme::draw_handle.

This function is unsafe because the returned object requires a lifetime bound not exceeding that of all three pointers passed in.

fn clear_color(&self) -> Colour[src]

Background colour

See also Theme::clear_color.
