Struct egui_vulkano::Painter

pub struct Painter {
    pub pipeline: Arc<GraphicsPipeline>,
    pub sampler: Arc<Sampler>,
    /* private fields */
}

Contains everything needed to render the gui.

Fields

pipeline: Arc<GraphicsPipeline>

Graphics pipeline used to render the gui.

sampler: Arc<Sampler>

Texture sampler used to render the gui.

Implementations

impl Painter

pub fn new(
    device: Arc<Device>,
    queue: Arc<Queue>,
    subpass: Subpass
) -> Result<Self, PainterCreationError>

Pass in the vulkano Device, Queue and Subpass that you want to use to render the gui.

pub fn update_textures<P>(
    &mut self,
    textures_delta: TexturesDelta,
    builder: &mut AutoCommandBufferBuilder<PrimaryAutoCommandBuffer<P::Alloc>, P>
) -> Result<UpdateTexturesResult, UpdateTexturesError> where
    P: CommandPoolBuilderAlloc, 

Uploads all newly created and modified textures to the GPU. Has to be called before entering the first render pass.
If the return value is UpdateTexturesResult::Changed, a texture will be changed in this frame and you need to wait for the last frame to finish before submitting the command buffer for this frame.

pub fn draw<P>(
    &mut self,
    builder: &mut AutoCommandBufferBuilder<PrimaryAutoCommandBuffer<P::Alloc>, P>,
    window_size_points: [f32; 2],
    egui_ctx: &Context,
    clipped_shapes: Vec<ClippedShape>
) -> Result<(), DrawError> where
    P: CommandPoolBuilderAlloc, 

Advances to the next rendering subpass and uses the [ClippedShape]s from egui::FullOutput to draw the gui.
