Struct easy_imgui_renderer::Renderer

pub struct Renderer { /* private fields */ }

The main Renderer type.

Implementations

impl Renderer

pub fn new(gl: GlContext) -> Result<Renderer>

Creates a new renderer object.

You need to provide the OpenGL context yourself.

pub fn gl_context(&self) -> &GlContext

Gets a reference to the OpenGL context.

pub fn set_background_color(&mut self, color: Option<Color>)

Sets the default background color.

The set color will be used for glClear(GL_COLOR_BUFFER_BIT). Set to None to avoid this, and use easy_imgui::UiBuilder::pre_render to do whatever clearing you need, if anything.

pub fn background_color(&self) -> Option<Color>

Gets the background color.

pub fn imgui(&mut self) -> &mut Context

Gets the stored Dear ImGui context.

pub fn set_size(&mut self, size: Vector2, scale: f32)

Sets the UI size, in logical units, and the scale factor.

pub fn size(&mut self) -> Vector2

Gets the UI size, in logical units.

pub fn do_frame<A: UiBuilder>(&mut self, app: &mut A)

Builds and renders a UI frame, using the app easy_imgui::UiBuilder.

pub fn map_tex(ntex: Texture) -> TextureId

Maps an OpenGL texture to an ImGui texture.

pub fn unmap_tex(tex: TextureId) -> Option<Texture>

Gets an OpenGL texture from an ImGui texture.
