Expand description
Data that is passed to AppCreator
that can be used to setup and initialize your app.
Fields§
§egui_ctx: Context
The egui Context.
You can use this to customize the look of egui, e.g to call egui::Context::set_fonts
,
egui::Context::set_visuals
etc.
integration_info: IntegrationInfo
Information about the surrounding environment.
storage: Option<&'s dyn Storage>
You can use the storage to restore app state(requires the “persistence” feature).
gl: Option<Arc<Context>>
The glow::Context
allows you to initialize OpenGL resources (e.g. shaders) that
you might want to use later from a egui::PaintCallback
.
Only available when compiling with the glow
feature and using Renderer::Glow
.
get_proc_address: Option<&'s dyn Fn(&CStr) -> *const c_void>
The get_proc_address
wrapper of underlying GL context
wgpu_render_state: Option<RenderState>
The underlying WGPU render state.
Only available when compiling with the wgpu
feature and using Renderer::Wgpu
.
Can be used to manage GPU resources for custom rendering with WGPU using egui::PaintCallback
s.
