Struct MainWindowWithRenderer

pub struct MainWindowWithRenderer { /* private fields */ }

This is a MainWindow plus a Renderer. It is the ultimate easy-imgui object. Instead of a literal MainWindow you can use any type that implements MainWindowRef.

Implementations

impl MainWindowWithRenderer

pub fn new(main_window: MainWindow) -> Self

Creates a new Renderer and attaches it to the given window.

pub fn with_builder(main_window: MainWindow, builder: &ContextBuilder) -> Self

Creates a new Renderer and attaches it to the given window.

The builder argument can be used to modify the inner ImGui context.

pub fn set_idle_time(&mut self, time: Duration)

Sets the time after which the UI will stop rendering, if there is no user input.

pub fn set_idle_frame_count(&mut self, frame_count: u32)

Sets the frame count after which the UI will stop rendering, if there is no user input.

Note that by default V-Sync is enabled, and that will affect the frame rate.

pub fn ping_user_input(&mut self)

Forces a rebuild of the UI.

By default the window will stop rendering the UI after a while without user input. Use this function to force a redraw because of some external factor.

pub fn renderer(&mut self) -> &mut Renderer

Gets a reference to the inner renderer.

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

Gets a reference to the ImGui context by the renderer.

Just like self.renderer().imgui()

pub fn main_window(&mut self) -> &mut MainWindow

Gets a reference to the inner window.

pub fn new_with_renderer(main_window: MainWindow, renderer: Renderer) -> Self

Attaches the given window and renderer together.

pub fn window_event( &mut self, app: &mut impl UiBuilder, event: &WindowEvent, flags: EventFlags, ) -> EventResult

The main event function. Corresponds to winit’s ApplicationHandler::window_event.

It returns EventResult. You can use it to break the main loop, or ignore it, as you see fit. It also informs of whether ImGui want the monopoly of the user input.

pub fn new_events(&mut self)

Corresponds to winit’s ApplicationHandler::new_events.

pub fn about_to_wait(&mut self)

Corresponds to winit’s ApplicationHandler::about_to_wait.
