imgui-sdl2

SDL2 Input handling for imgui-rs

Integration guide

1. Construct it.

   let mut imgui_sdl2 = imgui_sdl2::ImguiSdl2::new(&mut imgui, &window);

2. At the top of your event handling loop, pass in the input events, and ignore the ones that imgui has captured.

   imgui_sdl2.handle_event(&mut imgui, &event);
   if imgui_sdl2.ignore_event(&event) { continue; }

3. Call prepare_frame before calling imgui.frame().

   imgui_sdl2.prepare_frame(imgui.io_mut(), &window, &event_pump.mouse_state());

4. Call prepare_render immediately before your UI rendering code.

   imgui_sdl2.prepare_render(&ui, &window);
