imgui-glfw-rs: GLFW Input handling for ImGui

EXPERIMENTAL!

GLFW input handling for imgui

How to use

// Use the reexported glfw crate to avoid version conflicts.
use imgui_glfw_rs::glfw;
// Use the reexported imgui crate to avoid version conflicts.
use imgui_glfw_rs::imgui;

use imgui_glfw_rs::ImguiGLFW;
// ImGui uses { ... }

fn main() {
    // Initialize imgui and glfw and imgui renderer.
    // { ... }

    let mut imgui_glfw = ImguiGLFW::new(&mut imgui);

    while !window.should_close() {
        let ui = imgui_glfw.frame(&mut window, &mut imgui);

        // Draw your ui.
        // { ... }

        window.swap_buffers();

        // Handle imgui events
        glfw.poll_events();
        for (_, event) in glfw::flush_messages(&events) {
            imgui_glfw.handle_event(&mut imgui, &event);
        }
    }
}
