ImGuiSFML

A simple way to use ImGui with SFML.

Rendering is done using OpenGL2 backend available in DearImGui itself.

#include <ImGuiSFML/SFML.h>

#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>

#include <chrono>

int main(int argc, char* argv[])
{
	sf::RenderWindow sfWindow(sf::VideoMode(1024, 780), "Demo");

	// Create and initialize ImGui SFML
	ImGuiSFML mImguiHandler;
	mImguiHandler.Init(sfWindow);
	
	sf::Clock frameClock;
	while (sfWindow.isOpen())
	{
		// Start new frame
		mImguiHandler.OnFrameBegin();
		
		// Process SFML events
		sf::Event event;
		while (sfWindow.pollEvent(event))
		{
			// Forward events to ImGui
			mImguiHandler.OnEvent(event);
			// Close window: exit
			if (event.type == sf::Event::Closed)
				sfWindow.close();
		}
		using namespace std::chrono_literals;
		const sf::Time dt = frameClock.restart();
		std::chrono::milliseconds dtMs = dt.asMilliseconds() * 1ms;
		mImguiHandler.Update(dtMs);

		sfWindow.clear();

		// Render ImGui
		mImguiHandler.Draw(sfWindow);

		sfWindow.display();

		// Remove this when you have some actual code running and frame cannot be 0ms duration anymore
		std::this_thread::sleep_for(1ms);
	}

	return 0;
}
