Using Vulkan with SFML?

Im currently using GLFW for window creation and user input. GLFW simply allows us to say:

glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);

To tell GLFW were not working with OpenGL. It even provides function like

glfwCreateWindowSurface(...)

To automate window surface creation for different platforms.

Is there any way I can do something similar with SFML? I could not find any information about it on their website, so i assume the answer is no. But maybe there is some kind of hack, or is this not advised?

Vulkan is supported in the next minor release; SFML 2.6.0.

The new sf::WindowBase class, serves as the base class for all Windows. It provides a simple interface for manipulating the window: move, resize, show/hide, control mouse cursor, etc. It also provides event handling through its pollEvent() and waitEvent() functions.

sf::Window still serves as a target for OpenGL rendering, but it now inherits the above functionality from sf::WindowBase. This design choice was done, so as to not break existing code: see the full discussion for info.

The new sf::WindowBase does not create an OpenGL context by default. Instead it provides a public member function createVulkanSurface with the following definition.

////////////////////////////////////////////////////////////
/// \brief Create a Vulkan rendering surface
///
/// \param instance  Vulkan instance
/// \param surface   Created surface
/// \param allocator Allocator to use
///
/// \return True if surface creation was successful, false otherwise
///
////////////////////////////////////////////////////////////
bool createVulkanSurface(const VkInstance& instance, VkSurfaceKHR& surface, const VkAllocationCallbacks* allocator = 0);

A demonstration of usage (some 2.600 lines of code), can be found under examples in the SFML respiratory.

This is not yet integrated into SFML, but there's an open pull request adding/discussing this feature.
