What is the Vulkan equivalent of the GtkGLArea widget (GTK+)?

Question

Background: I want to write a CAD application. I want to implement all rendering with Vulkan. And I want to use GTK+.

I don't want a (visible) different window for the rendered image of the object.

So I researched and found the GtkGLArea widget, which seems to do what I want, but for OpenGL.

Is there an equivalent to GTKGLArea? If not, is there another way to implement what I'm thinking of?

Answer 1

There is a GdkWindow which I believe is behind many Gtk graphic types such as GtkWindow and GtkWidget and obtainable with gtk_*_get_window(). GdkWindow has gdk_window_create_vulkan_context(). With GdkVulkanContext you can get raw Vulkan types and theoretically should be able to render to with Vulkan.
