.NET binding for the Nuklear immediate mode GUI https://github.com/vurtun/nuklear
NuklearSharp ( https://github.com/leafi/NuklearSharp ) was my original inspiration for this.
No original nuklear source files were modified. A project was created with some support code to build Nuklear.dll (x64) with all API functions exported and ready to be used from .NET
Updating should be as easy as updating the submodule and rebuilding the project.
Currently this binding is used in my game engine project, so i implement stuff as i need it. https://github.com/sbarisic/libTech
Contributions welcome.

The custom device class implements actual drawing functions, it has to inherit from at least NuklearDevice. NuklearDeviceTex allows you to specify your custom texture class which replaces the internal texture handle integers, just for convenience. You can return your own texture handle integers in NuklearDevice and handle textures manually.
Optionally it can implement the IFrameBuffered interface which calls the Render function only when the GUI actually changes. It it supposed to be rendered to a framebuffer which is in turn rendered to the screen every frame in RenderFinal
class Device : NuklearDeviceTex<Texture>, IFrameBuffered {
public override Texture CreateTexture(int W, int H, IntPtr Data) {
// Create a texture from raw image data
return null;
}
void IFrameBuffered.BeginBuffering() {
// Begin rendering to framebuffer
}
public override void SetBuffer(NkVertex[] VertexBuffer, ushort[] IndexBuffer) {
// Called once before Render, upload your vertex buffer and index buffer here
}
public override void Render(NkHandle Userdata, Texture Texture, NkRect ClipRect, uint Offset, uint Count) {
// Render to either framebuffer or screen
// If IFrameBuffered isn't implemented, it's called every frame, else only when the GUI actually changes
// Called multiple times per frame, uses the vertex and index buffer that has been sent to SetBuffer
}
void IFrameBuffered.EndBuffering() {
// End rendering to frame buffer
}
void IFrameBuffered.RenderFinal() {
// Called each frame, render to screen finally
}
}Sending events; just call these when you capture the events from your input API. It's irrelevant when they're called. They are internally queued and dispatched to Nuklear on every frame.
Device.OnMouseButton(Button, X, Y, Down)
Device.OnMouseMove(X, Y)
Device.OnScroll(X, Y)
Device.OnText(Text)
Device.OnKey(Key, Down)Using the GUI, note that the while loop represents an OnRender function in your renderer code. At the end of the Frame call, the actual rendering functions are dispatched.
NuklearAPI.Init(Device);
while (true) {
// Optional
NuklearAPI.SetDeltaTime(Dt);
NuklearAPI.Frame(() => {
NuklearAPI.Window("Test Window", 100, 100, 200, 200, Flags, () => {
NuklearAPI.LayoutRowDynamic(35);
if (NuklearAPI.ButtonLabel("Some Button"))
Console.WriteLine("You pressed Some Button!");
});
});
}- Demo application
- Higher level binding
- Support for multiple contexts, want to draw a GUI and some example on a 3D in-game screen at the same time?
