My Code as follows, thats just use official demo calculator:

#define NK_IMPLEMENTATION
#define NK_INCLUDE_DEFAULT_FONT
#define NK_INCLUDE_DEFAULT_ALLOCATOR
#define NK_INCLUDE_VERTEX_BUFFER_OUTPUT
#include "nuklear.h"

#include <malloc.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>

#define MAX_MEMORY 1024*1024*20  // 20MB

static void
calculator(struct nk_context *ctx)
{
    if (nk_begin(ctx, "Calculator", nk_rect(10, 10, 180, 250),
        NK_WINDOW_BORDER|NK_WINDOW_NO_SCROLLBAR|NK_WINDOW_MOVABLE))
    {
        static int set = 0, prev = 0, op = 0;
        static const char numbers[] = "789456123";
        static const char ops[] = "+-*/";
        static double a = 0, b = 0;
        static double *current = &a;

        {

            int len; char buffer[256];
        nk_layout_row_dynamic(ctx, 35, 1);
        len = _snprintf(buffer, 256, "%.2f", *current);
        nk_edit_string(ctx, NK_EDIT_SIMPLE, buffer, &len, 255, nk_filter_float);
        buffer[len] = 0;
        *current = atof(buffer);}

                if (nk_button_label(ctx, "C")) {
                    a = b = op = 0; current = &a; set = 0;
                } if (nk_button_label(ctx, "0")) {

                }
            } else if (((i+1) % 4)) {
                if (nk_button_text(ctx, &numbers[(i/4)*3+i%4], 1)) {
                    *current = *current * 10.0f + numbers[(i/4)*3+i%4] - '0';
                    set = 0;
                }
            } else if (nk_button_text(ctx, &ops[i/4], 1)) {

                        current = &b;
                    } else {
                        prev = op;
                        solve = 1;
                    }
                }
                op = ops[i/4];
                set = 1;
            }
        }
        if (solve) {
            if (prev == '+') a = a + b;
            if (prev == '-') a = a - b;
            if (prev == '*') a = a * b;
            if (prev == '/') a = a / b;
            current = &a;
            if (set) current = &b;
            b = 0; set = 0;
        }
    }
    nk_end(ctx);
}

int main()
{

    struct nk_context ctx;
    struct nk_user_font font;

    nk_init_default(&ctx, NULL);

    calculator(&ctx);
    return 0;
}

I found the library need a font to load by function nk_init_default, But How Can I use struct nk_user_font to load a specific font in folder extra_font? there are no detailed documentations. and run-welled demo.

Edit(vurtun): fixed code formatting

[jacmoe]

The actual demos are in the subdirectories of the demo directory :) There are 10 demos in a dir each in the demo dir.

You are not setting up your graphics and you are not looping. But check out the demo code to see how it's done.

@AlexiaChen like @jacmoe already said so far you only have the platform independent part but you are missing the platform depended part. Basically I would suggest first giving the platform demo of choice inside the /demo folder a look. Each demo optionally includes the calculator and provides a basic overview on how to bind nuklear to a platform. If you get one of my demos to run you basically just have to add your specific UI code.

@vurtun Thanks, I kooked through the demo directory, and not checked GUI sub directory,sorry. Let me see How it works.
