Dmitry Hrabrov 7d52c0de67 Remove warning: 'nk_to_upper' defined but not used
There is function `NK_INTERN int nk_to_upper(int c)` in `UTIL` section. Implementation is almost the same to `NK_INTERN int nk_to_lower(int c)`. But only `nk_to_lower` used in Nuklear's code. To remove this warning we can: 
1) Comment i.e. remove `nk_to_upper` from code. But it can break someone's code, if he used it in module with `NK_IMPLEMENTATION` defined.
2) Hide it under define. Same. 
3) Just use it somewhere in code. 
I replaced two calls of `nk_to_lower` to `nk_to_upper`. It removes the warning, code works the same. The bad side - complication of the code. "Why `nk_to_upper` is used here, but not `nk_to_lower` as one line up?"
Maybe there exists better solution? Or just add the comment about this line to code?

Build Status

Nuklear

This is a minimal state immediate mode graphical user interface toolkit written in ANSI C and licensed under public domain. It was designed as a simple embeddable user interface for application and does not have any dependencies, a default renderbackend or OS window and input handling but instead provides a very modular library approach by using simple input state for input and draw commands describing primitive shapes as output. So instead of providing a layered library that tries to abstract over a number of platform and render backends it only focuses on the actual UI.

Features

  • Immediate mode graphical user interface toolkit
  • Single header library
  • Written in C89 (ANSI C)
  • Small codebase (~17kLOC)
  • Focus on portability, efficiency and simplicity
  • No dependencies (not even the standard library if not wanted)
  • Fully skinnable and customizable
  • Low memory footprint with total memory control if needed or wanted
  • UTF-8 support
  • No global or hidden state
  • Customizable library modules (you can compile and use only what you need)
  • Optional font baker and vertex buffer output

Building

This library is self contained in one single header file and can be used either in header only mode or in implementation mode. The header only mode is used by default when included and allows including this header in other headers and does not contain the actual implementation.

The implementation mode requires to define the preprocessor macro NK_IMPLEMENTATION in one .c/.cpp file before #includeing this file, e.g.:

#define NK_IMPLEMENTATION
#include "nuklear.h"

IMPORTANT: Every time you include "nuklear.h" you have to define the same optional flags. This is very important not doing it either leads to compiler errors or even worse stack corruptions.

Example

/* init gui state */
struct nk_context ctx;
nk_init_fixed(&ctx, calloc(1, MAX_MEMORY), MAX_MEMORY, &font);

enum {EASY, HARD};
int op = EASY;
float value = 0.6f;
int i =  20;

if (nk_begin(&ctx, "Show", nk_rect(50, 50, 220, 220),
    NK_WINDOW_BORDER|NK_WINDOW_MOVABLE|NK_WINDOW_CLOSABLE)) {
    /* fixed widget pixel width */
    nk_layout_row_static(&ctx, 30, 80, 1);
    if (nk_button_label(&ctx, "button")) {
        /* event handling */
    }

    /* fixed widget window ratio width */
    nk_layout_row_dynamic(&ctx, 30, 2);
    if (nk_option_label(&ctx, "easy", op == EASY)) op = EASY;
    if (nk_option_label(&ctx, "hard", op == HARD)) op = HARD;

    /* custom widget pixel width */
    nk_layout_row_begin(&ctx, NK_STATIC, 30, 2);
    {
        nk_layout_row_push(&ctx, 50);
        nk_label(&ctx, "Volume:", NK_TEXT_LEFT);
        nk_layout_row_push(&ctx, 110);
        nk_slider_float(&ctx, 0, &value, 1.0f, 0.1f);
    }
    nk_layout_row_end(&ctx);
}
nk_end(&ctx);

Big thank you to Omar Cornut (ocornut@github) for his imgui library and giving me the inspiration for this library, Casey Muratori for handmade hero and his original immediate mode graphical user interface idea and Sean Barret for his amazing single header libraries which restored my faith in libraries and brought me to create some of my own.
