## API
### Context
Contexts are the main entry point and the majestro of nuklear and contain all required state.
They are used for window, memory, input, style, stack, commands and time management and need
to be passed into all nuklear GUI specific functions.
#### Usage
To use a context it first has to be initialized which can be achieved by calling
one of either `nk_init_default`, `nk_init_fixed`, `nk_init`, `nk_init_custom`.
Each takes in a font handle and a specific way of handling memory. Memory control
hereby ranges from standard library to just specifying a fixed sized block of memory
which nuklear has to manage itself from.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
struct nk_context ctx;
nk_init_xxx(&ctx, ...);
while (1) {
// [...]
nk_clear(&ctx);
}
nk_free(&ctx);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#### Reference
Function | Description
--------------------|---------------------------
__nk_init_default__ | Initializes context with standard library memory allocation (malloc,free)
__nk_init_fixed__ | Initializes context from single fixed size memory block
__nk_init__ | Initializes context with memory allocator callbacks for alloc and free
__nk_init_custom__ | Initializes context from two buffers. One for draw commands the other for window/panel/table allocations
__nk_clear__ | Called at the end of the frame to reset and prepare the context for the next frame
__nk_free__ | Shutdown and free all memory allocated inside the context
__nk_set_user_data__| Utility function to pass user data to draw command
#### nk_init_default
Initializes a `nk_context` struct with a default standard library allocator.
Should be used if you don't want to be bothered with memory management in nuklear.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
NK_API int nk_init_default(struct nk_context *ctx, const struct nk_user_font *font);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Parameter | Description
------------|-------------
__ctx__ | Must point to an either stack or heap allocated `nk_context` struct
__font__ | Must point to a previously initialized font handle for more info look at font documentation
Returns either `false(0)` on failure or `true(1)` on success.
#### nk_init_fixed
Initializes a `nk_context` struct from a single fixed size memory block
Should be used if you want complete control over nuklear's memory management.
Especially recommended for system with little memory or systems with virtual memory.
For the later case you can just allocate for example 16MB of virtual memory
and only the required amount of memory will actually be committed.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
NK_API int nk_init_fixed(struct nk_context *ctx, void *memory, nk_size size, const struct nk_user_font *font);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
!!! Warning
make sure the passed memory block is aligned correctly for `nk_draw_commands`.
Parameter | Description
------------|-------------
__ctx__ | Must point to an either stack or heap allocated `nk_context` struct
__memory__ | Must point to a previously allocated memory block
__size__ | Must contain the total size of __memory__
__font__ | Must point to a previously initialized font handle for more info look at font documentation
Returns either `false(0)` on failure or `true(1)` on success.
#### nk_init
Initializes a `nk_context` struct with memory allocation callbacks for nuklear to allocate
memory from. Used internally for `nk_init_default` and provides a kitchen sink allocation
interface to nuklear. Can be useful for cases like monitoring memory consumption.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
NK_API int nk_init(struct nk_context *ctx, struct nk_allocator *alloc, const struct nk_user_font *font);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Parameter | Description
------------|-------------
__ctx__ | Must point to an either stack or heap allocated `nk_context` struct
__alloc__ | Must point to a previously allocated memory allocator
__font__ | Must point to a previously initialized font handle for more info look at font documentation
Returns either `false(0)` on failure or `true(1)` on success.
#### nk_init_custom
Initializes a `nk_context` struct from two different either fixed or growing
buffers. The first buffer is for allocating draw commands while the second buffer is
used for allocating windows, panels and state tables.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
NK_API int nk_init_custom(struct nk_context *ctx, struct nk_buffer *cmds, struct nk_buffer *pool, const struct nk_user_font *font);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Parameter | Description
------------|-------------
__ctx__ | Must point to an either stack or heap allocated `nk_context` struct
__cmds__ | Must point to a previously initialized memory buffer either fixed or dynamic to store draw commands into
__pool__ | Must point to a previously initialized memory buffer either fixed or dynamic to store windows, panels and tables
__font__ | Must point to a previously initialized font handle for more info look at font documentation
Returns either `false(0)` on failure or `true(1)` on success.
#### nk_clear
Resets the context state at the end of the frame. This includes mostly
garbage collector tasks like removing windows or table not called and therefore
used anymore.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
NK_API void nk_clear(struct nk_context *ctx);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Parameter | Description
------------|-------------
__ctx__ | Must point to a previously initialized `nk_context` struct
#### nk_free
Frees all memory allocated by nuklear. Not needed if context was
initialized with `nk_init_fixed`.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
NK_API void nk_free(struct nk_context *ctx);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Parameter | Description
------------|-------------
__ctx__ | Must point to a previously initialized `nk_context` struct
#### nk_set_user_data
Sets the currently passed userdata passed down into each draw command.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
NK_API void nk_set_user_data(struct nk_context *ctx, nk_handle data);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Parameter | Description
------------|-------------
__ctx__ | Must point to a previously initialized `nk_context` struct
__data__ | Handle with either pointer or index to be passed into every draw commands
