Had to change some small things to make everything work for a
general case instead of vertex draw list only. Furthermore I
don't want a custom widget inside nuklear so I removed it.
Feel free to add it back into your own version.
Added a new command type 'NK_COMMAND_CUSTOM'.
A custom command contains a callback that will be called to fill the draw list.
Usage:
static void custom_convert(struct nk_draw_list *list,
short x, short y, unsigned short w, unsigned short h,
nk_handle callback_data){/*Fill draw list.*/}
[...]nk_begin[...]
nk_custom(ctx, customConvert, nk_handle_id(0));
The handle can be used to pass data.
These warnings appear on GCC for Windows only. There a lot of them. Doesn't matter, native compilation or crosscompile.
`nuklear.h:6836:9: warning: this decimal constant is unsigned only in ISO C90`
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?
When NDEBUG defined:
nuklear.h: In function 'nk_popup_begin':
nuklear.h:20753:22: warning: variable 'panel' set but not used [-Wunused-but-set-variable]
nuklear.h: In function 'nk_nonblock_begin':
nuklear.h:20850:22: warning: variable 'panel' set but not used [-Wunused-but-set-variable]
Added another version of `nk_tree` that does not store internal state
to hold the tree state (minimized/maximized). Main advantages is
possibily less memory consumptions and more user control.
In addition a new set of button overloads were added to directly pass
in a button style struct which allows an easier way to have custom
button visuals for specific buttons.
Added additional `nk_group` version which uses an external scrollbar
offset instead of internally managing the memory. In addition
`nk_list_view` is introduced which allows drawing huge lists inside a
`nk_group`(#269).
