Previously I packed standard library variable arguments as well as
file operation into one define `NK_INCLUDE_STANDARD_IO`. This caused
some problems and I split the define into two. So if you want the old
behavior you need to define `NK_INCLUDE_STANDARD_IO` as well as
`NK_INCLUDE_STANDARD_VARARGS`. If you only want file operations but
not variable arguments only define `NK_INCLUDE_STANDARD_IO` and
if you only want varargs but not file operations please only define
`NK_INCLUDE_STANDARD_VARARGS`.
I had a long standing bug inside nuklear which prevents you from
swapping out a font while the code is being build. This bug is now
fixed but the fix requires _ALL_ `nk_user_font` data structures
provided by `nk_style_set_font` to be persistent.
Since it was requested I added a small snippet showing how to create
notebook tabs (header with buttons, selecting content). The added
demo is basically just a combination of already existing widgets +
some small styling changes and can be extended to easily support
case with more tabs then space in the header part. I will have
to think about if it is possible to create an API for this without
taking away the simplicity of it.
It's now possible to define a specific color for each line or
column entry inside a chart. This purely extends the API and all
previous implementation still work.
All platform and renderbackend independent examples are now optional
demos for all platforms in `demo/`. Moving some demos from `example/`
provides an easier way to test GUI concepts for users and simplifies
maintenance.
First version supporting the new record and play feature which allows
to `record` a number of API calls and lets you replay them at a later
point of time. This could be the basis for creating an Editor and
other more advanced features. While I tested the functionality there
still could be a number of bugs and I would recommend waiting
until all bugs are removed before using it.
Fixed one of the small issues between C and C++. The handling of
enums. While C uses weak types and compiling `zr_flags` or
`enum zr_text_alignment` did not cause any problems, trying to do the
same with C++ results in errors or in this case a linking
error since while the function exist with `zr_flags` it does not
exist with `enum zr_text_alignment` (another problem of function
overloading...)
The conversion function from rgb color to hsv color was bugged and
provided wrong values. It is now fixed and hopefully is now correct.
In addition a number of utility functions have been added to make
conversion between user provided color format and zahnrads own
format easier.
While dividing previously spared me from a lot of work and problems
it is probably best to have everything working for every or as many
platforms as possible. Some platforms fail to provide good ways
to support everything (e.g.:X11 does not have pixmap clipping with
different width/height or alpha-blending) but all OpenGL demos
outside allegro (needs some additional work) should be able to run.
