I removed the default vertex type and instead create an API to allow the
user to specify the vertex struct layout. Of course you are still
bound on what the library actual has on vertex data but the type and
sequence of the data is now configurable. This commit is quite
experiental and could introduce some bugs, but so far it look fine.
Nuklear now has three different property versions for int, float and
added by this commit a double version. Internally an additional change
happend. Now the type of the property is actually taken into account
and floating pointer errors due to casting are less of an issue.
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`.
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.
Previously if you use `nk_edit_string` and use flag
`NK_EDIT_CLIPBOARD`, callbacks were not passed. I only tested it with
`nk_edit_buffer` and set the callbacks directly. This wrong behavior
is now fixed and should work copy & paste should behave correctly.
This is the first release version of nuklear (previously: zahnrad).
As for those who no the old version will notice: a lot has changed.
Most obvious should be the two biggest changes. First the name change
because I got critique that the name is hard to comprehend and
remember (understandable for non-germans) and the second is the
transistion from four files (zahnrad.h, zahnrad.c, stb_truetype
and stb_rect_pack) to one single header library file nuklear.h.
I am not 100% convinced that using a single header library is the
right choice here but so far I haven't encountered any problems.
Noticable should be as well that nuklear now directly embeds three
stb libraries: stb_truetype, stb_rect_pack and stb_textedit. Like
in previous versions the first two are optional and the library
can be compiled without. stb_textedit on the other hand powers
the text edit implementation for single as well as multiline
text manipulation. The text edit implementation is still relative
new and untested so you can expect some bugs I have not found yet.
In the demo department a lot changed as well. All platform demos
now don't compile one big demo but instead contain a simple
demo and small abstraction layer over the platform. Main benefit is
better understandablity improved ease of use. The old demo
is now split up and transfered into the example folder while each part
is self contained and compileable. (All examples use glfw I don't now
if this is the best platform but it is at least the simplest.
I also removed the apple demo because I don't have an apple system
and cannot make sure the new version runs with the old version.
Finally a lot of small bugs have been fixed as well as bugs found by
clang analyzer and coverity.
This commit extends the optional currently existing low level font
baking API with another more high level font atlas API.
The font atlas takes away some fine grained memory control from the
user but is easier to use and to understand than the lower level API.
I added combined with the font atlas a optional default font which
allows running the library without a user provided truetype font.
While user friendly it is quite big (~12kb) so I added a compiler flag
to remove it from the library while compiling if not wanted.
Finally I added some additional compiler flags to allow easier to use
APIs. The downside is that all of them require the standard library,
so if you don't want to add the standard C library I would recommend
deactivating all flags marked as standard library flags.
Previous visual changes in the library were quite limited with some
colors and some global properties. This commit changes all that and
provides way more control over every widgets visual appearance.
Changes include extended color selection, per widget properties and
the possibility to use skinning.
While the new API allows for a lot more control it is currently quite
low level and needs a lot more testing and probably another higher
level style API to make changes in code easier. I also had to remove
the style modification code inside the demo and will probably first
try to write another higher level API before adding it back in.
This commit also include some breaking changes to existing code like
the missing style stack API and some widget names changes due to
added granularity granted by the rewritten style.
